Troubleshooting Routers

6-16

Enter the following command to display the IP forwarding table:

get wfIpBaseRtEntry.7.*

The Technician Interface displays the table in the following format:

wfIpBaseRtEntry.wfIpBaseRouteNextHop.

<next_hop>

Identify the incorrect routes. If you take a snapshot of your network

periodically, as described in Chapter 1, comparing the data can help you to

identify the incorrect routes.

Use the Packet Capture utility or a network analyzer to trace routes through

the network to see what, if any, nodes are forwarding incorrect routing

information in the form of RIP or Link State packets.

6. Determine whether the link is operational and the communication is

bi-directional. You can do this by getting the MIB object wfOspfIfEntry.

The display shows the state of OSPF on the interface, the identity of the

DR and BDR on the segment, how many hello packets the interface

received and transmitted, and how many link state updates it received,

and received and transmitted.

Troubleshooting IPX

This section assumes that you have isolated a problem to IPX. If not, refer to

Chapter 2 to determine whether these instructions apply to your problem.

This section assumes that you have loaded the scripts. Refer to Using Technician

Interface Scripts for instructions.

Troubleshoot IPX as follows:

1. Use the Events Manager or the Technician Interface to ﬁlter the log to

display messages of all severity levels for IPX running on the slots in

question.

The Technician Interface command is

log -fftwid -eIPX -s

<slot_no.>

Example

If you are ﬁltering events from Slots 3 and 4, you enter

log -fftwid -eIPX -s3 -s4
