[j-nsp] SRX240H Cluster & SNMP

[Wayne Tucker]

I have a couple of SRX240H clusters running 11.2R6.  I also have an
SRX650 cluster running 11.2S6.  I don't see anything in my logs to
indicate that I'm getting errors and none of my graphs show signs of
failed polls.

I doubt it matters, but I'm polling the devices through their loopback
interfaces.  I also filter out some of the interfaces and filter
duplicates:

> show configuration snmp | display inheritance | except ##
filter-interfaces {
    interfaces {
        fxp2;
        gre;
        ipip;
        lo0.16384;
        lo0.16385;
        lo0.32768;
        lsi;
        mtun;
        pimd;
        pime;
        tap;
    }
}
filter-duplicates;

Does it seem to happen the most when there are lots of queries going
through?  Are you doing row-based or column-based queries (one
interface at a time or the same counter across several interfaces)?
The former is supposed to perform better (so, for instance, an
snmpwalk is fairly processor intensive).

Any signs of trouble on your control or fabric interfaces?

Has JTAC already had you enable tracing for SNMP?

:w

Seems that when running various versions (11.2R7.4 and 11.4R4.4, so far) on a 240H cluster, SNMP doesn't work properly and starts spitting out 'noSuchObject' errors on perfectly valid queries like when querying the interfaces MIB.  I should also mention that the OIDs it seems to have a problem with are primarily ones that have to do with the backup chassis in redundancy-group 0 (ge-5/0/0 through ge-5/0/15).  JTAC has thus far been unsuccessful at assisting me.
