an anyone please instruct me how to connectCcisco router 1002f SFP ports to gigabit ports?

I have an RJ45 port on switch side and an SFP port on router side. I like to use switch as dump switch. I haven't configured anything I also have RJ45 connector when I try to connect them I see ports administrative down on router side. is there any special connector do I need?

    Put one end of the cable in each device? You really should provide more details on what you're actually trying to achieve, which problems you're running into, what configurations you're using, etc. As it is, we can only guess what information you're looking for. – Teun Vink Mar 13 '18 at 21:29
  • Hey Teun, I apologizes for that. I have rj45 port on switch side and sfp port on router side I like to use switch as dump switch. I haven't configured anything I also have rj45 connector when I try to connect them I see ports administrative down on router side. is there any special connector do I need ? – patrick Mar 13 '18 at 21:34

You must use an SFP module and cable that is of the same standard as what you have on the switch. That is probably a GLC-T SPF module. You insert the SFP module in the SFP interface and connect the cable between the devices.

You must also configure the interfaces. Typically, you will either enable routing on the switch and configure a routed interface, or you will configure it as a trunk and configure subinterfaces on the router.

  • Hi Ron, I do not have sfp cable. I have cat5 cable to use. so basically one side of sfp ports and one side of gig ports i belive we need rj45 connector and i also i have one but i am still unable to connect them. – patrick Mar 13 '18 at 22:34
  • What I am saying is that if you use the correct SFP module, you use your cable between the router and switch. You need an SFP module for your SFP interface. – Ron Maupin Mar 13 '18 at 22:36

  • OK, then you should be able to use a standard UTP cable between the router ans switch. Simply configure the interfaces for how you need them. – Ron Maupin Mar 14 '18 at 0:09
  • do I need that converter on both side or just on router side? – patrick Mar 14 '18 at 21:10
