<TCPIP>
command displays a summary table of statistics of ICMP, IP and TCP protocols,
i.e., packets processed by the internal INT interface.
RR_01_PM>TCPIP
-- TCP/IP Statistics ------- ICMP ------- IP -- IP Frag ------ TCP ------------
Transmitted packets: 0 1487 0 1159
Retransmitted packets: 0
Received packets: 0 2245 0 1787
Forwarded packets: 0 0 0
Dropped packets: 0 0 0 0
Checksum error: 0 0 0 0
Invalid length error: 0 0 0 0
Out of memory error: 0 0 0
Routing error: 0 0
Protocol error: 0 0 0 0
Error in options: 0 0
Misc error: 0 0 0 0
-------------------------------------------------------------------------------
RR_01_PM>
The column ICMP shows the ICMP operation, the column IP shows statistics of the IP protocol,
the column IP frag displays the operation with fragmented IP packets and the column
TCP displays the statistics of the TCP protocol.
Transmitted packets
– the number of transmitted packets.
Retransmitted packets
– the number of retransmitted packets. Not applied to IP and IP Frag.
Received packets
– the number of received packets.
Forwarded packets
– the number of forwarded packets. Not applied to TCP.
Dropped packets
– the number of dropped packets.
Checksum error
– the number of packets with the checksum error.
Invalid length error
– the number of packets with an invalid length error.
Out of memory error
– the number of packets out of memory of the device TCP/IP stack.
Routing error
– the number of routing errors when transmitting packets.
Protocol error
– the number of packets with protocol errors and with limitations imposed by the
protocol.
Error in options
– the number of IP packets with the invalid field “options”.
Misc error
– the number of other errors.
Option: С – update the table continuously.
Note: The system does not calculate statistics over all ICMP packets passing through network
interfaces of the modem. Calculation is performed only over packets forwarded to the
internal network interface of the modem: broadcast and multicast packets, and packets
used in telnet, SNMP, WEB.
