BRIDGE PARAMETERS

To read the RSTP bridge parameters from the board,
1. From the main window click the device address to select the device. The RSTP Configuration window
appears and the default tab is Bridge Parameters.
2. Click the Get RSTP Parameters button. This displays all the RSTP bridge parameters from the Ethernet
board.
3. To modify the RSTP parameters, enter the values and click Set RSTP Parameters.
4. To restore the default values, click Restore Default and click Set RSTP Parameters.
The grayed parameters are read-only and cannot be modified.
Note:
When assigning the bridge priority, make sure the root of the network is the Ethernet switch, not the IEDs. This reduces the
number of hops to reach all devices in the network. Also make sure the priority values for all IEDs are higher than that of the
switch.
