I want to ask, I send the udp packet to others, if the other side of the board to do the function of arp reply, udp, I only set the IP address and port, to succeed? If not, how to solve?

CodePudding user response:

What do you and across the board through the network connection?

CodePudding user response:

1, do you contract out is to use equipment or instrument, contracting out the equipment contract need to manually write static ARP table entries, configuration method of static ARP table entries using commands vary depending on your device, according to the equipment baidu came out,
2, if your contract equipment is chip, you will need to write the chip's table, this will need to consult the chip detailed FAE,
3, if is the use of instrument contract, directly to the instrument, MAC address is added to the message if this case no forwarding message mostly for calibration of the chip MAC address, so I need to write it 10-channel DMAC message to end port's MAC address,

Note: manual writing table item need the IP address of the corresponding MAC address written on the board interface corresponding MAC address,
Only in the confirmation to end the board not inspection 10-channel DMAC=interface MAC address can be casual MAC address,

Opposite the fpga board through Wan Zhao net PC connected, and I use an xcap fill the destination MAC address and the source MAC address, can communication, I want to know if in the program is just need to bind a static MAC address?

Add that the ARP is to service the corresponding relationship between the IP and MAC, and dynamic agreement, if there is no ARP, or ARP suddenly can't use, so you have to manually configure an IP and MAC corresponding relation, the hope can help you
