Compound Authentication Modern networks employ many authentication methods. The Compound Authentication methods supported by this Switch include 802.1X, MAC-based access control (MAC), Web-based Access Control (WAC), Japan Web-based Access Control (JWAC), and IP-MAC-Port Binding (IMPB). The Compound Authentication feature allows clients running different authentication methods to connect to the network using the same switch port. The Compound Authentication feature can be implemented using one of the following modes: Any (MAC, 802.1X or WAC) Mode In the diagram above the Switch port has been configured to allow clients to authenticate using 802.1X, MAC, or WAC. When a client tries to connect to the network, the Switch will try to authenticate the client using one of these methods and if the client passes they will be granted access to the network.

In the above diagram the Switch port has been configured to allow clients to authenticate using 802.1X. If the client is in the IMPB table and tries to connect to the network using this authentication method and the client is listed in the white list for legal IP/MAC/port checking, access will be granted. If a client fails one of the authentication methods, access will be denied. 243

Compound Authentication

Compound Authentication settings allows for multiple authentication to be supported on the Switch.

Compound Authentication

Modern networks employ many authentication methods. The Compound Authentication methods supported by this

Switch include 802.1X, MAC-based access control (MAC), Web-based Access Control (WAC), Japan Web-based

Access Control (JWAC), and IP-MAC-Port Binding (IMPB). The Compound Authentication feature allows clients

running different authentication methods to connect to the network using the same switch port.

The Compound Authentication feature can be implemented using one of the following modes:

Any (MAC, 802.1X or WAC) Mode

In the diagram above the Switch port has been

configured to allow clients to authenticate using 802.1X,

MAC, or WAC. When a client tries to connect to the

network, the Switch will try to authenticate the client

using one of these methods and if the client passes they

will be granted access to the network.

Any (MAC, 802.1X or JWAC) Mode

In the diagram above the Switch port has been

configured to allow clients to authenticate using 802.1X,

MAC, or JWAC. When a client tries to connect to the

network, the Switch will try to authenticate the client

using one of these methods and if the client passes they

will be granted access to the network.

802.1X + IMPB Mode

This mode adds an extra layer of security by checking

the IP MAC-Binding Port Binding (IMPB) table before

trying one of the supported authentication methods. The

IMPB Table is used to create a ‘white list’ that checks if

the IP streams being sent by authorized hosts have

been granted or not. In the above diagram the Switch

port has been configured to allow clients to authenticate

using 802.1X. If the client is in the IMPB table and tries

to connect to the network using this authentication

method and the client is listed in the white list for legal

IP/MAC/port checking, access will be granted. If a client

fails one of the authentication methods, access will be

denied.
