Dear all
after 20 years of Cabletron/Enterasys in our network and spectrum as
our primary monitoring tool, we had very long discussions with the
representatives of Enterasys a few years ago about the support of
primary environmental attributes on all enterasys gear.
With those attributes I mean: prower supply, fans, ambient temperature
and total user interfaces in a chassis/stack. Finally with the latest 5.02
and 6.03 software tracks on the stacking switches the power and fan
information got available. On the chassis systems those attributes
were always there. – Due to missing or not appropriate temperature
devices in the stacks, the value of the ambient air is not available.
But on the newer S and K chassis, the ambient temperature is back
again ;-) For those who are interested in this attribute, please use the
following OID:
chEnvAmbientTemp OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The ambient temperature of the room in which the chassis
is located. If this sensor is broken or not supported, then
this object will be set to zero. The value of this object
is the actual temperature in degrees Fahrenheit * 10."
::= { chEnv 1 }
[ OID=1.3.6.1.4.1.52.4.1.1.8.1.1 ]
Another attribute I mentioned above is the total user interfaces in a
chassis/stack. We had several times the case, that in a chassis a
module crashed without giving too much information via syslog. Or with
stacks we had some outages, after strange negative power spikes,
when elements of a stack did not revover correctly and remained "black".
In both cases we had no obvious clue, why users had no network anymore.
Only after investigating on the chassis/stacks we found the above
mentioned situations. The only easy way to check for those spurious
module/stack losses we started to watch changes in the "ifNumber"
attribute and correlate negative changes with unplanned outages.
For those of you, who use spectrum as we do, I can provide you with
additional intelligence for power supply and fan monitoring. The
temperature attribute is available only ince a short period of time, so
I haven't done too much here. And the dying module/stack issue is
handled by the new "chassis" intelligence of spectrum 9.2.1 ;-)
So if anyone wants to know more, please contact me directly.
Best regards,
--Fritz.
