ibSmaNodeGuid
Module: IB-SMA-MIB
OID (symbolic): IB-SMA-MIB::ibSmaNodeGuid
OID (numeric): 1.3.6.1.3.117.3.1.1.7
Node type: OBJECT-TYPE
Type: IbGuid
Access: read-only
Description: The GUID of this node. The node can be a Host Channel Adpater (HCA), Terminal Channel Adapter (TCA), switch, or router. All ports on the same node shall report the same NodeGUID value. This provides a means for uniquely identifying a node within a subnet and helps to determine the co-location of the ports.
What is ibSmaNodeGuid?
The node's own 64-bit Globally Unique Identifier, reported identically by every port on the node (HCA, TCA, switch, or router). This is the primary key an admin uses to uniquely identify a physical device in the fabric and to correlate its ports.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.3.117.3.1.1.7 snmpwalk -v2c -c public <target> IB-SMA-MIB::ibSmaNodeGuid
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.3.117.3.1.1.7.1 snmpget -v2c -c public <target> IB-SMA-MIB::ibSmaNodeGuid.1
