    Select the action to be performed. The actions that can be performed are:

    • Add new Rule

    • Edit “priority”

    • Edit “best_effort”

    NameEnter the name of the class of service and its associated priority queue.

    Priority Class

    Choose a class of service from the drop-down list:

    • Best Effort —Default. All unmarked traffic is assigned to this class. This traffic is also the first to be dropped during times of congestion. Examples of best effort traffic include web, email, SNMP, and so on.

    • Assured Forwarding / IP Precedence (1 to 4)— For applications that require better reliability than the best-effort service. There are four Assured Forwarding classes of service:

       • AF1x/IP1

       • AF2x/IP2

       • AF3x/IP3

       • AF4x/IP14

    • Expedited Forwarding / IP Precedence 5— Provides low-loss, low-latency, low-jitter, and guaranteed bandwidth. For real-time voice traffic:

    • IP Precedence 6 and 7:

       • IP6

       • IP7

    LLQ

    Designates traffic as LLQ. LLQ traffic is strictly prioritized and all LLQ traffic is transmitted before any GRED traffic is sent. Refer to Set GRED/LLQ Configuration Rules.

    Bandwidth Percentage

    Specifies the guaranteed percentage of bandwidth for the associated class during times of congestion.

    Note: The sum of bandwidth percentages for all configured classes cannot exceed 100 percent.
