cmEthernetAccPortThresholdVarOptVariance

Module: CM-PERFORMANCE-MIB

OID (symbolic): CM-PERFORMANCE-MIB::cmEthernetAccPortThresholdVarOptVariance

OID (numeric): 1.3.6.1.4.1.2544.1.12.5.1.4.1.2

Node type: OBJECT-TYPE

Type: Integer32

Access: read-write

Description: Variance in the Optical Power Transmitted (in dbM), beyond which threshold crossing alert will be generated.

What is cmEthernetAccPortThresholdVarOptVariance?

This read-write Integer32 sets the allowed variance in Optical Power Transmitted (in dBm) beyond which a threshold-crossing alert is generated, exactly as the MIB describes. An admin uses it to catch a fiber transceiver drifting away from its own baseline before the link fails outright, rather than only alarming on an absolute floor. Setting cmEthernetAccPortThresholdVarOptVariance to 3 dB on access port 44 means that transceiver's optical power has to wander that far from its established baseline before the operator gets paged.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2544.1.12.5.1.4.1.2
snmpwalk -v2c -c public <target> CM-PERFORMANCE-MIB::cmEthernetAccPortThresholdVarOptVariance

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2544.1.12.5.1.4.1.2.1
snmpget -v2c -c public <target> CM-PERFORMANCE-MIB::cmEthernetAccPortThresholdVarOptVariance.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.2544.1.12.5.1.4.1.2.1 i <value>
