Constructor Detail

OVXLLDP

public OVXLLDP()

Instantiates a new OVX LDDP message.

Method Detail

setSwitch

public void setSwitch(Switch sw)

Sets switch DPID in LLDP packet.

Parameters:

sw - the switch instance

setPort

public void setPort(Port port)

Sets port in LLDP packet.

Parameters:

port - the port instance

serialize

public byte[] serialize()

Serializes full LLDP packet to byte array. Need to set both switch and port before you can serialize.

Specified by:

serialize in interface IPacket

Overrides:

serialize in class LLDP

Returns:

a byte[] containing this packet and payloads

isLLDP

public static boolean isLLDP(byte[] packet)

Checks if LLDP packet has correct size, LLDP multicast address, and ethertype. Packet assumed to have Ethernet header.

Parameters:

packet -

Returns:

true if packet is LLDP, false otherwise

isOVXLLDP

public static boolean isOVXLLDP(byte[] packet)

Checks if packet has size of OVX-generated LLDP, and correctness of two organizationally specific TLVs that use ON.Lab's OUI. Assumes packet is valid LLDP packet

Parameters:

packet -

Returns:

parseLLDP

public static DPIDandPort parseLLDP(byte[] packet)

Extracts dpid and port from OVX-generated LLDP packet.

Parameters:

packet -

Returns:

Dpid and port
