Parameter Description
Range: 0-300 seconds
Default: 7 seconds
Proxy Mobile IP
Trigger Mobility on
Station Association
If enabled, mobility move detection is performed when the client associates with
the controller instead of when the client sends packets.
This option is enabled by default. Mobility on association can speed up roaming
and improve connectivity for devices that do not send many uplink packets out to
trigger mobility. The downside to this option is lowered security. An association
alone triggers mobility; however, this is irrelevant unless layer-2 security is
enforced.
Mobility Trail Logging Enables logging at the notification level for mobile client moves.
Roaming for
Authenticated Stations
Only
Allows a client to roam only if has been authenticated. If a client has not been
authenticated, no mobility service is offered if it roams to a different VLAN or
controller.
Max. Station Mobility
Events per Second
Maximum number of mobility events (events that can trigger mobility) handled
per second. Mobility events above this threshold are ignored. This helps to
control frequent mobility state changes when the client bounces back and forth
on APs before settling down.
Range: 1-65535 events
Default: 25 events
Station Trail Timeout Specifies the maximum interval, in seconds, an inactive mobility trail is held.
Range: 120-86400 seconds
Default: 3600 seconds
Station Trail Max.
Entries
Specifies the maximum number of entries (client moves) stored in the user
mobility trail.
Range: 1-100 entries
Default: 30 entries.
Mobility Host Entry
Hold Time
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. In
many case a station state is deleted without waiting for the stale timeout; user
delete from management, foreign agent to foreign agent handoff, and so on.
(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.)
Mobility Host Entry
Lifetime
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.
