Cisco - ISDN Debug Information 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 6: DEBUG ISDN Q921 ● Example 7: DEBUG ISDN EVENT, DEBUG ISDN Q931 ● Example 8: 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. http://www.cisco.com/warp/public/129/18.html (1 of 11) [5/6/2001 3:50:03 PM] Cisco - ISDN Debug Information 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' RX <- CALL_PROC dsl = 0 pd = 8 callref = 0x81 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.
