2-5
The port of Ethernet Switch supports 8 priority levels. You can configure the port priority
at your requirements.
priority-level
ranges from 0 to 7.
By default, the port priority is 0 and switch replaces the priority carried by a packet with
the port priority.
2.2.2 Configuring Trust Packet Priority
The switch will tag the packet using the VLAN the received port belong to if the packet
has no VLAN tag. Meanwhile the system uses the port priority as the packet the 802.1p
priority when tag the packet. If the packet has VLAN tag, the system will not re-tag the
packet. User can configure system trusting the packet 802.1p priority and not replacing
the 802.1p priorities carried by the packets with the port priority.
Perform the following configuration in Ethernet port view.

2.2.3 Traffic Policing
Traffic policing is the flow-based traffic limit. It takes corresponding actions to deal with
the flow at exceeding speed, such as discarding or lowering the priority.
You can use the following command to configure the traffic policing.
Perform the following configuration in Ethernet port view.
