BOOTP Client Configuration 93
BOOTP Client
Configuration
Overview of BOOTP
Client
A BOOTP client can request the server to allocate an IP address to it using BOOTP
(bootstrap protocol). These two major processes are included on the BOOTP client:
■ Sending BOOTP Request message to the server
■ Processing BOOTP Response message returned from the server
In obtaining an IP address using BOOTP, the BOOTP client sends the server the
BOOTP Request message. Upon receiving the request message, the server returns
the BOOTP Response message. The BOOTP client can then obtain the allocated IP
address from the received response message.
The BOOTP message is based on UDP, so a retransmission mechanism in the event
of timeout is used to guarantee its reliable transmission. The BOOTP client also
starts a retransmission timer when it sends the request message to the server. If
the timer expires before the return of the response message from the server, the
request message will be retransmitted. The retransmission occurs every five
seconds and the maximum number of retransmissions is three, that is, the
message shall not be retransmitted after the third time.

Configuration
BOOTP client is described in the following section.
Configuring a VLAN Interface to Obtain the IP Address Using BOOTP

By default, the VLAN interface cannot use BOOTP to get an IP address.
For further information on IP Address configuration, please refer to the Getting
Started Guide that accompanies your Switch.
