Configuring The Dhcp Client - Intermec 6400 User Manual

6400 TCP/IP Client
" NOTE:
2-52 6400 Computer TCP/IP Client User's Guide
When a lease expires, network connections are lost. However, the
DHCP client continues to broadcast over the network to discover
another DHCP server that will grant it a lease.

Configuring the DHCP Client

You can obtain network configuration information in DOS
with the dhcp command by doing one of the following:
Enabling the DHCP client through the 6400 TCP/IP
"
client DOS configuration menus
Typing the dhcp command at the DOS prompt
"
Entering the dhcp command in AUTOEXEC.BAT
"
(after the ETHDRV.EXE command) so the command
runs when you start your 6400 computer
The command line interface for dhcp is similar to that of
the bootp command (discussed on page 2 54, Configuring
the Bootp Client"). The primary difference is that, with
DHCP, addresses are leased
assignment is considered permanent. Because of this
difference, the DOS dhcp command installs a TSR module
so that the lease can be renewed automatically.
The dhcp command can handle replies from either DHCP
or Bootp servers. If a Bootp server reply is received, or if
the DHCP server reply indicates an infinite lease, no TSR
module is loaded since there is no lease to maintain.
While dhcp properly handles Bootp replies, you should use
bootp when you will be receiving replies from Bootp
servers and not from DHCP servers. Bootp provides some
Bootp specific options that are not available with dhcp.
Configuration parameters for dhcp are located in the
[pctcp bootp] section of PCTCP.INI. The Configuration
Parameter Reference on the FTP Software, Inc. Web site
lists dhcp configuration parameters. The URL for FTP
Software is http://www.ftp.com.
