Usage Guidelines

Usage Scenario

The MAC address table needs to be updated constantly because the network topology always changes. You can use this command to view learned MAC addresses in real time.

Follow-up Procedure

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

Precautions

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

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

When the wireless access point has a large number of dynamic 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.

Example
