I have tried researching this but have not found any substance on this type
of error. I have an ASR9000 with a Layer3 Bundle-Eth connected to a VPC
Nexus5596. Both sides run LACP active/active. The ports are connected via
10G XFP 10G-SR and 10G SFP+ 10G-SR (OM3 Fiber)
One of the Bundle members appears to be accruing active Input MIB CRC which
then reflects on standard Input CRC errors. These accruing errors do not
seem to be service impacting as there is 500M-1G of traffic on the physical
member 24/7 with sensitive applications such as Voice. The other member in
the bundle does not appear to exhibit this issue.
Input error CRC = 2635490
Input MIB CRC = 2635490
The Nexus 5k side just indicates accruing "Output Errors" under the
interface with no further details. The actual counter error output of the
interface sees nothing.
