Typical ESXi host-facing switchport configs

Here’s a snippet of what they came back with for two particular ports:
interface GigabitEthernet1/5
description -=R910 ESX# 1 – Front Side=-
switchport mode trunk
end
interface GigabitEthernet1/6
description -=R910 ESX# 1 – Front Side=-
end
Well. Not only do I see our problem (no config *at all* on one port!), but I see something else that troubles me. Our ESXi host-facing ports are only configured as trunk ports. Absolutely* nothing* else. Well, this just won’t do.
