Description 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
function of QoS was introduced into VRP. 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 shutdown and
undo shutdown on the interface to have the function take effect.
So far, this command is supported only by Ethernet, serial, and BRI interfaces.
