Network is fine all other servers r working fine and NIC card i checked no problems. when ever it connects it works with good speed. But why it got disconnects ?

Hi,

Use the below command to find out network errors like cable disconnection and timeout errors.

# netfmt -Nlf /var/adm/nettl.LOG000

Hi Vinod ,

seems like an Ip address conflict to me ,
ping
arp -a
netstat -in....check with networking team.

Regards ,
Rahul

[Jitesh purohit_1]

Have you done any changes in the past with your server or your network team did any changes

Thanks
Jitesh

[Steven E. Protter]

Shalom,

The older errors indicate that either the LAN card is a problem or requires a re-seat, or the network cable is bad and should be replaced, or there is a problem with the network switch port physically or its settings.

All of these things should be checked.
