What is entPhysicalFirmwareRev?

Reports the vendor's firmware revision string for this physical component, converted to printable text if stored internally in binary form; an empty string means no firmware is associated or the revision is unknown. An admin checks this to confirm a card or module is running the expected firmware version.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.47.1.1.1.1.9
snmpwalk -v2c -c public <target> ENTITY-MIB::entPhysicalFirmwareRev

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.47.1.1.1.1.9.1
snmpget -v2c -c public <target> ENTITY-MIB::entPhysicalFirmwareRev.1
