1.2.3 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:

Use either command to
configure on a port or
ports in a group.
Configure the maximum
number of MAC addresses
that can be learned on an
Ethernet port or port group
or configure whether
frames with unknown
destination MAC
addresses can be
forwarded or not after the
upper limit is reached

Required
The maximum number of
MAC addresses that can
be learned on a port or
port group is not
configured by default.
