Configuring the Maximum Number of MAC Addresses an Ethernet Port or a Port
Group Can Learn
To prevent a MAC address table from getting so large that it may degrade forwarding performance, you
may restrict the number of MAC addresses that can be learned. One approach is to do this on a per-port
or port group basis.
Follow these steps to configure the maximum number of MAC addresses that an Ethernet port or port
group can learn:
To do… Use the command… Remarks
