Command introduced in Junos OS Release 10.0.
Command introduced in Junos OS Release 12.3R2 for EX Series switches.
Initiate reconfiguration processing for the specified DHCP clients if they are in the bound
state. If the clients are in the reconfiguring state, this command has no effect. If the clients
are in any state other than bound or reconfiguring, this command has the same effect
as the clear dhcp server binding
When the local server state machine starts the reconfiguration process on a bound client,
the client transitions to the reconfiguring state and the local server sends a forcerenew
message to the client. Because the client was in the bound state before entering the
reconfiguring state, all subscriber (or DHCP client) services, such as forwarding and
statistics, continue to work. An exponential back-off timer determines the interval at
which the forcerenew message is sent. If the final attempt is unsuccessful, the client is
returned to its original state by default. You can optionally include the
statement to configure the client to be cleared when reconfiguration fails.
