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.
