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 on aggressive Transaction ID change.
NOTE: Dell recommends keeping this parameter at the default setting:
0-65534 25
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 moves. — enabled
no-service-time
out
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.
30-60000 180 seconds
on-association 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.
— enabled
re-home Allows on-hook phones to be assigned a new home agent. This is to
load balance voice client home agents across controllers in a mobility
domain.
This parameter requires that you install the PEFNG license in the
controller.
— disabled
stale-timeout 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.)
30-3600 60 seconds
