Operation Command
Configure the port priority.
stp [ instance instance-id ] port priority priority
Restore the default port priority. undo stp [ instance instance-id ] port priority
You can configure the port priority with either of the earlier-mentioned measures. Upon
the change of port priority, MSTP will recalculate the port role and transit the state.
Generally, 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 according to actual
networking requirements.
By default, the priority of all the Ethernet ports is 128.
