Question

Connecting a physical port and a vlan interface

Hi everyone,

 

This may be a very simple question that is well documented and I may just be using the wrong search terms but either way I have not succeeded in finding how to do this.

 

I would like our Out Of Band Management switch to be connected directly to our firewall while I also still need to let the vlan "flow" through the downlink to the backbone to be available to virtual management server etc.

 

The thing is I can only add an interface with an address to one of the links and it seems that traffic also doesn't pass between them.

I drew a simple schema of what is happening:

 

I can't create x.x.x.1 twice that I understand but how do I make the vlan on both ports behave as if they are truly 1 vlan where the forti answers/forwards on both and traffic passes from one to the other like any other L2 segment?

 

Thanks!

    Am I aksing this in the wrong subsection every time? (I noticed I already asked it once in a different part of the forum)

    Maybe one of the more experienced folks can answer, but I'm pretty sure what you're asking is not possible.  There would be no point in using the "out-of-band" management if you also need it to be in-band.  Only certain models have an OOB mgmt port anyway. I'd open a support case if you want a better answer / reason why.  They don't monitor this forum.  You might try Reddit also as it seems to be better monitored (both by FTNT and by experienced folks).

    Hey lobstercreed, thanks for your answer!

     

    From your answer I see I amy not have stated my case properly, as far as the forti is concerned it is being managed "in-band" and the question is not about managing the forti but rather about the management vlan which exists on the stand-alone switch but I also want available on the backbone this is so that on the one hand all OOBM/IPMI/{UPS,PDU,env}-management is available on a switch that is directly connected to the forti and thus does not depend on the proper functioning of any other equipment but on the other hand I do have VMs that I want to connect into this network to monitor the status of all of these devices.

     

    I guess I will be opening a support case.
