entPhysicalSerialNum
Module: ENTITY-MIB
OID (symbolic): ENTITY-MIB::entPhysicalSerialNum
OID (numeric): 1.3.6.1.2.1.47.1.1.1.1.11
Node type: OBJECT-TYPE
Type: SnmpAdminString
Access: read-write
Description: The vendor-specific serial number string for the physical component.
What is entPhysicalSerialNum?
The manufacturer's serial number for this physical component, preferably matching what's printed on the hardware itself; it's set automatically on first discovery if known, and only needs to be writable if the agent can't determine serial numbers on its own. An admin can read this for asset tracking or RMA purposes, and in some implementations write it in if the device didn't detect it automatically.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.47.1.1.1.1.11 snmpwalk -v2c -c public <target> ENTITY-MIB::entPhysicalSerialNum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.47.1.1.1.1.11.1 snmpget -v2c -c public <target> ENTITY-MIB::entPhysicalSerialNum.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.47.1.1.1.1.11.1 s <value>
