Hi everybody, I have a metro ethernet network at work that we have recently changed most of the switches with Extreme Networks (most exactly X670G2 and X460) and one of my clients is making us the question about support os L2 and L2CP protocols like TP, RSTP, MSTP, PVST, R-PVST,EAPS, pause, LACP/LAMP, GARP/MRP, Link OAM, Port Authentication, E-LMI, LLDP over our Network , and if it had exceptions like discarded/peer/tunnel. We are going to offer to him a Layer 2 service with Qinq maybe,I know that this question is not specific at all, but if you have some information about this that you can share with me, I will appreciate it. Thanks in advance.
