i have some ME-3600x. some of version 12.2 and one of version 15.5. te last one hast same config as all other. but if i check for rstp it sends
No spanning tree instance exists.
i know abount global config commands:
spanning-tree mode rapid-pvst
spanning-tree extend system-id
but there is no spanning-tree support. this causes many more problems. so it is important to solve spanning tee at first.
is it possible without downgrading this device?
thanks for help
