The ASA does not support connecting an EtherChannel to a switch stack. If the ASA EtherChannel is connected cross stack, and if the Master switch is powered down, then the EtherChannel connected to the remaining switch will not come up.

 

Colleagues,

Can somebody explain this?

What in means?

If I have ASA 5515x and switch stack 2 pieces   3750 or 3850,

I can not connect ASA G0/1   to switch1 G1/0/1 and ASA G0/2  to switch2 G2/0/1 ?

only VSS supported ?

A stack is one logical switch and the Etherchannel should work with both switches in a stack as well as one or the other. I've connected them successfully like that before. No VSS is needed.
