Re^2: Net:SNMP get_table() method failing

hmm, thanks - but no dice I'm afraid.

I tried modifying my call to the sub to be more specific (skipping the scalars), and inserting a print "OID:$oid\n"; just before the get_table() call. This produced the following output:

OID:1.3.6.1.4.1.3309.1.4.17.5
ERROR: Received noError(0) error-status at error-index 1
OID:1.3.6.1.4.1.3309.1.4.4

(there are two separate calls currently - the first fails, the second succeeds).
I then tried a manual snmpwalk using the OID printed - ie. the same one that was passed to get_table(), which produced:

snmpwalk -v1 -c XXXXXX x.x.x.x 1.3.6.1.4.1.3309.1.4.17.5
SNMPv2-SMI::enterprises.3309.1.4.17.5.1.2.1 = Counter32: 1
SNMPv2-SMI::enterprises.3309.1.4.17.5.1.4.1 = IpAddress: 61.115.200.69
SNMPv2-SMI::enterprises.3309.1.4.17.5.1.6.1 = IpAddress: 61.115.200.99
SNMPv2-SMI::enterprises.3309.1.4.17.5.1.10.1 = INTEGER: 1

So, based on the above (and your earlier comments in the CB), I'm fairly convinced now that the problem lies with the get_table() method.

My next approach will be to investigate using get_next_request instead, as you suggested in the CB. (unless you have any other suggestions? ;)

Thanks again for your help :)

It's hard to tell what exactly the problem is without the MIB text and access to the device itself. Plus you've said some indexes return expected results and some don't - adding to the confusion. One of my earlier posts (Re^3: Where is the bug in this Net::SNMP code?) shows example code for pulling out tabular objects of a printer MIB. Another even earlier post (Re^3: SNMP from script conflicts with snmpwalk) discusses issues to do with reading tables and ensuring all objects in a table align. I've never used `get_table` myself, it's a relatively new function introduced into Net::SNMP. If you're unsure exactly what the behaviour is of your code then doing it the hard way (like I like to do) may be your best option so you can easily debug.	[reply] [d/l]
