Configuring the MAC learning limit on ports

The device's forwarding performance can degrade as the MAC address table grows.
To prevent the MAC address table from getting so large that the forwarding performance degrades, limit
the number of MAC addresses that can a port can obtain.
To configure the MAC learning limit on a Layer 2 Ethernet interface or all ports in a port group:
Step...
1. Enter system view
2. Enter interface view
or port group view
