View
Ethernet port view
Parameter
priority-level: Priority value of the port, ranging from 0 to 7.
Description
Use the priority command to configure the priority of the Ethernet port.
Use the undo priority command to restore the default priority of the Ethernet port.
By default, the priority of a port is 0.
If the switch receives a packet without VLAN tags, the switch will tag the packet with the
default VLAN of the port receiving the packet. In this case the switch assigns the port
priority of the port receiving the packet to the 802.1p priority of the VLAN tag in the
packet.
The switch does not perform the operation above if it receives a packet with VLAN tags.
Example
# Set the local precedence of Ethernet1/0/1 to 7.
