Usage
Information
Use this command to check various flags associated with each MAC address in the CAM.
Figure 21-1 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 Figure 21-2 and Figure 21-3. 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.
