Which Cisco command is used to display the MAC address table on a Catalyst 2900 switch?
- Show mac-address-table
- Show running-configuration
- Show port-map
- Show ports
- Show interface
A. Show mac-address-table
The show mac-address-table command is used to display MAC address table for the Catalyst 2900 switch.
The complete command syntax for the command is:
show mac-address-table [static | dynamic | secure | self | aging-time | count] [address hw-addr] [interface interface] [atm slot/port] [vlan vlan-id]
The following is the sample output of the show mac-address-table command:
Dynamic Addresses Count: 4
Secure Addresses (User-defined) Count: 0
Static Addresses (User-defined) Count: 0
System Self Addresses Count: 46
Total MAC addresses: 50
Non-static Address Table:
Destination Address Address Type VLAN Destination Port
------------------- ------------ ---- --------------------
0010.0de0.e456 Dynamic 1 FastEthernet0/1
0010.6b00.2345 Dynamic 2 FastEthernet0/7
0010.4b00.1235 Dynamic 2 FastEthernet0/6
0060.3cf4.1123 Dynamic 1 FastEthernet0/2
All other options are incorrect as they do not display the address table for the Catalyst 2900 switch.
The show mac-table and show port-map commands are invalid.
