Introduction
The WAAS system consists of a set of devices called wide area application engines (WAEs) that work together to optimize TCP traffic over your network. WAAS Central Manager GUI is used to centrally configure and monitor the WAEs and application policies in your network. The Cisco WAAS uses redirect method and assignment method to move packets between router to waas and to load balance packets among WAAS respectively.
Problem
Swapped a new WAAS appliance (WAVE-694-K-9) in place of an older appliance as part of an upgrade. The replacement and registering the new appliance to the Central Manager seemed to go as planned as the new appliance has successfully registered and assumed the identity of the old device. The new device is also showing 'online' in Central Manager. Also made sure that the "ip wccp redirect 61/62" commands are back on the router interfaces where the redirect should happen. However it seems that redirection is not happening. The command, "show ip wccp" on the router shows no packet count incrementing on the router and other commands run on the waas is not showing any sessions.
Description
Check the output of following troubleshooting command
waas01#show wccp status
WCCP Interception :
Configured State : Enabled
Services Enabled on this WAE:
-NONE-
Make sure that you have configuration for services like wccp tcp promiscous 61/62 etc enabled on WAE.
wccp router-list 1
wccp tcp-promiscuous service-pair 61 62
router-list-num 1
Also check if the WAE and the router can ping each other. On the router check wccp details.
rtr01#show ip wccp

Resolution
The router doesn't seem to recognize WAE, which means that WAE is not configured properly. Check that the config of wccp on WAE is correct.
wccp router-list 8
wccp tcp-promiscuous service-pair 61 62
router-list-num 8
