chassisUUID
Module: CME-MIB
OID (symbolic): CME-MIB::chassisUUID
OID (numeric): 1.3.6.1.4.1.2.3.51.2.2.21.1.1.4
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: Machine UUID (Universal Unique ID information) (from System BIOS). This field must be 32 alpha numeric characters.
What is chassisUUID?
This read-write octet string, required to be 32 alphanumeric characters, reports the chassis's universally unique identifier from its vital product data in the system BIOS. Asset-management and provisioning systems rely on this UUID as a globally unique key to track this specific physical chassis distinct from any other, even ones of identical model and type. For example, a data center management system would key its inventory database on this chassisUUID value rather than the machine type and model fields, which could be duplicated across units.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.2.21.1.1.4 snmpwalk -v2c -c public <target> CME-MIB::chassisUUID
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.2.21.1.1.4.1 snmpget -v2c -c public <target> CME-MIB::chassisUUID.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.2.3.51.2.2.21.1.1.4.1 s <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> chassisUUID.1
