Per Port Configuration
Select the port you want to configure. You will see the current settings and status of the selected
port.
Path Cost : this value is the cost of the path to the other bridge from this transmitting bridge at the
specified port. Enter a number between 1 and 200000000.
Priority : this is the value that decides which port should be blocked by priority in LAN. Enter a
value between 0 and 240. The value of priority must be multiples of 16.
Admin P2P : some of the rapid state transactions that are possible within RSTP depend upon
whether the port concerned can only be connected to only on other 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.
True means P2P is enabled. False means P2P is disabled.
Admin Edge : the port directly connected to end stations cannot create a bridging loop in the
network. To configure the port as an edge port, set the port to True status.
Admin Non Stp : the status shown here indicates whether this port includes the STP mathematic
calculation. True means that this port does not include STP mathematic calculation. False
means that this port includes the STP mathematic calculation.
Once you finish configuring the settings, click on Apply to save the configuration.
Note: Remember to click on the Save Configuration button to save your settings. Otherwise the
settings you made will be gone when the JetNet is powered off.
Super Ring
Super Ring technology provides a faster redundant recovery than Spanning Tree topology does.
How Super Ring works is similar to STP or RSTP, but the algorithm is not exactly the same.
In a Super Ring topology, every JetNet should enable the Super Ring function, and assign 2
member ports in this ring. Only one JetNet in the Super Ring group would be set as a backup
switch, and one of its 2 member ports would be blocked, which is called the backup port. The
other port is called the working port. Other JetNets are called working switches, and their 2
member ports are also called working ports. When the network connection fails, the backup port
will automatically become a working port to recover the failure
You can use the DIP switches to configure one of the JetNets to be the ring master or slave. The
ring master has the rights to negotiate and place commands to other JetNets in the Super Ring
group. When the JetNet is set to be the ring master, the Super Ring configuration interface will
