Configuring CoS and Applying Scheduler Maps

You associate the schedulers with forwarding classes by means of scheduler maps. You can then associate each scheduler map with an interface, thereby configuring the queues and packet schedulers that operate according to this mapping.

To configure CoS and apply scheduler maps:

  1. In the navigation tree, select Device Manager > Devices.
  2. Click the Device Tree tab, and then double-click the device for which you want to configure CoS and apply scheduler maps.
  3. Click the Configuration tab. In the configuration tree expand Class of Service.
  4. Select Scheduler Maps.
  5. Add or modify settings as specified in Table 1.
  6. Click one:
    • OK—Saves the changes.
    • Cancel—Cancels the modifications.

Note: After you make changes to a device configuration, you must push that updated device configuration to the physical security device for those changes to take effect. You can update multiple devices at one time. See the Network and Security Manager Administration Guide for more information.

  4. Click OK.

Apply the scheduler map to an interface.
  1. Select Interfaces > Interface and click Add new entry.
  2. In the Interface name box, type the name of the interface—for example, ge-0/0/0.
  3. Select Unit and click Add new entry.
  4. In the Unit name box, select the logical interface unit number—for example, 0.
