Within an FDDI station, the PHY and PMD entities make up a port. A port 
(consisting of the PHY/PMD pair that connects to the fiber media) is located 
at both ends of a physical connection and determines the characteristics of 
that connection. Each FDDI port is one of four types: A, B, M, or S. You can 
display port statistics and configure the following port parameters:

■

lerAlarm

■

lerCutoff

■

port labels

■

port paths

When you display FDDI port information, you receive information about 
ports, including the type, path, and port label, as well as other FDDI port 
statistics, such as error counters.

To view FDDI port information:

1 From the top level of the Administration Console, enter:

You are prompted for a port.

2 Enter the port about which you want to view information. Example:
