In a recent project that I am doing I have 2 cisco 3750G switches straight out of the box, two TFOCA boxes, two SX-MM, two Orange fiber patch cables and two yellow fiber patch cables.
Now the setup that i have looks kinda like this:
Switch1 --- Gbic --- Orange fiber -- TFOCA --Tactical Fiber -- TFOCA --- Orange fiber --- Gbic --- Switch2
192.168.1.2 /24 192.168.1.3 /24
Each GBIC is plugged into G1/0 which is the GBIC slot on both switches. I have each port set to Trunking:
sw trunk encap dot1q
sw mode trunk
no shut
When I go to each switch and type show cdp neigh I see the other switch on both switches. But when I go into Switch 1 and try to ping the other switch it goes through, but when I go into switch 2 I cannot ping the other. I know its a simple problem, but for some reason I cannot get it to work. here is the trouble shooting that I have done below:
Traded out the orange fiber patch cable with the yellow.
Light test on all Fiber which went though.
Traded out GBICS
Traded out multiple Orange/yellow fiber patch cables.
swapped TX to RX on one switch at a time.
Swapped GBIC slots on both Switches
With my knowledge I have troubleshooted as much as I know, but still cannot get Switch 2 to talk to Switch1. its something simple that I'm overlooking, but I have no idea what it is.
