SNMP OID for getting manufacturer serial number with SNMP version 1

I'm unable to get the manufacturer serial number when I do an SNMP get on an OID .2.47.1.1.1.1.11.1.0. If I do an snmpget with the below command on the OID with the command:

snmpget -v1 -c public 192.168.4.99 .2.47.1.1.1.1.11.1.0

I get the message:

Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: joint-iso-ccitt.47.1.1.1.1.11.1.0

I did search on google for the possible cause of error by going to this SO thread as it is caused by missing the instance subidentifier.

I performed an SNMPtranslate for the OID and I got the below string joint-iso-ccitt.47.1.1.1.1.11.1.0.

And when I performed an snmpwalk on the OID by the below command i get the message as END OF MIB.

snmpwalk -v1 -c public 192.168.4.1 .2.47.1.1.1.1.11.1.0

Please let me know where I'm going wrong and let me know the exact generic OID to get the manufacturers serial number.

If you start with walking the top of the MIB tree, you'll soon find out which variables your equipment supports:

snmpwalk -v1 -c public -Ont 192.168.4.1 .1

Remove the "-Ont" to get translated names, where possible, instead of the fully numeric OIDs.

If you're looking for vendor-independent data, you could look into a MIB that most equipment supports, SNMPV2-MIB:

http://www.ietf.org/rfc/rfc3418.txt

However, you'll find it does not contain any serial number variable. Most vendors provide a vendor-specific (or product-specific) MIB which will define, among other things, serial number. However, like most things in SNMP, it's entirely up to each vendor which MIBs they choose to implement.

Who tells you the OID is .2.47.1.1.1.1.11.1.0?

Seriously speaking, a normal OID starts with .1, except .0.0 which is very special.
