sfpBias
Module: PICA-PRIVATE-MIB
OID (symbolic): PICA-PRIVATE-MIB::sfpBias
OID (numeric): 1.3.6.1.4.1.35098.1.8.1.6
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The bias current of sfp ransceiver transfer.
What is sfpBias?
sfpBias reports the laser bias current of the SFP transceiver plugged into the port identified by sfpIndex. Admins monitor bias current because a steadily rising value over the optic's lifetime typically signals laser aging and predicts eventual transceiver failure. For example, a transceiver whose sfpBias has crept up toward its rated maximum over several months would be flagged for proactive replacement before it fails outright.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.35098.1.8.1.6 snmpwalk -v2c -c public <target> PICA-PRIVATE-MIB::sfpBias
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.35098.1.8.1.6.1 snmpget -v2c -c public <target> PICA-PRIVATE-MIB::sfpBias.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> sfpBias.1
