To configure foreign agent functionality, use the following command:
ip mobile foreign-agent {lifetime <seconds> | max-visitors <number> |
registrations {interval <msecs> | retransmits <number>}}
To configure home agent functionality, use the following command:
ip mobile home-agent {max-bindings <number>|replay <seconds>}
To configure proxy mobile IP and DHCP functionality, use the following command:
ip mobile proxy
auth-sta-roam-only | event-threshold <number> | log-trail | no-service-timeout <seconds> |
on-association | stale-timeout <seconds> | trail-length <number> |trail-timeout <seconds>
To configure revocation functionality, use the following command:
ip mobile revocation {interval <msec>|retransmits <number>
To enable packet trace for a given MAC address, use the following command:
ip mobile packet-trace <host MAC address>
Proxy Mobile IP
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:
l Derives the address of the home agent for a mobile client from the HAT using the mobile client’s IP address.
If there is more than one possible home agent for a mobile client in the HAT, the proxy mobile IP module
uses a discovery mechanism to find the current home agent for the client.
l Detects when a mobile client has moved. Client moves are detected based on ingress port and VLAN
changes, and mobility is triggered accordingly. For faster roaming convergence between AP(s) on the same
controller, it is recommended that you keep the on-association option enabled. This helps trigger mobility
as soon as 802.11 association packets are received from the mobile client.
