Switch Installation

Rack Mount Hardware Installation
The switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipment. Attach the mounting brackets at the switch’s front panel (one on each side), and secure them with the provided screws. Note: The switch model may be different than the one shown in the example illustrations.
Then, use screws provided with the equipment rack to mount each switch in the rack.

Managed Industrial L2 Switches
DIN-Rail Installation
The site where the switch will be installed may greatly affect its performance. When installing, consider the following pointers: Note: The switch model may be different than the one shown in the example illustrations.
· Install the switch in the appropriate location. Please refer to the technical specifications at the end of this manual for the acceptable operating temperature and humidity ranges.
· Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.
· Install the switch in a location that is not affected by strong electromagnetic field generators (such as motors), vibration, dust, and direct sunlight.
· Leave at least 10cm of space at the front and rear of the switch for ventilation.
Fasten the DIN-Rail bracket to the rear of the switch using the included fasteners/screws. Note: The DIN-Rail bracket may already be installed to your switch when received.
The movable clip at the top of the DIN-Rail bracket should be on top.

TRENDnet User’s Guide
The switch can be installed to a 35mm (W) DIN-Rail located in cabinet, rack, or enclosure.
To mount the switch to a DIN-Rail using the attached DIN-Rail bracket, position the switch in front of the DIN-Rail and hook the bracket over the top of the rail. Then rotate the switch downward towards the rail until your hear a click indicating the bracket is secure and locked into place.

Managed Industrial L2 Switches
Install power supply connections
Connect the power supply (sold separate, e.g. TRENDnet TI-S24048) to the switch terminal block as shown below. Optional: The switch chassis can also be connected to a known ground point for additional safety and protection (grounding wire not included). Note: Polarities V+ and V- should match between power supply and connections to switch terminal block. Note: The models in the image may be different than your specific model.

To unmount the switch from the DIN-Rail, slightly pull the switch downwards to clear the bottom of the DIN-Rail and rotate away from DIN-Rail to unmount.

Basic IP Configuration

Managed Industrial L2 Switches

2. Assign a static IP address to your computer’s network adapter in the subnet of 192.168.10.x (e.g. 192.168.10.25) and a subnet mask of 255.255.255.0.
3. Open your web browser, and type the IP address of the switch in the address bar, and then press Enter. The default IP address is 192.168.10.200.

To properly connect fiber cabling: Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.
Note: When inserting the cable, be sure the tab on the plug clicks into position to ensure that it is properly seated.

4. Enter the User Name and Password, and then click Login. By default: User Name: admin Password: admin Note: User name and password are case sensitive.

SNTP
The Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. A less complex implementation of NTP, using the same protocol but without requiring the storage of state over extended periods of time is known as the Simple Network Time Protocol (SNTP). NTP provides Coordinated Universal Time (UTC). No information about time zones or daylight saving time is transmitted; this information is outside its scope and must be obtained separately.
UDP Port: 123.

Daylight saving is a period from late spring to early fall when many countries set their clocks ahead of normal local time by one hour to give more daytime light in the evening.

Note: 1. 2.
3.
4. 5.
6.
7.

The SNTP server always replies the UTC current time. When the Switch receives the SNTP reply time, the Switch will adjust the time with the time zone configuration and then configure the time to the Switch. If the time server’s IP address is not configured, the Switch will not send any SNTP request packets. If no SNTP reply packets, the Switch will retry every 10 seconds forever. If the Switch has received SNTP reply, the Switch will re-get the time from NTP server every 24 hours. If the time zone and time NTP server have been changed, the Switch will repeat the query process. No default SNTP server.

