Designing Access Controls
Choose RADIUS Servers
2.Are you concerned with minimizing traffic on WAN links? (And is this concern more important than simplifying management? See step 1.)
WAN links can be relatively slow and
•To eliminate all or most access control related traffic, choose multi- site autonomous or possibly (if you have selected the general option)
