WAAS Pass through traffic

Pradeep H A

Hi Experts,

I am trying to investigate why this Cisco WAVE-694-K9 box is showing the traffic between 10.33.177.0/24 and 10.36.67.0/24 as passthrough. Please suggest me the further troubleshooting steps as this traffic was expected to be optimized but these IPs arent found in sh statistics connection optimized command output. also the other session that seem to be optimized are showing RR as 0.0%

WAAS#sh statistics connection | i 10.33.177.

Hi ,

It looks Aysmmetric routing was seen between 10.33.177.0/24 and 10.36.67.0/24 subents. You need check the routing path flows between two subnets.

WAAS will not optimizing the aysmmetric traffic flow.
