qos profile class
Configures the QoS class for a profile.
Syntax
[no] qos profile <name> class <class-name> [parent <class-name>]
Parameters
<name>
QoS profile name.
<class-name>
QoS class name. The QoS class indicates how delay-sensitive a traffic class is to the QoS scheduler. Select a class for the profile from the following (highest priority to lowest):
•  Real Time - Specifies the 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.
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.
parent <class-name>
Specifies the parent class name for the configured class.
You cannot change the parent class for an existing child class. To remove the parent class, you must delete all rules for the corresponding child classes first.
Usage
A QoS profile contains one or more classes. Classes model the network requirements for applications that exhibit similar characteristics and have similar requirements: minimum bandwidth, maximum bandwidth, and latency priority. For example, the real-time class contains voice and video traffic.
Specifying the parent for a child class enables the QoS hierarchy. The class will inherit the parent’s definitions. For example, if the parent class has a business priority, and its child has a real-time priority, the child will inherit the business priority from its parent, and will use a real-time priority only with respect to its siblings. For more information, see the SteelHead Management Console User’s Guide and the SteelHead Deployment Guide.
