HP StorageWorks Enterprise File Services WAN Accelerator 3.0.4 Command-Line Interface reference manual (AG421-96004, March 2007)

HP STORAGEWORKS EFS WAN ACCELERATOR COMMAND-LINE INTERFACE REFERENCE MANUAL 197
4 - CONFIGURATION-MODE
C
OMMANDS
The no command option disables WCCP support.
NOTE: The following section assumes you are familiar with WCCP. For detailed information
about WCCP, see the Cisco documentation Web site at
http://www.cisco.com/univercd/home/home.htm.
To enable WCCP, the HP EFS WAN Accelerator must join a service group at the
router. A service group is a group of routers and HP EFS WAN Accelerators which
define the traffic to redirect, and the routers and HP EFS WAN Accelerators the traffic
goes through.
To enable failover support with 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.
If the source or destination flags are set, the router redirects only the TCP traffic that
matches the source or destination ports specified.
For detailed information about configuring WCCP, see the HP StorageWorks
Enterprise File Services WAN Accelerator deployment guide.

Parameters
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.
routers <routers> A comma-separated list of router IPs (maximum of 32).
encap_scheme
[either|gre|12]
Specifies the traffic forwarding and redirection scheme:
• gre. Generic Routing Encapsulation (gre)
• l2. Layer-2 redirection.
• either. Layer-2 first; if Layer-2 is not supported, then gre.
flags <flags> Specifies the fields the router hash on and if certain ports should be
redirected. Specify a combination of src-ip-hash, dst-ip-hash, src-
port-hash, dst-port-hash, ports-dest, ports-source.
ports <ports> Specifies a comma-separated list of up to 7 ports that the router will
redirect. Use only if ports-dest or ports-source service flag is set.
