VTY Line Remote Authentication and Authorization

FTOS retrieves the access class from the VTY line.
The Dell Force10 OS takes the access class from the VTY line and applies it to ALL users. FTOS does not
need to know the identity of the incoming user and can immediately apply the access class. If the
authentication method is radius, TACACS+, or line, and you have configured an access class for the VTY
line, FTOS immediately applies it. If the access-class is

connections from subnet 10.0.0.0 without displaying a login prompt. The example uses TACACS+ as the
authentication mechanism.

(same applies for radius and line authentication)

VTY MAC-SA Filter Support

FTOS supports MAC access lists which permit or deny users based on their source MAC address. With
this approach, you can implement a security policy based on the source MAC address.
To apply a MAC ACL on a VTY line, use the same
