Table 17 Configure the Port Priority
Operation
Configure the port priority.
Restore the default port priority.
For more about the commands, see the Switch 7700 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.
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.
