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 1 lists the related show interfaces command output fields.

Table 1: 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.

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.
