I am having a problem getting the ports to go up up on my 16 port etherswitch module on a 2621xm.
The EtherModule directly connects to a C3548-XL Switch.
EDIT: Found what I was doing wrong, and thought I might as well keep this here to help others.
I changed the cable from a straight through to a cross-over, and it worked.
Yes, I forgot the basics...went too deep into it. Lesson for all to remember. Do not get too comfy with the switches doing auto crossover for you!
Let my idiocy help others. :)
