TCP: keepalive
Keepalive check cycle.
TCP: connects
Total number of connections established.
TCP: closed
Total number of dropped connections.
TCP: timeoutdrop
Total number of dropped connections due to
TCP retransmission timeout. If the
transmitted packet (the unit of transmitted
data) is not received, the packet is
automatically retransmitted at a
predetermined time interval. If the packet is
not received after 14 retransmissions,
timeout occurs and the connection is
dropped.
TCP: keepdrops
Total number of dropped connections due to
TCP keepalive timeout.
TCP: sndtotal
Total number of transmitted packets.
TCP: sndbyte
Total number of transmitted bytes.
TCP: sndrexmitpack
Total number of retransmitted packets.
TCP: sndrexmitbyte
Total number of retransmitted bytes.
TCP: rcvtotal
Total number of received packets.
TCP: rcvbyte
Total number of received bytes.
DLC: 16 collisions
Number of collision incidents. A collision
occurs when two or more devices on the
network attempt to transmit simultaneously.
The tendency for collisions to occur
increases when the network is congested.
16 collisions would mean 16 consecutive
collision incidents.
quit Disconnects the connection of
the device being operated
