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
DellEMC(conf)# tacacs-server group group1
DellEMC(conf-tacacs-group)# tacacs-server vrf vrf1 source-interface
tengigabitethernet 1/36
DellEMC(conf)# tacacs-server group group2
DellEMC(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 EMC Networking OS supports RADIUS and Active Directory environments using 802.1X Port Authentication.