MAC Management

Dynamic Address: The MAC addresses are learnt by the switch. When the switch receives frames, it will record the source MAC, the received port and the VLAN in the address table with an age time. When the age time is expired, the address entry will be removed from the address table.
Static Address: The MAC addresses are configured by users. The static addresses will not be aged out by the switch; it can be removed by user only. The maximum static address entry is up to 256.
The MAC Table (a MAC table is also known as a filtering database) shows how frames are forwarded or filtered across the Switch’s ports. When a device (which may belong to a VLAN group) sends a packet which is forwarded to a port on the Switch, the MAC address of the device is shown on the Switch’s MAC Table. It also shows whether the MAC address is dynamic (learned by the Switch) or static (manually entered). The Switch uses the MAC Table to determine how to forward frames. See the following figure.
1. The Switch examines the received frame and learns the port from which this source MAC address came.
2. The Switch checks to see if the frame’s destination MAC address matches a source MAC address already learnt in the MAC Table. If the Switch has already learnt the port for this MAC address, then it forwards the frame to that port. If the Switch has not already learnt the port for this MAC address, then the frame is flooded to all ports. If too much port flooding, it may lead to network congestion. If the Switch has already learnt the port for this MAC address, but the destination port is the same as the port it came in on, then it filters the frame.

Port Mirror

Port-based Mirroring
The Port-Based Mirroring is used on a network switch to send a copy of network packets sent/received on one or a range of switch ports to a network monitoring connection on another switch port (Monitor to Port). This is commonly used for network appliances that require monitoring of network traffic, such as an intrusion-detection system.
Port Mirroring, together with a network traffic analyzer, helps to monitor network traffic. Users can monitor the selected ports (Source Ports) for egress and/or ingress packets.
Source Mode: Ingress : The received packets will be copied to the monitor port. Egress : The transmitted packets will be copied to the monitor port. Both : The received and transmitted packets will be copied to the monitor
port. Note:
1. The monitor port cannot be a trunk member port. 2. The monitor port cannot be ingress or egress port. 3. If the Port Mirror function is enabled, the Monitor-to Port can receive mirrored
packets only. 4. If a port has been configured as a source port and then user configures the port
as a destination port, the port will be removed from the source ports automatically.

· Duplex mode A duplex communication system is a system composed of two connected parties or devices that can communicate with one another in both directions. Half Duplex: A half-duplex system provides for communication in both directions, but only one direction at a time (not simultaneously). Typically, once a party begins receiving a signal, it must wait for the transmitter to stop transmitting, before replying.
Full Duplex: A full-duplex, or sometimes double-duplex system, allows communication in both directions, and, unlike half-duplex, allows this to happen simultaneously. Land-line telephone networks are full-duplex, since they allow both callers to speak and be heard at the same time.
· Loopback Test A loopback test is a test in which a signal in sent from a communications device and returned (looped back) to it as a way to determine whether the device is working right or
© Copyright 2018 TRENDnet. All Rights Reserved.

Managed Industrial L2 Switch
as a way to pin down a failing node in a network. One type of loopback test is performed using a special plug, called a wrap plug that is inserted in a port on a communications device. The effect of a wrap plug is to cause transmitted (output) data to be returned as received (input) data, simulating a complete communications circuit using a single computer.
· Auto MDI-MDIX Auto-MDIX (automatic medium-dependent interface crossover) is a computer networking technology that automatically detects the required cable connection type (straight-through or crossover) and configures the connection appropriately, thereby removing the need for crossover cables to interconnect switches or connecting PCs peerto-peer. When it is enabled, either type of cable can be used or the interface automatically corrects any incorrect cabling. For Auto-MDIX to operate correctly, the speed on the interface and duplex setting must be set to “auto”. Auto-MDIX was developed by HP engineers Dan Dove and Bruce Melvin.
· Auto Negotiation Auto (auto-negotiation) allows one port to negotiate with a peer port automatically to obtain the connection speed and duplex mode that both ends support. When autonegotiation is turned on, a port on the Switch negotiates with the peer automatically to determine the connection speed and duplex mode.
If the peer port does not support auto-negotiation or turns off this feature, the Switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the Switch’s auto-negotiation is turned off, a port uses the preconfigured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer port are the same in order to connect.
· Flow Control A concentration of traffic on a port decreases port bandwidth and overflows buffer memory causing packet discards and frame losses.IEEE802.3x flow control is used in full duplex mode to send a pause signal to the sending port, causing it to temporarily stop sending signals when the receiving port memory buffers fill and resend later.
40

