FTOS Configuration Guide for the C-Series - Force10 Networks

To use local authentication for enable secret on console, while using remote authentication on VTY lines,
perform the following steps:
Force10(config)# aaa authentication enable mymethodlist radius tacacs
Force10(config)# line vty 0 9
Force10(config-line-vty)# enable authentication mymethodlist
Server-side configuration
TACACS+: When using TACACS+, Force10 sends an initial-packet with service type SVC_ENABLE,
and then, a second packet with just the password. The tacacs-server must have an entry for username
$enable$.
RADIUS: When using RADIUS authentication, FTOS sends an authentication packet with the following:
Username: $enab15$
Password:
Therefore, the RADIUS server must have an entry for this user name.
AAA Authorization
FTOS enables AAA new-model by default.You can set authorization to be either local or remote. Different
combinations of authentication and authorization yield different results. By default, FTOS sets both to
local.
Privilege Levels Overview
Limiting access to the system is one method of protecting the system and your network. However, at times,
you might need to allow others access to the router and you can limit that access to a subset of commands.
In FTOS, you can configure a privilege level for users who need limited access to the system.
Every command in FTOS is assigned a privilege level of 0, 1 or 15. You can configure up to 16 privilege
levels in FTOS. FTOS is pre-configured with 3 privilege levels and you can configure 13 more. The three
pre-configured levels are:
• Privilege level 1—is the default level for the EXEC mode. At this level, you can interact with the
router, for example, view some show commands and Telnet and ping to test connectivity, but you
cannot configure the router. This level is often called the “user” level. One of the commands available
in Privilege level 1 is the enable command, which you can use to enter a specific privilege level.
• Privilege level 0—contains only the end, enable and disable commands.
