Extreme Summit48si. > The switches should have 12 - 24 Fast Ethernet ports. Some form of "Q > in Q" or stackable VLANs, ie. the ability to handle more than one VLAN > tag, is vital. You can do this by changing the ethertype of VLANs, Extreme calls this VMAN (9100 for vlans intead of 8100). This requires a network design to match. The switch has 48 ports and two SFP gig ports. > Spanning tree is needed, but can be one common spanning tree for all > VLANs (per-VLAN spanning tree is not needed).

I dont know about RSTP and MST, but it does the rest. It also has EAPS for subsecond L2 failover. -- Mikael Abrahamsson email: [EMAIL PROTECTED]
