Monitor and Tweak Temperature Thresholds on Catalyst 6509 running Cisco IOS using SNMP

Hey all,

We have two sets of Catalyst 6509s in our production enviroment and we want to ensure that when the temperature of the units reach a specific threshold (+ or - 5%), that a trap can be sent to our Network Monitoring Centre (syslog) allowing them to notify us. I know how to configure the snmp envmon traps, but I want to be able to tweak the thresholds values (just like with CPU). Has anyone ever done this and/or know if it's possible?

Thanks,

neocec

Re: Monitor and Tweak Temperature Thresholds on Catalyst 6509 ru

No, this is not possible.  The temperature thresholds are built into the code.  However, using the Embedded Event Manager, you could monitor the temperature of the switch and generate customized events when your thresholds are crossed.  For example:

event manager applet watch-temp

event snmp oid 1.3.6.1.4.1.9.9.13.1.3.1.3.10 get-type exact entry-val 70 entry-op ge poll-interval 10

action 1.0 syslog msg "EARL outlet temperature is $_snmp_oid_val"

The value of "10" at the end of the OID is specific to my switch.  It corresponds to the EARL outlet temperature.  You would need to perform an SNMP walk of your ciscoEnvMonTemperatureStatusTable to figure out what indexes exist for your switches.

Neocec;

  If you are still in need of an answer to this question, you may want to move this thread to the Network Infrastructure>Network Management community.
