HP STORAGEWORKS ENTERPRISE FILE SERVICES WAN ACCELERATOR DEPLOYMENT GUIDE 75
7 - WCCP DEPLOYMENTS
service group
<service ID>
Specifies the service group identification number (ID) (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 which redirects
only HTTP traffic.
router
<ip_address>
The router IP is a multicast group IP address or a unicast router IP
address. A total of 32 routers can be specified.
flags
<hash-bit-identifier
>
Specifies the combination of src-ip-hash, dst-ip-hash,
src-port-hash, dst-port-hash, ports-dest, ports-source that define
the fields the router hashes on and if certain ports should be
redirected.
ports
<portnumber>
Specifies a comma-separated list of up to seven ports that the router
will redirect. Use only if ports-dest or ports-source service flag is
set.
priority
<priority-number>
Specifies 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.
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
eight 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
<string>
Specifies the traffic forwarding and redirection scheme: GRE
encapsulation (gre) or Layer-2 (l2) redirection. The either value uses
Layer-2 first—if Layer-2 is not supported, gre is used.
