Hello All,



Is there any one who knows about W3100a'a TCPI/IP Support?


They have mentioned

that they are supporting TCP, UDP, IP, ICMP etc.


But i want the detailed features what they support in TCP/IP.


If any one knows or have some documents please send it to me.


  1. Is this support all of the following features as defined by RFC

1122?


IP (Addressing, TOS, TTL, IP Options, Source Route Option, Routing Outbound Datagrams, Reassembly & fragmentation, Source route forwarding ie Broadcast & Multicast)


ICMP ( Destination Unreachable, Redirect, Source quench, Time Exceeded, ICMP Echo Request or Reply, ICMP Address Mask Request & Reply, Parameter problem, ICMP Timestamp & Timestamp Reply)


UDP (IP Options, UDP Checksums, UDP Multihoming).


TCP (Push Flag, Urgent Data, TCP Options, TCP Checksums, Opening and closing Connection, Retransmission, Acks, Sending Data, Connection Failure, TCP Keep Alive, IP Options, ICMP Messages & Address Validation)


  1. Is WIZZnet ASSP provides feature of Secure Socket Layer (SSL) for TCP and UDP?


Hope a reply from you.

The documentation is on the

WEB site, but I cannot find a specific reference to RFP compliance. All that is stated is

+Hardware Internet protocols included: TCP, IP Ver.4, UDP, ICMP, ARP +Hardware Ethernet protocols included: DLC, MAC +Internal ICMP responds to PING commands

Don't think there is any SSL support.

You just treat the device like a socket interface. All ARPs, checksums, etc. are handled in hardware. I would suggest posting on the support board

to see if you can get more specific information.

You can checkout the FreeRTOS.org WEB site for some sample source code that uses the I2C interface on the device (see link in signature). There is also a live demo but this uses a non standard port number so is often blocked by firewalls, etc.

Hi Richard,

Thanks for your reply. What is the document name in the website which is describing about detailed TCP/IP support? I also sent mails to snipped-for-privacy@wiznet.co.kr .But they are not replying.

If you come across any document regarding this then please let me know.

Best Regards Bhabani
