slEntPhysicalHardwareRev
Module: SL-ENTITY-MIB
OID (symbolic): SL-ENTITY-MIB::slEntPhysicalHardwareRev
OID (numeric): 1.3.6.1.4.1.4515.1.3.6.1.1.1.4
Node type: OBJECT-TYPE
Type: SnmpAdminString
Access: read-only
Description: The vendor-specific hardware revision string for the physical entity. The preferred value is the hardware revision identifier actually printed on the component itself (if present).
Note that if revision information is stored internally in a non-printable (e.g., binary) format, then the agent must convert such information to a printable format, in an implementation-specific manner.
If no specific hardware revision string is associated with the physical component, or this information is unknown to the agent, then this object will contain a zero-length string.
What is slEntPhysicalHardwareRev?
This value reports the vendor's hardware revision identifier for this physical entity, matching what is printed on the component itself, or a zero-length string if unknown. Admins compare this across identical card types to check for known hardware-revision-specific bugs or compatibility limits before a firmware upgrade. For example, a value of "Rev C" would indicate the card is a later hardware spin than "Rev A" units elsewhere in the same chassis.
