All configuration information is stored in FLASH memory as configuration scripts.
these scripts contain standard router commands. When a configuration command is
entered at the command prompt from a terminal, terminal emulation program, or Telnet
session, the command only alters the dynamic configuration. This is not saved over a
power cycle. To ensure that configuration changes resulting from such commands are
retained across a power cycle, the dynamic configuration must be saved as a
configuration script, using the CREATE CONFIG command.
When the router starts up following either a power cycle or an operator-
initiated reboot (using the RESTART command), the following sequence of
operations is performed:
1. Perform start-up self tests.
2. Load the EPROM release as the INSTALL boot into the router's RAM.
3. Prompt the manager for changes to the default start-up procedure:
Force EPROM download (Y)?
The manager may press one of the keys listed in Table 1 on page 12 to
override the default installation procedure.
4. Check the INSTALL information to determine which release to load and
run, according to the INSTALL parameters, and the manager's response to
the previous prompt. If none of the keys in Table 1 on page 12 are pressed,
the INSTALL parameters determine which release and patch are loaded and
run.
5. Load the required EPROM or FLASH release specified by the INSTALL
parameters as the main boot.
6. Start the router.
7. Execute the boot script (
A series of start-up messages is sent to Port 0 (The console or terminal port).
