qos profile rule
Modifies a rule for a QoS profile.
Syntax
[no] qos profile <name> rule application <app-name> [class <class-name>] [dscp <value>] [position <position>]
Parameters
<name>
QoS profile name.
application <app-name>
Specifies the name of the application. Enter ? at the system prompt to view a list of more than 1100 available applications.
class <class-name>
Configures the class name for traffic matching this rule.
The QoS class indicates how delay-sensitive a traffic class is to the QoS scheduler. Select a service class for the profile from the following (highest priority to lowest):
•  Real Time - Specifies real-time traffic class. Give this value to your highest priority traffic; for example, VoIP, or video conferencing.
•  Interactive - Specifies an interactive traffic class: for example, Citrix, RDP, telnet and ssh.
•  Business Critical - Specifies the business critical traffic class: for example, Thick Client Applications, ERPs, and CRMs.
•  Normal - Specifies a normal priority traffic class: for example, Internet browsing, file sharing, and email.
•  Low Priority - Specifies a low priority traffic class: for example, FTP, backup, replication, other high-throughput data transfers, and recreational applications such as audio file sharing.
•  Best Effort - Specifies the lowest priority.
•  default - Uses whichever class is currently set for the default rule. By default, this is Low Priority. You can change it by modifying the default rule.
These are minimum service class guarantees; if better service is available, it is provided: for example, if a class is specified as low priority and the higher priority classes are not active, then the low priority class receives the highest possible available priority for the current traffic conditions. This parameter controls the priority of the class relative to the other classes.
dscp <value>
Specifies the DSCP value. The DSCP values are 0-63, preserve, or inherit (inherit from class). Preserve means that the DSCP level or IP ToS value found on the pass-through traffic is unchanged when it passes through the SteelHead.
position <position>
Specifies the position in which the rule is consulted: 1 - <maximum position>.
Usage
This command adds, edits, or deletes a rule from a QoS profile. You can create multiple QoS rules for a profile and these rules are followed in the configured order. SteelHeads support up to 2000 rules and up to 500 sites.
