Command History
This guide is platform-specic. For command information about other platforms, see the relevant Dell Networking
OS Command Line Reference Guide.
Version Description

Usage Information
You can use this command to associate a group of TACACS servers with a VRF and source interface. You can
congure the source interface only with the VRF attribute and source interface is optional with the VRF attributes.
If VRF is not congured 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 congured 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) trac is allowed through the port to which a client is connected. After authentication is
successful, normal trac passes through the port.
Dell Networking OS supports RADIUS and Active Directory environments using 802.1X Port Authentication.
