Internal Failover configuration

Hi All,

I would like to implement failover capabilities to my internal network. Waiting to buy another asg 220 in the next few months, I would like to provide failover cap to internal net. In depth:

My internal ASG 220 ip is:192.168.3.200/24
I have 2 ESXi Server, both connected to one cisco 3550. I bought another 3550 and I will stack both(Actie/standby cluster).

So my question is:

Can I connect 2 Astaro interface, one to the primary cisco and second to the other cisco, in a way that internal ASG inteface will be available in a case of switch failure?

I thought to bridge 2 Astaro nic and convert them to internal interface.
Also, tell me(please), if I need to change something on Packet rule, etc...

Thank you.
