Only 1 input cable for all vlans

[Jonas Palm]

I have a catalyst 3650-X switch and im setting up a netwotk with multiple vlans. The problem is that i dont want to have 1 cable pr vlan but just 1 cable that vcan deliver network to all my vlans. I tried using a trunk port but it only gives network to its native vlan. Can anybody tell me what im doing wrong?

[balaji.bandi]

as per the information you have allowed VLAN 1, 10 20 from the switch side, what is the other device and what config do you have other side?

when mentioned it only works native vlan (I take here as vlan 1) if other switch port belong to VLAN 10 or 20, they should be working ?

Again we need more information, what is other side device, where is Layer3 interface for all VLAN ?

[MHM Cisco World]

you give us info about one side what about other side, 
you config the port as trunk but are it work as truck ?

show interface x/y switchport 
this give you is the port is trunk or not (share if you can)

[Richard Burts]

The original poster asks "Can anybody tell me what im doing wrong?". We do not know nearly enough about what you have done to be able to suggest what might be wrong. What you have posted shows that there is a switch port configured as a trunk and carrying vlans 1, 10, 20 and that the trunking appears to be working (at least at layer 2). What we do not know includes:

1) what is this switch connected to on the trunk port? Would I be correct in guessing that it connects to some layer 3 device that is intended to supply routing for the 3 vlans?

2) If I am correct that the switch connects to some layer 3 device then how is this device configured?

3) Do devices in vlan 10 receive an IP address? If so are they able to ping their default gateway?

3) Do devices in vlan 20 receive an IP address? If so are they able to ping their default gateway?

Sorry i have forgotten to look here🤦‍ Pretty stupid when im asking a question. But im here now and i will try to answer your questions

First of all the trunk port is connected to the fiber box we get outr network from now. So its just an extention to the existing network.

You are right that it's connected to a layer 3 device but i cant check its configuration because its meant for use and not configuration (by the user)

vlan 10 and 20 can ping their default gateway (192.168.10.1 and 192.168.20.1 ant they can also ping 192.168.1.1 witch is the ip og the trunk port / vlan 1. But not out from the network.

You can see my whole config here. I made a few changes in it but i cant get it to work (i dont work in cli on a regular basis)

woops this reply was meant for another comment.

[MHM Cisco World]

I run small lab 
in IOU1 and IOU2 you need 
interface x/x
switchport truck encap dot1q 
switchport mode trunk <<-this need 
switchport trunk native vlan 1 

in IOU1 and IO2 
you need to add vlan to database by 
vlan 10
vlan 20 

that it.
and it work.

[Jonas Palm]

Oh that seems pretty straight forward. Thank you. But I’m not sure what an iou is and I don’t think what I can find on google makes sense. Can you give a quick explanation on what it is?

[MHM Cisco World]

IOU is L2 image of GNS3VM.
