Section I: Basic Operations

or assigned to the ports on the switch and stored in the switch’s MAC
address table.

Figure 14 is an example of the information displayed by this command for
unicast addresses.

Figure 14. SHOW SWITCH FDB Command - Unicast Addresses

Note

The first address in the unicast MAC address table is the address of
the switch.

The columns are defined here:

ˆ

VLAN ID - The ID number of the VLAN where the port is an untagged
member.

ˆ

MAC - The dynamic or static unicast MAC address learned on or
assigned to the port.

ˆ

Port - The port where the address was learned or assigned. The MAC
address with port 0 is the address of the switch.

ˆ

Status - The type of address: static or dynamic.

Figure 15 is an example of a multicast address.
