Troubleshooting Routers

6-24

For a successful connection, the control protocol on both sides of the

conﬁgured demand circuits comes up, and the associated events appear in

the log.

3. Filter the log to display messages of all severity levels for the switched

access services running on the slots in question.

The Technician Interface command is

log -fftwid -eSWSERV -s

<slot_no.>

Example

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

log -fftwid -eSWSERV -s3 -s4

Determine whether the circuit is in slave mode or master mode.

5. Filter the log to display the network-layer protocol event messages and

determine whether or not they are coming up.

6. Use the Technician Interface get command or the Statistics Manager

Quick Get tool to examine the following MIB objects for conﬁguration

settings and errors:

— wfPppCircuitEntry

— wfPppLine Entry

— wfPPPWhoamiEntry

— wfSwservOptsEntry

— wfSwservOutPhoneNumEntry

— wfModemIfEntry

7. If you are running IP, and RIP or OSPF, for dial backup, do the

following:

a. Ping across the connection from the primary line.

If the ping fails, and the router fails to establish a backup connection,

issue the Technician Interface

show ip arp script command. Determine

whether you statically conﬁgured the ARP cache. If you are running

Frame Relay on the primary line, conﬁgure an IP adjacent host.

b. Check the slave site’s routing table for the routes it learned from the

master site. Do the same when the backup line comes up.
