Configuring DHCP Lease Query in Subscriber Management
Overview: Configuring DHCP lease query
The F5® Policy Enforcement Manager™ (PEM) obtains DHCP lease information from the DHCP servers, to create new PEM™ sessions. There is support for both IPv4 and IPv6. When data packets arrive at BIG-IP® system, PEM also uses DHCP lease query to obtain IP lease information and re-create the PEM sessions.

Configure the source and destination setting, during forwarding mode only. In the relay mode, the client does not have an IP address and the DHCP provides the client with an IP address.The system will create a virtual server using the address or network you specify.
