I have a 3845 that has increasing input errors, CRC and overrun on its g0/0 interface. The 3845 is connected to a WS-C3750G-48PS. The 3845's g0/0 is connected to the 3750's g2/0/1. However, 3750's g2/0/1 has no input errors, CRC, or overrun. Could this be an IOS bug?
Troubleshooting steps:
1. restarted 3845 (still increasing)
2. replaced cable between 3845 and 3750 (still increasing)
3. moved connection from 3750's g2/0/1 to a new switchport (g2/0/7) - there were 0's across the board, but after a couple of hours, input errors, CRC, and overrun started to accrue again.
