Configuring EAD fast deployment

Overview

Endpoint Admission Defense (EAD) is an HP integrated endpoint access control solution, which enables
the security client, security policy server, access device, and third-party server to work together to
improve the threat defensive capability of a network. If a terminal device seeks to access an EAD network,
it must have an EAD client, which performs 802.1X authentication.
EAD fast deployment enables the access device to redirect a user seeking to access the network to
download and install EAD client. This function eliminates the tedious job of the administrator to deploy
EAD clients.
EAD fast deployment is implemented by the following functions:

Free IP

•
•

URL redirection

Free IP
A free IP is a freely accessible network segment, which has a limited set of network resources such as
software and DHCP servers. An unauthenticated user can access only this segment to download EAD
client, obtain a dynamic IP address from a DHCP server, or perform some other tasks to be compliant
with the network security strategy.
URL redirection
If an unauthenticated 802.1X user is using a web browser to access the network, the EAD fast deployment
function redirects the user to a specific URL, for example, the EAD client software download page.
The server that provides the URL must be on the free IP accessible to unauthenticated users.

Configuration prerequisites

Enable 802.1X globally.
•
Enable 802.1X on the port, and set the port authorization mode to auto.
•

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 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.
