IP SLA to monitor an ICMP's Latency of destination and take action

Karl Tremblay

Hello group,

 

I need some advices/help on setup. I need to monitor the ping latency value on a destination/host.

In fact, I need to ping a destination IP, based on the latency result, if the latency of the ping(or round trip maybe) is more than lets say 15ms, I would need to shutdown a specific port, and vice-versa, if the ping come back under 12ms no shut the specific port.

 

My question, is it possible to use the IP SLA option to monitor the icmp latency value on a specific host/destination, and based the on result as I said, take a specific interface shut or no shut ? and running forever.

 

I guess I would need to use the IP SLA feature with the addition of  an "event manager applet" for the interface action, also maybe track feature ?

Do you think it's possible ? Is there others options I could use to acheive my goal here ?

 

Device would be cisco 3600 or ASR920.

 

Thanks for help,

 

Karl Tremblay
