Release History Table DescriptionRelease
Starting in Junos OS Release 14.1, you can modify the behavior of the process
in which the DHCP local server initiates reconfiguration of its clients by including
the appropriate configuration statements.
14.1
Requesting DHCP Local Server to Initiate Reconfiguration of Client Bindings
You can request that the DHCP local server initiate reconfiguration of all of clients or only
specified clients.
To request reconfiguration of all clients:
•
Specify the all option.
For DHCPv4:
user@host> request dhcp server reconfigure all
