ISDN Debug Information

This tech tip contains some common ISDN/PPP/CHAP debug messages, what they indicate, and suggestions for resolving them Check out the following examples:

● Example 1: DEBUG ISDN EVENT

● Example 2: DEBUG ISDN Q931

● Example 3: DEBUG DIALER

● Example 4: DEBUG PPP CHAP, DEBUG PPP NEGOTIATION

● Example 5: DEBUG ISDN EVENT, DEBUG ISDN Q931

● Example 7: DEBUG ISDN EVENT, DEBUG ISDN Q931

● Example 9: DEBUG PPP NEGOTIATION, DEBUG PPP CHAP

● Related Information

Example 1

Debug: DEBUG ISDN EVENT

BRI0: ISDN Event: incoming ces value = 1

BRI0: received HOST_TERM_REGISTER_NACK - invalid EID/SPID or TEI not

assigned

Cause i = 0x8082 - No route to specified network

Indication:

Usually a SPID problem To verify that TEI is assigned, try show isdn status Layer 2 information will tell if TEI is

assigned

Suggestions:

1 Check the configuration to see if the SPIDs are configured correctly

2 Have your service provider verify the SPIDs, and if necessary have them track the SPIDs

Trang 2

Example 2

Debug: DEBUG ISDN Q931

BRI0: Dialing cause: BRI0: ip PERMIT

BRI0: Attempting to dial 6968900

TX -> SETUP dsl = 0 pd = 8 callref = 0x01

Bearer Capability i = 0x8890218F

Channel ID i = 0x83

Called Party Number i = 0x80, '6968900'

Channel ID i = 0x89

RX <- PROGRESS dsl = 0 pd = 8 callref = 0x81

Progress Ind i = 0xC48A - Delay in response at called interface Signal i = 0x01

RX <- DISCONNECT dsl = 0 pd = 8 callref = 0x81

Cause i = 0x8295 - Call rejected

Signal i = 0x01

TX -> RELEASE dsl = 0 pd = 8 callref = 0x01

RX <- RELEASE_COMP dsl = 0 pd = 8 callref = 0x81

Signal i = 0x3F

Indication:

Remote router does not answer call

Suggestions:

Verify the telephone number and SPIDs

Example 3

Debug: DEBUG DIALER

BRI0: No dialer string defined Dialing cannot occur

Trang 3

Indication:

Dialing cannot occur

Suggestions:

Check the configuration (dialer map, dialer string, dialer group)

Example 4

Debug: DEBUG PPP CHAP, DEBUG PPP NEGOTIATION

command for name keyword and the correct hostname

Suggestions:

Check the following:

● the correct configuration of SPIDs,

● verify the SPIDs with the telco,

● if neccessary, have the telco track the SPIDs

Suggestion:

Use IOS 10.3(9), 11.0(5), 11.(1) or later These versions support a new feature for ppp authentication:

● ppp authentication chap callin

or

● ppp authentication pap callin
