Hi All,
We are doing a test to check the agent to handle large sub-ids after
replacing the instance sub identifiers in the attribute id,
with the largest 32 bit unsigned long. A SNMPv2C agent is expected to
respond back with a noSuchInstance value.
The above result are as per RFC 3416 :
---------------------------------------------------------------------------------------
Upon receipt of a GetRequest-PDU, the receiving SNMP entity processes
each variable binding in the variable-binding list to produce a
Response-PDU. All fields of the Response-PDU have the same values as
the corresponding fields of the received request except as indicated
below. Each variable binding is processed as follows:
(1) If the variable binding's name exactly matches the name of a
variable accessible by this request, then the variable
binding's value field is set to the value of the named
variable.
(2) Otherwise, if the variable binding's name does not have an
OBJECT IDENTIFIER prefix which exactly matches the OBJECT
IDENTIFIER prefix of any (potential) variable accessible by
this request, then its value field is set to "noSuchObject".
(3) Otherwise, the variable binding's value field is set to
"noSuchInstance".

/opt/servers/netsnmp/bin/snmpget -v 2c -c private 172.16.8.86
1.3.6.1.2.1.92.1.1.1.0
NOTIFICATION-LOG-MIB::nlmConfigGlobalEntryLimit.0 = Gauge32: 1000
The subidentifier is changed to 4294967295 from 0. But the below query
returns "noSuchObject" in place of "noSuchInstance".
/opt/servers/netsnmp/bin/snmpget -v 2c -c private 172.16.8.86
1.3.6.1.2.1.92.1.1.1.4294967295
NOTIFICATION-LOG-MIB::nlmConfigGlobalEntryLimit.4294967295 = No Such
Object available on this agent at this OID
Is there something wrong with my understanding ?
Regards,
Manjit
