However it only has 2xGig ports so have to uplink to a separate switch in the core to keep everything at a gig. Before purchasing new kit we have a couple of Extreme X450e switches. Their qinq implementation VMAN is supposedly compatible, providing Ethertype is set correctly. However documentation is a little light on details regarding configuration so I am wondering if anyone here has any experience with it. Current Cisco config below - can it be duplicated using VMAN?