TRENDnet User’s Guide
The Switch uses IEEE802.3x flow control in full duplex mode and backpressure flow control in half duplex mode. IEEE802.3x flow control is used in full duplex mode to send a pause signal to the sending port, causing it to temporarily stop sending signals when the receiving port memory buffers fill. Back Pressure flow control is typically used in half duplex mode to send a “collision” signal to the sending port (mimicking a state of packet collision) causing the sending port to temporarily stop sending signals and resend later. Note: 1000 Base-T doesn’t support force mode. · Cable Test. This feature determines the quality of the cables, shorts, and cable impedance mismatch, bad connectors, termination mismatch, and bad magnetics. The feature can work on the copper Ethernet cable only. Default Settings
The default port Speed & Duplex is auto for all ports. The default port Flow Control is Off for all ports.

Advanced Settings

Bandwidth Control
QoS Each egress port can support up to 8 transmit queues. Each egress transmit queue contains a list specifying the packet transmission order. Every incoming frame is forwarded to one of the 8 egress transmit queues of the assigned egress port, based on its priority. The egress port transmits packets from each of the 8 transmit queues according to a configurable scheduling algorithm, which can be a combination of Strict Priority (SP) and/or Weighted Round Robin (WRR).
Typically, networks operate on a best-effort delivery basis, which means that all traffic has equal priority and an equal chance of being delivered in a timely manner. When congestion occurs, all traffic has an equal chance of being dropped.
When you configure the QoS feature, you can select specific network traffic, prioritize it according to its relative importance, and use congestion- management and congestionavoidance techniques to give preferential treatment. Implementing QoS in your network makes network performance more predictable and bandwidth utilization more effective.
The Switch supports 802.1p priority queuing. The Switch has 8 priority queues. These priority queues are numbered from 7 (Class 7) — the highest priority queue — to 0 (Class 0) — the lowest priority queue. The eight priority tags specified in IEEE 802.1p (p0 to p7) are mapped to the Switch’s priority queues as follows:
Priority : 0 1 2 3 4 5 6 7 Queue : 2 0 1 3 4 5 6 7
Priority scheduling is implemented by the priority queues stated above. The Switch will empty the four hardware priority queues in order, beginning with the highest priority queue, 7, to the lowest priority queue, 0. Each hardware queue will transmit all of the packets in its buffer before permitting the next lower priority to transmit its packets.
© Copyright 2018 TRENDnet. All Rights Reserved.

Managed Industrial L2 Switch

When the lowest hardware priority queue has finished transmitting all of its packets, the highest hardware priority queue will begin transmitting any packets it may have received.

QoS Enhancement
You can configure the Switch to prioritize traffic even if the incoming packets are not marked with IEEE 802.1p priority tags or change the existing priority tags based on the criteria you select. The Switch allows you to choose one of the following methods for assigning priority to incoming packets on the Switch:
802.1p Tag Priority – Assign priority to packets based on the packet’s 802.1p tagged priority.
Port Based QoS – Assign priority to packets based on the incoming port on the Switch.
DSCP Based QoS – Assign priority to packets based on their Differentiated Services Code Points (DSCPs).

Note: Advanced QoS methods only affect the internal priority queue mapping for the Switch. The Switch does not modify the IEEE 802.1p value for the egress frames. You can choose one of these ways to alter the way incoming packets are prioritized or you can choose not to use any QoS enhancement setting on the Switch.

802.1p Priority
When using 802.1p priority mechanism, the packet is examined for the presence of a valid 802.1p priority tag. If the tag is present, the packet is assigned to a programmable egress queue based on the value of the tagged priority. The tagged priority can be designated to any of the available queues.

