Fast Initial Link Setup (FILS)

Enable Fast Initial Link Setup (FILS) for 802.1X EAP WLAN and select the realm-based AAA configuration and DHCP server IP address.

Combines the authentication, authorization, and DHCP to reduce EAP frames and skip EAPOL 4-way handshake when station reconnects or roams. It requires AAA to support Higher Layer Protocol (HLP) and EAP-RP. The DHCP server requires the Rapid commit. The following WLAN feature combinations are supported by FILS:

  • 802.1x(FILS) + WISPr
  • 802.1x(FILS) + MAC Auth
  • 802.1x(FILS) + 802.11w
  • 802.1x(FILS) + FT
Note: FILS provides MAC support. When FILS is enabled, the DHCP Rapid Commit Proxy is also enabled by default. However, it is hidden in the screen.
