Mac Address Appear in multiple hosts

Jay Chang
Level 4
Level 4

Hi,

I am seeing Mac address for my VM's appearing on all the hosts in the cluster.  Is this normal behavior? 

We are running ESXi4.1 with VSM 4.2(1)SV1(4) on the Nexus 1010 appliance.  Any help on this would be appreciated.  Thanks.

This is normal behavior.

The MAC addresses are propogated to all VEM hosts so they know whether the VM is local or remote to the host.  You'll notice that each MAC will be "static" on the actual host its running on, and "dynamic" on every other host.

Robert
