Interface configuration (physical port and port-channel interfaces)
This feature is used in a service-provider environment where the network
administrator needs to prevent a low speed port becoming a root port for the
local bridge networks. This configuration will take effect on all the spanning-tree
versions.
This example shows how to configure eth3.1 to prevent if from becoming a root
port.
Verify the settings by entering the show spanning-tree interface command.
