8. Reload the new switch image.
Switch1# reload
System will be rebooted from primary image. Do you want
to continue [y/n]? y
At the prompt, enter ‘y’, for yes, and the switch will boot with the new image.
NOTE: As an additional step, we recommend saving the startup-config to a tftp server using
the copy tftp command. For example:
Switch1# copy startup-config tftp 10.1.1.60
Switch1_config_K_15_10_0001.cfg
Rolling back switch software
If you have followed the update procedures documented in the previous section, you should be
able to revert to your previous configuration and software version using the steps below.
CAUTION: Long usernames and passwords. Software versions K.15.01.0032 and later support
the longer usernames and passwords introduced in K.14.59.
Before downgrading to a software version that does not support long user-names and passwords,
use one of the following procedures:
• Using the password CLI command or the Web browser interface, change usernames or
passwords to be no more than 16 characters in length, and without any special characters.
Then execute a CLI write memory command (required if the include-credentials feature has
ever been enabled).
• Clear the values using the no password all CLI command. Then execute a CLI write memory
command (required if the include-credentials feature has ever been enabled).
• Clear password values by using the "Clear" button on the switch. Then execute a CLI write
memory command (required if the include-credentials feature has ever been enabled).
Note: The procedures above should be used only when downgrading from a software version that
supports long usernames and passwords to a version that does not.
To roll back your switch from K.15.01.0031 to K.14.47, for example, follow the steps below:
1. Verify that your images and configuration are set correctly using the show version, show flash
and show config files commands.
