52 2 - C ONFIGURING THE HP EFS WAN A CCELERATOR
8. Select the speed in the WAN Speed drop-down list to set the speed for the in-path
WAN port. The default value is Auto.
9. Select Auto, Full, or Half in the Duplex drop-down list to set the duplex speed for
the in-path WAN port. The default value is Auto.
10. Type an MTU value in the MTU text box. The MTU is the largest physical packet
size, measured in Bytes, that a network can transmit. The MTU is set once on the
in-path interface, it propagates automatically to the LAN and the WAN. The
default value is 1500.
11. Optionally, if you have enabled VLAN tagging, type the VLAN tag ID in the
VLAN Tag ID text box so that all packets originating from that HP EFS WAN
Accelerator are tagged with this ID. The VLAN tag ID can be the same value or a
different value than the VLAN tag used on the client. A zero (0) value specifies
non-tagged (or native) VLAN.
NOTE: When the HP EFS WAN Accelerator communicates with a client or a server it uses the
same VLAN tag as the client or the server. If the HP EFS WAN Accelerator cannot determine
which VLAN the client or server is in, it uses its own VLAN until it is able to determine that
information.
12. Under Bandwidth Limit, click Limit Optimized Bandwidth Utilization to and
type a value in the kbps text box to restrict the total optimized traffic to a specific
bandwidth limit. The default value is 1500.
IMPORTANT: The bandwidth limit applies only to the outgoing WAN interface and outgoing
packets, not to passed through traffic. To limit a particular link to a certain bandwidth, you must
to set the limit on the client and the server HP EFS WAN Accelerator.
13. Click Apply to apply your settings to the running configuration. (Apply your
settings to test a new configuration before committing it to memory.)
14. Click Save to write your settings to memory or click Reset to return the settings to
their previous values.
Setting
Auxiliary
Interfaces
Optionally, you can set an auxiliary interface if your network configuration has a
dedicated management subnet in the Setup: Host Settings - Interface: AUX page. For
example, if your network has an auxiliary interface that connects and passes packets
between the HP EFS WAN Accelerator and a different network, such as one purely for
device management.
If your network routers do not automatically negotiate the speed and duplex, you must
manually set the speed and duplex for the auxiliary interface.
