Ramon,
you must not use EAPS and STP at the same port. This are clashing
protocols. There is no priority what should happen if EAPS i.e. decides
to open the VLAN and STP says no. Please use on yur ring ports only EAPS
and you should see the behavior you expect. STP you can use at your
access links.
reg, Hanno
