Hello. If you had a .pcap file with the least number of packets required to reproduce the issue I could use that to create a unit test and fix this issue.
from packetnet.
You may add a test at LldpTest.cs
like this:
[Test]
public void AsPayloadTest()
{
PhysicalAddress NDP_MULTICAST =
new PhysicalAddress(new byte[] { 0x01, 0x23, 0x20, 0x00, 0x00, 0x01 });
LLDPPacket lldpPacket = new LLDPPacket();
lldpPacket.TlvCollection.Add(new ChassisID(NDP_MULTICAST));
lldpPacket.TlvCollection.Add(new PortID(PortSubTypes.PortComponent, BitConverter.GetBytes(6633)));
lldpPacket.TlvCollection.Add(new TimeToLive(120));
lldpPacket.TlvCollection.Add(new EndOfLLDPDU());
// reparse these bytes back into a lldp packet
//lldpPacket = new LLDPPacket(new ByteArraySegment(lldpPacket.Bytes));
EthernetPacket ethernet = new EthernetPacket(NDP_MULTICAST, NDP_MULTICAST, EthernetPacketType.LLDP);
ethernet.PayloadPacket = lldpPacket;
var bytes = ethernet.Bytes;
Assert.NotNull(bytes);
}
It throws NullReferenceException
. After uncomment that "reparse" line, the test would succeed. I don't know if I shouldn't call methods in that way...

Hi @UlyssesWu. I'm closing this out as it has been open for a while now but we appreciate you reporting it. We would love to have a PR to help resolve this issue and add a test for this case, we just haven't had the time to resolve it here.
