Why do I have to manually 'Restart Management Network' on vSphere 5 host after reboot to get networking available?
- by growse
I've got a couple of vSphere 5.0 hosts in a small lab environment here and I've noticed a strange behaviour. When on of the hosts gets rebooted, it is unresponsive to the network until I log into the ESX console, Press F2 to customize and select Restart management network. Once this is done, the networking works perfectly as expected.
Each host has two NICs which are trunked together using Etherchannel to a Cisco 3750. The link is also a .1q VLAN trunk and the management network is configured on VLAN121 with the VM traffic configured on VLAN118.
Why would the host be completely dead to the world until I physically kick it?
Edit
Sample switch config for trunk:
interface Port-channel2
description Blade 1 EtherChannel Trunk
switchport trunk encapsulation dot1q
switchport mode trunk
end

interface GigabitEthernet4/0/1
