Important Points to Remember
Dell Networking OS limits network access for certain users by using VLAN assignments. 802.1X with VLAN assignment has these
characteristics when congured on the switch and the RADIUS server.
• 802.1X is supported on Dell Networking OS.
• 802.1X is not supported on the LAG or the channel members of a LAG.
• If no VLAN is supplied by the RADIUS server or if 802.1X authorization is disabled, the port is congured in its access VLAN after
successful authentication.
• If 802.1X authorization is enabled but the VLAN information from the RADIUS server is not valid, the port returns to the Unauthorized
state and remains in the congured access VLAN. This prevents ports from appearing unexpectedly in an inappropriate VLAN due to a
conguration error. Conguration errors create an entry in Syslog.
• If 802.1X authorization is enabled and all information from the RADIUS server is valid, the port is placed in the specied VLAN after
authentication.
• If port security is enabled on an 802.1X port with VLAN assignment, the port is placed in the RADIUS server assigned VLAN.
• If 802.1X is disabled on the port, it is returned to the congured access VLAN.
• When the port is in the Force Authorized, Force Unauthorized, or Shutdown state, it is placed in the congured access VLAN.
• If an 802.1X port is authenticated and put in the RADIUS server assigned VLAN, any change to the port access VLAN conguration
does not take eect.
• The 802.1X with VLAN assignment feature is not supported on trunk ports, dynamic ports, or with dynamic-access port assignment
through a VLAN membership.
