Module: MELLANOX-MIB

Description: Physical state of this port

What is cntPhyState?

Physical-layer state of this InfiniBand port (link training/up/down at the electrical level). A port stuck out of the expected physical state usually points to a bad cable, transceiver, or seating issue rather than a configuration problem.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33049.2.2.1.2.1.1.4
snmpwalk -v2c -c public <target> MELLANOX-MIB::cntPhyState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.33049.2.2.1.2.1.1.4.1
snmpget -v2c -c public <target> MELLANOX-MIB::cntPhyState.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cntPhyState.1
