TCP Connection Statistics

B-D-C

 

 

When you press Return on the TCP Data Statistics screen, the TCP Connection Statistics screen is displayed, showing a summary of the TCP connection activity on all interfaces that terminate on the DSL card.

connection requests ± Number of TCP connections initiated by a process on this card.

connection accepts ± Number of TCP connections accepted by this card.

connections established ± Number of connections established.

connections closed/dropped ± Number of connections closed (normally) including those dropped.

embryonic connections closed ± Number of connections dropped before data transfer.

segments updated rtt ± Number of packets that updated the Round Trip Time (RTT) and the total number of times TCP attempted to update the RTT.

retransmit timeouts ± Number of times a packet had to be transmitted because it was not acknowledged and the number of times a connection was dropped because a packet could not be transmitted.

persist timeout ± Number of times the TCP persistence timer went off and sent a probe to the remote system.

keepalive timeouts ± Number of times a TCP keepalive request timed out.

keepalive probes sent ± Number of TCP keepalive probes sent.

connections dropped by keepalive ± Number of connections dropped because the keepalive timer failed to get any responses.

IP Statistics

B-D-D

 

 

Displays a summary of the IP activity on all interfaces that terminate on the DSL card.

total pkts rev ± Total number of IP packets received by this card, with errors broken down on the right of the screen.

fragments rev ± Number of packet fragments received, with dropped fragments on the right of the screen.

packets were fragmented on transmit ± Number of packets that were fragmented on transmit.

packets were received on transmit ± Number of packets that were fragmented on transmit and the number of fragments that were created by those packets.

packets forwarded ± Number of packets that were forwarded to another system.

packets not forwardable ± Number of packets that could not be forwarded. (Usually due to packet errors or routing problems.)

packet redirects sent ± Number of redirect messages sent to other systems because they sent a packet that should not be sent to this card.

network broadcasts received for local networks ± Number of network broadcasts received for local networks.

network broadcasts forwarded by media broadcast ± Number of network broadcasts forwarded by media broadcast.

network broadcasts partially processed ± Number of network broadcasts dropped due to an error.