Tag Protocol Identifier (TPID): a 16-bit field set to a value of 0x8100 in order to identify the frame as an IEEE 802.1Q-tagged frame.
Tag Control Information (TCI) Priority Code Point (PCP): a 3-bit field which refers to the IEEE 802.1p priority. It indicates the frame priority level from 0 (lowest) to 7 (highest), which can be used to prioritize different classes of traffic (voice, video, data, etc.). Canonical Format Indicator (CFI): a 1-bit field. If the value of this field is 1, the MAC address is in non- canonical format. If the value is 0, the MAC address is in canonical format. It is always set to zero for Ethernet switches. CFI is used for compatibility between Ethernet and Token Ring networks. If a frame received at an Ethernet port has a CFI set to 1, then that frame should not be bridged to an untagged port. VLAN Identifier (VID): a 12-bit field specifying the VLAN to which the frame belongs. A value of 0 means that the frame doesn’t belong to any VLAN; in this case the 802.1Q tag specifies only a priority and is referred to as a priority tag. A value of hex 0xFFF is reserved for implementation use. All other values may be used as VLAN identifiers, allowing up to 4094 VLANs. On bridges, VLAN 1 is often reserved for management.

DiffServ (DSCP) Differentiated Services or DiffServ is a computer networking architecture that specifies a simple, scalable and coarse-grained mechanism for classifying, managing network traffic and providing Quality of Service (QoS) guarantees on modern IP networks. DiffServ can, for example, be used to provide low-latency, guaranteed service (GS) to critical network traffic such as voice or video while providing simple best-effort traffic guarantees to noncritical services such as web traffic or file transfers.
Differentiated Services Code Point (DSCP) is a 6-bit field in the header of IP packets for packet classification purposes. DSCP replaces the outdated IP precedence, a 3-bit field in the Type of Service byte of the IP header originally used to classify and prioritize types of traffic.
When using the DiffServ priority mechanism, the packet is classified based on the DSCP field in the IP header. If the tag is present, the packet is assigned to a programmable egress queue based on the value of the tagged priority. The tagged priority can be designated to any of the available queues.

IP Header Type of Service: 8 bits

The Type of Service provides an indication of the abstract parameters of the quality of service desired. These parameters are to be used to guide the selection of the actual service parameters when transmitting a datagram through a particular network. Several networks offer service precedence, which somehow treats high precedence traffic as more important than other traffic (generally by accepting only traffic above certain precedence at time of high load). The major choice is a three way tradeoff between lowdelay, high- reliability, and high-throughput.

Bits 0-2: Precedence.

Bit 3:

0 = Normal Delay,

1 = Low Delay.

Bits 4:

0 = Normal Throughput, 1 = High Throughput.

Bits 5:

0 = Normal Reliability,

1 = High Reliability.

Bit 6-7:

Reserved for Future Use.

111 – Network Control 110 – Internetwork Control 101 – CRITIC/ECP 100 – Flash Override 011 – Flash 010 – Immediate 001 – Priority 000 – Routine

The use of the Delay, Throughput, and Reliability indications may increase the cost (in some sense) of the service. In many networks better performance for one of these parameters is coupled with worse performance on another. Except for very unusual cases at most two of these three indications should be set.

Managed Industrial L2 Switch

The type of service is used to specify the treatment of the datagram during its transmission through the internet system. Example mappings of the internet type of service to the actual service provided on networks such as AUTODIN II, ARPANET, SATNET, and PRNET is given in “Service Mappings”.

The Network Control precedence designation is intended to be used within a network only. The actual use and control of that designation is up to each network. The Internetwork Control designation is intended for use by gateway control originators only.

If the actual use of these precedence designations is of concern to a particular network, it is the responsibility of that network to control the access to, and use of, those precedence designations.

