niping test in a IBM DB6 DPF environment

Hi Team,

Wanted to test the communication between nodes in a DPF environment.

When i checked the niping options. I dont see an option using pvlan. Because if we use normal tests then it wouldnt be using the pvlan and the tests will fail right. If we are checking the communication between data node and admin node?

Test Program for NI-Layer (network interface), Version 40, January 14 2008

running modes
start server     niping -s
start client     niping -c
self test        niping -t
verify nodeaddr  niping -v
interface list   niping -i
MAC address list niping -m

additional options
-H hostname    name of server-host                   (default localhost)
-S service     service-name or port-number           (default 3298)
-K sncname     SNC-name server                       (default no SNC)
-B bufsize     size of data-buffer                   (default 1000)
-L loops       number of loops                       (default 10)
-V tracelev    trace level (0 - 3)                   (default 1)
-T tracefile   name of trace file                    (default stdout)
-I idle time   maximum idle time                     (default 300 sec)
               t > 0  shutdown after t secs idle
               t = 0  no automatic shutdown
               t < 0  shutdown after -t secs idle or
                      first client disconnect (server only)
-R             raw mode
-P             detail print


expert options
-N timeout     for completion of fragmented packages (default 200 msecs)
-O             one way mode
-Q maxbytes    fragment test mode
-D delay       delay between sends                   (default 0 msec)
--acl_file=acl-file  # load 'acl-file' (server mode)
--acl_check          # load and check acl and exit


Check network connection between host A and B on NI-level
---------------------------------------------------------

Start niping as a server (option -s) on host A. Then start
niping as a client (option -c) on host B.

The client sends <loops> packets of size <bufsize> which are
echoed by the server. The client then displays the average,
maximum and minimum round trip time.


Check the basic functionality of the NI-layer
---------------------------------------------

To perform a self test on the local host start niping with
option -t. The last line of the output should contain
"*** SELFTEST O.K. ***" if no problems occured.

Hi Team,

Has anyone tested in a DPF environment. What are your recomendations.

Hi,

I am not aware of that option, usually customers for DPF run

niping -c -H <server> -B 1 -L 100

Hi,

the default value for -B bufsize is recommended (1000)

Hi Javier,

Thanks a ton for the information. It did help and we did ran the tests. Thanks so much for the help.

Hi,

If you want just checking communication, the default 1000 bytes buffer size would be ok, but for measuring throughput, larger value would be better: 8 000 000, like stated within the OSS note #500235 - Network Diagnosis with NIPING:
