Cisco Switch: "AAA: Warning authentication list "default" is not defined for LOGIN"

Have you ever seen this message before when trying to deal with logins for a switch?  I have.  You have to go define what "default" is in the system.  Here is what you do to fix this on the Cisco 3750X:

Switch(config-line)#line con 0
Switch(config-line)#login authen default
AAA: Warning authentication list "default" is not defined for LOGIN.

Switch(config-line)#exit
Switch(config)#aaa new-model
Switch(config)#aaa authentication login default local
Switch(config-line)#line con 0
Switch(config-line)#login authen default
Switch(config-line)#exit
