Hello,
I need to extend the LAN on the 892 to the Catalyst switch via the fiber sfp modules in each unit. I enabled the GigabitEthernet0 port on the 892 and set the medi-type to sfp. What do I need to do to make that port part of the inside network?
I will post configs of both devices if neccesary; I guess I was hoping it would just plug and play!
Thanks!

Yes, post the configs please.

Router config below - it appears that the SFP slot on the 892 is for WAN only? If I try to set switchport mode access on that port, it gives invalid command.

Does the command "switchport" work to enable it for layer 2? What is the show interface details for that interface? 892 is a router correct? A router doesn't carry vlans.
What are you trying to accomplish? Router on a stick?

I am able to use the switchport command on the other interfaces (Fa0-7), but not on Gi0. The 892 is a combination router/switch among other things. I'm trying to use the sfp port which I have inserted a fiber connector to extend the LAN to a switch in a remote location. Is there another way to use the Gi0 interface to pass traffic other than switchport?

I am going to say, just from reading the product details, that the Gi interface is WAN only which means you need to route your traffic. This would make sense since its a SOHO type router/switch.
