Configuring CoS Forwarding Classes (NSM Procedure)

Forwarding classes allow you to group packets for transmission. Based on forwarding classes, you assign packets to output queues.

By default, four categories of forwarding classes are defined: best effort, assured forwarding, expedited forwarding, and network control.

Note: EX-series switches support up to 16 forwarding classes.

To configure CoS forwarding classes:

  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 forwarding classes.
  3. Click the Configuration tab. In the configuration tree, expand Class of Service.
  4. Select Forwarding Classes.
  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.
