[Xymon] Devmon tests clear but snmpwalk works

[Phil Crooker]

How do the IOS versions compare between the switches that work and those that don't?

?

Hi Jeremy

Yep, did this after reading through your other thread again.

Still no change in behavior.  Tis very strange as we have many of this model switch responding correctly and the cisco router (and another type of Cisco switch) installed on those sites are working as expected.

Still looking...

Thanks

Can you confirm if positive IDs are accepted by devmon? If not, this might be a red herring.

Try applying this adjustment to devmon and see if it helps. This forces the SNMP_Session module to avoid negative request IDs:

*** devmon.orig     2011-05-06 15:32:03.000000000 +1000
--- devmon        2016-05-30 12:26:14.000000000 +1000
***************
*** 30,35 ****
--- 30,37 ----
   # Do start-up housekeeping
    initialize($VERSION);

+   $SNMP_Session::default_avoid_negative_request_ids = 1;
+
   # Enter main loop
    do_log("Entering poll loop", 0);
    while (1) {
