Hi fpmurph,
For thanks for your reply and information.
you are correct. In our network, two server were having same MAC address (as mentioned in my previous post).
Below are the steps that we performed to resolve the issue:
->First network admin disable the port that is used by sql01 for MAC(all actiivty performed on one server at one time).
->Then we checked for duplicate error in Test01 server and test03 server.
->Error were not coming.
->Once n/w team enable the port again on sql01 server, then we again start recieving the same error on both sever.
->We tried to reboot both sql01 and sql03 server. But after when sql server comeup, error was still these.
->This time network admin tried to clear the ARP table for specific MAC address and we rebooted the sql01 server.
->View the errpt log in test01 server. Now we were not receiving "Duplicate IP detacted in net".
->Same step we followed for othese sql03 server and after another AIX server(test03) also was not receing error in errpt command.
->We check with our network team for reasoning.
->According to them, there was no issue with switch becuase switch only use to contain server MAC ans related IP address.
->That is the window server(sql01 and sql03 server) that was causing issue by generating same MAC address as AIX server.
->Still I am not sure about the reason which cause the sql machine to generate same MAC address.
->Last weekend window team did patching on Window server.
->Now our database and application are running fine.
Request you to all folks, if any one know baot the reason how window server can generate same MAC address as other machine or what are the situation, where this situation occure. Kindly update on this post.
Thnaks & Regards,
