B-52 APPENDIX B: CLI COMMAND DESCRIPTION
TCP COUNTERS
Active Opens - number of times TCP connections have made a direct
transition to the SYN-SENT state from the CLOSED state
Passive Opens - number of times TCP connections have made a direct
transition to the SYN-RCVD state from the LISTEN state
Attempt Fails - # of times TCP connections have made a direct transition
to the CLOSED state from either the SYN-SENT state or the SYN-RCVD state
& the # of times TCP connections made a direct transition to the LISTEN
state from the SYN-RCVD state
Resets - # of times TCP connections made a direct transition to CLOSED
state from either ESTABLISHED or CLOSE-WAIT states
Currently Established - number of TCP connections for which the current
state is either ESTABLISHED or CLOSE-WAIT
Input Segments - sum of segments received
Output Segments - sum of segments sent, including those on current
connections but excluding those containing only retransmitted octets
Retransmitted Segments - sum of segments retransmitted
show tcp settings Displays system-wide TCP settings.
TCP SETTINGS
Retransmission Algorithm - for example, Van Jacobson
Minimum Timeout - minimum retransmission timeout interval
Maximum Timeout - maximum retransmission timeout interval
Maximum Connections - sum of TCP connections allowed. If maximum
number of connections is dynamic, the value is -1.
show udp Displays statistics for UDP datagrams.
INPUT COUNTERS
Total Input Datagrams - sum of UDP datagrams received
Input but No Port - sum of received UDP datagrams for which there was
no application at the destination port
Input with other Errors - sum of received UDP datagrams that could not
be delivered for reasons other than the lack of an application at the
destination port
OUTPUT COUNTERS
Total Output Datagrams - sum of UDP datagrams sent
