Hi ,
I am getting "snmpwalk: security service 3 error parsing ScopedPDU " and
"Timeout: No Response from localhost" while doing snmpwalk on bgpI
SNMPv2 walk
-------------------
snmpwalk -v2c -c public localhost 1.3.6.1.2.1.15.4
registered debug token recv, 1
recv: error while parsing VarBindList:

Captured PCAP files between 5.7.2 client <---> 5.8 server and 5.8 client
<--->s5.8 server
My observations on the PCAP file.
server is 5.8 ---client 5.7.2
------------------------------------
the client is sending snmpwalk request for bgpIdentifier
the server is responding to the client as below.
variable-bindings: 1 item
RFC1213-MIB::mib-2.15.3.1.1.4.0.0.41.218
(1.3.6.1.2.1.15.3.1.1.4.0.0.41.218): <MISSING>
Object Name: 1.3.6.1.2.1.15.3.1.1.4.0.0.41.218
(RFC1213-MIB::mib-2.15.3.1.1.4.0.0.41.218)
Value (IpAddress): <MISSING>
client is returning the o/p as 0.0.0.0 for bgp identifier.
case 2:
----------
server is 5.8 or 5.9 ---- client 5.8 or 5.9
the client is sending snmpwalk request for bgpIdentifier OID
the server is responding to the client as below.

(RFC1213-MIB::mib-2.15.3.1.1.4.0.0.41.218)
Value (IpAddress): <MISSING>
the client is resending requests bgpIdentifier
The issue is seeing on net-snmp 5.8 and net-snmp 5.9 SNMP clients.
Are there any behavioral changes between 5.8 and 5.7.2 clientsimplimentation?
Thanks,
Chandra Sekhar.
Thanks
