linkSpeed
Module: CMM3-MIB
OID (symbolic): CMM3-MIB::linkSpeed
OID (numeric): 1.3.6.1.4.1.161.19.3.4.4.1.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Network connectivity, 100BaseT or 10BaseT.
What is linkSpeed?
This read-only enumeration reports the detected link speed on a port as either hundredBaseT(1) or tenBaseT(0). It gives an admin a live view of what speed a connected device actually negotiated, which should be cross-checked against the corresponding portNConfig setting. If linkSpeed reports tenBaseT(0) on a port that was configured for 100 Mbit/s, that mismatch points to a cabling or negotiation problem on that link.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.161.19.3.4.4.1.1.3 snmpwalk -v2c -c public <target> CMM3-MIB::linkSpeed
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.161.19.3.4.4.1.1.3.1 snmpget -v2c -c public <target> CMM3-MIB::linkSpeed.1
