System-wide commands
This section describes system commands that are available in the BOOT Loader.
Viewing the invariant information in BOOT Loader
Invariant information is shared between the BOOT PROM image, the BOOT Loader
image and the main image. This is common information in all the image files.
To view invariant information, use the
system invariant
command.
Viewing a list of fatal system exceptions
A fatal system exception occurs when the Central Processing Unit (CPU) detects an
error such as a division by zero, or accesses to non-existent memory. A fatal
exception causes the M770 ATM Switch to reboot. A breakpoint is a special type of
exception which is invoked by the M770 ATM Switch software when it detects an
internal inconsistency.
