I am having som Slip Secs errors and Errored Secs show up on one of my controllers and was wondering how to stop them. The ISP says nothing is wrong on their end and they see no errors in the mux. Here is the out come from sh controllers T1 0/0/1


T1 0/0/1 is up.
Applique type is Channelized T1

They are all configured the same. The only one throwing errors is controller 0/0/1 and interface s0/0/1:1

on the mukltilink...the interface itself des not seem to be flapping (0 resets)...I am not sure...

try this to get your clocking right:
network-clock-participate wic 0
network-clock-participate wic 1
network-clock-select 1 T1 0/0/1

This should do it.

 
Doing that made my other controllers start getting errors.

My ISP said that each T1 should have its own clocking.
 
Finally figured this one out. The ISP was looking for individual clocking on each T1. So the clocking has to be configured for independent clocking.

controller t1 0/0/0
clock source line independent
channel-group 1 timeslots 1-24

I had to do this on each controller and now everything is ok. Thanks for the replies.
