Wake-on-LAN Traffic

The Wake-on-LAN feature is used by network administrators to remotely power on a sleeping workstation (for example, during early morning hours to perform routine maintenance operations, such as patch management and software updates).

The aaa port-access controlled-direction in command allows Wake-on-LAN traffic to be transmitted on an 802.1X-aware egress port that has not yet transitioned to the 802.1X authenticated state; the controlled-direction both setting prevents Wake-on-LAN traffic to be transmitted on an 802.1X-aware egress port until authentication occurs.

NOTE:

Although the controlled-direction in setting allows Wake-on-LAN traffic to traverse the switch through unauthenticated 802.1X-aware egress ports, it does not guarantee that the Wake-on-LAN packets will arrive at their destination. For example, firewall rules on other network devices and VLAN rules may prevent these packets from traversing the network.
