Priority (0-7)
This parameter is specified if you want to re-write the 802.1p default priority previously
set in the Switch, which is used to determine the CoS queue to which packets are
forwarded to. Once this field is specified, packets accepted by the Switch that match this
priority are forwarded to the CoS queue specified previously by the user.
For more information on priority queues, CoS queues and mapping for 802.1p, see the
QoS section of this manual.

its original value before being forwarded by the Switch.
