Usage Guidelines

Usage Scenario

The MUX VLAN function isolates Layer 2 traffic between interfaces in a VLAN. A MUX MAC address entry is learned by a MUX VLAN enabled interface. The learned MUX MAC address entries are deleted after the switch restarts.

After configuring the MUX VLAN function, you can run the display mac-address mux command to check whether the learned MUX MAC address entries are correct.

Follow-up Procedure

If the displayed MUX MAC address entries are invalid, run the undo mac-address command to delete MUX MAC address entries.

Precautions

If you run the display mac-address mux command without parameters, all MUX MAC address entries are displayed.

If the MAC address table does not contain any MUX MAC address entry, no information is displayed.

When the switch has a large number of MUX MAC address entries, it is recommended that you specify parameters in the command to filter the output information. Otherwise, the following problems may occur due to excessive output information:

The displayed information is repeatedly refreshed, so you cannot find the required information.
The system traverses and retrieves information for a long time, and does not respond to any request.
