running Sup V's that is as close to a 3750 running IOS version 12.2(37)SE. I used the 3750 to do some testing with 802.1X and want to get as close to that as possible with the 4507. The only version I can find is 12.2.37-SG (ED) and not sure if there's a better version out there.
3750 supports all these features in the current IOS. Even it supports both guest vlan and authentication failed vlan for the wired users. I think 12.2.37 code on both 4500 and 3750's have almost the same capabilties.
HTH,Please rate if it does.
