Configuring the EAD assistant feature
When you configure the EAD assistant feature, follow these restrictions and guidelines:
• You must disable MAC authentication and port security globally before you enable the EAD
assistant feature.
• To make the EAD assistant feature take effect on an 802.1X-enabled port, you must set the port
authorization mode to auto.
• When global MAC 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 the free IP
segments are in both guest VLAN and Auth-Fail VLAN.
• To allow a user to obtain a dynamic IP address before it passes 802.1X authentication, make
sure the DHCP server is on the free IP segment.
• The server that provides the redirect URL must be on the free IP accessible to unauthenticated
users.
• To avoid using up ACL resources when a large number of EAD users exist, you can shorten the
EAD rule timer.
