Setting the Port Name You can assign names to the ports on Ethernet and Fast Ethernet modules to facilitate switch administration. To assign a name to a port, perform this task in privileged mode: Step 1 Step 2 Task Assign a name to a port. Verify that the port name is configured. Command set port name mod_num/port_num [name_string] show port [mod_num[/port_num]] This example shows how to set the name for ports 1/1 and 1/2 and how to verify that the port names are configured correctly: Console> (enable) set port name 1/1 Router Connection Port 1/1 name set. 78-12647-02 Software Configuration Guide-Catalyst 4000 Family, Catalyst 2948G, Catalyst 2980G, Releases 6.3 and 6.4 4-3
