[A] :
The console server should begin to boot off the network and the new image is downloaded. At this
point, follow the upgrade process to save the new zImage file into Flash again.
NOTE: Possible causes for the loss of Flash memory may include downloaded wrong zImage file, downloaded
as ASCII instead of binary or problems with Flash memory.
If the console server booted properly, the interfaces may be verified using ifconfig and ping. If ping
does not work, check the routing table using the command route.
The file /etc/config_files contains a list of files that are affected by saveconf and restoreconf
commands. At the command prompt issue the command cat /etc/config_files to see the list of files
that are available in the Flash and are loaded into the Ramdisk at the boot time.
NOTE: If any of the files listed in /etc/config_files are modified, the console server administrator must execute the
command saveconf before rebooting the console server or the changes are lost. If a file is created (or a filename
altered), its name must be added to this file before executing saveconf and rebooting. This speeds up the
resolution of most problems.
Setting the maximum number of bytes received by the interface
You can avoid CPU overload by setting a limit to the rate of bytes received. The bootconf utility
offers a way of setting this limit. The default is set to 0, which disables the function. For optimum
performance set the value to 50000.
