Switch Port MAC Addresses
The MAC address assigned to each switch port is used internally by such
features as Flow Control and the Spanning Tree Protocol. Determining the
MAC address assignments for individual ports can sometimes be useful when
diagnosing switch operation. To display these addresses, use the walkmib
command at the command prompt
1. From the Main Menu, select 5. Diagnostics and from the Diagnostics menu,
select 4. Command Prompt
2. If multiple VLANs are configured, use the Space bar to select a VLAN.
N o t e This procedure displays the MAC addresses for all ports and existing VLANs
in the switch, regardless of which VLAN you select.
3. Type the following command to display the MAC address for each port on
the switch: walkmib ifPhysAddress
The following figure is an example of the display:
