Priority:
 
Decide which port should be blocked by setting its priority as the lowest. Enter a 
number between 0 and 240.  
The value of priority must be the multiple of 16. 
Admin P2P:
 
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 
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. 
Admin Non STP:
 
The port includes the STP mathematic calculation.   
• 
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.
