We recieve lots of input packet errors. we clear it using lanadmin.
Is there a way to avoid this?
A patch which can take care of this?

any help will be appreciated.

Re: input packet errors
is this down to the machine or a noisy line ?
You could try and lower the connection speed ?

Re: input packet errors

---> yes it is a noisy line. it is a production server.
You could try and lower the connection speed ?
--> can you be more clear with the above point. which parameter should i tweak?
the baud rate.
packet size.
Since i am new to HP-UX i haven't done much research due to limited resources.
thanks

Re: input packet errors
Is the lan card configured to auto-negotiate or is set to 100FD?
Get the PPA from lanscan (look for Card In#)
then run lanadmin -x PPA#
Example: lanadmin -x 0
If there's a mismatch in speed/duplex settings on the server and the switch side it could result in lots of packet errors.
To correct the issue use "lanadmin -X 100FD 0" and update the appropriate file in /etc/rc.config.d/
To figure out which file to modify, run /usr/sam/lbin/laninfo and that'll tell you the btlan or gelan etc. Now modify the /etc/rc.config.d/100btlanconf or the appropriate file to ensure the lan settings are configured in subsequent reboots.

Re: input packet errors
I have got the following o/p from lanscan and lanadmin command.
============================================
[xxxxxx:/]# lanscan
Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI
Path Address In# State NamePPA ID Type Support Mjr#
0/0/0/0 0x001083FF1AA0 0 UP lan0 snap0 1 ETHER Yes 119
0/3/0/0/4/0 0x00306E2564D0 1 UP lan1 snap1 2 ETHER Yes 119
0/3/0/0/5/0 0x00306E2564D1 2 UP lan2 snap2 3 ETHER Yes 119
0/3/0/0/6/0 0x00306E2564D2 3 UP lan3 snap3 4 ETHER Yes 119
0/3/0/0/7/0 0x00306E2564D3 4 UP lan4 snap4 5 ETHER Yes 119
===========================================
[xxxxxx:/]# lanadmin -x 0
Current Speed = 100 Full-Duplex Auto-Negotiation-OFF
[xxxxxx:/]# lanadmin -x 1
Current Speed = 100 Full-Duplex Auto-Negotiation-OFF
[xxxxxx:/]# lanadmin -x 2
Current Speed = 100 Full-Duplex Auto-Negotiation-OFF
[xxxxxx:/]# lanadmin -x 3
Current Speed = 10 Half-Duplex Auto-Negotiation-ON
[xxxxxx:/]# lanadmin -x 4
Current Speed = 10 Half-Duplex Auto-Negotiation-ON
===========================================
The above statistics are from the server side. i don't have access to the hardware. how can i find switch statistics remotely.
Rick:
from the above o/p it is not a 1000Base-T n/w.
And i think there is a duplex mismatch(sorrow) :)
However before taking any action i want to confirm the settings on the switch side.
Any suggestions ?
Thanks and Regards

Re: input packet errors
Per the happiness/lucky/sorrow table, that suggests (to me anyway :) that you should try using auto. If the switch is auto, all should be well. If the switch is hardcoded to half, you will be in the "lucky" space.
If the switch is a "managed" switch, sometimes you can retrieve its stats via SNMP. I believe that HP ProCurve switches have various management software you can run on a PC as well. Both might require knowledge of a magic password set on the switch though.

Re: input packet errors
Thank you for Suggestions.
I have few more doubts.
1. How can i know which nic is responsible for the packet errors.
There are 5 nics with different speed/duplex settings. Some of them are auto some are not.
Shall i assume that the packet errors are due to nics which have autonegotiate OFF.????
2. If the switch is a "managed" switch, sometimes you can retrieve its stats via SNMP. I believe that HP ProCurve switches have various management software you can run on a PC as well. Both might require knowledge of a magic password set on the switch though.
Is there are any link where i can read some info about the point mentioned above.
Regards
Sunny

Re: input packet errors
as for the switch stuff, start at http://www.hp.com/go/procurve for HP ProCurve switches and their manuals etc.
