Replacing or clearing the public-key file
The client public-key file remains in the switch flash memory even if you erase the startup-config file, reset the switch, or reboot the switch.
Remove the existing client public-key file or
specific keys by executing the clear crypto public-key
command.
This clears the public keys from both management modules. The module
that is not active must be in standby mode.
Syntax:
clear crypto public-key
Deletes the client public-key file from the switch.
Syntax:
clear crypto public-key 3
Deletes the entry with an index of 3 from the client public-key file on the switch.
