CRC Errors are reported under the RMON mib. An example OID is:
  1.3.6.1.2.1.16.1.1.1.5.x where x is the snmp interface number

The RMON mib also supports counters for collisions, fragments, drops,
jabber, over and under sized packets, etc. You will have to research
whether your particular router supports the RMON mib or not.

Also, MIB2 supports counters for interface errors inbound and outbound.
An example is:
 inbound = 1.3.6.1.2.1.2.2.1.14.x where x is the snmp interface number

This particular error counter includes many different errors (as well
as the CRC's), and some manufacturers will include collisions in this
value even though collisions are not officially an error.
