ethernetPortStatsCarrierSenseErrors

Module: ACMIB

OID (symbolic): ACMIB::ethernetPortStatsCarrierSenseErrors

OID (numeric): 1.3.6.1.4.1.1751.2.18.10.7.1.12

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The number of times that the carrier sense condition was lost or never asserted when attempting to transmit a frame on a particular interface.

The count represented by an instance of this object is incremented at most once per transmission attempt, even if the carrier sense condition fluctuates during a transmission attempt.

What is ethernetPortStatsCarrierSenseErrors?

This counter shows how many times the network interface failed to sense the carrier signal when trying to transmit, indicating the medium appears to be in use when it shouldn't be. Engineers investigate this to detect cabling problems, transceiver faults, or phantom signals that fool the interface into thinking the line is busy. A value climbing above 10 errors per minute means the port is having trouble with the physical layer handshake.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.10.7.1.12
snmpwalk -v2c -c public <target> ACMIB::ethernetPortStatsCarrierSenseErrors

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.10.7.1.12.1
snmpget -v2c -c public <target> ACMIB::ethernetPortStatsCarrierSenseErrors.1
