Hi,

If we are talking about RSTP (802.1w), I think you miss carrier VLAN ID. Carrier VLAN is the one that will carry STP BPDUs. See an example from EXOS User Guide in the image attached.


If it still won't be working, please attach here:
  • 'show stpd'
  • 'show stpd s0'
  • 'show stpd s0 ports detail'
It's more than enough, but we will be able to walk through the analysis of RSTP status in your network together.

Kind regards,
Tomasz
