Real problems negotiating the CISCO and site and presales haven't been too helpful so perhaps somebody here can help.

Situation: dark fibre channel connection coming into a location, going from the FC MUX (Gb) to a Cisco 2960 Switch (not sure what model). The rest of the switch has 10/100 ports on them and they go into the patch panel to distribute throughout the office.

Have a team that want Gb ethernet connectivity over the WAN. Not sure how to enable that. I am guessing that existing Cisco switch can't do it since it appears to have only one Gb port (uplink) which is used to connect to the WAN. So perhaps I need a small Gb switch I can connect the 2960 downstream to (Gb) and patch that switch to the port that the team that wants Gb connections, while patching a 10/100 port on that switch to the inbound port on the 2960?

Does that make sense?

Any other ways I could do this?

Thanks for any ideas or pointers

There are many different versions of the 2960 switch - you can see a model comparison here:
http://www.cisco.com/en/US/products/ps6406/prod_models_comparison.html

If you do a "show ver" in IOS you can identify exactly what model it is. As you can see from the above link, most of the 2960s do have 2x gigabit ports. If possible it would be prefereable to use the 2nd gigabit port to feed another switch for the users who require gigabit.

If you do only have a single gigabit port on the cisco, Putting a gigabit switch in between the Cisco and the mux would most likely work, however it could easily become the limiting factor especially if it's a consumer grade switch. You would also need to check that it is one single LAN and there aren't VLANs trunked over the uplink, a consumer grade switch could possibly break that.

Thanks. Did some more investigation and found that there is another switch a 2950 we have which has a spare port on it. So with some adroit patching we can connect the outlet to that port through some daisy chaining. No VLAN's that I am aware of
