To generate WAAS before-and-after reports by collecting response time information from the client data source and combining it with information from the Passthru data source.
Step 1 Log in to the WAE.
Step 2 Configure the WAE to optimize the server traffic with the following commands:
config t
tfo optimize full
The purpose of this is to have the NAM VB receive optimized flows to enable post-WAAS impact analysis.
Step 3 Wait for 15-30 minutes (or longer depending on the application) for the Client report to collect data.
Step 4 On the NAM GUI, click Monitor > Response Time for the Client data source and collect the baseline server response time numbers. You can get more metrics by choosing the server and clicking Details.
