    Monitoring the QoS Configuration of Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet Interfaces

    Purpose

    Display information about the QoS configuration for a specific Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface.

    Action

    To display the QoS configuration for a Fast Ethernet interface:

    host1#show interfaces fastEthernet 6/0
    GigEthernet6/0 is Up, Administrative status is Up
    Hardware is Intel 21440, address is 0090.1a40.5508
    MAU is 100BASE-TX
    MTU: Operational 1522, Administrative 1522
    Duplex Mode: Operational Full Duplex, Administrative Auto Negotiate
    Speed: Operational 100 Mbps, Administrative Auto Negotiate
    5 minute input rate 0 bits/sec, 0 packets/sec
    5 minute output rate 0 bits/sec, 0 packets/sec
    In: Bytes 0, Unicast 0
    Multicast 0, Broadcast 0
    Errors 0, Discards 0, Mac Errors 0, Alignment 0
    CRC 0, Too Longs 0, Symbol Errors 0
    Out: Bytes 64, Unicast 0
    Multicast 0, Broadcast 1
    Errors 0, Discards 0, Mac Errors 0, Deferred 0, No Carrier 0
    Collisions: Single 0, Multiple 0, Late 0, Excessive 0
    Administrative qos-shaping-mode: cell
    Operational qos-shaping-mode: cell
    Attached QoS profile: ss

    To display the QoS configuration for a Gigabit Ethernet interface:

    host1#show interfaces gigabitEthernet 2/0
    

    To display the QoS configuration for a 10-Gigabit Ethernet interface:

    host1#show interfaces tenGigabitEthernet 5/0/0

    Field Name

    Field Description

    Administrative qos-shaping-mode

    Configured shaping mode for the interface:

    • disabled—Shaping mode is configured but disabled.
    • frame—Default shaping mode for shaping and policing rates. Reports QoS statistics such as transmitted bytes and dropped bytes based on bytes within frames.
    • cell—Shaping mode for shaping and policing rates is cell-based; resulting traffic stream conforms exactly to the policing rates configured in downstream devices. Reports statistics in bytes within cells and also accounts for cell encapsulation and padding overhead.
    • none—Shaping mode is not configured.

    Operational qos-shaping-mode

    Actual shaping mode for the interface. The router determines the operational shaping mode based on the value configured using the qos-shaping-mode command. For more information, see QoS Shaping Mode for Ethernet Interfaces Overview.

    • disabled—Shaping mode is configured but disabled.
    • frame—Default shaping mode for shaping and policing rates. Reports QoS statistics such as transmitted bytes and dropped bytes based on bytes within frames.
    • cell—Shaping mode for shaping and policing rates is cell-based; resulting traffic stream conforms exactly to the policing rates configured in downstream devices. Reports statistics in bytes within cells and also accounts for cell encapsulation and padding overhead.
    • none—Shaping mode is not configured.

    Attached QoS profile

    QoS profile attachment at or below the displayed interface. For example, if the interface being displayed is a VLAN subinterface, and the attachment is at the Gigabit Ethernet interface, the Gigabit Ethernet attachment is displayed.