Queuing Algorithms Queuing algorithms allow switches to maintain separate queues for packets from each individual source or flow and prevent a source from monopolizing the bandwidth.
Strict-Priority (SPQ) The packets on the high priority queue are always service firstly.
Weighted round robin (WRR)
46

TRENDnet User’s Guide

Round Robin scheduling services queues on a rotating basis and is activated only when a port has more traffic than it can handle. A queue is given an amount of bandwidth irrespective of the incoming traffic on that port. This queue then moves to the back of the list. The next queue is given an equal amount of bandwidth, and then moves to the end of the list; and so on, depending on the number of queues being used. This works in a looping fashion until a queue is empty.
Weighted Round Robin (WRR) scheduling uses the same algorithm as round robin scheduling, but services queues based on their priority and queue weight (the number you configure in the queue Weight field) rather than a fixed amount of bandwidth. WRR is activated only when a port has more traffic than it can handle. Queues with larger weights get more service than queues with smaller weights. This queuing mechanism is highly efficient in that it divides any available bandwidth across the different traffic queues and returns to queues that have not yet emptied.
Default Settings QoS mode : High First (SPQ) The mappings of the Priority to Queue are: PRIO 0 ==> COSQ 2 PRIO 1 ==> COSQ 0 PRIO 2 ==> COSQ 1 PRIO 3 ==> COSQ 3 PRIO 4 ==> COSQ 4 PRIO 5 ==> COSQ 5 PRIO 6 ==> COSQ 6 PRIO 7 ==> COSQ 7

Rate Limitation Storm Control A broadcast storm means that your network is overwhelmed with constant broadcast or multicast traffic. Broadcast storms can eventually lead to a complete loss of network connectivity as the packets proliferate.
Storm Control protects the Switch bandwidth from flooding packets, including broadcast packets, multicast packets, and destination lookup failure (DLF). The Rate is a threshold that limits the total number of the selected type of packets. For example, if the broadcast and multicast options are selected, the total amount of packets per second for those two types will not exceed the limit value.

Broadcast storm control limits the number of broadcast, multicast and unknown unicast (also referred to as Destination Lookup Failure or DLF) packets the Switch receives per second on the ports. When the maximum number of allowable broadcast, multicast and unknown unicast packets is reached per second, the subsequent packets are discarded. Enable this feature to reduce broadcast, multicast and unknown unicast packets in your network.

IGMP Snooping

IGMP Snooping The IGMP snooping is for multicast traffic. The Switch can passively snoop on IGMP packets transferred between IP multicast routers/switches and IP multicast hosts to learn the IP multicast group membership. It checks IGMP packets passing through it, picks out the group registration information, and configures multicasting accordingly. IGMP snooping allows the Switch to learn multicast groups without you having to manually configure them.
The Switch can passively snoop on IGMP packets transferred between IP multicast routers/switches and IP multicast hosts to learn the IP multicast group membership. It checks IGMP packets passing through it, picks out the group registration information, and configures multicasting accordingly. IGMP snooping allows the Switch to learn multicast groups without you having to manually configure them. The Switch forwards multicast traffic destined for multicast groups (that it has learned from IGMP snooping or that you have manually configured) to ports that are members of that group. IGMP snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your Switch.
The Switch can perform IGMP snooping on up to 4094 VLANs. You can configure the Switch to automatically learn multicast group membership of any VLANs. The Switch then performs IGMP snooping on the first VLANs that send IGMP packets. Alternatively, you can specify the VLANs that IGMP snooping should be performed on. This is referred to as fixed mode. In fixed mode the Switch does not learn multicast group membership of any VLANs other than those explicitly added as an IGMP snooping VLAN.
Immediate Leave
When you enable IGMP Immediate-Leave processing, the switch immediately removes a port when it detects an IGMP version 2 leave message on that port. You should use the Immediate-Leave feature only when there is a single receiver present on every port in the VLAN. (Immediate Leave is only supported on IGMP Version 2 hosts).

