33.3.2 Configuring Traffic Policing
Traffic policing refers to rate limit based on traffic. If the traffic threshold is exceeded,
corresponding measures will be taken, for example, dropping the excessive packets or
re-defining their priority levels.
In the traffic supervision action, the switch uses the service parameters allocated
according to the DSCP + Conform-Level —> Service parameter mapping table and the
EXP + Conform-Level —> Service parameter mapping table and the 802.1p priority
values allocated according to the Local-precedence + Conform-Level —> 802.1p
priority mapping table. So you should configure these three mapping tables or use their
default values.
I. Configuring mapping tables
Perform the following configurations in the specified views.
