List of MAC address - Dual MAC address for one VM

We have a guest VM on a ESX 3.0.2 with 8 NICS in a virtual switch. On our packet tracing software, it shows the VM is communicating using two different MAC addresses.

How do I get a list of MAC addresses for that host for troubleshooting? I thought it was in Virtualcenter.. but I can't find the MACs.

You can get this information either through powershell using the toolkit or you can pull this straight off the ESX Host for all VMs residing.

#!/bin/sh

IFS=$'\n'

for vm in `vmware-cmd -l`;

do

VM_NAME=`vmware-cmd "$vm" getconfig displayName | awk '{print $3}'`

VM_MAC=`grep ethernet0.generatedAddress "$vm" | awk '{print $3}' | sed 's/\"//g' | head 1 | sed 's/://g'`

echo -e "\t$VM_NAME\t$VM_MAC"

done

unset IFS

This will pull just the first NIC, but you can modify it to pull all MAC's associated with a Virtual Machine on a given ESX Server
