 Analysis from the Packet Capture. The OID with the issue “1.3.6.1.2.1.47.1.1.1.1.2.300901122” belongs to the Cisco Entity MIB. As cross verified in the Domain logs the error occurs when Smarts Probes this Entity MIB. Détails OID Module ENTITY-MIB (CISCO) Nom entPhysicalDescr Access readonly Status current Description A textual description of physical entity. This object should contain a string that identifies the manufacturer's name for the physical entity, and should be set to a distinct value for each version or model of the physical entity. Syntax SnmpAdminString (SNMP-FRAMEWORK-MIB)  As seen from the response form the device, it is evidently clear that the device is responding 38 bytes of data over the packet. This violates the RFC Standard as the OctetString size should be 0-255 bits i.e. ~32 bytes. Please find the details below:  SNMP-FRAMEWORK-MIB::SnmpAdminString ::= TEXTUAL-CONVENTION  DISPLAY-HINT "255t"  STATUS       current  DESCRIPTION "An octet string containing administrative  information, preferably in human-readable form.  .... represented using the ISO/IEC  IS 10646-1 character set, encoded as an octet  string using the UTF-8 transformation format  described in [RFC2279]....."  SYNTAX       OCTET STRING (SIZE (0..255))  Row -174 This is the issue with the Device responding incorrect packet, and should be handled by the device vendor.  Kindly reach out to the device vendor for the resolution of the issue. Cisco will give the correct packet capture entry and customer had to add the same to device and delete and add the device which can resolve the error. Regards, Bhanu Chandra
Hi All,  We have been facing the discovery error issues repeatedly with many devices.  I have gone through all the Knowledge base articles from EMC but didn't find the exact appropriate solution.  Would be grateful if any one help me out in this.
