Description
This command configures the proxy mobile IP module in a mobility-enabled controller.
Syntax
Parameter Description Range Default
auth-sta-roam-
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. — enabled
block-dhcp-re
lease Determines whether DHCP release packets generated from
the client should be dropped or forwarded to the DHCP
server. Blocking the packets prevents the DHCP server from
assigning the same IP address to another client until the
lease has expired. — disabled
dhcp
Configures proxy DHCP — —
aggressive-
transaction
Terminate proxy DHCP state machine on a transaction id
change. New bootp request will kick start a new DHCP state
machine.
NOTE: Best practices is to keep this parameter at the default
setting 0-65534 25
ignore-options
Enables support for devices that use DHCP with zero options
(For example, Symbol).
NOTE: Best practices is to keep this parameter at the default
setting — disabled
max-requests
Maximum number of BOOTP packets that are allowed to be
handled during one DHCP session. 0-65534 25
transaction-
hold Hold time, in seconds, on proxy DHCP state after completion
of DHCP transaction (DHCP ACK) was forwarded to the client.
This option ensures that late BOOTP replies reach the station
and that a retransmitted BOOTP request does not trigger a
new proxy DHCP session. 1-600 5 seconds
transaction-
timeout
Maximum time allowed for a proxy DHCP session to
complete. 10-600 60 seconds
event-threshold
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. 1-65535 25
log-trail Enables logging at the notification level for mobile client — enabled
