Is it Possible for you to test the circuit with another WIC card?

Hello,

I do had the same problem, and I put clock source internal under e1 controller and Slip Secs error had gone. I have 6 E1 interfaces bundled as multilink and one of the interface kept getting error which was caused time out after some number of replies when I tried ping remote sites.

I just wanna ask if I have got sever E1 controller, do I need to put network-clock-participate wic X

network-clock-select 5 E1 X/0 for each slots?

thanks a lot in advance

first of all, if the port are connected to telco circuits, you must configure clock source line on them all.

Then, you have to configure network-clock-participate for all the WIC involved, and network-clock-select with different priorities for all the circuits.

In reality the latter command is need only icase one or more circuits go down.

It`s strange, but I configure clock source to be internal on two E1 (clock source of other 4 E1 forming multilink are line) which are connected to telco circuirs and all Slip Secs error disappeared. I did not configure network-clock-participate at ala on my router. I wonder if it is one of the solution to get rid of slip sec error? Could you explain more about using network-clock-participate and network-clock-select command if possible? thank a lot

Hello, the commands are needed to form a reliable clock source. Without them, you can have unpredictable results.
