Loading System Images and Configuration Files
To exit Configure mode and return to Enable mode, use one of the following commands:
Boot PROM Mode
If your GSR does not find a valid system image on the external PCMCIA flash, the system
might enter programmable read-only memory (PROM) mode. You should then reboot the
GSR at the boot PROM to restart the system. If the system fails to reboot successfully,
please call DIGITAL Equipment Corporation Technical Support to resolve the problem.
To reboot the GSR from the ROM monitor mode, enter the following command.
Disabling a Function or Feature
The CLI provides for an implicit negate. This allows for the “disabling” of a feature or
function which has been “enabled”. Use the
negate
command on a specific line of the
active configuration to “disable” a feature or function which has been enabled. For
example, Spanning Tree Protocol is disabled by default. If after enabling Spanning Tree
Protocol on the DIGITAL GIGAswitch/Router, you want to disable STP, you must specify
the
negate
command on the line of the active configuration containing the
stp
enable
command.
Loading System Images and Configuration Files
The GSR contains an internal flash on the Control Module and an external PC flash. The
internal flash contains the GSR boot image and user defined configuration files. An
external PC flash contains the system image executed by the Control Module. When a
GSR boots, the boot image is executed first, followed by the system image and finishing
with a configuration file.
Boot and System Image
Only one boot image exists on the internal flash of the GSR Control Module. Multiple
system images can be stored on the external PC flash.
Exit Configure mode.
