- Server discovery value is erased and changed to the default, redirector.online.spectraguard.net (primary) and wifi-security-server (secondary).
- All the VLAN configurations are lost.
- If a static IP is configured on the AP, the IP address is erased and DHCP mode is set. The factory default IP address of the AP is 169.254.11.74.
Install the Access Point
This chapter contains the stepwise procedure to install the access point (AP).
Zero-Configuration of the Access Point
Zero-configuration is supported under the following conditions:
- The device is in AP mode with background scanning on and no SSID configured.
- A DNS entry wifi-security-server is set up on all the DNS servers. This entry should point to the IP address of the server. By default, the AP looks for the DNS entry wifi-security-server.
- The AP is on a subnet that is DHCP enabled.
Important: If the AP is on a network segment that is separated from the server
by a firewall, you must first open port 3851 for bidirectional User Datagram
Protocol (UDP) and Transport Control Protocol (TCP) traffic on that firewall.
This port number is assigned to Arista Networks.
Zero-configuration cannot work if multiple APs are set up to connect to
multiple servers. In this case, the APs must be configured manually. For
details on how to configure an AP manually, see the Access Point Configuration
Guide on our website at https://www.arista.com/en/support/product-
documentation .
Take a configured AP; that is, ensure that a static IP is assigned to the AP
or the settings have been changed for DHCP. Note the MAC address and the IP
address of the AP in a safe place before it is installed in a hard-to-reach
location. The MAC address of the AP is printed on a label at the bottom of the
product.
The steps to install the AP with no configuration (zero-configuration) are as
follows:
- Ceiling Mount the Access Point or Wall Mount the Access Point
- Connect the Access Point to the Network
- Power the Access Point On
Ceiling Mount the Access Point
Mounting the access point (AP) on the ceiling consists of the following steps:
- Affix the bracket to the T -grid: Use the mounting bracket to install the AP on the ceiling. Fix the bracket to the T-grid and rotate the bracket so that it snaps on the T-grid. The bracket is now parallel to an arm of the T-grid. Ensure that the bracket is properly snapped to the T-grid, as shown below.
- Mounting the AP on the bracket: Place the first mounting post on the rear-side of the AP on to the lower notch of the bracket. Rotate the AP such that the center mounting post fits in to the center notch on the bracket. Ensure that all the mounting posts on the rear-side of the AP are snapped in to the respective notches on the bracket. The mounting posts now properly fit in the respective notches of the bracket and the AP is mounted properly.
Mounting Instructions using the Silhouette/Interlude Bracket Mount: The
Silhouette/Interlude mounting bracket is not a part of the standard package
and must be procured separately. The mounting instructions for the
Silhouette/Interlude Bracket Mount are similar to the Standard Package
Content’s mounting instructions.
Note: As a best practice, label the APs using MAC addresses or your own
convention. For example, use serial numbers, so that you can easily identify
the APs.
Wall Mount the Access Point
Note: The wall mounting accessory SKU (MNT-AP-FLAT-14CM) can be ordered
and purchased separately.
For instructions on wall mounting the access point, refer to Wall Mount the
Access Point article.
Connect the Access Point to the Network
To connect the access point (AP) to the network, perform the following steps:
- Ensure that a DHCP server is available on the network to enable network configuration of the AP.
- Add the DNS entry WiFi-security-server on all DNS servers. This entry must point to the IP address of the server.
- Ensure that DHCP is running on the subnet to which the AP is connected.
- Check the LEDs on the AP to ensure that it is connected to the server.
- Log on to the server using sash and run the get sensor list command.
You will see a list of all Arista devices that are recognized by the server. Single Sign-On users can go to the Monitor tab in Cloud Vision WiFi and check whether the device is visible under the Monitor tab.
The AP is connected and operational.
Note: If zero configuration fails, the AP must be configured manually.
