Is Summit and/or BlackDiamond support multi devices authentication on single port? I mean that authentication status and policy will be applied exclusively per device, so a device may be authenticated whether the others may be not even they are connected to the same port. I find that way on Brocade (Foundry) device which is MAC address based authentication but I'm no sure Extreme net login has same behavior.
Is there a documentation / slide deck, which describes the differences between Enterasys and Extreme Switches? In sort of capabilities, handling of RADIUS Server down events, ...
The figure you mention is the number of MAC addresses supported by the FDB. The number I mentioned is specific to MAC addresses in Network login with the MAC-based vlans feature.
