EEM to trigger on IP SLA RTT threshold on 4331?

Hi,

 

Trying to find out how to get a Cisco 4331 EEM to trigger on IP SLA RTT threshold instead of timeout.  I found a configuration that seems like it might work, tested it on 1841 and it took the command (event ipsla operation-id 11 reaction-type rtt), but my 4331 doesn't have the EEM applet "event ipsla..." option.  Is there another method?  Why would a much more expensive router have less options when it comes to event types to trigger EEM?

It may depend on your license or perhaps the IPSLA event detector wasn't compiled into your image.  This has happened before due to resource concerns or simple oversight.  You could still make this work by triggering a syslog message with the threshold violation and have EEM react to that syslog:

ip sla enable reaction-alerts

ip sla logging traps

I don't have an example syslog off hand, but when you configure that, you should see the message generated, and then you can craft a syslog regexp for it.

Re: EEM to trigger on IP SLA RTT threshold on 4331?

Well see... that's kind of the problem. I know the command isn't supported under EEM on the 4331, per my original post. I am looking more for some inside knowledge on a reason why (is there some other method or feature I'm NOT aware of?) or was it removed for no reason? Is there a work around? Something a feature set list won't really assist with. Thanks anyways.

i looked at ipbase have EEM feature supported in 4331

can you post EEM script and what is the error you getting when you creating EEM event ?

Yes, we have EEM set up on the 4331, so I know that is supoorted.  On an 1841 I can enter event trigger "event ipsla operation-id 11 reaction-type rtt".  But on the 4331, event trigger "ipsla" is no longer an option.
