To renew or terminate a DHCP lease on a subscriber host

Purpose

DHCP is used to assign IP addresses to hosts or workstations on the network. This function is usually performed by a DHCP server, which leases out addresses for specific times to the various hosts. If a host does not use a specific address for a set period of time, that IP address can be assigned to another machine by the DHCP server.

In order to allow the DHCP client to lease out an address for specific times, the NFM-P allows an operator to force the DHCP client to change its state by manually sending a Renew command. Upon receipt of the Renew command from the NFM-P, the DHCP client changes to the renewal state and negotiates with the DHCP server for lease times.

Conversely, an operator can also manually terminate (clear) a lease for a particular host from within the Residential Subscriber Host form of the NFM-P.

Note: The DHCP lease renewal and termination are supported only on dynamic hosts; not on static hosts or subscriber hosts.

Steps
 
1 

Choose Manage→Residential Subscribers from the NFM-P main menu. The Manage Residential Subscribers form opens.

Select Residential Subscriber Host (Residential Subscriber) and search for the SAP on which the subscriber hosts you want to manage are located.

  2. To terminate the lease, click Clear Lease State.

5 

Confirm the action.
