Controller t1 0/0/1 stays down even if PRI comes up
In one of my 2911's I have a VWIC3-4MFT-T1/E1 that terminates two pri circuit. s0/0/0:23 and s0/0/1:23 are in a trunk group. I've noticed that if the PRI flaps/bounces and comes back up, controller 0/0/1 and serial 0/0/1 stay down. Controller 0/0/0 and serial 0/0/0 always come back up. I have to restart the gateway everytime for 0/0/1 to come up. Thoughts? Interface config is below.
