Configuring a free IP
Follow these guidelines when you configure a free IP:
When a free IP is configured, the EAD fast deployment is enabled. To allow a user to obtain a dynamic IP address before passing 802.1X authentication, make sure the DHCP server is on the free IP segment.
When global MAC authentication, Layer-2 portal authentication, or port security is enabled, the free IP does not take effect.
If you use free IP, guest VLAN, and Auth-Fail VLAN features together, make sure that the free IP segments are in both guest VLAN and Auth-Fail VLAN. Users can access only the free IP segments.
