Thanks you, it is working now as we expected.  Now I have a question, how
many virtual IP interfaces  support the summit 48si and 300-48.

Thanks.

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
