4. Use the controls to complete the configuration, as described in the following table.

to their previous values.
Enabling
Quality of
Service You enable Quality of Service (QoS) in the Advanced Networking - QoS Classification
page.
You can configure QoS on HP EFS WAN Accelerators to control the prioritization of
different types of network traffic and to ensure that HP EFS WAN Accelerators give
certain network traffic (for instance, voice over IP) higher priority than other network
traffic.
Control Description
Add New Rule Type. Select one of the following rule types from the drop-down list:
• Auto. Allows built-in functionality to determine the response for peering requests
(performs the best peering possible).
• Accept. Accepts peering requests that match the source-destination-port pattern.
• Pass. Allows pass-through peering requests that match the source and destination port
pattern.
You can configure peering rules that apply to a single port or you can configure peering
rules that apply to a port label. A port label is a label that you assign to a set of ports so
that you can reduce the number of configuration rules in your system. For detailed
information about how to configure port labels, see
“Creating Port Labels” on page 113 .
Insert Rule At. Select start, end, or a rule number from the drop-down list.
HP EFS WAN Accelerators evaluate rules in numerical order starting with rule 1. If the
conditions set in the rule match, then the rule is applied, and the system moves on to the
next packet. If the conditions set in the rule do not match, the system consults the next
rule. For example, if the conditions of rule 1 do not match, rule 2 is consulted. If rule 2
matches the conditions, it is applied, and no further rules are consulted.
Source Subnet. Specify the IP address for the source network. Use the following format:
XXX.XXX.XXX.XXX/XX.
Destination Subnet. Specify the IP address for the destination subnet. Use the following
format: XXX.XXX.XXX.XXX/XX.
Port. Specify the destination port number, port label, or all. For detailed information on
port labels, see
“Creating Port Labels” on page 113 .
Peer IP. Specify the IP address for the peer to which TCP requests should spill over
when the HP EFS WAN Accelerator reaches its built-in capacity limit.
Description. Specify a description to help you identify the peering relationship.
Add Rule. Specify this option to add the rule to the list of rules for the profile.
Remove Selected Rules. To remove an entry, click the check box next to the and entry
and click Remove Selected Rules.
Move Rule. Use the Move Rule drop-down list boxes and button to change the order in
which rules are evaluated.
