Hi, hoping someone can help with this irritating problem I've got!
My current office has 5 x Cisco 3650 switches stacked together (via stacking module) that services what I will call Office-A. I need to connect these via OM4 MM fiber cable to a new floor space 150 feet away which I will call Office-B. This office has 2 x 3650's stacked via stacking module again. Checking the interfaces Office-B's switches they can see each other ok, so I'm using Cisco branded SFP's to connect the fiber back to Office-A with the below configuration from Office-B's switch-1 to Office-A's Server switch:
#vtp mode client
#interface t1/1/1
#switchport mode trunk
#switchport trunk allowed vlan all
#switchport trunk native vlan 1
#no shutdown
However I cant get a connection to form between the stacks. I know the fiber is working ok (a Netgear switch is able to connect instantly to its neighbour without any problems) so what am I missing? I've attached a crude Visio of what I'm attempting.
Many thanks
Solved! Go to Solution.

the 10gbs should work 3650s don't support the other type
I believe these mods are the same as 3850 and theres specific pisrt for 10gb have you tried the below if your 10gb ?

Hi
Are the interfaces up/up on both sides yes ? can you post them
if there up do you see cdp between them ? and if up what does show int trunk provide each side
09-13-2016 05:47 AM
Hi Mark, no the interfaces arent up at all. The status lights are dead and dont respind when I plug the SFO's in. I know the fiber works as a netgear switch used for lining the voip networks between office (on fiber patch port 3) works ok. When I plug the Cisoc switches into that port on either end they stay dead.

great good stuff :)
09-14-2016 01:56 AM
HI, fixed it! I had the sfp in port 1 instead of port 3 or 4 which is for 10gb modules. As soon as I plugged it in there it came up!

Hello
If your configuration is correct and you still have no physical connection - Try swapping the fibre strands of the fibre cable around at one end of the connection
