Assuming unicast.
If you are going to cluster with a single NIC, you have to use multi-cast, which gets more complicated. Regards, Michael B.

The active MAC address will be based on which node currently has the cluster IP assigned to it. Whichever NIC that node has on the correct subnet for the cluster IP will supply the mac address. If you want multiple nics on a node to be able to handle it, you should team the nics, which creates a virtual team nic which has its own mac address.

One or more used at a time??? ----- Original Message ----- From: Damien Solodow <mailto:[email protected]> To: MS-Exchange Admin Issues <mailto:[email protected]> Sent: Monday, January 05, 2009 12:18 PM Subject: RE: Does IP is at layer 3, you need a MAC so layer 2 devices (like switches) can pass the traffic. It looks like the cluster IP address is assigned as an additional IP on the configured NIC in the server. So the cluster mac address will vary based on which node currently owns it.

You *have* to have a MAC address for IP doesn't work.

From: Kat Collins [mailto:[email protected]] Sent: Monday, January 05, 2009 12:07 PM To: MS-Exchange Admin Issues Subject: Re: Does There is the Host IP, the Windows Cluster IP, the Messaging Cluster IP, and the Heartbeat IP (which must be on a different subnet other than the one where the rest of the IPs reside) as well as the Remote Management IP (Rilo/DRAC) which should also be on a separate subnet...
