	Decide which port should be blocked by setting its priority as the lowest. Enter a
Priority:	number between 0 and 240.
	The value of priority must be the multiple of 16.
	The rapid state transitions possible within RSTP are dependent upon whether the
	port concerned can only be connected to exactly another bridge (i.e. it is served
	by a point-to-point LAN segment), or can be connected to two or more bridges
	(i.e. it is served by a shared medium LAN segment). This function allows the P2P
Admin P2P:	status of the link to be manipulated administratively.
	• YES means the port is regarded as a point-to-point link.
	• NO means the port is regarded as a shared link.
	• AUTO means the link type is determined by the auto-negotiation between
	the two peers.
Admin Edge:	The port directly connected to end stations won’t create bridging loop in the
	network. To configure the port as an edge port, set the port to “YES” status.
	The port includes the STP mathematic calculation.
Admin Non STP:	• YES is not including STP mathematic calculation.
	• NO is including the STP mathematic calculation.

Path cost “0” is used to indicate auto-configuration mode. When the short path cost method is selected and the default path cost recommended by the IEEE 8021w standard exceeds 65,535, the default is set to 65,535.

By default, the system automatically detects the speed and duplex mode used on each port, and configures the path cost according to the values shown below.

Port Type	IEEE 802.1D-1998	IEEE 802.1w-2001
Ethernet	50-600	200,000-20,000,000
Fast Ethernet	10-60	20,000-2,000,000
Gigabit Ethernet	3-10	2,000-200,000
