I want to monitor the amount of collisions and errors I receive on interfaces but I can't find the correct OID can someone help me with this please

What device is this, and what version of IOS is it running?

does it really matter ? Are the OID's not a standard.

It's a cisco 4506 with IOS 12.2(20)

When it comes to MIB support, it does matter. Different devices and different software versions support different MIBs. For this switch, you can use the ETHERLIKE-MIB to get this information. For collisions, look at dot3StatsSingleCollisionFrames, dot3StatsMultipleCollisionFrames, dot3StatsLateCollisions, and dot3StatsExcessiveCollisions. For errors, you have ifInErrors and ifOutErrors from the IF-MIB as well as ethernet-specific errors such as dot3StatsAlignmentErrors, dot3StatsFCSErrors, dot3StatsSQETestErrors, dot3StatsInternalMacTransmitErrors, dot3StatsCarrierSenseErrors, dot3StatsInternalMacReceiveErrors, and dot3StatsSymbolErrors.


The total error count you see in the show interface output will be summed up in ifInErrors and ifOutErrors, but you can drill into the ethernet-specific counters to get a better idea of what is going on.
