I have 4 ESXi servers in 2 locations here connected via Etherchannel to Cisco Switches with trunking enabled on the wires. I have all network setup properly (at least I think so) because the virtual machines inside the ESXi Servers are working flawlessly.
Only the management console makes me worry. I debugged it today a but further and saw that the console either lost the default ipv6 route (readding default route solved this) or the ipv4 stack can't ping the default gateway (which is pingable in my network). Therefore I have no outside connectivity from/to the remote console.
~ # esxcfg-route -l

anyone got an idea, what's wrong? Is there any possibility to see the arp table? My network guy here suspects an arp-table issue.
Which kind of load balancing policy are you using at vSwitch level and/or at Port Group level?
