# Monitoring Service Levels with Traffic Classes

#### Purpose

Display information about traffic classes.

#### Action

To display information about all traffic classes:

    host1#show traffic-class
                           fabric
    traffic       fabric   strict
    class         weight   priority
    -----------   ------   --------
    best-effort     8         no
    best-effort     8         no
    tc1             8         no
    tc2             8         no
    tc3             8         no
    tcs4            8        yes
    tcs5            8        yes

To display the number of times that a QoS profile references the traffic class:

    host1#show traffic-class brief
    traffic-class best-effort referenced 17 times in qos-profiles

To display a list of QoS profiles and traffic-class groups that reference the traffic class:

    host1#show traffic-class references
    traffic-class best-effort
      Referenced by QoS profiles:
        atm-default
        serial-default
        ethernet-default
        server-default
      Referenced by traffic class groups:
        None
