For J-EX Series switches . Configure a server identifier. The identifier can be used to identify

a DHCP server in a DHCP message. It can also be used as a destination address from

clients to servers (for example, when the boot file is set, but not the boot server).

between multiple lease offers. Clients include the server identifier in

messages to select a lease and indicate which offer is accepted from multiple lease

offers. Also, clients can use the server identifier to send unicast request messages to

specific DHCP servers to renew a current lease.

request and receive an IP address from itself or another DHCP server.

interface address used by the server to receive a client request. For example, if the client

sends a DHCP request and the server receives it on

—IPv4 address of the server. This address must be accessible by all clients served

within a specified range of addresses (based on an address pool or static binding).
