What is rlCdpInterfaceIllegalChksum?
This read-only Counter32 counts CDP packets received on an interface with an illegal (invalid) checksum. An admin monitors it to detect corrupted CDP frames, which can indicate cabling problems or a misbehaving neighbor. For example, a steadily climbing value here on one specific port would prompt an admin to inspect that cable or the attached device for a hardware fault.
