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

configured demand circuit comes up and the associated events appear in

the log.

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

services running on the slots in question.

The Technician Interface command is as follows:

log -fftwid -eSWSERV -s

<slot_no.>

Example

If you are filtering events from slots 3 and 4, enter the following command:

log -fftwid -eSWSERV -s3 -s4

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

Filter the log to display the network layer protocol event messages and

determine whether they are activating.

Use the Technician Interface

get

Quick Get tool to examine the following MIB objects for configuration

settings and errors:

• wfPppCircuitEntry

• wfPppLineEntry

• wfPPPWhoamiEntry

• wfSwservOptsEntry

• wfSwservOutPhoneNumEntry

• wfModemIfEntry

If you are running IP with RIP or OSPF for dial backup, do the

following:

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
