260 CHAPTER 8: STP OPERATION
Configuring in Ethernet Port View
Perform the following configuration in Ethernet port view.
For more about the commands, see the Switch 8800 Command Reference Guide.
After the change of port priority, MSTP will recalculate the port role and transit the
state. A smaller value represents a higher priority. If all the Ethernet ports of a
switch are configured with the same priority value, the priorities of the ports will
be differentiated by the index number. The change of Ethernet port priority will
lead to spanning tree recalculation. You can configure the port priority with actual
networking requirements.
By default, the priority of all the Ethernet ports is 128.
Configuring the Port
Connection with the
Point-to-Point Link
The point-to-point link directly connects two switches.
You can configure the port to connect or not connect with the point-to-point link
in the following ways.
