FTD Transparent Mode (TRUNK)

[MarkNode17]

Scenario....

I have 2 switches (Switch A and Switch B), they are connected together via a TRUNK allowing vlan 10 and 20 to traverse between them.  I want to insert an FTD between the switches in transparent mode.  I'm having a heck of a time finding documentation or an example of how to do this when the switches are connected via a trunk.  Doing this with a routed link between routers is easy and its also easy if the link between the switches was an access port with a single vlan, then I'd use a BVI.  I've messed around with the configuration in FMC for hours and haven't been able to come up with anything that works.  Anyone have any experience with this? 

Any help would be greatly appreciated.  

Thanks,

Mark

I will start one by one but It can work or it can not there is some limitations 

But anyway let try

1-Device-> device management 

Click edit (for your FTD)

Interface page will appear 

There is switchport columns 

Make slider enable.

2-the interface we make it switchport click edit

In edit physical interface 

In general config your native and allow vlan

3- add vlan interface 

4-config bridge group inlcude vlan interface 

Hope this help you 

Good luck
