issue in cisco 3750 switch..

[Debudas123]

i have a IBM server(have giga ethernet) which is directly connected with 3750 giga switch...

i facing this.

1. when i have configure the switch port as auto, then data transfer is very slow between switch and the server.

2. when i have configure the switch port as 1000mbps full , then data transfer is going very good but not contunue.

3. when i have configure the switch port as 100mbps full, then data transfer is going very good and its continue.

  i have also change the server's ethernet port as the same steps .. and the result is same...

  so what is the issue..?

Thanking You

Auto-negotiation (duplex) can be the culprit.

Dear

when it is running 1000 mbps, then no chance to mismatch the duplex, because 1000 mpbs does not support half-duplex... so what i'll do.

is it server port problem ?

thanks

hi ,

whenever you change the port settings of 3750 switch , check the duplex using show interface command..

most probably as soon as you change the port settings , duplex of switch could be chaning to half ..

Hi Debudas,

I guess, your IBM server does NOT support 1000mbps speed.

please check with the vendor once.

Thanks
