OMNeT++中使用TsnDevice作中继出现未知协议错误求助

我在OMNeT++中搭建了两个UDP数据包转发网络：

• 第一个采用StandardHost作为中继，运行正常；
• 第二个使用TsnDevice（tsnDevice2设置forwarding=true）作为中继，触发未知协议错误，报错信息如下：

<!> handlePacket(): Unknown protocol: protocolId = 24, protocolName = ethernetmac, servicePrimitive = INDICATION, pathStartGate = combNetwork.tsnDevice2.ipv4.ip.queueOut, pathEndGate = combNetwork.tsnDevice2.ipv4.lp.in[1] -- in module (inet::MessageDispatcher) combNetwork.tsnDevice2.ipv4.lp (id=258), at t=0.00101837s, event #16
