Usage
Information
Use this command to check various flags associated with each MAC address in the CAM.
The example above shows information for two MAC addresses. The second entry is for MAC
address 00:00:a0:00:00:00 (leading 0s are not shown), which is shown as learned on VLAN
ID 4094 (0xfff), as shown below in the example for
show mac-address-table and the
example for
show cam mac linecard. Above, “STATIC_BIT=0” means that the address is
dynamically learned.
When an entry is listed as STATIC_BIT=1, its HIT_SA is 0, which signifies that this
address is not getting continuously learned trough traffic. The HIT_DA is set when a new
learn happens, and after the first age sweep, it gets reset.
Example
(show
mac-address-table)
FTOS#show mac-address-table

4094 00:00:a0:00:00:00 Dynamic Gi 2/0 Active
