Hello!
Is it possible to create redundant interface for subinterfaces or is it only available for physical interfaces?
I have one ASA connected to two C3750 which are stacked, and few VLANs that are connected to ASA's subinterfaces via trunk.
Thanks!

As soon as you assign a physical interface as a member interface, all the parameters related to that interface will be cleared, including sub interfaces, security level, nameif,etc... However, if you want to configure sub-interfaces (dot1q), you can do
that on top of the redundant interface(s), not the physical interfaces.In other words, member interfaces need to be physical interfaces which cannot have sub-interfaces underneath.

Thanks for the information.
Can you tell me how to configure sub-interfaces on top of the redundant interface. I couldn't find any documentation regarding that type of configuration.
That's the main reason why I taught it isn't possible.
Thanks in advance!
Kind regards,
