Hello all,

I preparation for my Google fiber install I will need to set QoS for the traffic going out wan2 of my 90D. Would anyone be able to help me figure this out? I have't messed with QoS much. According to Google, all traffic needs to be tagged as follows:

[ul]

DHCP traffic should have 802.1p bit = 2

IGMP traffic should have 802.1p bit = 6

All other internet traffic 802.1p bit = 3[/ul]

Any assistance would be greatly appreciated.

Where are you getting that at? "802.1p" is for 802.1q tagged interfacs, are you running vlans into goog-fiber?

I am basing off of information here https://support.google.com/fiber/faq/3333053

and http://flyovercountry.org/2014/02/google-fiber-gigabit-speeds-your-router-part-2-qos/

[strike]Well according to the page it basically means you need to route your DHCP traffic to VLAN 2, IGMP traffic to VLAN 6 and all other internet traffic to VLAN 3[/strike]

Did you ever ask goog support on this and yes the fortigate has no means that I'm aware of for COS and layer2 QoS. You need a switch but I really dont understand where you getting your information at.

e.g

Setting a COS value for IGMP, that traffic location typically ttl=1, never goes anywhere but to a multicast group(s) and once again locally.

Hey travise, I found a solution if you are interested. You do NOT need a managed switch.

You have to create your three QoS rules as IPv4 Policies and then use the CLI to assign "vlan-cos-fwd" to each of the three policies. I posted the detailed solution on my blog here: [link]https://will.mx/google-fiber-with-fortigate-90d/[/link]
