MX65 vlans not working

[DPringle3]

I have a MS120 => to MX65 with vlans setup, when I set a port on the MS120 to an access or trunk, the computer is unable to contact the mx dhcp server and doesn't get an ip.

Hi @DPringle3 

I believe we are missing some configuration. Could you please recheck the following?

1. DHCP Server is enabled on the MX VLAN

    ->Security & SDWAN->DHCP->VLAN-> Client addressing

2. The Port connected between MX & MS120 is in "Trunk Mode"

    ->Security & SDWAN->Address & VLAN-> Per-port VLAN Settings

3. The Switch Port at MS120

   ->Switch->Switch ports->Switchport->Type=Access->VLAN= VLAN ID

shouldn't I be able to ping the gateways of the other subnets, currently I am unable to.

definitely you will be. where are these gateways configured  on MX65 ? if not then you need to put the static route in your mx pointing towards other device in the same subnet that tells you the path to reach to other network.

MS120 port should be in access when it is going to computer. MS120 is L2 switch so you have to define the VLAN in MX65 by going into 

Step 1: Security & SDWAN>Address & VLAN>  Add VLAN

Step 2: Now go to Security & SDWAN->Address & VLAN-> Per port VLAN setting and it should be trunk depend upon Native vlan you have configured like 1 or any

Step 3: Now configure the DHCP scope by Security & SDWAN>DHCP and run a DHCP server for selected vlan.

Now the MS120 part

Uplink to MX 65 will be trunk.

go to Switch> DHCP servers & ARP  and enter the MX65 mac address in Allowed DHCP servers box.
