entPhysicalHardwareRev
Module: ENTITY-MIB
OID (symbolic): ENTITY-MIB::entPhysicalHardwareRev
OID (numeric): 1.3.6.1.2.1.47.1.1.1.1.8
Node type: OBJECT-TYPE
Type: SnmpAdminString
Access: read-only
Description: The vendor-specific hardware revision string for the physical component.
What is entPhysicalHardwareRev?
This object contains the vendor-specific hardware revision identifier for a physical component (such as a line card, processor, or power supply), typically matching a version string printed on the component itself. If hardware revision information is not available or stored in a non-printable format, it is converted to a readable string by the agent. Network operators use this to track equipment firmware versions and hardware revision levels for compatibility and support purposes.
Examples
Walk all instances (SNMPv2c):
