Users Guide

NOTE: If you congure this command on an interface in a routed VLAN, and after the MAC addresses
learned reaches the limit set in the mac learning-limit command, IP protocols are aected. For
example, VRRP sets multiple VRRP Masters and OSPF may not come up.
When a channel member is added to a port-channel and there is not enough ACL CAM space, the MAC limit
functionality on that port-channel is undened. When this occurs, un-congure the existing conguration rst and
then reapply the limit with a lower value.
