rptrMonitorPortFCSErrors

Module: RFC1516-MIB

OID (symbolic): RFC1516-MIB::rptrMonitorPortFCSErrors

OID (numeric): 1.3.6.1.2.1.22.2.3.1.1.5

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: This counter is incremented by one for each frame received on this port with the FCSError signal asserted and the FramingError and CollisionEvent signals deasserted and whose OctetCount is greater than or equal to minFrameSize and less than or equal to maxFrameSize (Ref: 4.4.2.1, IEEE 802.3 Std).

The approximate minimum time for rollover of this counter is 80 hours.

What is rptrMonitorPortFCSErrors?

Count of frames received on this port with a bad FCS/CRC checksum (but otherwise valid framing, no collision), with a minimum rollover time of about 80 hours. A rising count on one specific port, while others stay clean, usually points to a bad cable or NIC on that segment rather than a hub-wide issue.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.22.2.3.1.1.5
snmpwalk -v2c -c public <target> RFC1516-MIB::rptrMonitorPortFCSErrors

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.22.2.3.1.1.5.1
snmpget -v2c -c public <target> RFC1516-MIB::rptrMonitorPortFCSErrors.1
