HP Enterprise File Services WAN Accelerator manual Service group

service group	Specifies the service group identification number (ID) (from 0 to
<service ID>	255). The service group ID is the number that is set on the router. A
	value of 0 specifies the standard http service group which redirects
	only HTTP traffic.
router	The router IP is a multicast group IP address or a unicast router IP
<ip_address>	address. A total of 32 routers can be specified.
flags <hash-bit-	Specifies the combination of src-ip-hash, dst-ip-hash, src-port-
identifier>	hash, dst-port-hash,ports-dest,ports-source that define the fields
	the router hashes on and if certain ports should be redirected.
ports	Specifies a comma separated list of up to seven ports that the router
<portnumber>	will redirect. Use only if ports-destor ports-sourceservice flag is
	set.
priority <priority-	Specifies the WCCP priority for traffic redirection. If a connection
number>	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.
password <string>	Specifies the WCCP password. This password must be the same as
	the password on the router. (WCCP requires that all routers in a
	service group have the same password.) Passwords are limited to 8
	characters.
weight <value>	The weight determines 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.
encap_scheme	Specifies the traffic forwarding and redirection scheme: GRE
<string>	encapsulation (gre) or Layer-2 (l2) redirection. The either value uses
	Layer-2 first—if Layer-2 is not supported, gre is used.

Connecting the HP EFS WAN Accelerator to

Your Network in WCCP Deployments

There are two Ethernet cables attached to the HP EFS WAN Accelerator in WCCP deployments:

‹A Straight through cable to the Primary interface. You use this connection to manage the HP EFS WAN Accelerator, reaching it through HTTPS or SSH.

‹A Straight through cable to the WAN interface. You assign an IP address to the In-Path interface; this is the IP address that you redirect traffic to.
