    Configuring a Classifier Profile for 3G and 4G Networks

    A classifier profile defines the QoS classification for a MobileNext Broadband Gateway configured as a gateway GPRS support node/Packet Data Network Gateway (GGSN/P-GW). You configure the traffic classes and QoS Class Identifier (QCI) values to define the packet-forwarding treatment for bearers. Each traffic class and QCI is associated with priority, delay, and packet loss values.

    To configure a classifier profile to map each QCI value to a forwarding class and packet loss priority:

    1. Specify a name for the classifier profile.
      [edit unified-edge cos-cac]user@host# edit classifier-profiles classifier-profile-1
    2. Configure each traffic class in the classifier profile based on the degree to which typical services representing a specific traffic class are delay sensitive:
      1. Configure the conversational traffic class.
        [edit unified-edge cos-cac classifier-profiles classifier-profile-1]user@host# set traffic-class conversational user@host# set forwarding-class efuser@host# set loss-priority low
      2. Configure the streaming traffic class.
        [edit unified-edge cos-cac classifier-profiles classifier-profile-1]user@host# set traffic-class streaming user@host# set forwarding-class af2user@host# set loss-priority low
      3. Configure the interactive traffic class.
        [edit unified-edge cos-cac classifier-profiles classifier-profile-1]user@host# set traffic-class interactive user@host# set traffic-handling-priority 2user@host# set forwarding-class af3user@host# set loss-priority low
      4. Configure the background traffic class.
        [edit unified-edge cos-cac classifier-profiles classifier-profile-1]user@host# set traffic-class background user@host# set forwarding-class beuser@host# set loss-priority high
    3. Configure the QCI values and the associated QoS characteristics based on traffic requirements:
      1. Configure a QCI value and the associated forwarding class and loss priority for IP Multimedia Subsystem (IMS) signaling traffic.
        [edit unified-edge cos-cac classifier-profiles classifier-profile-1]user@host# set qos-class-identifier 5user@host# set forwarding-class af2user@host# set loss-priority low
      2. Configure a QCI value and the associated forwarding class and loss priority for video (buffered streaming) traffic.
        [edit unified-edge cos-cac classifier-profiles classifier-profile-1]user@host# set qos-class-identifier 6user@host# set forwarding-class af2user@host# set loss-priority low
      3. Configure a QCI value and the associated forwarding class and loss priority for voice, video (live streaming), and interactive gaming traffic.
        [edit unified-edge cos-cac classifier-profiles classifier-profile-1]user@host# set qos-class-identifier 7user@host# set forwarding-class af3user@host# set loss-priority low
      4. Configure a QCI value and the associated forwarding class and loss priority for background traffic.
        [edit unified-edge cos-cac classifier-profiles classifier-profile-1]user@host# set qos-class-identifier 8user@host# set forwarding-class beuser@host# set loss-priority low
