Configuring Spanning Tree Network Ports on Specified Interfaces
• spanning-tree port type network—This command explicitly configures the port as a network port. If
• spanning-tree port type normal —This command explicitly configures the port as a normal spanning
• no spanning-tree port type—This command implicitly enables the port as a spanning tree network
A port connected to a Layer 2 host that is configured as a network port automatically moves into the
Note
blocking state.
Before You Begin
• Ensure that you are in the correct VDC (or enter the switchto vdc command).
• Ensure that STP is configured.
• Ensure that you are configuring the ports correctly to the device to which the port is connected.

port if you define the spanning-tree port type network default command in global configuration mode.
If you enable Bridge Assurance globally, it automatically runs on this port.
Configuring STP Extensions Using Cisco NX-OS
Purpose
Enters global configuration mode.
Specifies the interface to configure and enters interface
configuration mode.
Configures the specified interfaces to be spanning network ports.
If you enable Bridge Assurance, it automatically runs on network
ports. By default, spanning tree ports are normal port types.
Exits interface configuration mode.
(Optional)
Displays the STP configuration including the STP port type if
configured.
