Is there are way to disable spanning-tree globally on a cisco switch instead of per vlan? Can you provide the commmad? Why you ask..to bypass BPDUguard configured on another switch. Thanks in advance.
Solved! Go to Solution.

Hi,
As you already, it is not recommended to turn STP off.
There is no global command to disable spanning tree globally.
But, you can disable all configured vlan by "no spanning-tree vlan 1-max vlan no of your vlans"
SW1(config)#no spanning-tree vlan 1-1014
SW1#sh span
*Mar 1 22:18:00.536: %SYS-5-CONFIG_I: Configured from console by console
SW1#sh span
SW1#sh spanning-tree
No spanning tree instance exists.
Hope this helps.

Or apply BPDUfilter on all ports
Not recommending you do that, because that against the best practice; just want give you another option.

Hi,
wouldn't
spanning-tree bpdufilter enable
(see
for details)
be enough on the port connecting to the other switch?
