Function
Enables spanning-tree functionality. To disable spanning-tree
functionality, use the no form of this command.
configuration, use the no form of this command.
Configures the spanning-tree bridge forward time, which is the
amount of time a port remains in the listening and learning states
before entering the forwarding state. To return to the default
configuration, use the no form of this command.
Configures the spanning tree bridge hello time, which is how often
the device broadcasts hello messages to other devices.To return
to the default configuration, use the no form of this command.t
Configures the spanning tree bridge maximum age. To return to
the default configuration, use the no form of this command.
Configures the spanning tree priority of the device. The priority
value is used to determine which bridge is elected as the root
bridge. To return to the default configuration, use the no form of
this command.
Disables spanning tree on a specific port. To enable spanning tree
on a port, use the no form of this command.
Configures the spanning tree path cost for a port. To return to the
default configuration, use the no form of this command.
Configures port priority. To return to the default configuration, use
the no form of this command.
Enables PortFast mode. In PortFast mode, the interface is
immediately put into the forwarding state upon linkup without
waiting for the standard forward time delay. To disable PortFast
mode, use the no form of this command.
Overrides the default link-type setting determined by the duplex
mode of the port and enables Rapid Spanning Tree Protocol
(RSTP) transitions to the forwarding state. To return to the default
configuration, use the no form of this command.
Sets the default path cost method. To return to the default
configuration, use the no form of this command.
globally or on a single interface. To return to the default
configuration, use the no form of this command.
Restarts the protocol migration process (forces renegotiation with
neighboring devices) on all interfaces or on a specified interface.
Configures the device priority for the specified spanning-tree
instance. To return to the default configuration, use the no form of
this command.
