RE: [nv-l] Query regarding MIB Data Collector of NetView 7.1.3

["Manish Purwar" <manishp@in.niksun.com>]

I will open a support request on this issue, and ask for an enhancement

request to be created to extend snmpv2 mib support in snmpcollect

as suggested by Todd. Then this will be a very useful application for

us.

 

Thanks a lot to Todd and Gareth for their useful suggestions!!!

 

Best regards,

Manish Purwar

snmpCollect would still need code added to handle all the new SNMP V2 data types, like Counter32, Gauge32, and so on. So as long as the data type is of the sort that snmpcollect can currently support, you should be ok on using a V2 MIB in a data collection. But this is NOT the case for all SNMP V2 MIBs, otherwise the GUI probably would have been updated by now. Support for v2 is not as simple as modifying the GUI from what I understand.

That's because they use the xnmbrowser--the snmp mib browser for the
snmpv1 mib hierarchy.

No.

The data collector can be used if you hand code the OID into
/usr/OV/conf/snmpcol.conf The syntax is documented in the file itself
in comments.  Once you edit that file by hand, ovstop/ovstart
snmpcollect

While the mib collector uses snmpv1 PDU's to send its GET requests, it
all works fine because snmpv2 agents are required to respond to v1
requests.

It's unfortunate that NetView's GUI imposes this artificial
limitation.   If you feel as I do about it, open a support request on
tihs issue, and ask for an enhancement request to be created to extend
snmpv2 mib support in snmpcollect.  I see no reason why they couldn't
easily change the GUI to use the snmpv1/v2 mib database and the
xnmbrowser2 to do that selection instead.
