Nortel (untested)
Are Notel still in buisiness ? I heard they invested heavily in mobile interweb and went bust.
No, they're still in business. The products we looked at recently are fairly new.
You really want to be looking for a few key differentiators such as:
* can the device support 802.1x & mac-based fallback at the same time?
Yes !!! The issue that I have with most of the current switches, is that they can't fallback to mac based auth...
Really? I didn't do the testing personally, but I'm fairly sure most of the ones we tested did support it. Certainly 3Com, Cisco and Extreme do.
* can the device authenticate >1 client on a port? * if so, can it support 802.1x for one and mac-based for another (think IP phones)
This would come under fallback.
Not necessarily - some devices can fallback, but only in a mode with permits 1 mac per port.
* if so, can it assign separate untagged vlans to each client? * can the device assign IP ACLs from Radius replies? * can the device assign 1 untagged and >1 tagged vlans (think wlan aps)
I don't think many will allow you to assign multiple tagged VLANS, most centre around assigning one untagged VLAN... though that would be a very neat feature.
Extreme can.
