Halo CIscoer, help me on this ISDN debug:

12:24:38: CALL_PROC pd = 8 callref = 0xF5

12:24:163208757248: ISDN BR1/4: TX -> RRr sapi = 0 tei = 64 nr = 2

12:24:45: ISDN BR1/4: RX <- INFOc sapi = 0 tei = 64 ns = 2 nr = 1 i = 0x080

1F54508028090

12:24:45: DISCONNECT pd = 8 callref = 0xF5

12:24:45: Cause i = 0x8090 - Normal call clearing

12:24:193273528320: ISDN BR1/4: TX -> RRr sapi = 0 tei = 64 nr = 3

12:24:193273528320: BRI1/4: wait for isdn carrier timeout, call id=0x817F

12:24:195440255788: DDR: Dialing failed, 5 packets unqueued and discarded

12:24:195440239956: ISDN BR1/4: TX -> INFOc sapi = 0 tei = 64 ns = 1 nr = 3

i = 0x0801754D08028090

12:24:193273528320: RELEASE pd = 8 callref = 0x75

12:24:195440240252: Cause i = 0x8090 - Normal call clearing

12:24:45: ISDN BR1/4: RX <- RRr sapi = 0 tei = 64 nr = 2

12:24:45: ISDN BR1/4: RX <- INFOc sapi = 0 tei = 64 ns = 3 nr = 2 i = 0x080

1F55A08028090

12:24:45: RELEASE_COMP pd = 8 callref = 0xF5

12:24:45: Cause i = 0x8090 - Normal call clearing

12:24:195440239868: ISDN BR1/4: TX -> RRr sapi = 0 tei

Thank YOu

Cause i = 0x8090 - Normal call clearing ....80 means the cause code originator is the router itself.

90 means the call is most likely failing at a higher layer protocol such as PPP, authentication or idle timeout related issues. will need to verify the router configuration.

deb isdn q931 / deb ppp nego at both the end routers will be helpful + the show run on both.

Thanks, Mak.

Please check this configuration, just wanna know: do I have to set a command at the physical interface with "ppp authentication chap"?

Thank YOu,

HATO

yes..You do need to have "ppp authentication chap" under the physical interface..With that command, config looks ok..So need to see the following debug as pointed by makchitale..

debug isdn q931

debug ppp authentication

debug ppp negotiation

term mon

Thanks...Tejal

The configs shown here do not seem to be for a matching pair (central & remote)...the dialer ip address do not match the dialer map next hop ip address commands.....Please collect the debugs on both the sides with msec timestamps.

Thanks, Mak.

1.When I try config using Config Maker...... the remote site do not have these command:

-dialer map snapshot 1 name 010_RO_01 broadcast xxxxxxxxxxx

-snapshot client 15 360 suppress-statechange-update dialer

and the "backup delay 1 1".

2.When I do a shutdown on the serial0/0 at central site. Debug only show that bri1/3 and bri1/4 make a call.

3.Why the remote router do not make a dial first.

Thank You

HATO
