Error bringing up MGCP Gateway

Unanswered Question
Sep 19th, 2007

I have a 2801 Router that gets the following error when I try to manually bring up mgcp:

Sep 19 20:36:04.753: ISDN Se0/1/0:23 **ERROR**: L2IF_SendPkt: idb is NULL

Sep 19 20:36:04.753: ISDN Se0/1/0:23 **ERROR**: L2IF_SendprimPkt: L2IF_SendPkt failed

Has anyone seen this before?

I have this problem too.

Hi Tom,

have you performed the Hard Loop Test to rule out hardware failure of the VWIC

Make sure no ACL are blocking MGCP traffic

and the following is configured.

interface serial0/1/0:23

isdn bind-l3 ccm-manager

I had not performed any loop tests (I have been lucky w/new hardware so that's generally the last thing I suspect). There are no alarms of any kind and the d-channel is up. The only difference in this site and my others is that the PRI is fractional (only 5 channels). I know 4.1(3) & MGCP do not 'support' this configuration and that may be the crux of my problem. I was expecting a different kind of error.

[+5]  to you.


I came across this issue and entering the isdn bind-l3 ccm-manager under serial interface resolved the issue.
