Symptom
The OID numbers returned by the images prior to 9.2(1) are incorrect and not usable.
ENTITY-MIB::entPhysicalVendorType.48858 = OID: CISCO-ENTITY-VENDORTYPE-OID-MIB::cevModuleSFPType
ENTITY-MIB::entPhysicalVendorType.48859 = OID: CISCO-ENTITY-VENDORTYPE-OID-MIB::cevModuleSFPType
ENTITY-MIB::entPhysicalVendorType.48863 = OID: CISCO-ENTITY-VENDORTYPE-OID-MIB::cevModuleSFPType
ENTITY-MIB::entPhysicalVendorType.48878 = OID: CISCO-ENTITY-VENDORTYPE-OID-MIB::cevModuleSFPType
ENTITY-MIB::entPhysicalVendorType.48884 = OID: CISCO-ENTITY-VENDORTYPE-OID-MIB::cevModuleSFPType
All transceivers were returning same OID and such OID is not even a leaf node in the MIB definition.
Conditions
SNMP accesses to entPhysicalVendorType of transceivers.
Workaround
