Modifying QoS
Marking
Descriptions You can modify the description of your QoS marking rules in the Advanced
Networking - QoS Marking Edit page.
Control Description
Add New Mappings Insert Rule At. Select start, end, or a rule number from the drop-down list. Specify an
ordered list of rules where each rule is the DSCP level used on the inner connection for
connections matching the source IP subnet, the destination IP subnet and, optionally, the
destination port fields.
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 network. Use the
following format: XXX.XXX.XXX.XXX/XX.
Port. Specify the port number or 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 .
For the MAPI data channel, specify port 7830 and the corresponding DSCP level.
For the FTP data channel, specify port 20 and the corresponding DSCP level. Setting
QoS for port 20 on the client-side HP EFS WAN Accelerator effects passive FTP, while
setting the QoS for port 20 on the server-side HP EFS WAN Accelerator effects port
active FTP.
DSCP. Specify the DSCP level (0-63). Specify a DSCP level to use instead of the
existing DSCP level. If you do not define a DSCP level, the HP EFS WAN Accelerator
uses the existing DSCP level.
IMPORTANT: If your connections already have a DSCP level and you do not define
one in the Management Console, the HP EFS WAN Accelerator uses the existing DSCP
level for the connection between the HP EFS WAN Accelerators. If you define a DSCP
level in the Management Console, the HP EFS WAN Accelerator overrides the existing
DSCP level and the value that you defined is applied.
Description. Specify a description of the QoS rule.
Add Rule. Click Add Rule to add a rule to the QoS rule list.
Remove Selected Rules. To remove an entry, click the check box next to the name and
click Remove Selected Rules.
