Router Start-up
At start-up, the manager can choose to run either the software release stored in
EPROM or flash (depending on the model of router), or the software release
specified by the INSTALL parameters previously set using the SET INSTALL
command. (AR300 Series routers, AR720, and AR740 routers boot from
EPROM, while AR400 Series routers, AR725 and AR745 routers boot from
flash.)
All code is executed out of system DRAM. At power-up the boot code is loaded
from EPROM (or flash for AR400s, the AR725 and AR745) to DRAM. The boot
code checks the INSTALL information then reloads DRAM with the selected
temporary , preferred, or default install release (which is stored in flash) and runs
this code.
If the install release is a compressed release, the release is uncompressed as it
loads to DRAM. This may take 20–30 seconds. At this point, any required
patches are loaded from flash. If a patch is compressed, it is uncompressed as it
loads to DRAM. This procedure ensures that the code runs at maximum speed
(DRAM is faster than EPROM), and allows updates to be made to the code.
Updates can be downloaded over the network from a TFTP server and stored
in flash until required at power-up.
See the Software Reference (Chapter 1, Operation), for a description of the downline
loading method. The code can also be loaded from the flash memory, under user control.
The Operation chapter also has a detailed description of flash memory.
All router software, patches, and configuration settings are stored as files in
flash memory. Typically, the following files will be present in flash:
■ The current installed software release. Additional software releases may
also be present.
■ The current installed patch, if any. Additional patches may also be present.
■ The online help file. All online help is stored in a language independent
text file. Users can create and install their own online help file, to support
different languages or to provide site-specific information.
■ The boot script
boot.cfg
. The boot script contains standard router
commands (executed on start-up to configure the router).
■ Additional user-defined configuration scripts containing commands to
configure the router for different functions. These scripts are created using
the built-in editor, the ADD SCRIPT command
, Scripting , or the CREATE
CONFIG command.
