Dual DHCP helper-address in startup-config

Hi,
Here are the answers to your questions.
Question 1:
The ip-helper address is used for DHCP relay. You can also add this via the GUI, under "System" --> "Services" --> "DHCP Relay" --> "UDP Relay".Question 2:
The command vlan participation include will untag a vlan that on a given port (note, it will not set the PVID though). The command vlan participation exclude will remove vlan association on a given port.In the config file, you don't see the vlan include command for vlan 1, even though all ports are untagged for vlan 1 - as you mention. This is because that is the default setting. A config file only shows you what deviates from the default settings and since include vlan 1 is default on all ports, it won't show you that in the config file. Just like pvid 1 is set on all ports per default and you don't see that in the config file either.
Cheers
