Configuring QoS tokens

Because the upper layer protocol TCP provides traffic control, CQ and WFQ might become invalid

during FTP transmission. QoS tokens can solve this problem. The token feature of QoS provides a flow

control mechanism for underlying-layer queues. This feature can control the number of packets sent to the

interface underlying-layer queues based on the number of tokens.

HP recommends that you set the token number to 1 on an interface for FTP transmission.

If the upper layer protocol, UDP for example, does not provide flow control, do not use the QoS token

function to improve data transmission efficiency.

Configuration procedure

To configure QoS tokens:

Ste

Command

Remarks

1. Enter system view.

system-view N/A

2. Enter interface view.

interface interface-type

interface-number

Applicable to only serial interfaces.

3. Specify the number of

QoS tokens.

qos qmtoken token-number By default, the QoS token feature is disabled.

4. Shut down the interface.

shutdown

Re-enable the interface by using the shutdown

command and then the undo shutdown

command to make the QoS token feature take

effect.

5. Bring up the interface.

undo shutdown N/A

QoS token configuration example

Network requirements

Specify the number of QoS tokens on interface Serial 1/1/1.

Configuration procedure

# Enter system view.

<Sysname> system-view

# Enter interface view.

[Sysname] interface serial 1/1/1

# Set the number of QoS tokens to 1, and re-enable the interface to make the configuration take effect.
