Displaying the MAC Address Table
To display the MAC address table, use the following command.
• Display the contents of the MAC address table.
EXEC Privilege mode
show mac-address-table [address | aging-time [vlan
vlan-id
]| count | dynamic
| interface | static | vlan]
–
address
: displays the specified entry.
–
aging-time
: displays the configured aging-time.
–
count
: displays the number of dynamic and static entries for all VLANs, and the total number of
entries.
–
dynamic
: displays only dynamic entries.
–
interface
: displays only entries for the specified interface.
–

MAC Learning Limit
MAC address learning limit is a method of port security on Layer 2 port-channel and physical interfaces,
and VLANs. It allows you to set an upper limit on the number of MAC addresses that learned on an
interface/VLAN. After the limit is reached, the system drops all traffic from a device with an unlearned
MAC address.
