IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). By "port" we mean a single point of attachment to the LAN infrastructure. It provides an authentication mechanism to devices wishing to attach to a LAN, either establishing a point-to-point connection or preventing it if authentication fails.

User interface

The 802.1X configuration is done from the IP-station web interface at Advanced Network > 802.1X.

IEEE 802.1X configuration page


Choose authentication method. The different authentication methods are:

  • MSCHAPV2
  • MD5
  • TTLS with PAP
  • PEAP with MSCHAPV2
  • TLS

MSCHAPV2 and MD5 encrypts the password.
TTLS with PAP and PEAP with MSCHAPV2 encrypts both username and password.

Depending on the authentication method there are a few parameters to configure.

  • 802.1X status: Enable or disable 802.1X
  • Username: The username used to identify a station.
  • Password: The password associated with the username.
  • Fake username ["TTLS with PEAP" and "PEAP with MSCHAPV2" only]: The fake username sent outside of encrypted tunnel with TTLS with PAP and PEAP with MSCHAPV2. The user name is encrypted.
  • Verify server with certificate [TTLS with PEAP, PEAP with MSCHAPV2 and TLS only]: Specifies that the client verifies that server certificates presented to the client have the correct signatures, have not expired, and were issued by a trusted root certification authority (CA). It's enabled by default.
  • Fast Re-Authentication:
  • Get new DHCP on success: If 802.1X authentication is successful, station will restart it's DHCP client.
  • Insert CA Certificate [TTLS with PEAP, PEAP with MSCHAPV2 and TLS only]: Upload certificate (public key) used by authentication server. This is not required if "Verify server with certificate" option is disabled.
  • Insert User Public Certificate [TLS only]: Upload certificate (public key) used by authentication client (user).
  • Insert User Private Key [TLS only]: Upload the private key which is paired with user public certificate.


  • Click Save to save the current settings
  • Click Reboot. The new 802.1X settings will only come into effect after a reboot.

802.1X and software upgrade

Software upgrade is not possible when a station is using 802.1X authentication.

In order to upgrade the station, one must either:

  • Remove security on the switchport, upgrade and set security back on the switchport.
  • Connect the station to a non-802.1X port and do a manual upgrade.

Note that in the Turbine stations the 802.1x certificate does not survive a software upgrade. The certificate must be uploaded to the station again after a software upgrade.

The reason that the station cannot be upgraded is that during the upgrade of the IP-station, 802.1X will not be running. Thus if 802.1X reauthentication is enabled and is performed during upgrade, the IP-station will lose contact with the tftp server (dependent on the configuration when 802.1X authentication fails). If the IP-station loses contact with the tftp server, it will not be upgraded. The same is also valid when upgrading via VS-IMT.

Software requirement

802.1X is supported:

  • In INCA stations as from firmware 1.09.3.0.
  • In Turbine stations in all firmware versions.
  • In Pulse mode as from firmware 4.7 (Turbine) and 2.7 (INCA). (Previously supported only in SIP and AlphaCom mode).
