Description: Return this port group's total CRC errors.
What is rptrPortGrpPktStatsCRC?
This read-only Counter32 is a running tally of the total number of CRC (checksum) errors on this port group (board) since the counter was last reset (it wraps back to zero on overflow, standard SNMP counter behavior). An admin polls rptrPortGrpPktStatsCRC periodically to flag frames arriving corrupted, often from electrical noise, a marginal cable run, or a failing transceiver. For example, if rptrPortGrpPktStatsCRC keeps climbing while the link stays up, that's the cue to check this port group's cabling, NIC, or duplex settings before the problem shows up as user-visible slowdowns.
