# 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

#### Meaning

Table 51 lists the related show interfaces command output fields.

Table 51: show interfaces Output Fields

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.