Managed Industrial L2 Switch
The switch uses IGMP snooping Immediate Leave to remove from the forwarding table an interface that sends a leave message without the switch sending group-specific queries to the interface. The VLAN interface is pruned from the multicast tree for the multicast group specified in the original leave message. Immediate Leave ensures optimal bandwidth management for all hosts on a switched network, even when multiple multicast groups are simultaneously in use.
Fast Leave The switch allow user to configure a delay time. When the delay time is expired, the switch removes the interface from the multicast group.
Last Member Query Interval Last Member Query Interval: The Last Member Query Interval is the Max Response Time inserted into Group-Specific Queries sent in response to Leave Group messages, and is also the amount of time between Group-Specific Query messages.
Without Immediate Leave, when the switch receives an IGMP leave message from a subscriber on a receiver port, it sends out an IGMP specific query on that port and waits for IGMP group membership reports. If no reports are received in a configured time period, the receiver port is removed from multicast group membership.
IGMP Querier There is normally only one Querier per physical network. All multicast routers start up as a Querier on each attached network. If a multicast router hears a Query message from a router with a lower IP address, it MUST become a Non-Querier on that network. If a router has not heard a Query message from another router for [Other Querier Present Interval], it resumes the role of Querier. Routers periodically [Query Interval] send a General Query on each attached network for which this router is the Querier, to solicit membership information. On startup, a router SHOULD send [Startup Query Count] General Queries spaced closely together [Startup Query Interval] in order to quickly and reliably determine membership information. A General Query is addressed to the allsystems multicast group (224.0.0.1), has a Group Address field of 0, and has a Max Response Time of [Query Response Interval].

TRENDnet User’s Guide
Port IGMP Querier Mode Auto:
The Switch uses the port as an IGMP query port if the port receives IGMP query packets.
Fixed: The Switch always treats the port(s) as IGMP query port(s). This is for when connecting an IGMP multicast server to the port(s). The Switch always forwards the client’s report/leave packets to the port. Normally, the port is connected to an IGMP server.
Edge: The Switch does not use the port as an IGMP query port. The IGMP query packets received by this port will be dropped. Normally, the port is connected to an IGMP client.
Note: The Switch will forward the IGMP join and leave packets to the query port.
Configurations: Users can enable/disable the IGMP Snooping on the Switch. Users also can enable/disable the IGMP Snooping on a specific VLAN. If the IGMP Snooping on the Switch is disabled, the IGMP Snooping is disabled on all VLANs even some of the VLAN IGMP Snooping are enabled.
Default Settings If received packets are not received after 400 seconds, all multicast entries will be deleted. The default global IGMP snooping state is disabled. The default VLAN IGMP snooping state is disabled for all VLANs. The unknown multicast packets will be dropped. The default port Immediate Leave state is disabled for all ports.

Multicast Address A multicast address is associated with a group of interested receivers. According to RFC 3171, addresses 224.0.0.0 to 239.255.255.255, the former Class D addresses, are designated as multicast addresses in IPv4.
The IANA owns the OUI MAC address 01:00:5e, therefore multicast packets are delivered by using the Ethernet MAC address range 01:00:5e:00:00:00 – 01:00:5e:7f:ff:ff. This is 23 bits of available address space.
56

TRENDnet User’s Guide
The first octet (01) includes the broadcast/multicast bit. The lower 23 bits of the 28-bit multicast IP address are mapped into the 23 bits of available Ethernet address space. This means that there is ambiguity in delivering packets. If two hosts on the same subnet each subscribe to a different multicast group whose address differs only in the first 5 bits, Ethernet packets for both multicast groups will be delivered to both hosts, requiring the network software in the hosts to discard the unrequired packets.

Class Address Range Class A 1.0.0.1 to 126.255.255.254 Class B 128.1.0.1 to 191.255.255.254 Class C 192.0.1.1 to 223.255.254.254 Class D 224.0.0.0 to 239.255.255.255 Class E 240.0.0.0 to 254.255.255.254

The port isolation is a port-based virtual LAN feature. It partitions the switching ports into virtual private domains designated on a per port basis. Data switching outside of the port’s private domain is not allowed. It will ignore the packets’ tag VLAN information.

