1.2.5 Configuring 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:
