As a best practice, and for easier ACL management, we’ll configure two Service Groups (TCP, UDP) for outbound traffic redirection and two Service Groups (TCP, UDP) for inbound traffic redirection.Each Silver Peak appliance has a default weight of 100, which we’ll leave unchanged.To configure WCCP on the first appliance, you’ll need to use the Appliance Manager’s Configuration - WCCP page to do the following:
• Note ACTIVE - Designated will be the state for one Silver Peak appliance — this is the device that owns the communication for WCCP with the routers.
1 From the menus, select Configuration > WCCP. The Configuration - WCCP page appears, with the Service Group tab displayed.
2 At the top of the page, select Enable WCCP.
To optimize the two most commonly used protocols — TCP and UDP — you’ll create two WCCP service groups in the Silver Peak appliance.If you intend to optimize traffic other than TCP and UDP, create a new service group for that protocol, and select the protocol name from the Protocol drop-down menu when creating the service group.
1 Click Add Service Group. The new WCCP Service group appears with the default settings.
2 In the Service Group ID field, enter the WCCP Service Group number you entered on the router as a placeholder for the TCP protocol. On the router, we entered 53.

a In the Forwarding Method field, select either. Either allows the appliance and the router to negotiate the best method for assignment. That is, GRE (Generic Routing Encapsulation) or L2.
b
c In the Assignment Method field, leave the default of either. Either allows the appliance and the router to negotiate the best method for assignment. That is, hash or mask.
d Leave Force L2 Return deselected.

• If you’re not configuring the tunnel traffic for auto-optimization, then accept the default of lan-ingress. This is the assumption made for this example, since all redirection will be from the LAN to the WAN.
• wan-ingress assignment detail is only required when redirection is needed from the WAN to the LAN, when using TCP/IP auto-optimization.
• custom is used to provide granular control of flow distribution. Contact Silver Peak Technical Support for assistance.

7 For Compatibility Mode, select the option appropriate for your router. If a WCCP group is peering with a router running Nexus OS, then the appliance must adjust its WCCP protocol packets to be compatible. By default, the appliance is IOS-compatible.
