With your current ifconfig down test, is “options cf.takeover.on_network_interface_failure” set applicably?

Hello, I've got a 3240 HA pair running 7.3.5. We are looking to enable cluster failover for network interface failures. I want to test this with 7.3.5 line of the simulator.
I can create a HA cluster with the simulator. The problem is that both nodes of the sim use the same interface on the underlying OS. I would like node1 of the sim to use eth1 and node2 of the sim to use eth2. That way I can simulate a network failure of just one of the nodes of the sim. I have not found a way to achieve this yet.
I tried creating 2 separate sim nodes (without clustering) on different interfaces, but after they are both up, the cluster interconnect is missing -- so enabling cf does nothing.
Any ideas on how I can do this with the sim?
I tried just doing an "ifconfig ns0 down" on one of the nodes of the cluster-- that disconnected the network from that node, but it didn't trigger the cluster failover, so I'm guessing that an ifdown is not the same as a nic failure (at least as far as triggering a takeover is concerned).
Thanks. Paul
