Release Information

Statement introduced in JUNOS Release 9.0 for EX Series switches.

Statement added to the [edit services captive-portal interface] hierarchy in JUNOS Release 10.1 for EX Series switches


Configure the method used to authenticate clients for 802.1X or captive portal authentication.




single—Authenticates only the first client that connects to an authenticator port. All other clients connecting to the authenticator port after the first are permitted free access to the port without further authentication. If the first authenticated client logs out, all other supplicants are locked out until a client authenticates again.

single-secure—Authenticates only one client to connect to an authenticator port. The host must be directly connected to the switch.

multiple—Authenticates multiple clients individually on one authenticator port. You can configure the number of clients per port. If you also configure a maximum number of devices that can be connected to a port through port security settings, the lower of the configured values is used to determine the maximum number of clients allowed per port.
