Command Response IP status
code code
Twelve types of IP status information occupying 4 bytes each are returned in
the following sequence. Each value is returned as an 8-digit hexadecimal
value.
1. Total number of IP packets received.
2. The number of IP packets discarded due to an error with the checksum in
the packet header.
3. The number of IP packets discarded because the received packet was
larger than the overall packet length value in the packet header.
4. The number of IP packets discarded because the minimum size of the IP
header data could not be stored in the first short buffer (See note.) when
an attempt was made to store the packet. Refer to 7-3-26 MEMORY STA-
TUS READ and Appendix B Buffer Configuration.
5. The number of packets discarded for one of the following reasons:
• The IP header length value in the IP header was smaller than the
smallest size of the IP header.
• The size of the first short buffer (See note.) was smaller than the IP
header length value in the IP header when storing the packet.
