| sf-slack | <timo.callahan> @pgielda Do you know of any Renode demos that connect sysbus.eth to host.tap? I'm having trouble figuring out how it works. I have set up at TAP interface at 192.168.100.100, and I have the Arty example .resc that loads HDMI2USB, which says its interface is at 192.168.100.50. I connect sysbus.eth and host.tap to a switch in promiscuous mode, and with noisy logging, I see packets forwarded to sysbus.eth. | 07:39 |
| sf-slack | But sysbus.eth doesn't seem to be replying to the ARP protocol ("who has 192.168.100.50? tell 192.168.100.100"). Should I not be using the switch? | 07:39 |

| sf-slack | <mholenko> if you have wireshark installed on the host, you can use it to inspect network traffic inside Renode; in monitor, execute `emulation LogEthernetTraffic` after loading the platform and start the simulation | 09:23 |
| sf-slack | <mholenko> and yes, you should be using `switch` - both the tap device and the platform's ethernet card should be connected to it using `connector Connect` | 09:26 |

| sf-slack3 | <timo.callahan> @pzierhoffer and @mholenko thanks for the tips! The Renode docs are pretty good so I did catch that I need to explicitly start the TAP and the switch if I add them after emulation has started. And I did have wireshark running to look at the external traffic. But `LogEthernetTraffic` is new to me, so hopefully that will help. | 15:19 |

| sf-slack3 | <timo.callahan> @mithro do you know offhand if the LiteEth in HDMI2USB should understand and reply to ARP for IP addresses? I see it pull in the ARP packet ("who has 192.168.100.50? tell 192.168.100.100") but not reply. | 21:11 |
