    Configuring CoS Schedulers (NSM Procedure)

    Using schedulers, you can assign attributes to queues and thereby provide congestion control for a particular class of traffic. These attributes include the amount of interface bandwidth, memory buffer size, transmit rate, and schedule priority.

    To configure CoS schedulers:

    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 schedulers.
    3. Click the Configuration tab. In the configuration tree expand Class of Service.
    4. Select Schedulers.
    5. Add or modify the 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.
