288 Configuring the Wireless Array
Arrays have a fast roaming feature, allowing them to maintain sessions for
applications such as voice, even while users cross boundaries between Arrays.
Fast roaming is set up in the Global Settings (IAP) window and is discussed in:
 “Understanding Fast Roaming” on page 288
IAPs are configured using the following windows:
 “IAP Settings” on page 290

IAP Statistics Summary
Understanding Fast Roaming
To maintain sessions for real-time data traffic, such as voice and video, users must
be able to maintain the same IP address through the entire session. With
traditional networks, if a user crosses VLAN or subnet boundaries (i.e., roaming
between domains), a new IP address must be obtained.
