Configuration example for traffic policing
Configure TP on the interface Ethernet1/0 to perform traffic control on the traffic
transmitted on the interface Ethernet1/0. The traffic should not exceed 1 Mbps
and the illegal packets will be dropped.
# Enter system view.
<Sysname> system-view
# Enter interface view.
[Sysname] interface ethernet1/0
# Configure traffic policing parameters.

The traffic shaping configuration falls into two types:
Configuring traffic shaping based on ACL: Set shaping parameters for the
■
traffic matching an ACL. Multiple shaping parameters can be set by using
different ACLs.

■
for all traffics.
Traffic shaping for software forwarding does not support IPv6.
