Cisco C3560 Switch using an SFP to connect via fibre to a Linksys SRW2048
Hi,
I have an issue that I am trying to resolve. I am trying to connect a Cisco C3560 Switch using an SFP to connect via fibre to a Linksys SRW2048 with another SFP.
When I connect the two together no lights show up on either side. If I connect the linksys to another linksys with the same SFP and fibre, the link comes up stright away.
If I set the port on the cisco switch side to "speed nonegotiate" the link comes up on the cisco side, but nothing on the linksys side, no lights on the switch nothing.
I have gone through the linksys switch and everything looks ok, but I am doing something wrong.
What am I doing wriong?

Your kidding, of course I checked that the ports are up. It is not a router it is a switch and there is an ip address on the VLAN. Your proposed output would be seen on a router.
Now you have commented, others who actually may have something intelligent to say will not want to comment.

Interface IP-Address OK? Method Status Protocol
Ethernet0 10.108.00.5 YES NVRAM up up
Ethernet1 unassigned YES unset administratively down down
Loopback0 10.108.200.5 YES NVRAM up up
Serial0 10.108.100.5 YES NVRAM up up
Serial1 10.108.40.5 YES NVRAM up up
Serial2 10.108.100.5 YES manual up up
Serial3 unassigned YES unset administratively down down
Indicates the status of interface. Valid values and their meanings are:
•up—Interface is administratively up.
•down—Interface is administratively down.
•administratively down—Interface is administratively down.
ensure both the linksys and the cisco has a ip address. ensure you type the no shutdown on the cisco port. also use this command 'show service-module <the interface> performance-statistics 30-32' to see the performance of the port.
hope this helps.
