Command introduced in Release 8.5 of JUNOS software.
Release or renew the acquired IP address for a specific interface.
To view the status of the Dynamic Host Configuration Protocol (DHCP) clients on the specified interfaces, enter the show system services dhcp client interface-name command.
This command is supported on J-series and SRX-series devices.
release interface-name —Clears other resources received earlier from the server, and reinitializes the client state to INIT for the particular interface.
renew interface-name —Reacquires an IP address from the server for the interface. When you use this option, the command sends a discover message if the client state is INIT and a renew request message if the client state is BOUND. For all other states it performs no action.
