Datatek Applications Inc. 37
reports only connections that are associated with instances, and shows the instance ownership of
each connection. The list is sorted by local port number. The optional -f flag sorts the list by
foreign IP address and port number. The following is a dc app report example:
< DT-6061> dc app
Active Internet Connections by Applications (sorted by local address):
Type Inst FD Local Addr Foreign Addr
b2aprt 10 .5 192.168.8.250.1340 192.168.8.15.31000
tn3270 2 .5 192.168.8.250.10002 135.17.59.198.34052
b2aprt 10 .4 192.168.8.250.10010 135.17.59.198.34054
Note that in the above report, “FD” (file descriptor) is only for use during software development or
troubleshooting.
The connections may also be viewed from an SNMP manager.
6.8.2 DISPLAY MEASUREMENTS – DM OR DMEAS
Syntax: dm|dmeas [ -d ] ip | tcp | udp | icmp | con | eth
The DT-6XXX platform maintains measurements of network activity as an aggregate of all the
application instances. The measurements are grouped into six categories. The measurements for
any one of the categories may be reported by the dm command, giving one of the categories as a
parameter. The categories IP, TCP, UDP, ICMP, and ETH report measurements for that protocol.
The CON report shows the current number of connections. The optional -d reports the differences
between the current measurements and the previous results from dm. There is no way to clear
the measurements.
These measurements may also be viewed from an SNMP manager. Appendix 10 shows sample
reports along with information about the individual measurements for the four protocol categories.
6.8.3 DIAG COMMAND - DIAG
Syntax: diag <subcommand> <parameters>
The diag command reports a variety of reports and statistics from the DT-6XXX console and can
aid in network monitoring and troubleshooting. Using the diag command with no recognized
suboptions results in the message.
diag: Invalid command
