1218 IP Routing
Wake-on-LAN
The Wake-on-LAN (WoL) feature allows dormant PCs to be powered when
the switch receives a specific Ethernet frame, known as the
magic packet . The
magic packets to wake devices are originated in the network. The switch
needs to:
• Support passing this packet to the destination.
• Process net-directed broadcast packets.
Refer to the
ip directed-broadcast command in the Dell EMC
Networking N1100-ON, N1500, N2000, N2100-ON, N2200-ON, N3000E-
ON, N3100-ON, and N3200-ON Series Switches CLI Reference Guide
.
When a host that uses WoL is attached through an 802.1X port and the host
powers off, the 802.1X port becomes unauthorized. The port can only receive
and send EAPOL packets, and WoL magic packets cannot reach the host.
When the switch uses 802.1X authentication with WoL, configure forwarding
traffic to the unauthorized 802.1x ports, including magic packets using the
command
authentication control-direction. Refer to the Dell EMC
Networking N1100-ON, N1500, N2000, N2100-ON, N2200-ON, N3000E-
ON, N3100-ON, and N3200-ON Series Switches CLI Reference Guide
for
more details. While the port is unauthorized and the
control direction in is
configured, the switch continues to block ingress traffic. The host can receive
packets but cannot send packets to other devices in the network.
