Resetting a Switch to Factory Default Settings
Resetting a Switch to Factory Default Settings
Manufacturing and repair centers can use the erase /all non-default command to do the following:
• Clear the non-volatile configurations and states of the local supervisor engine (NVRAM and
flashes).
• Set the factory default parameters on the Catalyst 4500 series switch before it is ready to ship to a
customer.
For example, entering this command can generate the following output:
Switch# erase /all non-default
Erase and format operation will destroy all data in non-volatile storage. Continue?

If the Catalyst 4500 series switch is accessible to an tftp server, you can copy an image to the bootflash
memory with the tftp command:
Switch# copy tftp://192.20.3.123/tftpboot/abc/cat4500-entservices-mz.bin bootflash:
When the copying completes, you can reboot the just-copied Catalyst 4500 series switch image to the
image stored in the bootflash memory with the reload command:
Switch# reload
