Re: [lwip-users] what's the mean that ARP can be disabled completely?

SNMP suppose sometimes that netif are all ethernet ones. It would be better to do some changes. But in a first time, I would like to check in this patch file (even if it's not a perfect solution, it marks with some @todo points to review, and enable to build SNMP with LWIP_ARP=0).

If I put LWIP_ARP=0 and ARP_QUEUEING=0, there is 2 errors in mib2.c. I will fix that.

 

So is it your "lot of error" (copy/paster them here)? What I don't understand is you want to use an ethernet device without ARP (which seems a little bit strange). Can you confirm?

Hi,

 

 

    In the web http://lwip.scribblewiki.com/LwIP_version_1.3.0_release_notes, about arp, it's a message:

  

    LWIP_ARP option in lwipopts.h. ARP can now be disabled completely.

 

    According to my understanding, arp can be disabled by setting LWIP_ARP = 0 in lwipopts.h just like LWIP_UDP、LWIP_TCP and so on. I have chaged code in the enthernetif.c that it can be work in my target board. if setting LWIP_ARP = 1, LWIP works well, but if setting LWIP_ARP = 0, it is a lot of error.

 

    So, I want to ask what's the mean about the message in above web! how can I do when I want to set LWIP_ARP = 0?

 

Thanks!
