Honored Contributordhcp response for multiple ethernet port application
Hi, there:
I try to build a project with Ethernet daughter card and Altera Startix III DE3 board. I hope both Ethernet ports on the daughter card can communicate with the host PC simultaneously via Telnet. Now, two Ethernet ports on one Ethernet daughter card has been assigned with individual MAC address and static IP address. And I expect the DHCP can initialize both Ethernet interfaces. However, only one port has been initialized. You can see the details from following running result. I carried out some debug, and I found that both Ethernet has sent out it own DHCP request. But the DHCP server only response one request. Therefore, only one Ethernet port get initialized. I am very curious that why the DHCP server can only response these request once. Is there additional setting I need to implement on the DHCP request package? Anyone can give me some suggestion? Thanks. prep_tse_mac 0 Your Ethernet MAC address is 00:07:ed:12:8f:ff prep_tse_mac 1 Your Ethernet MAC address is 00:07:ed:12:0f:8f prepped 2 interfaces, initializing...
