Modifying QoS Profiles
You can modify the profile name, QoS class properties, and QoS rule properties in the Networking > Network Services: QoS Profiles page. You can rename a profile name, class, or rule seamlessly without the need to manually update the associated resources. For example, if you rename a profile associated with a site, the system updates the profile name and the profile name within the site definition automatically.
For details on creating a profile, see
Creating QoS Profiles.
To modify a QoS profile name, class, or rule
1. Choose Networking > Network Services: Quality of Service to display the Quality of Service page.
2. Under QoS Profiles, click Edit next to the profile name to display the QoS Profile page.
3. Perform any of these tasks (in any order):
• Rename the profile.
• Click Edit next to the class name and change its properties.
• Select a rule and change its properties.
4. Click Save to Disk to save your settings permanently.
Classifying and Prioritizing OOB Traffic Using DSCP Marking
When two SteelHeads see each other for the first time, either through autodiscovery or a fixed-target rule, they set up an Out-Of-Band (OOB) splice. This is a control TCP session between the two SteelHeads that the system uses to test the connectivity between the two appliances.
After the setup of the OOB splice, the two SteelHeads exchange information about each other such as the hostname, licensing information, RiOS versions, capabilities, and so on. This information is included in the Riverbed control channel traffic.
By default, the control channel traffic isn’t marked with a DSCP value. By marking the control channel traffic with a DSCP or ToS IP value, you can prevent dropped packets and other undesired effects on a lossy or congested network link.
In RiOS 9.0 and earlier, a CLI command enables the global DSCP setting to tag inner channel setup packets or OOB packets with a DSCP value. RiOS 9.1 and later provides a way to separate the inner channel setup packets from the OOB packets and mark the OOB control channel traffic with a unique DSCP value.
Before marking OOB traffic with a DSCP value, ensure that the global DSCP setting isn’t in use. Global DSCP marking includes both inner channel setup packets and OOB control channel traffic. This procedure separates the OOB traffic from the inner channel setup traffic. For details on disabling global DSCP marking, see the [no] qos dscp-marking enable command in the Riverbed Command-Line Interface Reference Manual.
To classify OOB traffic with a DSCP marking
1. Choose Networking > Network Services: Quality of Service to display the Quality of Service page.
2. Under QoS Profiles, click Edit next to the profile name to display the QoS Profile Details page.
3. Under QoS Rules, select Add a Rule.
4. From the Application or Application Group drop-down list, select Riverbed Control Traffic (Client) if the SteelHead being configured is a client-side SteelHead. Select Riverbed Control Traffic (Server) if a the SteelHead being configured is a server-side SteelHead.
OOB packets are marked on the server-side SteelHead based on the value configured on client-side SteelHead if a rule isn’t explicitly configured on the server-side SteelHead.
5. Under Outbound DSCP, select a DSCP marking value or a ToS IP value from the drop-down list.
6. Click Save to Disk to save your settings permanently.
The new QoS rule appears in the QoS Rules table.
