About 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.
About out-of-band traffic using DSCP marking
When two appliances 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, 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.
You use the management console to configure the separation of 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.
In the Application or Application Group text box, select Riverbed Control Traffic (Client) if the SteelHead being configured is a client-side SteelHead. Select Riverbed Control Traffic (Server) if the SteelHead being configured is a server-side SteelHead.
OOB packets are marked on the server-side appliance based on the value configured on the client-side appliance if a rule isn’t explicitly configured on the server-side.
Under Outbound DSCP, select a DSCP marking value or a ToS IP value from the drop-down list.
