nodeSerial
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::nodeSerial
OID (numeric): 1.3.6.1.4.1.277.1.3.7
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The serial number (i.e., Ethernet Addr) of the switch.
What is nodeSerial?
This reports the switch's serial number, noted in the description as being derived from its Ethernet MAC address rather than a separately stamped serial. An asset-tracking system uses nodeSerial as the unique hardware identifier when reconciling SNMP-discovered devices against a physical inventory list.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.3.7 snmpwalk -v2c -c public <target> CASCADE-MIB::nodeSerial
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.3.7.1 snmpget -v2c -c public <target> CASCADE-MIB::nodeSerial.1
