TCP/IP Network Characteristics
Learning IP Information From a BOOTP Server
Introduction
Instead of manually configuring IP information, you can have the access server
learn its IP address and other IP configuration information from a BOOTP server
on the network. If you use the BOOTP server to load the CNAS software on the
access server, it can also learn its IP configuration from the BOOTP server during
the load operation.
BOOTP Server Configuration
Refer to the CNAS installation instructions for information about configuring a
BOOTP server.
Learning Operation
The following occurs when the access server learns IP configuration information
from a BOOTP server:
• If you use a BOOTP server to load the software image on your access server,
the access server learns the IP configuration information during the boot
operation.
• If you use MOP to load the software image on your access server, the access
server learns the IP configuration information after initialization.
• If you disable INTERNET, the access server does not learn its IP address and
no IP functions work. You can enable INTERNET at any time to start the
address learning process.
• If you enable INTERNET, you cannot disable it operationally (that is, using a
SET command) because the access server cannot easily ensure that an Internet
function is not pending or occurring. You must use the DEFINE INTERNET
DISABLE command and reboot the access server.
• When the access server is learning an IP address, you can use the
SHOW/MONITOR INTERNET command to display the status of the learning
operation. If learning is occurring, the IP address displays as “(Learning)”.
