I can login to my ICX6540 switch with my user account but always it asks for enable password . I need to disable the enable password so I can access to privilege mode directly
Yes sure. Add this command "aaa authentication login privilege-mode". In this way the device enters the Privileged EXEC mode after a successful login through Telnet or SSH.
If you want to have a 1st login/password to access the switch, you can use "aaa authentication login default local". This line refers to an authentication based on local created user. So this needs a config line with something like "username YOUR-NAME password ...".
I have local admin account and also command "aaa authentication login default local" I can access with my local account but I have to enter the enable password my request is to use my local admin account only without the need to enter enable password as well
