TOP Tips – TCP/IP

TOP – Not just a Pretty Face for NonStop!

by: Matt Riesz

TOP is a great GUI for just about everything you need to do on your NonStop system. One of the most helpful features is the ability to easily look at data communications information, especially as it pertains to CLIM IP, or “CIP”.


Let’s suppose that you want to see who is using TCP/IP on your NonStop system, and what programs are listening for incoming connections on a particular IP address, and which IP ports they’re using. Seems simple, right? But even if you do this on a frequent basis and can recall all of the SCF commands involved, it can be a tedious and time-consuming task:


First, find all of your CLIMs:

TACL> SCF
1-> assume process $ZZCIP
2-> status clim *

CIP Status CLIM

Name                     Config              State            Trace
NCLIM000                 Yes                 STARTED          OFF
NCLIM001                 Yes                 STARTED          OFF
SCLIM000                 Yes                 STARTED          OFF
SCLIM001                 Yes                 STARTED          OFF
SCLIM002                 Yes                 STARTED          OFF

Note that the command returns both IP CLIMs and Storage CLIMs. So, pick an IP CLIM and look at the detailed status. There’s a LOT of information:

3-> status clim NCLIM000, detail
CIP Detailed Status CLIM \PAPEX.$ZZCIP.NCLIM000

                             IPv6: ::1

Interface Failover Configuration and Status:
Flg  Name         Failover/(Assoc) Fovr  Current          Provider
NCLIM000.eth3                      --    NCLIM000.eth3    ZB03C

NCLIM000.eth1                      --    NCLIM000.eth1    ZB018

NCLIM000.eth2                      --    NCLIM000.eth2    ZB02D

Now you have the information needed to find out which IP addresses are associated with which interface on that CLIM. But who is using those addresses?


Next, find all of the CIPSAM processes – These are called “Providers” in CIP, and are the processes that your program accesses when it wants a connection. Each provider is associated with one or more CLIMs, and there may be more than one provider for a given CLIM:

4-> status provider *
CIP Status PROVIDER
Name       Status     TPStatus  Trace

ZB018      STARTED    Started   OFF
ZB01C      STARTED    Started   OFF
ZB02D      STARTED    Started   OFF
ZB02E      STARTED    Started   OFF
ZB03C      STARTED    Started   OFF
ZB03D      STARTED    Started   OFF
ZTC0       STARTED    Stopped   OFF
ZTC1       STARTED    Stopped   OFF
ZTCP0      STARTED    Started   OFF
ZTCP1      STARTED    Started   OFF

Well that wasn’t too hard. Next, find out which provider is associated with the IP address you’re interested in:

5-> status provider zb018,detail
CIP Detailed Status PROVIDER \TICX.$ZZCIP.ZB018

                                  IPv4: 43.4.5.243
                                  IPv6: fe80::32e1:71ff:fe6a:6e91

NCLIM000.eth1  UP   UP                    --   --   NCLIM000.eth1 --

You might need to look at all the providers to find the one you’re looking for. But great, now we know which CLIM, interface and IP address is driven by this provider. Now, enter another command to find all of the listeners and established sessions through the provider for that interface:

There may be a LOT of listeners and sessions, appearing in no particular order in the SCF output and, as you can see, it’s not very easy to read. So next you copy the output from your screen (or log it to a file and copy that) into a spreadsheet, separate it into useful columns of information, and sort it to find what you’re looking for.


That all will probably take you about 15 minutes if you know the commands by heart or maybe an hour or more if, like me, you have to read through the SCF manuals looking for them.


A great alternative is to use TOP:

Sign on to TOP and select your system. The system’s components appear in a familiar,  Windows-Explorer-style interface

Navigate to “Comms”, “TCP/IP”, “IP CIP”


TOP now shows the available IP CLIMs. Select one, and click on its “Interfaces”. You now see the CLIM’s interface information, including which providers are using them and which IP addresses are being served:

Now click on “Providers”. Top shows information on all the providers:

Next, right-click on a provider and select “Sockets” from the pull-down menu. TOP provides information for all of the current active sockets for that provider:

Sort it however you want by clicking on a column heading. For example, by Foreign IP Address, to see who has an active session:

Total time to do this with TOP: about 1 minute, and you don’t need to know any command syntax. Information from the TOP display can also be easily copied and pasted into your favorite spreadsheet.  It’s EASY!
