Example

# 11: mm/dd/yy 03:15:49.517 INFO SLOT 1 SWSERV Code: 136

ISDN Configured for switch type BRI NI1.

Look at the attribute values of the following MIB objects:

• wfIsdnSwitchCfgEntry

• wfPppCircuitEntry

• wfSwservOptsEntry

• wfPppLineEntry

• wfIsdnBriInterfaceEntry

• wfPppWhoamiEntry

• wfSwservOutPhoneNumEntry

• wfIsdnLocalPhoneNumEntry

• wfIsdnPoolEntry

• wfIsdnCallInfoEntry

If a call fails, do the following:

Verify that a line in a pool is available to make a call.

Verify that a call setup is in the log and that the calling and called

numbers are correct.

If the ISDN connection is present, filter the PPP event messages to verify

that the PPP negotiation succeeded.

The Technician Interface command is as follows:

log -fftwid -ePPP

Verify that the CHAP or PAP data in wfSwservOptsEntry matches that

of the remote router’s wfPppWhoamiEntry.

For CHAP, make sure that the secret is identical on both sides of the link.

Verify that the protocol network numbers and adjacent host information

are correct.

If using call screening on incoming calls, verify that the numbers in

Dialup

Incoming Phone Numbers match those in the Call Setup

messages received.
