Upgrading Operating Software | Switch Administration |
The switch stores the IP address of the TFTP server, the path, and the backup file name. The next time you enter the backup or restore commands, these values are presented as the default IP address and path. For example, when you enter the restore command, the following display appears:
SmartCell ZX# restore switch
ServerIP(90.1.1.100) :
SmartCell ZX #
Backup file is valid.
Restoring a backup file will completely replace any data stored in the flash. Are you sure this is what you want to do?
Confirm(y/n)?: y
SmartCell ZX #
Note You must reboot the switch for the restore to take effect.
4.2UPGRADING OPERATING SOFTWARE
You can upgrade the operating software of the SmartCell 6A000 while the switch is running its current software. This procedure is known as a hot upgrade and is accomplished by the update firmware command.
When the switch is started (or rebooted), it copies its operating software from flash RAM to the CPU program memory. When you perform a hot upgrade, the image in flash RAM is erased and replaced with the new software image. While the upgrade is occurring, the switch continues to run the copy in program memory. When the switch is rebooted, the new software image residing in flash RAM is copied into system memory and then run.
To use the hot upgrade feature, the switch must have network access to an end station running TFTP server software. The SmartCell 6A000 operating software file must reside within the directory specified by the TFTP server software. Often, this directory is /tftpboot. However, it may be different with your TFTP server software.
The following is an example of a hot upgrade:
SmartCell ZX # update firmware
ServerIP() : 128.95.77.210
Path() : server.ima
You are updating the code image in the flash.
Are you sure this is what you want to do?
Confirm(y/n)?:y
Erasing Flash.
Using TFTP to get and program bootfile server.ima from 128.95.77.210. 2672K
2737100 bytes received. Image Updated.
You will have to reboot for the new image to take effect.
SmartCell ZX #
Notice that the update firmware command does not use bootp to find the TFTP server. Instead, the update firmware command requires that you specify the IP address of the TFTP server, the path to the image file, and the file name.
