QoS Configuration 221
By default, the switch obtains local precedence and drop precedence according to
the default mapping values.
Configuring Default Local Precedence for a Port Perform the following
configuration in Ethernet interface view.
Configuring Traffic Policing
Traffic policing refers to the 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 802.1p priority values allocated according to the Local-precedence +
Conform-Level -> 802.1p priority mapping table. So you should configure these
two mapping tables or use their default values.
Perform the following configurations in Ethernet interface or VLAN view.
Restore the default values of CoS ->
Drop-precedence mapping table
