Abstract
Techniques to inspect packets to determine a destination node are provided. In one aspect, a Wake on Lan (WOL) packet may be received at a switch. A destination node of the WOL packet may be determined. An indication of the determined destination node may be sent to a management controller. The management controller may cause the destination node to awaken.
Claims18
A method comprising:
- receiving a Wake on Lan (WOL) packet at a switch coupled to a first network in a system including the switch, a chassis including a plurality of nodes, a management controller coupled to the switch via a management network isolated from the first network, wherein the switch is separate from the chassis, the switch connects one or more of the plurality of nodes to the first network, a communications channel connects the plurality of nodes to the switch, the switch connects the plurality of nodes to the first network via the connection of the plurality of nodes to the switch by the communications channel, and the switch isolates the management network from the communications channel;
- determining, at the switch, a destination node of the WOL Packet, wherein the destination node is one of the nodes and wherein the destination node includes a System on a Chip (SoC);
- sending, by the switch, an indication of the destination node to the management controller via the management network isolated from the communications channel;
- and
- in response to the indication, causing, by the management controller, power to be supplied to the SoC,
- wherein the management controller causes the determined destination node to awaken.

A non-transitory processor readable medium containing thereon a set of instructions, which when executed by a processor of a switch, cause the processor to:
- inspect incoming data packets of a first network for the presence of a magic packet,
- wherein the switch is communicatively coupled to a chassis, which is external to the switch, that includes a plurality of nodes via the first network,
- wherein the switch is communicatively coupled to a chassis manager via a management network isolated from the first network, the switch connects the plurality of nodes to the first network, a communications channel connects the plurality of nodes to the switch, the switch connects the plurality of nodes to the first network via the connection of the plurality of nodes to the switch by the communications channel, and the switch isolates the management network from the communications channel;
- determine a destination node of the plurality of the nodes for the magic packet, wherein the destination node includes a System on a Chip (SoC) and is communicatively coupled to the first network;
- and
- send an indication of the determined destination node to the chassis manager via the management network isolated from the communications channel,
- wherein the chassis manager causes the determined destination node to power on by causing supply of power to the SoC.

A system comprising:
- a chassis including a plurality of nodes;
- a first node of the plurality of nodes, the first node including at least one network interface identifiable by an address;
- a first communications channel;
- a switch separate from the chassis coupled to the first node through the first communications channel, wherein the switch to inspect incoming packets searching for a Wake on Lan (WOL) packet destined for the first node, the switch connects the first node to a first network via the coupling of the first node through the first communications channel, and the switch isolates a second communications channel from the first communications channel;
- and
- a Management Controller (MC) to receive an indication from the switch over the second communications channel that the WOL packet for the first node has been received, wherein the MC to cause the first node to power on.
