Configuring Terminal Start-Up Resources

In a local-boot environment, DHCP can provide a set of configuration parameters,
which reduces the need to configure the terminal’s Select | System | Setup |
Select | System | Setup | Select | System | Setup | Select | System | Setup |
Connectivity | Internet | DHCP Connectivity | Internet | DHCP Connectivity | Internet | DHCP Connectivity | Internet | DHCP dialog box. The default (out of the box)
configuration assumes DHCP provides all network configuration information. As
such, the fields mentioned above for BOOTP all apply, except that the TFTP server
(
sa
), TFTP boot file (
bf
), and Root directory (
T17
) are not used. Providing them in
a mixed (local- and network-boot) environment is acceptable, since they are
ignored completely in a locally booted terminal.
Boot Server (see on-line help), otherwise known as “Buddy Boot,” uses these
options to give preference to a server that provides these options, servers for use
with local boot should use these options with extreme caution, since it may prevent
Boot Server from working.
The terminal renegotiates address information based upon the server’s configured
value for the lease time. If lease time is set for an infinite lease, the terminal will not
renegotiate for a lease extension or a new IP address until the terminal is rebooted.
At reboot, the terminal will once again ask for an IP address and other configuration
information.
The terminal uses the DHCP options listed in Table 2-1. Future releases may
increase the size of the list. Some of the listed options are sent by the server and
others are sent by the client. Refer to the RFCs (listed in “
References” in the
“
Overview” chapter of this document) for usage.
