Usage Guidelines

The MAC address table space is limited on a device. If the number of MAC address entries reaches the upper limit, the device cannot learn new MAC address entries before some entries in the MAC address table are aged out. In this case, the device broadcasts packets from new users, wasting network resources. To solve the problem, you can run the undo mac-address bridge-domain command to manually delete unnecessary MAC address entries of a specified BD.

Example

# Delete MAC address entries of BD 20.
