Parameters
IP Status (Response)
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
4. The number of IP packets discarded because the minimum size of the IP header data could not be stored
5. The number of packets discarded for one of the following reasons:
6. The number of IP packets discarded because the IP header length was larger than the overall packet length
7. The number of fragmented packets received.
8. The number of received fragmented IP packets discarded because a queue for reassembly could not be
9. The number of fragmented IP packets discarded because they could not be reassembled within 12 seconds
10. Always 0.
11. The number of packets addressed to other networks that have been discarded.
12. Always 0.
Note Refer to MEMORY STATUS READ on page 411 for details on the short buffer.
ICMP Status (Response)
Ten types (46 items) of ICMP status information occupying 4 bytes each are returned in the following
sequence. Each value is returned as an 8-digit hexadecimal value.
1. The number of times the ICMP error routine was called. The ICMP error routine uses ICMP packets to inform
2. Always 0.
3. Always 0.
4. Total number of outputs of each packet type during ICMP output. The 19 statistical values are returned in
