Method Detail

inPort

org.onosproject.net.ConnectPoint inPort()

Returns:

connect point

packet

org.onlab.packet.Ethernet packet()

Gets the full parsed representation of the packet.

Returns:

ethernet header

protocol

NeighbourProtocol protocol()

Gets the protocol of the packet.

Returns:

protocol

type

NeighbourMessageType type()

Gets the message type of the packet.

Returns:

message type

vlan

org.onlab.packet.VlanId vlan()

Gets the vlan of the packet, if any.

Returns:

vlan

srcMac

org.onlab.packet.MacAddress srcMac()

Gets the source MAC address of the message.

Returns:

source MAC address

dstMac

org.onlab.packet.MacAddress dstMac()

Gets the destination MAC address of the message.

Only valid for reply packets, will be null for request packets.

Returns:

target MAC address

target

org.onlab.packet.IpAddress target()

Gets the target IP address of the message.

Returns:

target IP address

sender

org.onlab.packet.IpAddress sender()

Gets the source IP address of the message.

Returns:

source IP address

forward

void forward(org.onosproject.net.ConnectPoint outPort)

Forwards the message to a given output port.

Parameters:

outPort - output port

forward

void forward(Interface outIntf)

Forwards the message to a given interface.

The message will be modified to fit the parameters of the outgoing interface. For example, if the interface has a VLAN configured, the outgoing packet will have that VLAN tag added.

Parameters:

outIntf - output interface

reply

void reply(org.onlab.packet.MacAddress targetMac)

Replies to the request message with a given MAC address.

Parameters:

targetMac - target MAC address

flood

void flood()

Floods the incoming message out all ports except the input port.

drop

void drop()

Drops the incoming message.