This feature is a per port setting to configure the egress port(s) for the specific port to forward its received packets. If the CPU port (port 0) is not an egress port for a specific port, the host connected to the specific port cannot manage the Switch.

If you wish to allow two subscriber ports to talk to each other, you must define the egress port for both ports. CPU refers to the Switch management port. By default it forms a VLAN with all Ethernet ports. If it does not form a VLAN with a particular port then the Switch cannot be managed from that port.

Example: If you want to allow port-1 and port-3 to talk to each other, you must configure as below:
DEVICE_NAME#interface 1/0/1 DEVICE_NAME#port-isolation ports 3 DEVICE_NAME#exit
; Allow the port-1 to send its ingress packets to port-3.

DEVICE_NAME#interface 1/0/3 DEVICE_NAME#port-isolation ports 1 DEVICE_NAME#exit
; Allow the port-3 to send its ingress packets to port-1

802.1Q VLAN
A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that communicate as if they were attached to the Broadcast domain, regardless of their physical location. A VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if they are not located on the same network switch. Network reconfiguration can be done through software instead of physically relocating devices.

VID- VLAN ID is the identification of the VLAN, which is basically used by the standard 802.1Q. It has 12 bits and allow the identification of 4096 (2^12) VLANs. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN configurations are 4,094.

Managed Industrial L2 Switch

A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame across bridges – they are not confined to the switch on which they were created. The VLANs can be created statically by hand or dynamically through GVRP. The VLAN ID associates a frame with a specific VLAN and provides the information that switches need to process the frame across the network. A tagged frame is four bytes longer than an untagged frame and contains two bytes of TPID (Tag Protocol Identifier, residing within the type/length field of the Ethernet frame) and two bytes of TCI (Tag Control Information, starts after the source address field of the Ethernet frame).
The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet switches. If a frame received at an Ethernet port has a CFI set to 1, then that frame should not be forwarded as it is to an untagged port. The remaining twelve bits define the VLAN ID, giving a possible maximum number of 4,096 VLANs. Note that user priority and VLAN ID are independent of each other. A frame with VID (VLAN Identifier) of null (0) is called a priority frame, meaning that only the priority level is significant and the default VID of the ingress port is given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN configurations are 4,094.

· Forwarding Tagged and Untagged Frames
Each port on the Switch is capable of passing tagged or untagged frames. To forward a frame from an 802.1Q VLAN-aware switch to an 802.1Q VLAN-unaware switch, the Switch first decides where to forward the frame and then strips off the VLAN tag. To forward a frame from an 802.1Q VLAN-unaware switch to an 802.1Q VLAN-aware switch, the Switch first decides where to forward the frame, and then inserts a VLAN tag reflecting the ingress port’s default VID. The default PVID is VLAN 1 for all ports, but this can be changed.
A broadcast frame (or a multicast frame for a multicast group that is known by the system) is duplicated only on ports that are members of the VID (except the ingress port itself), thus confining the broadcast to a specific domain.

TRENDnet User’s Guide
· 802.1Q Port base VLAN With port-based VLAN membership, the port is assigned to a specific VLAN independent of the user or system attached to the port. This means all users attached to the port should be members of the same VLAN. The network administrator typically performs the VLAN assignment. The port configuration is static and cannot be automatically changed to another VLAN without manual reconfiguration.
As with other VLAN approaches, the packets forwarded using this method do not leak into other VLAN domains on the network. After a port has been assigned to a VLAN, the port cannot send to or receive from devices in another VLAN without the intervention of a Layer 3 device.
The device that is attached to the port likely has no understanding that a VLAN exists. The device simply knows that it is a member of a subnet and that the device should be able to talk to all other members of the subnet by simply sending information to the cable segment. The switch is responsible for identifying that the information came from a specific VLAN and for ensuring that the information gets to all other members of the VLAN. The switch is further responsible for ensuring that ports in a different VLAN do not receive the information.
This approach is quite simple, fast, and easy to manage in that there are no complex lookup tables required for VLAN segmentation. If port-to-VLAN association is done with an application-specific integrated circuit (ASIC), the performance is very good. An ASIC allows the port-to-VLAN mapping to be done at the hardware level.
Default Settings The default PVID is 1 for all ports. The default Acceptable Frame is All for all ports. All ports join in the VLAN 1.
Notice: The maximum VLAN group is 4094.

