Identifying a Port or a Module 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 Menu 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 could 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 Menu.
2. From the MAC Menu menu, type 8 to select Show port and module
number 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
the Enter key:
XXXXXX XXXXXX
The following prompt is displayed:
Please enter VLAN ID -> [1 to 2048]:
4. Enter the VLAN ID. If no VLAN ID is entered, the default value of “1' will
be taken.
The management software displays a prompt containing the port,
VLAN Name, and the module 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.
