3. Use the controls to complete the configuration, as described in the following table.
4. Click Apply to apply your settings to the running configuration. (Apply your
settings to test a new configuration before committing it to memory.)
5. Click Save to write your settings to memory or click Reset to return the settings to
their previous value.
Setting In-Path
Interfaces
You modify the settings for the in-path interface in the Host Settings - Interface: In-
Path (LAN/WAN) page.
Control Description
IP Address Obtain IP address automatically. Select this button to automatically obtain the IP
address from a dynamic host configuration protocol (DHCP) server. (A Dynamic Host
Configuration Protocol (PP) server must be available so that the HP EFS WAN
Accelerator can request the IP address from it.)
IMPORTANT: The primary and in-path interfaces can share the same subnet. The
primary and auxiliary interfaces cannot share the same network subnet.
Specify IP Address Manually. Select this button if you do not use a DHCP server to set
the IP address. Specify the following settings:
• IP Address. Type an IP address in the text box.
• Subnet Mask. Type a subnet mask in the text box.
• Primary Gateway. Type primary gateway IP address in the text box. The primary
gateway must be in the same network as the primary interface. You must set the
primary gateway for in-path configurations.
Additional Interface Settings Speed. Select the speed from the drop-down list. The default value is Auto .
If your network routers or switches do not automatically negotiate the speed and duplex,
you must manually set the speed and duplex for the primary interface.
The speed and duplex must match (LAN and WAN) in an in-path configuration. If they
do not match you might have a large number of errors on the interface when it is in
bypass mode, because the switch and router are not set with the same speed settings.
Duplex. Select Auto, Full or Half from the drop-down list. The default value is Auto.
If your network routers or switches do not automatically negotiate the speed and duplex,
you must manually set the speed and duplex for the primary interface.
The speed and duplex must match (LAN and WAN) in an in-path configuration. If they
do not match you might have a large number of errors on the interface when it is in
bypass mode, because the switch and router are not set with the same duplex settings.
MTU. Type a Maximum Transmission Unit (MTU) value in the text box. The MTU is the
largest physical packet size, measured in Bytes, that a network can transmit. The default
value is 1500.
Bandwidth Limit Limit Optimized Bandwidth to. To limit optimized bandwidth, click this box and
specify a number of Kbps to set the limit.
The bandwidth limit applies only to the outgoing WAN interface and outgoing packets; it
does not apply to passed-through traffic. To limit a particular link to a certain bandwidth,
you must set the limit on the client and the server appliance. The default value is 1500.
