Configure mode negotiation
- The Packet Forward Method determines how traffic is transmitted from the WCCP router to the proxy.
- The Packet Return Method specifies the method used to return traffic back to the WCCP router.
If you change the forward/return method configuration while there is an active connection with the WCCP device, in order to re-negotiated the method you must force the current connection to terminate. Typically, this means turning off the service group on the WCCP device for 60 seconds. See the documentation for your WCCP device.
If multiple proxies are installed in your environment, each with WCCP enabled, but configured with different Packet Forward and Packet Return Methods, traffic may not be processed. Some routers support only a single Packet Forward Method within a group and may forward packets to the other proxies using a method they do not support.
Typically the router supports only one method, and the forward and return methods match.
