Dropping 50% of Packets on network

[Guest_imported]

Hello PPl
I'm having a very strange problem with one of my intel solaris server. It takes me long time to connect with that server, after i find out it is droping almost 50% of its network packets.
sending 100 packets of length 86 to solaris ...
26 packets (26.000%) dropped by solaris
4 packets/sec, 423 bytes/sec
Can someone tell why this happening and how to fix that problem.
Thanks

are you using cisco's? thay have problems with auto sync and solaris box's sometimes set speed to 10 or 100 respectively.

I am using Netopia ethernet router,and it should not be a problem, cause i tried other router instead still having the same problem. My wise guess goes with interface card or related, but i have no clue how to check interface card status. please someone guide me how to check the status of interface.
Thanks

Try using the netstat command to check for Inbound and
outbound errors. For example:

# netstat -I hme0

This would give you inbound and outbound errors, collisions


And try to see if you are set for full duplexing:

If you have an hme or le interface use this: Example is
for an interface called ( hme0 )

# ndd -get /dev/hme instance 0

1
------------------------------------------
1 is full duplex
0 is half duplex

I got the following result form
netstat -I elxl0
Name Mtu Net/Dest Address Ipkts Ierrs Opkts
elxl0 1500 192.168.1.0 solaris 8819 2686350413
Oerrs Collis Queue
7741 0 0 0

I am getting no device driver error runing
ndd -get /dev/elxl instance 0
Also, why i'm geting Net/Dest address as 192.168.1.0 however, my server Ip is 192.168.1.16

Sorry the ndd command is:

# ndd -get /dev/elxl instance

This should return the ndd value.

Is your server called solaris?
