Respond to the State attribute values as follows:

If the state of the interface in question is up, check the statistics

associated with that layer.

If the statistics show that the media is OK, go to Chapter 6.

If the state is not present, the dynamic loader did not load the driver

(lower-layer protocol) on the slot. Make sure the link or net module and

port are up. Then, make sure the driver runs on the slot in the

configuration of the router.

If the state is down, check the log to determine the reason, as follows:

Save the log.

Issue the

clearlog

command.

Use the Configuration Manager to set the Enable parameter to

Disable, or use the Technician Interface to set the Enable attribute

to 2.

Use the Configuration Manager to set the Enable parameter to

Enable, or use the Technician Interface to set the Enable attribute

to 1.

View the log.

If the state is not up, test the cable and the transceiver.

If the cable and transceiver are OK, use Packet Capture to test the

reception and transmission of data as it passes through the cable. See

Appendix B for instructions.

If a problem occurred after connecting a new cable, make sure it is the

proper cable for the application you are using.

See the Cable Guide for information.
