I'm having a problem polling my high capacity devices. The following command can take up to 18 minutes to complete due to the number and interfaces. The command is /usr/bin/snmpwalk -v2c -c 'XXXXX' -Pu -OQUs -m IF-MIB -M /opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp 'udp':'x.x.x.x':'161' ifEntry. Do the pro or enterprise versions change the way they poll devices? Are there configuration setting I can change to make? The devices I am polling have upwards of 1000 interfaces.

It seems that that SNMP stack used on the Cyan devices is broken in such a way that we had to disable bulkwalk, which will totally tank polling speed. Some devices with poor stacks will frequently drop queries half way through, which makes them next to impossible to poll with bulkwalk.
You might get better polling from using the separate get method, but I don’t think that’s in CE at the moment.
Thanks,
Adam.

Hi,
It is, but I can’t guarantee that it’ll fix your problem. It’s not always possible to work around vendors using broken SNMP stacks.
I’ll contact you off list to test.

I get that. Ciena changed or rewrote some parts of their snmp stack. No sure if bulkwalk is still broken or not.
