Hi,

I have a Cisco 4503 with the Fiber SFP port and say at a 500 meter distance I have a Cisco 3560G switch,I have multimode fiber between these switches,

now Can configure the port as a trunk port.

My guses is for trunking ,it is a layer 802.1q,there is no need to worry about the physical layer.Please clarify my doubts.

Thanks and Regards,

S.Venkataraman.

Hi Venkat,

You probably have an 1000Base-SX SFP module. It is OK for 550m distance.

Yes, you can configure it as a trunk port, similarly to this:

interface gig0/1

switchport

switchport trunk encapsulation dot1q

switchport mode trunk

Cheers:

Istvan
