If IEEE802.1p priority mode is configured, when a switch port receives an untagged
frame (a frame without priority tag), the port's default priority tag will be inserted into
the frame before any other process.

In IEEE802.1p priority mode, all packets are classified into four priority classes (lowest,
lower, higher and highest) according to the embedded priority tag. If an untagged
frame is received, the default priority tag of the port will be attached.

Port mirroring monitors and mirrors network traffic by forwarding copies of incoming
and outgoing packets from one port to a monitoring port. Port mirroring enables switch
performs monitoring.
Network administrators can configure port mirroring by selecting a specific port from
which to copy all packets, and other ports to which the packets copied.

The virtual cable test feature uses Time Domain Reflectometry (TDR) to test the
quality of the cables connected to the port. Some of the possible problems then can
be diagnosed include opens, shorts, cable impedance mismatch, bad connectors,
termination mismatch, and bad magnetics. It can also test the distance to the problem
location, with the precision of ±1 meter.
