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?
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.
