Hello Everyone,
Wondering if anyone else has ran into this before. I have a 2821 router with (3) VWIC2-2MFT-T1/E1 cards. I have (2) data T1s on card 0 and (3) PRIs spread accross cards 1 and 2. The two data T1s are bonded into a multilink interface and are both from the same provider. All interfaces are set to 'clock source line' and my network clocking looks like this:
network-clock-participate wic 0
network-clock-participate wic 1
network-clock-participate wic 2
network-clock-select 1 T1 0/1/0
network-clock-select 2 T1 0/2/0
So my problem is that the data T1s are taking many input and CRC errors whilst the controllers are taking many slips. Of course, I believe this is a clocking problem. My PRIs are running clean. So to put the two data T1s on their own clocking domain, I enter the command:
no network-clock-participate wic 0
This causes the WAN connection to go down. If I put 'network-clock-participate wic 0' back in the WAN still stays down. I have to reload the router to get it back up. It's a remote site so I can't do much troubleshooting while it's down. I had a user at that site run a few commands for me and I see that while the WAN is down, both controllers are up and both serial interfaces are up/down.
I have at least 20 other remote sites that I'm able to have this sort of configuration at so I'm wondering what the problem may be. I don't think it seems like a hardware issue, but it may be. I have been working with TAC for the past week but they've been of little help so far.
Thanks for any input,
Jake
