smHardwareVpdHardwareRevisionString
Module: CME-MIB
OID (symbolic): CME-MIB::smHardwareVpdHardwareRevisionString
OID (numeric): 1.3.6.1.4.1.2.3.51.2.2.21.6.1.1.20
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: Switch module hardware VPD hardware revision in string format. For consistent results, view as a table and not as individual entries. If a hardware revision is programmed in the OEM VPD area for this component, then this MIB object should be used.
What is smHardwareVpdHardwareRevisionString?
This OCTET STRING gives the hardware revision of the switch/I-O module (SM) installed in the chassis written out as text, and the MIB says it should be used instead of the plain-integer HardwareRevision object whenever the OEM VPD area has this string programmed. An admin relies on the string form to avoid ambiguity, since a numeric revision code alone can't capture vendor-specific revision letters or suffixes. For example, smHardwareVpdHardwareRevisionString reveals the exact revision text of the installed switch module when deciding whether it supports a feature that shipped only from a certain board revision onward.
