Usage Information
You can use this command to associate a group of TACACS servers with a VRF and
source interface. You can configure the source interface only with the VRF
attribute and source interface is optional with the VRF attributes.
If VRF is not configured on the TACACS group, then the group is considered to be
on the default VRF.
RADIUS groups and VRFs have one-to-one mapping. If a VRF is configured with
one RADIUS group, then you cannot use the same VRF with another RADIUS
group. When the VRF is removed, then the corresponding RADIUS group is also
removed automatically.
Example
Dell(conf)# tacacs-server group group1
Dell(conf-tacacs-group)# tacacs-server vrf vrf1 source-
interface gigabitethernet 1/36
Dell(conf)# tacacs-server group group2
Dell(conf-tacacs-group)# tacacs-server vrf default
Port Authentication (802.1X) Commands
An authentication server must authenticate a client connected to an 802.1X switch port. Until the
authentication, only Extensible Authentication Protocol over LAN (EAPOL) traffic is allowed through the
port to which a client is connected. After authentication is successful, normal traffic passes through the
port.
Dell Networking OS supports RADIUS and Active Directory environments using 802.1X Port
Authentication.