Important: If DHCP is not enabled on a subnet, the AP cannot connect to that
subnet with zero-configuration. If the DNS entry is not present on the DNS
servers, or if you do not have the DHCP server running on the subnet, you must
manually configure the AP. For details on configuring an AP manually, see the
Access Point Configuration guide on our website at
https://www.arista.com/en/support/product-documentation .
Connect the Access Point using PoE
If you are using a PoE injector, make sure the data connection is plugged
into a suitable switch port with proper network connectivity.
For PoE port details, see the Rear Panel section.
Power the Access Point On
You can power the access point (AP) on by plugging one end of the Ethernet
cable into the PoE switch or injector and the other end into the Ethernet/PoE
port on the AP. Ensure the PoE source you are using is turned on.
As an alternative to PoE, you can insert a compatible power adaptor plug into
an AC power outlet and the other end into the power input port on the AP.
Note: If you are not using PoE, ensure that you use only an AC power
adaptor supported by the AP.
Using the Access Point with Power Adapter
Use a compatible power adaptor (Arista SKU: PWR-AP-W4) to power the AP.
Warning: The C-330 AP is intended to be supplied with UL-listed PoE power
source suitable for use at 40ºC, and whose output meets LPS requirements or
PS2, with a rating of 48V DC (0.5A minimum).
If you are not using PoE+, ensure that you use only an AC power adaptor
supported by the AP . This product is intended to be supplied by a Listed
Direct Plug-In Power Unit marked “Class 2”, Listed Power Adapter or DC power
source marked “L.P.S.” (or “Limited Power Source”) and rated from 12 V DC,
2.5A minimum.
To power up the device with power adapter, perform the following steps:
- Plug the power cable into the DC power receptacle at the rear of the AP.
- Plug the other end of the power cable into an 110V~240V 50/60 Hz AC power source.
- Wait until the AP is ready. Refer to the LED status table.
Access Point Troubleshooting
The table below lists some of the troubleshooting guidelines for the access point (AP).
Problem | Solution |
---|---|
The AP did not receive a valid IP address via the DHCP. | Ensure that the DHCP |
server is on and
available on the VLAN/subnet to which the AP is connected. If the AP still
fails to get a valid IP address, you can reboot it to see if the problem is
resolved.
Unable to connect to the server.| Ensure that the server is running and is
reachable from the network to which the AP is connected. If a firewall or a
router has Access Control Lists (ACLs) enabled between the AP and the server,
ensure that traffic on UDP port 3851 is allowed.
Use the IP-based server discovery method and ensure that you have correctly
entered the DNS name, wifi-security-server , on the DNS server.
Ensure that the DNS server IP addresses are either correctly configured, or
are provided by the DHCP server.
The AP might fail to authenticate with the server. In this case, an
‘Authentication failed ‘ event is raised on the server. Refer to the event for
recommended action.
The AP has encountered a problem.| If you are using Arista Cloud Services,
then open the TCP port 443 (SSL). If you have an on-premises installation,
then open UDP port 3851 and port 80.
If you are using a Proxy, Web Accelerator, or URL Content Filter between the
AP and the Internet, ensure that the settings allow communication between the
AP and Arista Cloud Services.
If your configuration requires you to specify an exact IP address or IP range
for Arista Cloud Services, please contact
supportwifi@arista.com.
Appendix A: AP-Server Mutual Authentication
The AP-server communication begins with a mutual authentication step in which
the AP and server authenticate each other using a shared secret. The AP-server
communication takes place only if this authentication succeeds.
After the authentication succeeds, a session key is generated. From this point
on, all communication between the AP and server is encrypted using the session
key.
The AP and server are shipped with the same default value of the shared
secret. Both the server and the AP have CLI commands to change the shared
secret.
Note: After the shared secret (communication key) is changed on the
server, all APs connected to the server will automatically be set up to use
the new communication key. You must manually configure the new communication
key on an AP if it is not connected to the server when the key is changed on
the server.
Note : Although the server is backward compatible—that is, older version
APs can connect to a newer version server—this is not recommended.
