Access Management Configuration 301

■

In the same aggregation group, the port isolation feature on one unit is 
consistent.

■

If a port is removed from an aggregation group, its port isolation configuration 
will not change.

■

If a port of an aggregation group is isolated on unit 1, then you can achieve 
port-to-port isolation between this aggregation group and all the ports of the 
isolation group on unit 1.

■

If all the ports on unit 1 of this aggregation group are removed from this 
aggregation group, then the isolation feature of this aggregation group is 
disabled, that is, the port-to-port isolation mentioned above is unavailable.

You can use the following command to set Layer 2 isolation on a port so as to prevent 
the packets from being forwarded on Layer 2 between the specified port and some 
other ports (group).

Perform the following configuration in Ethernet Port View.

By default, the isolation port pool is null and the packets are allowed to be forwarded 
between the specified port and all other ports on Layer 2.

You can enable the access management trap function using the following commands. 
When this function is enabled, the trap information of access management is 
delivered to the console for the purpose of monitoring. 

Perform the following configuration in System View.

By default, the access management trap is disabled.

After the above configuration, enter the 

 command in any view to display the 

current configurations of access management and port isolation information, and to 
verify the effect of the configuration.
