Traffic Shaping Configuration 835
Figure 249 TS diagram
For example, Switch A sends packets to Switch B. Switch B implements TP on
those packets, and directly drops exceeding traffic.
To reduce unnecessary packet drop, GTS can be applied to the packets on the
egress interface of Switch A. The packets beyond the traffic specifications of GTS
are stored in Switch A. While sending the next set of packets, GTS takes out those
packets from buffer queues and send them. Thus, all the packets sent to Switch B
accord with the traffic specification of Switch B.

■ Traffic shaping cannot be configured on ports with even port numbers on the
3C17526 module, and traffic shaping configured on a port with an odd port
number takes effect on the incoming packets of both the port with the odd
port number and the port with the even port number (the odd port number
plus one).
■ Traffic shaping is not available to POS interfaces.

Shaping
Traffic shaping includes the following two types:
■ Queue-based traffic shaping: set traffic shaping parameters for packets in a
queue.
■ Traffic shaping applicable to all the traffic: set traffic shaping parameters for all
the traffic.
Configuring queue-based traffic shaping
Follow these steps to configure queue-based traffic shaping:
