HP StorageWorks Enterprise File Services WAN Accelerator 3.0.4 Command-Line Interface reference manual (AG421-96004, March 2007)

174 4 - CONFIGURATION-MODE COMMANDS
Syntax [no] qos dscp move-rule <rulenum>
Parameters
Example
minna (config) # qos dscp move-rule rulenum 3
minna (config) #
qos dscp rule
Description Maps a service port to a Quality of Service (QoS) Differentiated Services Code Point
(DSCP) level based on the source IP subnet, the destination IP subnet, destination
port, and rule number. Specifying the destination IP address enables you to apply
different DSCP levels to different servers.
The no qos rule rulenum <rulenum> command disables the QoS rule.
You specify an ordered list of rules where each rule is the DSCP level to use on the
inner connection for connections matching the source IP subnet, the destination IP
subnet and, optionally, the destination port fields.
After you map a service port and a DSCP level, every packet using that service port
has the DSCP field set to that value in the forward and backward direction. On the
WAN HP EFS WAN Accelerator, you can configure a network router or a traffic
shaper to prioritize packets according to the value in the DSCP field before they are
sent across the WAN.
If you have already defined a DSCP level and you do not define one in the HP EFS
WAN Accelerator Manager, 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 HP EFS WAN Accelerator Manager, the HP EFS WAN Accelerator
overrides the existing DSCP level and the value that you defined is applied.
TIP: To configure QoS mapping for the FTP data channel, specify port 20 and the
corresponding DSCP level. To configure QoS mapping for the MAPI data channel, specify port
7830 and the corresponding DSCP level.
Syntax [no] qos dscp rule src <source IP> dest <destination IP> [dest-port <port>] dscp
<level> rulenum <rulenum>
Parameters
<rulenum> Specifies the order in which rules are processed.
<source IP> Specifies the source IP subnet. You can use wild cards in this field.
<destination IP> Specifies the destination IP subnet. You can use wild cards in this
field.
