Description
Using mirrored-to command, you can enable ACL traffic identification and perform
traffic mirror. Using undo mirrored-to command, you can cancel traffic mirror.
This command is used for mirroring the traffic matching the specified ACL (whose
action is permit). The observing port cannot be a Trunk port or aggregated port.
This command only supports one observing port. When you use the traffic mirror for
the first time, you have to designate the observing port.
For the related command, see display qos-global mirrored-to.

Parameter
priority-level: Specifies the priority level of the port, ranging from 0 to 7.
Description
Using priority command, you can configure the priority of Ethernet port. Using undo
priority command, you can restore the default port priority.
By default, the priority level of the port is 0 and switch replaces the 802.1p priority
carried by a packet with the port priority.
Every port of Ethernet switch supports four packet egress queues. The switch puts the
packets into different egress queues according to their priorities.
You can set a priority for a port and replace the 802.1p priority carried in the packet
with it. After transmitting a packet, the switch will replace the packet 802.1p priority
with the priority of the received port, according to which the packet will be put into the
corresponding egress queue.
