Usage Guidelines

After MAC address learning limit rules are successfully configured, you can run the display mac-limit command to view the configuration.

If the device is configured with a large number of MAC address learning limit rules, you are advised to specify parameters in the display mac-limit command; otherwise, excessive output information may cause the following problems:

The output information is repeatedly refreshed, and thus required information cannot be obtained.
The system fails to respond to other requests because it is busy searching information.

When running the display mac-limit command, note the following points:

If no optional parameter is specified, all MAC address learning limit rules are displayed.
If interface-type interface-number is specified in the command, the MAC address learning limit rules of the specified interface are displayed.
