90 CHAPTER 3: GETTING STARTED
Roaming creates the following effects:
■ Remote Authentication Dial-In User Service (RADIUS) accounting is
treated as a continuation of an existing session, rather than a new
one.
■ For tracked users, you can view roaming history in the Monitor tab.
See “Using the Client Monitor Window” on page 420.
■ The old session is cleared from the WX, even if the client did not
explicitly disassociate from the MAP and the 802.1X reauthentication
interval has not lapsed.
Traffic Ports Used by
a Mobility Domain
When deploying a Mobility Domain, you might attach the WX switches to
subnets that have firewalls or access controls between them. Within a
Mobility Domain, the WX switches exchange information and other types
of traffic, depending on your configuration of AAA and various
management services.
Table 12 provides a summary of the traffic ports typically used by a
Mobility Domain and its associated AAA and management functions.
