Common Port Provides the interface to the Ethernet IP. This port carries traffic from/to both the Controlled and Uncontrolled ports. The MACsec IP provides up to 64 Common ports.
Controlled Port A virtual access point which provides full access to the network. This traffic requires encryption or decryption. The MACsec IP provides up to 64 Controlled ports.
Uncontrolled Port A virtual access point which provides full access to the network. You must filter the required packets on this port. In the case of the reference design, EAPOL packets are filtered. This traffic does not require encryption or decryption. The MACsec IP provides one Uncontrolled port.
