Thanks
Karan
 
Hey !!! What sort of network settings do u want to change?
Do u want to change IP address or just tune the existing one????
 
Hi Naveen,

I have installed Solaris 8 on 420R. I wanted to tune the network settings. When I am running the SE toolkit , I am getting the following message. It is droping the more packets. It is not the problem with network, because the same system is running fine with 2.6.

AGGREGATE NETWORK INFORMATION

Overall state of the network interfaces:

black Problem: network failure
Errors seen, fix hardware or cables

State Name Ipkt/s Opkt/s Err/s Coll% NoCanPut/s Defer/s
black hme0 36.4 13.7 0.53 7.56 0.00 0.00

TCP measures Total Rate/s
Input bytes 12928 718.22

ETHERNET RULE THRESHOLDS

ENET_ERROR_PROBLEM default=0.050/s getenv=0.050/s
ENET_DEFER_WARNING default=2.00% getenv=2.00% some delayed output packets
ENET_DEFER_PROBLEM default=10.00% getenv=10.00% too many delayed output packets
ENET_NOCANPUT_PROBLEM default=1.000/s getenv=1.000/s incoming packet dropped by IP

Please give me the solution

Thanks

Hi,
From your message it looks that there are a lot of collisions between packets.
Try to find out the network settings on your server with the following commands (for hme interface):
ndd -get /dev/hme link_speed(1=100mbps,0=10mbps)
ndd -get /dev/hme link_mode(1=full duplex,0=half duplex)
If u find out that your system defaults to 10Mbps(half duplex) then u can force it to work at 100Mbps(FD) with the following commands:
ndd -set /dev/hme instance 0
ndd -set /dev/hme adv_100fdx_cap 1
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_10fdx_cap 0
ndd -set /dev/hme adv_10hdx_cap 0
ndd -set /dev/hme adv_autoneg_cap 0
Then see the network stats with 'netstat -i' command and look for Oerrs and Collis.
If u still find problem then reply back.

I hope u will find this helpful.....
 
Hi naveen

Thanks for your help, I have tryied with that, even I am getting same kind of report. Is there any chnages to done on Solaris 8, It was working fine with 2.6, After installing solaris 8, we are facing this kind of problem, even no users are connected and there is no trafic also.
If you have any idea, Please reply me back.

Thanks for your help

Hey,
What I think is, your router may stiil be working at 10Mbps.U should ask your N/W guys to force the speed of router to 100Mbps instead of auto-negotiable.Secondly, there may be some problem with your network card also.
 
Hi Navin,

Thanks for your reply, the system is connected to 100Mbps.
I am expacting that While installing I was selected IPv6, but the IPv6 is not using. Here is the output of the ifconfig -a.

Do u have any idea, How to disable the IPv6 on solaris 8?

lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 3.61.128.207 netmask fffffc00 broadcast 3.61.131.255
ether 8:0:20:bf:b8:fe
lo0: flags=2000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6> mtu 8252 index 1
inet6 ::1/128
hme0: flags=2000841<UP,RUNNING,MULTICAST,IPv6> mtu 1500 index 2
ether 8:0:20:bf:b8:fe
inet6 fe80::a00:20ff:febf:b8fe/10

Thanks for your help

Hi,
To disable IPv6 give the following command:
ifconfig lo0 inet6 down unplumb
ifconfig hme0 inet6 down unplumb

I hope this helps.....
