the static address table will be accepted, all other packets are dropped. Note
that the dynamic addresses stored in the address table when MAC address
learning is disabled are flushed from the system, and no dynamic addresses are

◆
The mac-learning commands cannot be used if 802.1X Port Authentication has
been globally enabled on the switch with the
dot1x system-auth-control
command, or if MAC Address Security has been enabled by the port security
command on the same interface.
Example
The following example disables MAC address learning for port 2.
Console(config)#interface ethernet 1/2
Console(config-if)#no mac-learning
Console(config-if)#
