No that won't work.
If you are configuring cDOT, at least two ports per controller are reserved for the cluster network (e0a & e0c)
This leaves e0b and e0d available for normal network access

The recommended configuration is to use all four ports for the cluster network (e0a, e0b, e0c & e0d).
In this case, if you need/want 10gig network connections you would need an extra 10gig card

AS indicated earlier in this thread, from each controller:
a0a should be a multimode_lacp VIF and contain:
e0b -> switch 1
e0d -> switch 2

Then you can create your VLANs: a0a-123, a0a-456 

Place your LIFs on the tagged VLANs

Create a failover group for node-01:a0a-123 and node-02:a0a-123
Create a failover group for node-01:a0a-456 and node-02:a0a-456

Assign the failover group to the appropriate LIF

PS: DO NOT FORGET to disable spanning tree on the switch ports.
--> spanning tree protocol should only be enabled on ports connected to other switches.
--> it is not needed on ports connected to en hosts
--> in a cluster failover event it could take an extra 45 seconds for a port to become available.(not good)
--> remember to use the right version of the command. if it is a trunk, you usually need that on the line

You can also tie the four links into a single interface group and carve it up into multiple VLANs.

What ports are you going to use for the cluster interconnect?  I assume you’re ordering a switchless cluster of two nodes?

We are looking to buy new FAS8040 and configure it with CDOT. I am looking for network recommendation with Cisco 6509 VSS. 8040 has four 10G ports per controller and I want to use all four ports to create an interface group with two VLAN, using VLAN tagging. I want 2 ports to go to one VSS switch and 2 ports to go to other VSS switch so I have switch redundancy also. I am not sure if it is doable since I am going to two different switches. Any recommendation is appreciated.
