Parameter Description
EncapsulationS upported Thisparam etershows the type of encapsulation currently supported on thecontroll er.
Clear Trail Entries Clear thestation location trail table. You can view entries in this table using theshow ip
mobile trail command.
Clear Mobility Counters Clear counters forIP mobility statistics.
ForeignAgent
lifetime Requestedli fetime, in seconds, as per RFC 3344,“IP Mobili tySupport for IPv4”. The range of
allowed values is 10-65534seconds. The default setting is 180 seconds.
Max.V isitorsAll owed Seta maxi mum allowed number of active visitors. The range of allowed values for this option
is0-5000 visitors. The default setting is 5000 visitors.
RegistrationRequests
Retransmits
Maximum number of times the foreign agentattempts mobile IP regi strationmessage
exchangesbefore giving up. The range of allow ed valuesfor this option is 0-5 attempts. The
defaultsetting is 3 attempts.
RegistrationRequests
Interval
Retransmissioni nterval, in milliseconds. The range of allowed values for this option is 100-
10000milliseconds, inclusive. The default setting is 1000mill iseconds.
HomeAgent
Replay Tim e difference, in seconds, for timestamp-based replay protection, as described by R FC 3344,
“IPMob ility Support for IPv4”. 0disables replay. The range of all owed values is 0-5000
seconds.The default setting is 5000 seconds.
Max.Bindi ng Allowed Maximumnum ber ofm obile IP bindings. Note that there is a license-based limit on the
number ofusers and a one user per binding li mit in addition to unrelated users. This option is
anaddi tional limitation to control the maximum number of roaming users. When the lim it is
reached, registrationrequests from the foreign agent fail which causes a mobile cli entto set
anew sessionon the visited controller, which w ill become its home controller.
Therange of all owed values is 0-300seconds. The default setting is 7 seconds.
ProxyMobil e IP
Trigger Mobility on Station
Association
Ifenabled, m obility move detection is performed when the client associateswi ththe
controller instead of when the client sends packets.
Thisoption i senabl ed bydefault. Mobi lity on associationcan speed up roami ng and improve
connectivityfor devices that do not send many upli nk packetsout that can trigger m obility. The
downside tothis option is low ered security;an association is all ittakes to trigger mobility,
however, this is irrelevant unless layer-2 security is enforced.
StandAlone AP Support Enablessupport for third party or standalone APs. Whenthis is enabl ed, broadcast packets
arenot used to trigger mobili tyand packets from untrusted interfacesare accepted.
Ifmobil ityi senabl ed, you mustal soenabl e standaloneAP for the client to connect to the
controller’s untrustedport. If the controller learns wired users via the following methods,
enable standaloneAP:
lThird partyAP connected to the controller through the untrusted port.
lClients connectedto ENET1 on the W-AP70.
lWired user connecteddi rectlyto the controller’s untrusted port.
WhenIP m obility is enabled, you must also enable the Stand Alone AP Support option so that
atunneled node server can perform properly and display all w ired usersw ho are connected
toa tunneled node port.
