Configuring SNMP, RMON, BOOTP, DHCP, and RARP Services
2-30 114070 Rev. B
Although BOOTP and DHCP use the same UDP port numbers (67 and 68), they
differ in the following ways:
DHCP defines a mechanism for clients to obtain their IP network address for a
fixed period of time (lease), allowing for reassignment of expired IP network
address to different clients.
DHCP provides a mechanism for clients to acquire all of the IP configuration
parameters needed to communicate on a network.
DHCP packet length is longer than for BOOTP.
The additional packet length allows a DHCP server to provide the client with
all the IP configuration parameters that it needs to operate.
DHCP is a more complicated protocol than BOOTP.
DHCP has seven message types; BOOTP uses only two.
Acquiring a New IP Address and New Configuration Parameters
DHCP acquires an IP address and other configuration parameters for clients. This
process involves the following stages:
Identifying DHCP servers
Requesting IP information
Receiving IP information
Accepting IP information
