4. Use the controls to set base service settings for a profile, as described in the
following table.
5. Click Apply to Working to apply these settings to the specified working profile.
When you apply page settings, the values are applied to the running configuration
but not saved permanently. The Save Configuration icon displays a flashing
orange arrow to remind you to save your configuration.
6. To save the settings permanently, click Save.
To revert to the running configuration, click Reset.
Control Description
Settings will be applied to profile Select the name of the profile you want to configure from the drop-down list.
In-Path Enable In-Path Support. Check this box to enable in-path support.
Reset Existing Client Connections on Startup. Check this box to enable kickoff. If you
enable kickoff, connections that exist when the HP EFS WAN Accelerator service is
started and restarted are disconnected. When the connections are retried they are
optimized.
Generally, connections are short lived and kickoff is not necessary. It is suitable for very
challenging remote environments. For example, in an environment with 128 kbps and 1.5
seconds of latency, you might want to abort an HTTP download so that your traffic is
optimized, whereas in a remote branch office with a T1 and 35 ms round-trip time, you
would want connections to migrate to optimization gracefully, rather than risk
interruption with kickoff.
NOTE: Do not enable kickoff for in-path HP EFS WAN Accelerators that use auto-
discovery or if you do not have an HP EFS WAN Accelerator on the remote side of the
network.
Enable L4/PBR/WCCP Support on Interface <interface_name>. Check this box to
enable this feature on the named interface. External traffic redirection is only supported
on the first in-path interface. The interface name appears as wan0_0. The following
redirection methods are available:
• Layer-4 Switch. You enable Layer-4 switch support when you have multiple HP EFS
WAN Accelerators in your network, so that you can manage large bandwidth
requirements.
• Policy-Based Routing (PBR). PBR allows you to define policies to route packets
instead of relying on routing protocols. You enable PBR to redirect traffic that you
want optimized by an HP EFS WAN Accelerator that is not in the direct physical path
between the client and server.
• Web Cache Communication Protocol (WCCP). If your network design requires you
to use WCCP, a packet redirection mechanism directs packets to HP EFS WAN
Accelerators that are not in the direct physical path to ensure that they are optimized.
For detailed information about configuring Layer-4 switch, PBR, and WCCP
deployments, see the HP StorageWorks Enterprise File Services WAN Accelerator
Deployment Guide.
Enable Optimizations on Interface <interface_name>. Check this box to enable in-
path support for additional bypass cards. The interface names for the bypass cards are a
combination of the slot number and the port pairs (inpath<slot>_<pair>).
Out-of-Path Enable Out-of-Path Support. Check this box to enable out-of-path support. You can
enable out-of-path support for server-side appliances only.
