[c-nsp] 2900 series switches loosing ports

[Cory Ayers]

Assuming the ports have failed before that last boot, I would think show
post should work.  I don't know what you would see prior to a reboot and
subsequent POST.

show post 
POST FAILED: FastEthernet0/9 failed front-end loopback test
POST FAILED: FastEthernet0/10 failed front-end loopback test
POST FAILED: FastEthernet0/11 failed front-end loopback test
POST FAILED: FastEthernet0/12 failed front-end loopback test
