Cisco 7304 Routers

Following is an example of the show interfaces command for Cisco 7304 routers. In this example, the

serial interfaces (0 to 5) are on a 6E3 line card in slot 1, also, the status information for interfaces 1

through 5 is omitted. (Interfaces are administratively shut down until you enable them.)

E3 Alarm and Event Detection

This section assumes that you are familiar with E3 alarms and line states. The 6E3 line card does not

have an LED for alarm and event detection. However, you can enter the show controllers serial slot/port

EXEC command to verify whether the alarm and event detection messages are active or inactive. Most

alarm and event detection messages are short-lived, because if problems occur, the line card clears the

error condition, but records the event to verify line card operation status.

The output from the show controllers serial slot/port EXEC command sends messages about the

following types of alarms and events:

• AIS (Alarm Indication Signal)

• LOF (Loss of Frame)

• LOS (Loss of Signal)

• RAI (Remote Alarm Indication)

• OOF (Out of Frame)
