# Monitoring the QoS Profiles Attached to an Interface

#### Purpose

Display the QoS profiles in effect for and stacked above the specified interface. If no QoS profiles are attached to the interface or above the interface, the router displays the QoS profile that is in effect down the interface stack toward the port interface.

#### Action

To display the interface hierarchy for a specific interface:

    host1#show qos interface-hierarchy interface atm 11/0.1
    attachment@ atm-vc ATM11/0.1:
                    t-class interface rule    traffic    scheduler    queue
      qos profile    group    type    type     class      profile    profile
    --------------- ------- --------- ----- ----------- ------------ -------
    qp2@ATM11/0.1           atm-vc    node              default      default
    qp2@ATM11/0.1           atm-vp    node              default      default
    qp2@ATM11/0.1           atm-vc    queue best-effort default      default
    qp2@ATM11/0.1           atm-vc    queue tc5         default      default
    qp2@ATM11/0.1           atm-vc    queue tc6         default      default
    qp2@ATM11/0.1   g1      atm       group             strictShaper default
    qp2@ATM11/0.1   g1      atm-vc    node              default      default
    qp2@ATM11/0.1   g1      atm-vp    node              default      default
    qp2@ATM11/0.1   g1      atm-vc    queue tc1         default      default
    qp2@ATM11/0.1   g1      atm-vc    queue tc2         default      default
    qp2@ATM11/0.1   g2      atm-vp    node              default      default
    qp2@ATM11/0.1   g2      atm-vc    queue tc3         default      default
    qp2@ATM11/0.1   g2      atm-vc    queue tc4         default      default

To display the interface hierarchy using an L2TP session:

    host1#show qos interface-hierarchy l2tp-session session1

To display the interface hierarchy for a tunnel interface, specify the interface at the root of the scheduler hierarchy located on the tunnel-service interface or at the same hierarchy for LNS GRE tunnel traffic:

    host1#show qos interface-hierarchy tunnel-server 6/0

To display the interface hierarchy for an interface set:

    host1#show qos interface-hierarchy qos-interface-set gigEbusiness

To display the interface hierarchy for an interface superset:

    host1#show qos interface-hierarchy qos-interface-superset allservices

#### Meaning

Table 47 lists the show qos interface-hierarchy command output fields.
