Configuring default local precedencePerform the following configurations in Ethernet port view.Table 2-3 Configure default local precedence for portOperation CommandConfigure default local precedence for a port priority priority-levelRestore the default local precedence for a port undo priority2.2.2 Configuring Traffic PolicingTraffic 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 orre-defining their priority levels.In the traffic supervision action, the switch uses the service parameters allocatedaccording to the DSCP + Conform-Level —> Service parameter mapping table and theEXP + Conform-Level —> Service parameter mapping table and the 802.1p priorityvalues allocated according to the Local-precedence+Conform-Level —> 802.1p prioritymapping table. So you should configure these three mapping tables or use their defaultvalues.I. Configuring mapping tablesPerform the following configurations in the specified views.
