WAAS and IP SLA operation

sallison · ‎07-06-2010

we are currently using the IP SLA udp jitter measurement to monitor our voice paths accross the WAN. If we implement a partial WAAS across the same WAN the voice traffic will be acellerated but not the IP SLA jitter measurement. Does this mean that when WAAS is implemented IP SLA is limited in its use?

Hi Steve,

The answer to your question depends on 1) how you deploy WAAS and 2) how you use IP SLA. If you deploy WAAS using WCCP for interception, UDP traffic will never be intercepted. If the WAAS device is deployed inline, all traffic flows through the WAAS device, so an IP SLA probe using UDP will be subject to WAAS pass-through handling behavior.

What are you trying to measure with regards to WAAS?
