Hi Anil

Can you check your logs in your 3560 Switch ?

Logs will provide vital details for your to troubleshoot what might be going wrong in your switch.

You can check out the same using show log command in your switch..

do make sure that you have enabled logging before using the command show log.

Hello Anil,

is the 3560 a gigabit enabled one ?? check if there are any speed/duplex mismatches between the switchport and the server.. you can run auto/ auto or best thing is to force the speed/duplex to 100/full... Check this and let us know... also enable "portfast" on the switchport to make sure the switch comes online soon....

All the best...
