To configure basic server fail fallback options using the CLI:
Configure an interface to allow traffic to flow from a supplicant to the LAN if a RADIUS
server timeout occurs (as if the supplicant had been successfully authenticated by a
RADIUS server):
[edit protocols dot1x authenticator]
user@switch# set interface ge-0/0/1 server-fail permit
Configure an interface to prevent traffic flow from an end device to the LAN (as if the
end device had failed authentication and had been rejected by the RADIUS server):
[edit protocols dot1x authenticator]
user@switch# set interface ge-0/0/1 server-fail deny
Configure an interface to move an end device to a specified VLAN if a RADIUS server
timeout occurs (in this case, the VLAN name is
[edit protocols dot1x authenticator]
user@switch# set interface ge-0/0/1 server-fail vlan-name vlan1
Configure an interface to recognize already connected end devices as reauthenticated
if there is a RADIUS timeout during reauthentication (new users will be denied access):
[edit protocols dot1x authenticator]
user@switch# set interface ge-0/0/1 server-fail use-cache
Configure an interface that receives an EAPOL access-reject message from the
authentication server to move end devices attempting LAN access on the interface to
a specified VLAN already configured on the switch (in this case, the VLAN name is
):
vlan-sf
[edit protocols dot1x authenticator]
user@switch# set interface ge-0/0/1 server-reject-vlan vlan-sf
