Ok, obviously I need to explain this to you.
the 4500, UNLIKE THE 655, does not have 24 pre-defined windows for MAC addresses. What I said was if you need more then 24, then the 4500 does not have this 24 entry limitation.
However the 4500 will be limited by the number of other user defined entries made.
In other words every DHCP reservation, MAC entry, schedule, port forward rule, QoS rule, all take away from the same memory pool.
Now that you understand I'm going to lock this thread.
