Are you using a workaround to prevent the symptoms from occurring? If

so, what?

Consideration of the workaround you are using may help you to isolate the

problem.

Which end stations are involved?

Identifying the end stations involved can help you to determine the scope of

the problem.

Research and consider the following additional causes:

• Traffic congestion

Examine the MIB statistics and the event log to check for traffic

congestion. If you determine that traffic congestion is the problem,

consider redistributing traffic to relieve congestion.

• A software anomaly

Check the following documents for solutions to your problem:

-- Release Notes for Router Software Version 12.00

-- Release Notes for Site Manager Software Version 6.00

Look at the LEDs on the router’s front and rear panels, and refer to the

event log and MIB statistics to answer the following questions:

Are the symptoms limited to:

• A single protocol on a single port?

If so, the problem is most likely in the network layer or above. See

Chapter 6.

• Multiple protocols on a single port?

If so, the problem is most likely in the physical or data link layer. See

Chapters 4 and 5.

• A single protocol on multiple ports in one slot?

If so, the problem is most likely in the configuration of the network layer

protocol. See Chapter 6.

• Multiple protocols on multiple ports in one slot?

If so, and if the same protocols are running successfully in other slots, the

problem is most likely physical. See Chapter 4.
