I have 2 Catalyst 3560 PoE-48 Linked with the SFP ports, I was trying to go from another one of the SFP ports to the router a Cisco 2821 using a Gigabit SFP transceiver MGBT1. I am not sure if the transceiver is incompatible with the switch or if I am missing a step to get the transceiver to power up. I am trying to clear some bottle-necks in my LAN to WAN connection. The network currently has the 2 switches to a 2821 router then it was going through another switch (took it out of the system, Fordstar equipment no longer needed at the dealership) then to a 2801. I am thinking I should be able to go straight from the switches to the 2821 and straight to the T1 shelf (3 T1's). Am I way off base or is this reasonable. Any Suggestions?
I have this problem too.
