Identifying a Port Number by MAC Address
In some situations, you might want to know which port a particular MAC
address was learned. You could display the MAC address table and scroll
through the list looking for the MAC address. But if the switch is part of a
large network, finding the address could prove difficult.
The procedure in this section offers an easier way. You can specify the
MAC address and let the management software automatically locate the
port on the switch where the device is connected.
1. From the Main Menu, type 6 to select MAC Address Table.
2. From the MAC Address Table menu, type 7 to select View the Port of
MAC Address.
The following prompt is displayed:
Please enter MAC address:
3. Enter the MAC address of the node in the following format and press
Return:
XXXXXX XXXXXX
The management software displays a prompt containing the port
number on the switch to which the node is connected, if the
address was learned dynamically, or to which the address was
assigned, for a static address.
