Hi,
Does anyone know how to configure ipsla such that cisco sends 2 pings packets before it marks the sla down?
thx,

Use the "delay down" option with IP SLA.
So if your ping frequency is 30 seconds then you would do -
ip sla

Hi Jon,
Thank you for your response. Currently the frequency/interval is set to 1 second. If delay down is set to 2 sec, the second ICMP Request is sent 1 second after the first Request before declaring reachability down.
Is it possible to send more than 2 ICMP Requests within each interval?
thx,
Shelley

Hi Jon,
I have a cisco 7600. It will send an icmp request every second. If the icmp response is not received, 3 consecutive icmp requests will be sent. SLA reachability down will be reported after all 4 icmp responses are not received. The following diagram illustrates my goal.
Sender
--------------------------------------- 0 second
-> 0 sec (1st icmp Request is sent out)
-> 50ms (no response, send 2nd icmp after timeout)
-> 50ms (no response, send 3rd icmp after timeout)
-> 50ms (no response, send 4th icmp after timeout)
50ms Report SLA reachability down
--------------------------------------- 1 second
--------------------------------------- 2 second
Question: will the following configuration achieve my goal?
ip sla 100
icmp-echo 10.32.24.1 source-ip 10.32.24.2
timeout 50
frequency 1
ip sla monitor reaction-configuration 100 react timeout threshold-type consecutive 3 action-type triggerOnly
thx,
