Usage Guidelines
The proxy mobile IP module in a mobility-enabled controller detects when a mobile client has moved to a foreign
network and determines the home agent for a roaming client. The proxy mobile IP module performs the following
functions:

Description
moves.
Time, in seconds, after which mobility service expires. If
nothing has changed from the previous state, the client is
given another bridge entry but it will have limited
connectivity.
Mobility move detection is performed when the client
associates with the controller instead of when the client
sends packets. Enabled by default. Mobility on association
can speed up roaming and improve connectivity for devices
that do not send many uplink packets out that can trigger
mobility. Downside is security; an association is all it takes to
trigger mobility. This is irrelevant unless layer-2 security is
enforced.
Mobility forces station to renew its stale IP (assuming its
DHCP) by deauthorizing the station.
Number of seconds the mobility state is retained after the loss
of connectivity. This allows authentication state and mobility
information to be preserved on the home agent controller.
The default is 60 seconds but can be safely increased. Note
that in many case a station state is deleted without waiting
for the stale timeout; user delete from management, foreign
agent to foreign agent handoff, etc. (This is different from the
no-service-timeout; no-service-timeout occurs up front while
the stale-timeout begins when mobility service is provided
but the connection is disrupted for some reason.)
Enables support for third party or standalone APs. When this
is enabled, broadcast packets are not used to trigger mobility
and packets from untrusted interfaces are accepted.
If mobility is enabled, you must also enable standalone AP for
the client to connect to the controller's untrusted port. If the
controller learns wired users via the following methods,
enable standalone AP:
Third party AP connected to the controller through the
l
untrusted port.
Clients connected to ENET1 on APs with two ethernet
l
ports.
Wired user connected directly to the controller's
l
untrusted port.
Specifies the maximum number of entries (client moves)
stored in the user mobility trail.
Specifies the maximum interval, in seconds, an inactive
mobility trail is held.
