Words cannot express the appreciation that needs to be given to the
people on this list, from the admins who reply, to the web-site that
store the archives. Thank you seems inadequate.

Special thanks to:

Solution: (See question at end of mail)
Sun replaced the board on the server. The collisions have stopped.

Few things to note when changing the board:
Need a new device tree.
If it gives the following error:
dev/dsk/c0t0d0s1: No such device or address
   The / file system (/dev/rdsk/c0t0d0s0) is being checked.
   Can't open /dev/rdsk/c0t0d0s0
   dev/rdsk/c0t0d0s0: CAN'T CHECK FILE SYSTEM.
   dev/rdsk/c0t0d0s0: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY

boot with cdrom:		boot cdrom -s
mount the disk: 		mount /dev/dsk/c0t0d0s0 /a
moved path_to_inst:	cd /a/etc ; mv path_to_inst path_to_inst.org
boot -a:			accept default and say yes to question
boot -r:			system should come up fine. Check and
verify

Things to try: (admin's replies)
===================================
do a netstat -i
also, you may wish to bring the interface down nad unplumb it
ifconfig le0 down
ifconfig le0 unplumb

ifconfig le0 plumb
then bring it back up
ifconfig le0 inet <ipaddress> netmask <netmask> broadcast <broadcast
address> le0
===================================
I test my Ultra 5 network ports with a crossover cat5 cable connecting
hme0 to hme1 and run "test net" at the ok prompt.  Obviously this
requires two ethernet ports to work, and that you shut your system down
to the ok prompt.  I see this as a basic hardware test and it seems
pretty thorough.  Otherwise I would utilise the package SUNWvts, VTS is
Sun's free validation test suite and we use that to test all of our
hardware.  There is a network section in the vts.  You can find VTS on
one of the supplement cd's of the media kit.  Mine is on the "Software
Supplement For the Solaris 8 Operating Environment", towards the bottom
of the list is "SunVTS 4.0"
===================================
Hi, youve probably allready heard this but the le-interface is 10mb
half-duplex only, so collisions are a common thing. Add a
hme-interface(or
qfe) and run it in 100fdx and you should have no collisions.
===================================
Evidently, ndd does not work with le.  Sorry for misleading you.
Please reference this previous sun manager's list posting:

http://www.netsys.com/sunmgr/1999-07/msg00057.html

In it, Casper Dik mentions that le0 only has one mode, 10Mbit HALF
duplex.
Make sure your switch has the same setting and I would expect your
collision problems to cease.

=====================================

Hi all.
I think I have a faulty network card. I am getting very low responses.
The port the server connects to show a lot of collisions.

Does the following output mean the le0 is damaged?
Does the output reading mean from the machine?
Is there another way to check?

7288/92249 = 8% collisions

bash-2.05# netstat -in 1
