Hi to all,
I am new to net-snmp and I have a problem accessing the data of a table.
I have already noticed the previous discussion indexed "table problems",
but I followed the rule init_FILENAME and I still have problem.
I ran mib2c.create-dataset.conf on my MIB file. The .c and .h files are
attached to the mail. I tried to follow the example given in data_set.c
The table in the MIB is of the form
intracomTable OBJECT-TYPE
SYNTAX SEQUENCE OF IntracomTableEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION ""
::= { F5000grt 2 }
intracomTableEntry OBJECT-TYPE
SYNTAX IntracomTableContent
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION ""
INDEX { intracomTableId }
::= { intracomTable 1 }
IntracomTableEntry ::= SEQUENCE {
intracomTableId OCTET STRING,
intracomTableContent1 OCTET STRING,
intracomTableContent2 OCTET STRING
}
intracomTableId OBJECT-TYPE
SYNTAX OCTET STRING ( SIZE (1..32))
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION ""
::= { intracomTableEntry 1 }
intracomTableContent1 OBJECT-TYPE
SYNTAX OCTET STRING
MAX-ACCESS read-create
STATUS current
DESCRIPTION ""
::= { intracomTableEntry 2 }
intracomTableContent2 OBJECT-TYPE
SYNTAX OCTET STRING
MAX-ACCESS read-create
STATUS current
DESCRIPTION ""
::= { intracomTableEntry 3 }
the snmptranslate works fine.
I have no problem at compilation, but as soon as I start the snmp
daemon, I can see all the debugging related to intracomTable.
However, the snmwalk does not work properly.
Giving snmpwalk -v2c -c public localhost intracomTable returns
INTRACOM-F5000-VOIPV1-MIB::intracomTable = No Such Object available on
this agent at this OID
I will appreciate any idea/help, because I am stucked.
Thank you in advance,
Pavlos
