I have a 2821 router with HWIC-4T running 124-13d.bin
The problem is that i am able to bring up 2 ciruits on only port 0/0/1 and 0/0/3. If the same cabe is extended to port 0/0/0 or 0/0/2 it does not come up.
Configurations are exactly similar. I tried this with another 2821 and another HWIC-port and there it works only on port 0/0/1 & 2 but not on others. Are there any known problems with this module?
