We are seeing input errors on all the interfaces that connect to our F5's.

We have checked the duplex (hard set to 100 full both ends, swapped the cable and switch interface but not changed the F5 as all the interfaces have the same issue on different F5's and Cisco switches.

The switch is WS-C3750-24TS code 12.2(25r)SEC
