Configuring Spanning Tree Network Ports on Specified Interfaces
• no spanning-tree port type—This command implicitly enables the port as a spanning tree network
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.
A port connected to Layer 2 hosts that is configured as a network ports automatically moves into the
Note
blocking state.
Before You Begin
Before you configure the spanning port type, you should do the following:
• Ensure that STP is configured.
• Ensure that you are configuring the ports correctly as to the device to which the port is connected.

Configuring STP Extensions Using Cisco NX-OS
Purpose
Enters configuration mode.
Specifies the interface to configure, and enters
the interface configuration mode.
Configures the specified interfaces to be
spanning network ports. If you enable Bridge
Assurance, it automatically runs on network
