Hello guys.

I'm having problems with my Cisco FTD 2140, at the moment of enabling the interfaces with SFP module.

In the image below can see that when I enable the interface, it sends me that message.

I'm using the interface Ethernet 1/13 with a SFP module.

Hello @Alen. 

Based on your screenshot and the problem description, you might be hit with this bug.
Could you please try the workaround and see if it solves the problem?

Are you trying to install a 10G SFP or 1G? 10G SFPs are not supported on the 2100 FTDs. However, if you are trying to install a 1G SFP, could you please share the interface hardware settings for review? Also, you can connect to fxos and show the interfaces details including port channels as follows:

- connect fxos

- scope eth-uplink

- show detail expand

Alternatively, if you only want to list the interfaces that are not part of the port channel then you can do this:

- connect fxos

- scope eth-uplink

- scope fabric a

- show interface expand detail


FP 2130 and 2140 does support 10G SFP+ modules.
