Configuring SNMP, BootP, DHCP, and RARP Services

If the client does not receive an answer from the DHCP server (perhaps because

the server is down at the renewal time), it can attempt to reacquire configuration

parameters and an IP address from another server, or let the lease lapse, returning

the IP address to a client pool. The client pool is a group of one or more client IDs

or MAC addresses maintained by a DHCP server.

DHCP Components

The Bay Networks implementation of DHCP consists of the following

components:

• DHCP clients

• DHCP server

• NetID Server Manager

The sections that follow describe these components in detail.

DHCP Clients

A DHCP client is a host that uses DHCP to obtain configuration information, such

as an IP address, from a DHCP server.

DHCP Server

A DHCP server is a host that provides IP addresses and configuration parameters

to DHCP clients.

NetID Server Manager

The Server Manager operates as an interface between the DHCP server (see

Figure 2-6

). The NetID Server Manager manages and maintains IP addresses and

configuration information, and allocates IP addresses to the DHCP server. The

NetID Server Manager polls the database periodically and sends configuration

changes to the appropriate DHCP servers. The DHCP servers send updated

information to the NetID Server Manager, and the Server Manager puts this

information into the database.
