IP SLA ICMP-ECHO for a range of request-data-size

[Ivan Uribe]

Hello there!

I had an issue with a couple of WAN links, issue was related with packet loss on the ISP cloud. When I was testing, I noticed that packet loss was occurred on pings with a size higher than 1300, issue was resolved by the ISP but customers experienced slowness for couple of hours which is unacceptable, now we installed a backup link and I would like to configure IP SLA ICMP-ECHO to track the packet loss and switch to the backup link. I know it could be something quick and easy like the following:

ip sla 10
icmp-echo 5.5.5.5 source-ip 2.2.2.2
frecuency 300
request-data-size 1300
tos 160
tag ISP_LocationAtoB
ip sla schedule 10 life forever start-time now

But is there a way to setup an icmp-echo operation for a range of sizes (1000, 1300, 1500) and monitor the response in the same SLA operation???

You would need to setup up multiple IP SLA's, and then monitor them as a group.  For example, something like:

track 10 ip sla 10
track 20 ip sla 20
...

track 100 list boolean or
 object 10
 object 20
...

thanks Philip, I'll try and see how it works.
