I have a stack of two SummitX690 with firmware 22.4.1.4 and i want to use spanning tree for LoopProtection.
To get new Vlans automatically add to stp "S0" i started the intended script "ezspantree.py" from Master. Unfortunately, this does not really work.
Show the CLI Output:


Slot-1 V9350013.1 # run script ezspantree.py start
Spanning Tree Easy Setup
- Configures spanning tree s0 mode to MSTP/CIST
- Scans all VLANs
   if a VLAN is not connected to spanning tree, it is added to s0
   if a VLAN is already connected to spanning tree s0, it is updated
   VLANs connected to spanning tree(s) other than s0 are not affected
- Starts a VLAN monitoring process for any new VLANS
   newly created VLANS are automatically added to spanning tree s0

Do you wish to proceed? [y/N] y
STP s0 is already configured for MSTP
Enabling STP s0
ezspantree started
Scanning all VLANs
        VLANs not connected to STP will be automatically added to s0

The same problem occurs in a mixed stack (X690/X870).
The script works well with same firmware if the switches are standalone.

Have anyone experiences regarding the script use in the stack?

Hi Andreas,

I have not tested with stack, however, I could see below conversation about same script.
