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.
