6.3 Spanning Tree
6.3.5.1

spanning-tree

Description
With this command, you configure the various properties of the spanning tree function:
● With the cost option, you configure the port costs used to calculate the lowest-cost path.
● With the disable option, you disable the interface for the spanning tree function.
● With the link-type option, you configure the connection status of the following network
segment. The following settings are possible:
– point-to-point – the interface communicates with precisely one network component
– shared - the interface is connected to more than one network component
● With the portfast option, you enable the PortFast function on the interface. The interface
is connected to an end device and can therefore ignore the waiting time before changing
to Forwarding mode.
● With the port-priority option, you configure the priority of the interface for negotiating
a spanning tree configuration.
