IP Sla Option for lost packets threshold ?

[usmansa1]

Hi,

I am looking to implement ip-sla with HSRP. My requirement is to trigger the fail-over if at-least three packets are lost. For example if the track IP configured is 8.8.8.8 then the threshold should be triggered only if at-least three packets are lost towards 8.8.8.8. I am trying to figure out the way but couldn't find any option. I am using C860-UNIVERSALK9-M. Can any one help me

Hi,

Your Configuration will be like:

R1(config)# ip sla 1
R1(config)# icmp-echo 8.8.8.8 source-interface XXXXX
R1(config)# timeout 1000
R1(config)# threshold 3
R1(config)# frequency 2

The ICMP Echo probe sends an ICMP Echo packet to next-hop IP 8.8.8.8 every 2 seconds, as defined by the “frequency” parameter.

Timeout sets the amount of time (in milliseconds) for which the Cisco IOS IP SLAs operation waits for a response from its request packet.

Threshold sets the rising threshold that generates a reaction event.
