Chapter 1 Port Additional Characteristics Configuration Commands

Configuring Port Isolation

1.1.1 port-protected
Syntax
To configure a port isolation group, run the following command. To return to the default setting, use the no form of this command.
port-protected group-id [no] port-protected group-id
Parameters

Default Value
None
Usage Guidelines
The command can be used to configure the group isolation in global configuration mode.
Example
The following example shows how to set ID of the isolation group to 1. Switch_config#port-protected 1
1.1.2 Description
Syntax
To set the port isolation group description, run the following command. To delete the description, use the no form of this command.
description word no description
Parameters

characters at most.

Default Value
None
Usage Guidelines
The command can be used to describe the group in global configuration mode.
Example
The following example shows how to set ID of the isolation group g 1 to 1. Switch-config-p 1 #description g 1
1.1.3 switchport protected
Syntax
To set port isolation, run the following command. To return to the default setting, use the no form of this command.
switchport protected no switch port protected
Parameters

Default Value
None
Usage Guidelines
The command must be configured in layer-2 port configuration mode. The system configures isolation not based on groups by default and group-id doesn’t need to configure at the end. If configures isolation based on groups, it should be configured in global mode. Only deleting the isolation on all ports can you reselect isolation based
on groups or not based on groups.
Example
The following example shows how to set isolation of port g0/1 not based on groups.
Switch_config_g0/1 #switch port protected

Configuring the Storm Control Command

Parameters

control.
count| Defines the threshold flux of the storm. 1-65535

Default Value
The storm control function is disabled by default.
Usage Guidelines
The command must be configured in L2 port configuration mode.

The following example shows how to set the unknown unicast-frame storm to 20pps on port g0/1.
Switch_config#interface g0/1
Switch_config_g0/1 #storm-control unicast threshold 20

Configuring Switch port Rate Limit

Usage Guidelines
The command must be configured in physical interface configuration mode.
Example
The following example shows how to set interface g0/1 to the dynamic port security mode.
Switch_config#inter g0/1
1.6.2 switch port port-security dynamic
Syntax
To configure the maximum number of MAC addresses when the port is in dynamic security mode, run switchport port-security dynamic maximum. To return to the
default setting, use the no form of this command.
switch port port-security dynamic maximum dynamic_number [no] switch port port-security dynamic maximum
Parameters

Default Value

Configuring Port Binding

Syntax
To bind a MAC address to a
IP address, run switchport port-security bind]block {ip/arp]both-arp-ip ip- addr] ipv6 ipv6-addr] mac mac-addr }.
To cancel the address binding one by one or to exit the port binding state by cancelling all addresses on the port, run no switchport port-security bind]block {iplarp] both-arp-ip ip-addr I ipv6 ipv6-addr I mac mac-addr}.

Parameters

Default Value
None
Usage Guidelines
It works in layer-2 port configuration mode.
The port binding function is forbidden by default. However, if one address is bound, the port is then in binding state unless you use the negative form of this command to
clear all bound address items.
Example
The following example shows how to bind IP address 1.2.3.4 to MAC address
0001.0001.1111 on interface g0/1 to decline the IP packets and ARP packets from the bound address.
