I've raised a case with our Support partner and am still getting no comfortable feeling from them as to why RSTP is still blocking my interfaces.
All links between switches have now been configured as 'access'.
Each link is a 'l3-interface' with a unique subnet and VLAN.
I've completely removed all unused interfaces from 'default' VLAN.
So why on earth is RSTP still blocking interfaces!? This is driving me nuts.
My heart says disable RSTP globally, but my head says I should keep it enabled and figure this out.
