Enabling Bpdu Guard Globally - Cisco Nexus 9000 Series Configuration Manual

Configuring STP Extensions Using Cisco NX-OS
Step 6
This example shows how to configure the Ethernet interface 1/4 to be a spanning tree network port:
switch# config t
switch(config)# interface ethernet 1/4
switch(config-if)# spanning-tree port type network
switch(config-if)# exit
switch(config)#

Enabling BPDU Guard Globally

You can enable BPDU Guard globally by default. In this condition, the system shuts down an edge port that
receives a BPDU.
Note We recommend that you enable BPDU Guard on all edge ports.
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.
