token-number: The number of transmitted tokens, in the range 1 to 50.
Use the
qos qmtoken
Use the
undo qos qmtoken
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.