MAC VLAN The MAC base VLAN allows users to create VLAN with MAC address. The MAC address can be the leading three or more bytes of the MAC address. For example, 00:01:02 or 00:03:04:05 or 00:01:02:03:04:05.

When the Switch receives packets, it will compare MAC-based VLAN configures. If the SA is matched the MAC-based VLAN configures, the Switch replace the VLAN with user configured and them forward them.

For example: Configurations: 00:01:02, VLAN=23, Priority=2. The packets with SA=00:01:02:xx:xx:xx will be forwarded to VLAN 22 member ports.

Notices: The 802.1Q port base VLAN should be created first.

DHCP Options

DHCP Options, formally known as DHCP Options 82 is the “DHCP Relay Agent Information Option”. Option 82 was designed to allow a DHCP Relay Agent to insert circuit specific information into a request that is being forwarded to a DHCP server. Specifically the option works by setting two sub-options: Circuit ID and Remote ID.
The DHCP option 82 is working on the DHCP snooping or/and DHCP relay. The switch will monitor the DHCP packets and append some information as below to the DHCPDISCOVER and DHCPREQUEST packets. The switch will remove the DHCP Option 82 from the DHCPOFFER and DHCPACK packets. The DHCP server will assign IP domain to the client dependent on these information.
The maximum length of the information is 32 characters.
In residential, metropolitan Ethernet-access environments, DHCP can centrally manage the IP address assignments for a large number of subscribers. When the DHCP option-82 feature is enabled on the switch, a subscriber device is identified by the switch port through which it connects to the network (in addition to its MAC address). Multiple hosts on the subscriber LAN can be connected to the same port on the access switch and are uniquely identified.
When you enable the DHCP snooping information option 82 on the switch, this sequence of events occurs: · The host (DHCP client) generates a DHCP request and broadcasts it on the network. · When the switch receives the DHCP request, it adds the option-82 information in
the packet. The option-82 information contains the switch MAC address (the remote-ID suboption) and the port identifier, vlan-mod-port, from which the packet is received (the circuit-ID suboption). · If the IP address of the relay agent is configured, the switch adds the IP address in the DHCP packet. · The switch forwards the DHCP request that includes the option-82 field to the DHCP server. · The DHCP server receives the packet. If the server is option-82 capable, it can use the remote ID, the circuit ID, or both to assign IP addresses and implement policies, such as restricting the number of IP addresses that can be assigned to a single
65

TRENDnet User’s Guide

remote ID or circuit ID. Then the DHCP server echoes the option-82 field in the DHCP reply. · The DHCP server unicasts the reply to the switch if the request was relayed to the server by the switch. When the client and server are on the same subnet, the server broadcasts the reply. The switch verifies that it originally inserted the option-82 data by inspecting the remote ID and possibly the circuit ID fields. The switch removes the option-82 field and forwards the packet to the switch port that connects to the DHCP client that sent the DHCP request.

Circuit Form: The circuit form is a flexible architecture. It allows user to combine any information or the system configurations into the circuit sub- option.
The Circuit Form is a string format. And its maximum length is 100 characters.
The keyword, %SPACE, will be replaced with a space character. The other keywords get system configurations from the system and then replace the keyword and its leading code in the Circuit form. Eventually, the content of the circuit form is part of the payload on the DHCP option 82 packet.

Rules: · ·

The keyword must have a leading code %’. For example: %HOSTNAME. If there are any characters following the keywords, you must add+’ between the keyword and character. For example: %HOSTNAME+/.
If there are any characters before the keyword, you must add `+’ between the character and the keyword. For example: Test+%HOSTNAME.
