cntPhyState

Module: MELLANOX-EFM-MIB

OID (symbolic): MELLANOX-EFM-MIB::cntPhyState

OID (numeric): 1.3.6.1.4.1.33049.2.2.1.2.1.1.4

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-only

Description: Physical state of this port

What is cntPhyState?

Read-only OCTET STRING giving the physical link state of this external IB port (e.g. link up/down/polling). Admins check this before cntLogState when a port isn't passing traffic, since a physical-layer problem must be resolved first.

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-EFM-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-EFM-MIB::cntPhyState.1

SNMPv3 example:

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