I recently installed a WIC 1DSU-T1-V2 card into a 1841 router to add to a multilink bundle. I inserted it in Slot 1 and powered up the router and there was a new serial interface showing in the config automatically as s0/1/0. I was able to get it setup with ppp multilink and added to the multilink group. The problem is I need to do a sh controller or sh service-module to see if there are errors happening (I'm using this card as a replacement for an interface that was giving errors with this line before). I can do a sh s0/1/0 and that works but I can't see deeper.
I found it odd that the serial port just appeared in the config when I booted without having to do anything but can someone tell me if this is correct behavior and how I see the Controller or CSU info for troubleshooting?
