7. The system then informs you which software image (image1 or image2) is currently set to
be loaded at the next reset, and prompts you to enter a new choice:
Currently set to use switch software "image1" on next reset.
Specify new image to use on next reset ["image1"/"image2"]:
Specify the image that contains the newly loaded software.
8. Reboot the switch to run the new software by running reset:
Boot Options# reset
The system prompts you to confirm your request. Once confirmed, the switch reboots to
use the new software.
Loading the firmware with ISCLI
To load the firmware with ISCLI, complete the following steps:
1. To determine the software version currently used on the switch, run show boot:
RS8264# show boot
2. In Privileged EXEC mode, run copy:
Router# copy {tftp|ftp} {image1|image2|boot-image}
3. Enter the host name or IP address of the FTP or TFTP server:
Address or name of remote host: <name or IP address>
4. Enter the name of the new software file on the server:
Source file name: <filename>
The exact form of the name varies by server. However, the file location is normally relative
to the FTP or TFTP directory (for example, tftpboot).
5. If required by the FTP or TFTP server, enter the appropriate user name and password.
The switch prompts you to confirm your request. Once confirmed, the software begins
loading into the switch.
6. When loading is complete, run the following commands to enter Global Configuration
mode to select which software image (image1 or image2) you want to run in switch
memory for the next reboot:
Router# configure terminal
Router(config)# boot image {image1|image2}
7. The system then verifies which image is set to be loaded at the next reset:
Next boot will use switch software image1 instead of image2.
8. Reboot the switch to run the new software by running reload:
Router(config)# reload
The system prompts you to confirm your request. Once confirmed, the switch reboots to use
the new software version installed.
7.2.4 Recovering from a failed firmware upgrade
Rarely, the firmware upgrade process fails. This situation is unlikely to happen, but if it
occurs, you can still recover from this situation. To recover your switch, connect a PC to the
serial port of your switch while the switch is off, and access the switch as described in the
appropriate User Guide (see “Related publications” on page 333).
