Description (partial)

Symptom:
+++ If we change the device mode to appnav controller and run the command  "show accelerator detail" , we would be able to see the connection limit reduced in many accelerators.

+++ For example in 7571 following was the result of the above output in many accelerators when the device mode was application accelerator:

   Policy Engine Config Item            Value
   -------------------------            -----
   State                                         Registered
   Default Action                       Use Policy
   Connection Limit                     60000
   Effective Limit                           59900
   Keepalive timeout                    5.0 seconds

+++But once the device mode is changed to appnav-controller, the connection limit for various accelerators reduces to 50000.

   Policy Engine Config Item            Value
   -------------------------            -----
   State                                         Registered
   Default Action                       Use Policy
   Connection Limit                     50000
   Effective Limit                           49900
   Keepalive timeout                    5.0 seconds

Conditions:
+++ Occurs in WAAS devices having appnav modules such as WAVE-7571-K9 and WAVE-8541-K9 ( known to be found in these till now)
+++ Occurs once the device mode is change to appnav controller
+++ It is a document bug and should be mentioned under "Appnav Interoperability" section of the release notes:
http://www.cisco.com/c/en/us/td/docs/app_ntwk_services/waas/waas/v535/ws535xrn.html

or under "configuring Appnav" in the configuration guide for WAAS 5.3, 5.4
