I'm currently setting up this 10GbE switchless Config in an test environment and triped over the following:
"For each interface which has enabled Virtual IP address it is required to have enabled Auxiliary connection." - this is an error message you get when you try to start Failover. The problem is: when you do not have a switch in the line, there is no physical link between the members of a Virtual IP Pool. I thought the link would be possible via the vSwitch in ESX, but it looks like that this isn't the case.
Anyway, it turned out the setup is relativly complicated to configure and to wire. Todd, you said you have a customer who is using this setup. Any chance to get a few more infos from him, e.g. are they also using VMware ESX? Do you think there's a chance to get in contact with them?
All the best and glad to hear from you guys.
Best,
Norman
