Can Meraki Layer 3 Switch (MS225-48LP) Create Vlans

[Marlon]

Hi Team, 

This may be a dumb question but I haven't got any confirmations yet. Can Vlan be created on Meraki Layer 3 Switch? 

I have a MS225-48P Switch, it's saying this Switch is a Layer 3 Switch that can do DHCP-Relay. See below for example I create an Interface for Vlan e.g.24 but his Vlan 24 is not created on MX Firewall. If I apply this interface setting on this Vlan, will this Vlan be created and existing on the Network or not? 

Thanks. 

Regards,

Marlon

Hi @Marlon , yes, you can create L3 VLANs on these switches.  However, it won’t create the vlan on the MX which I think is what you’re asking?

In both MS and MX you cannot create a layer 2 VLAN, as you only noticed layer 3, so if you need this VLAN in the MX you need to create a layer 3 interface in the MX too, otherwise you can work with routes.

Thanks, how to create a layer 3 interface in MX? Please also see what I just added on my first question and see if you can help? Thanks.

Maybe it will help you.

When you say "create a Layer 3 Interface in the MX", I assume you mean create a Static Route to route the Vlan subnet to a Layer 3 Interface?

Hi @DarrenOC , Thanks. Let me describe what I want to achieve on MS225. 

I want to create a new Vlan e.g.24 by creating an Interface on MS225, and setup a DHCP Relay to MX Firewall. On MX, I setup a Static Route to go to Vlan 24 Subnet via the IP of MS225, and I Enable DHCP on this Static Route with the Gateway of the Interface created on MS225. 

Vlan 24 is not created on MX, I want this MS225 to create Vlan 24 and apply DHCP Relay to MX. Is this logic correct? Any issues?

Sounds fine,

I think you also should set the tracking to uci

Hi @ww @alemabrahao , I think I find a right article (MX and MS Basic Recommended Layer 3 Topology)

to describe my scenario. In this topology the Vlan is created on layer3 Switch only and not go through MX. I think this is what I want. Thanks anyway.
