mlxIBPortGUID

Module: MELLANOX-EFM-MIB

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

Read-only IbGuid giving the globally unique ID of this IB port; ports on the same CA each report a distinct value, except that an integral, non-field-replaceable port may reuse the node's GUID. Uniquely identifies this specific port within the InfiniBand subnet for topology and SM correlation.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33049.2.5.4.2.1.5
snmpwalk -v2c -c public <target> MELLANOX-EFM-MIB::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-EFM-MIB::mlxIBPortGUID.1
