QOS TOKEN CONFIGURATION
COMMANDS
qos qmtoken
Syntax qos qmtoken token-number
undo qos qmtoken
View Interface view
Parameters token-number: The number of transmitted tokens, in the range 1 to 50.
Description Use the
qos qmtoken command to configure the number of transmitted tokens.
Use the undo qos qmtoken command to disable the token transmission
function of QoS.
By default, the function of QoS is disabled.
During an FTP transfer, flow control provided by the upper layer protocol can
invalidate the configuration of QoS queuing. To resolve this problem, the token
transmission function of QoS was introduced. This function provides a flow control
mechanism at the underlying-layer queuing level. It can control the number of
packets sent to the underlying interface queues based on the number of tokens.
If FTP applies, you are recommended to set the number of tokens sent by an
interface to 1.

■ After you configure this command on an interface, you must perform

effect.
■ So far, this command is supported only by Ethernet, serial, and BRI interfaces.
