Re: [j-nsp] SNMP polling issue MX
It looks like there were possibly multiple mib2d process bugs. In our
case, restarting mib2d did not always resolve the issue.
The good news is that it does look like 10.2R3 fixes the mib2d issues we
were experiencing. We've been running 10.2R3 (or a derivative) for
several weeks and SNMP appears to be stable.

Juniper is probably tracking it through some internal PR, the

Hrmm supposedly the mib2d memory leak is fixed was 10.2R3, but we never
actually tested it, we just skipped straight ahead to 10.3R2 on new
deployments (as there were many other SNMP bugs still not fixed in 10.2
at the time). A quick and dirty workaround for the memory leak issue is
to periodically restart the mib2d process, which you can do with an
event script like so:
event-options {
generate-event {
/* Adjust ttimer as necessary based on memory consumption */
restart-mib2d time-interval 604800;
}
policy restart-mib2d {
events restart-mib2d;
/* Adjust this too, to something slightly less than above */
within 60 {
not events restart-mib2d;
}
then {
event-script restart-mib2d;
}
}
}

[j-nsp] SNMP polling issue MX
Hi All, We are facing issue in polling SNMP statistics on MX 960 sub-interfaces. JUNOS 10.2R1.8 is running on router. The sub-interfaces statistics are not getting polled on the Reporter software, where as the parent statistics are getting polled. The SNMP statistics can be seen on the router. The issue is with all types of interfaces AE, XE, GE. Nothing wrong seems with the configuration. Thanks Chintan ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
