Healthy Network Configuration.

[brian_31]

Hi All:

We are having couple of Nclass servers and users connect from the PC thru WAN and run xmotif apps thru xemulator. Now what are the parameters/files that i should check to make sure that my network configuration is healthy. Currently we used sniffer and the traffic is heavy. Environment 11.0, Nclass,64 bit, MCSG with lan0 thru lan4.Please Advise.

Thanks
Brian.

Have you used lanadmin to verify the speed of your cards, and for other potential problems, like IO errors?

X applications are typically network pigs. What kind of emulation package are you using on your PC's.

Have you checked your system to see if you need any patches?

How many connections do you have?

In most of the cases it has been seen that, though the network card is 100 Mbps , it is working at 10 Mbps. Set the switch port as 100 Mbps and set the Server side also as 100 Mbps fixed.

Hope it helps.

Hi,

Also check out the netstat statistics for each protocol.

# netstat -s

Note however that these statistics are cumulative. You would want to note the rate of increase in the statistics, in particular the inbound and outbound errors.

Hope this helps. Regards.

Brian,

Looking at the output from the lanadmin display for each of your cards should give you the stats you are interested in. You can also verify the speed and duplex for each card with lanadmin -X
The PPA for a card is usually the lan card # e.g. 0 for lan0, 3 for lan3 etc.

If you suspect some kind of network link problems, tts also sometimes helpful to check the nettl log file(s). By doing this, you will see if your getting any messages from the 100BaseT cards (besides cable disconnects). Format the log with /usr/sbin/netfmt -vf /var/adm/nettl.LOG00 > temp-file00 There is also a .LOG01 with older events.

Hope this helps,

Hi All:

Thanks. I am not having any problem right now. But i need to know whether my network configuration is good and how do i check that.
The cards are configured for 100Mbps, no cable disconnects and currently there are about 175 users connecting from all over usa from PC's across WAN.

Thanks
Brian.

Brian,

Do a lanscan and get the PPA number
then do a

lanadmin -x ppa-number

to find what your network card settings are.

Make sure your switch port setting matches
what your network card is. In my shop, we always set to 100FD. To keep the setting permanently, modify the speed to 100FD in the
appropriate hpxxxxxconf file. Hope this help.
