R3303-HP HSR6800 Routers ACL and QoS Command Reference

114
Usage guidelines
This command is supported only on serial interfaces. After you configure this command on an interface,
you must execute the shutdown command and then the undo shutdown command on the interface to
have the feature take effect.
During FTP transmission, flow control provided by the upper layer protocol might invalidate the QoS
queuing configuration. The QoS token feature provides a flow control mechanism for underlying-layer
queues. This feature can control the number of packets sent to such queues based on the number of
tokens.
HP recommends that you set the token-number to 1 on an interface for FTP transmission.
Examples
# Set the number of QoS tokens to 1.
<Sysname> system-view
[Sysname] interface serial 2/0/1
[Sysname-Serial2/0/1] qos qmtoken 1
[Sysname-Serial2/0/1] shutdown
[Sysname-Serial2/0/1] undo shutdown
