HP Enterprise File Services WAN Accelerator manual Modifying Wccp Group Settings, Groups

Control	Description
Add New Service Group	Service Group ID. Specify the service group identification number (from 0 to 255).
	The service group ID is the number that is set on the router. A value of 0 specifies the
	standard http service group.
	Router IP. Specify a multicast group IP address or a unicast router IP address. You can
	specify up to 32 routers. For information on adding additional routers to the group, see
	“Modifying WCCP Group Settings” on page 96.
	Password/Confirm Password. Optionally, you can assign a password to the HP EFS
	WAN Accelerator. This password must be the same password that is on the router.
	WCCP requires that all routers in a service group have the same password. Passwords
	are limited to 8 characters.
	Priority. Specify the WCCP priority for traffic redirection. If a connection matches
	multiple service groups on a router, the router chooses the service group with the highest
	priority. The range is 0-255. The default value is 200.
	Weight. Determine how often the traffic is redirected to a particular HP EFS WAN
	Accelerator. A higher weight redirects more traffic to that HP EFS WAN Accelerator.
	The ratio of traffic redirected to an HP EFS WAN Accelerator is equal to its weight
	divided by the sum of the weights of all the HP EFS WAN Accelerators in the same
	service group. For example, if there are two HP EFS WAN Accelerators in a service
	group and one has a weight of 100 and the other has a weight of 200, the one with the
	weight 100 receives 1/3 of the traffic and the other receives 2/3 of the traffic. The range
	is 0-65535. The default value corresponds to the number of TCP connections your
	appliance supports.
	NOTE: To enable failover support for WCCP groups, define the service group weight to
	be 0 on the backup HP EFS WAN Accelerator. If one HP EFS WAN Accelerator has a
	weight 0, but another one has a non-zero weight, the HP EFS WAN Accelerator with
	weight 0 does not receive any redirected traffic. If all the HP EFS WAN Accelerators
	have a weight 0, the traffic is redirected equally among them.
	Encapsulation Scheme. Specify the traffic forwarding and redirection scheme: Generic
	Routing Encapsulation (gre) or Layer-2 (l2) redirection. Specify either to use Layer-2
	first; if Layer-2 is not supported, gre is used.
	Add Group. Click Add Group to add the group to the Service Group list.
	Remove Selected Groups. To remove an entry, select it and click Remove Selected
	Groups.

5.Click Save to save your settings permanently or click Reset to return the settings to their previous values.

You modify WCCP service group settings, add additional routers to a service group, and set flags for source and destination ports to redirect traffic (that is, the hash table settings) in the Advanced Networking - WCCP Service Group: <group ID> page.

Before you can modify WCCP service group settings, you must create a WCCP service group. For information on creating a WCCP service group, see “Enabling WCCP Groups” on page 94.

For detailed information about hash table settings for WCCP, see the Cisco documentation Web site at http://www.cisco.com/univercd/home/home.htm.
