Version 7.6.1.0 Introduced on the C-Series.
Usage
Information
Use this command to check various flags associated with each MAC address in the CAM.
The Example below 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 in the next two Examples. “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.
