mlxIBPortGUID

Module: MELLANOX-MIB-4

OID (symbolic): MELLANOX-MIB-4::mlxIBPortGUID

OID (numeric): 1.3.6.1.4.1.33049.2.5.4.2.1.5

Node type: OBJECT-TYPE

Type: IbGuid

Access: read-only

Description: The GUID of this IB port. All ports on the same CA shall report a unique mlxIBPortGUID value. This provides a means for uniquely identifying a CA port within a subnet. One port within a node can return the NodeGUID as its PortGUID if the port is an integral part of the node and is not field-replaceable.

What is mlxIBPortGUID?

The GUID uniquely identifying this InfiniBand port; a port that is an integral, non-field-replaceable part of its node may report the same value as its node's GUID instead of a separate port GUID.

Examples

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33049.2.5.4.2.1.5
snmpwalk -v2c -c public <target> MELLANOX-MIB-4::mlxIBPortGUID

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.33049.2.5.4.2.1.5.1
snmpget -v2c -c public <target> MELLANOX-MIB-4::mlxIBPortGUID.1
