authentication login

This command defines the login authentication method and precedence. Use the no form to restore the default.

Syntax

authentication login {[local] [radius] [tacacs]} no authentication login

local - Use local password.

radius - Use RADIUS server password.

tacacs - Use TACACS server password.

Default Setting

Local

Command Mode

Global Configuration

Command Usage

RADIUS uses UDP while TACACS+ uses TCP. UDP only offers best effort delivery, while TCP offers a connection-oriented transport. Also, note that RADIUS encrypts only the password in the access-request packet from the client to the server, while TACACS+ encrypts the entire body of the packet.
