7.1.2-080 7.1.3-014 7.5.0-000

Description (partial)

Symptom:
WSA uses lowest interface IP address in data routing table for negotiating WCCP.  This IP address will be used as the web cache identity (seen in show ip wccp command output) on the router/ASA/switch when redirecting packets using WCCP. It can be seen in the "Web-Cache Identity Element" > "wccp.web_cache_identity.ip" field in a packet capture on the WSA.

Conditions:
You have configured multiple WCCP service IDs on the WSA attempting to use a different service ID on each of the WSA interfaces. But, WSA continues to show up with only the lowest data interface IP address on the router/switch/ASA
