spanning-tree enable/disable
The spanning-tree
enables/disables the Spanning Tree option.
The Spanning Tree algorithm dynamically creates a tree through the network used to
efficiently direct packets to their destinations. When STP is enabled, the unit acts as a node in
the tree. When STP is disabled, you can still use the other commands to set the STP
configuration. These settings are preserved when STP is enabled. To disable the spanning
tree you can also use the no form of the command.
By default, STP is disabled.
Command Syntax
device-name(cfg protocol)#spanning-tree {enable|disable}
device-name(cfg protocol)#no spanning-tree
