[cisco-voip] isdn bind-l3 ccm-manager

[Erick Bergquist]

Was the router maybe in fallback mode when you were making changes and maybe saved the new config? Did MGCP lose registration with CCM and/or the T1 PRIs bounce. Why do you h323 command under loopback if it is a MGCP gateway?

 Have seen this command vanish from config when T1 flapped, etc my self many times across several IOS versions. There are some bugs on it, but also may be due to way things are configured or what happened. 

Can you provide some more details on what the config was like before any changes?  Have any pots dial-peers with the PRI port under them and application/service mgcpapp on them?

Group,

    I was making a network change last night and had an odd result.  I had a 2821 with an MGCP PRI and 2 WIC cards with PtP T1s.  I took the WIC cards out and installed them in a 1760 to separate the WAN function from the VG functions.  After taking out the 2 WICs I applied the following changes to the 2821 VG....

As you can see I did not take out the "isdn bind-l3 ccm-manager" command from the ser0/2/0:23 interface.  The only thing that I can think may have done this was the Lo0 commands that I added for h323 binding.


Anyone have an answer as to why this would have happened and made for an uneasy change?

Steve
