# Monitoring the QoS Configuration of ATM Interfaces

#### Purpose

Display ATM port queuing mode and QoS shaping mode status for a specific ATM interface.

#### Action

To display the QoS configuration on an ATM interface:

    host1# show interfaces atm 2/0
    ATM Interface 2/0 is up, line protocol is disabled
    AAL5 operational status:       up
          time since last status change: 01:08:32
    ATM operational status:        up
          time since last status change: 01:08:32
    .
    .
    .....
    InPackets:        0
    InBytes:          0
    InCells:          0
    OutPackets:       7803262
    OutBytes:         7803262000
    OutCells:         163868502
    InErrors:         0
    OutErrors:        0
    InPacketDiscards: 0
    InByteDiscards:   0
    InCellErrors:     0
    Administrative qos-shaping-mode: frame
    Operational qos-shaping-mode: frame
    Administrative qos-mode-port: none
    Operational qos-mode-port: none
    Attached QoS profile: shaping

#### Meaning

Table 49 lists the related show interfaces atm command output fields.

Table 49: show interfaces atm Output Fields

Field Name | Field Description
--- | ---
Administrative qos-mode-port | Per-port queuing mode status: disabled, low-latency, low-cdv, none
Operational qos-mode-port | Per-port queuing mode status: disabled, low-latency, low-cdv, none
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 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 values configured for the qos-shaping-mode command or the qos-port-mode command. For more information, see Per-Packet Queuing on the SAR Scheduler Overview. disabled—Shaping mode is configured but disabled. frame—Default shaping mode for shaping and policing rates. Reports 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 VC, and the attachment is at the ATM AAL5 interface, the ATM AAL5 interface attachment is displayed.
