how can i change the password and username for the following devices :
- WS-C3850-48F-S (CORE SWITCH)
- ASA5516-FTD-K9 (ASA FW)
- C1-AIR-CT3504-K9 (WLC)
yes i have access to all devices already and need to just change password with strong one thats why , so
shall i put 0 for the changing [password because im using the below :
username ciscoadmin privilege 15 secret 4 vwcGVdcUZcRMCyxaH2U9Y/PTujsnQWPSbt.LHJK8lhTw
so if i use 4 instead 0 is it okay ? while changing ?
also should i remove the old one ?
Unless you already have the encrypted value of your new strong password you should not include the 4 in your command. Assuming that you will be entering the new stronger password in clear text you should use 0 in the command
