I think this is a must have, in order to keep the CPU happy on the IPSLA router.
We have installed 18 "shadow routers" in our call centers dedicated to IPSLA testing.
They are running 20 - 30 tests each, which can impact the performance of the router if they all start simultaneoulsy.
Currently the workaround is the manually configure the tests on each router using the CLI commands to randomize the tests.
Then point IPSLA to the routers to pickup these tests.
I think it would make my life easier. Luckily I have NCM so my script to create bulk IP SLAs is probably a lot easier than others. Still being able to manage/modify them via IP SLA Manager would be better than the way I am doing it now.
