MX-64 and VLANs

[ACETech]

A client has a MX-64 with 4 Meraki APs.

The router is setup with 3 VLANS that I see on the router dashboard.

default   192.168.1.1       /24

Office     192.168.128.1  /24

Public     192.168.254.1 /24

The 24-port switch is a Adtran provided by the ISP.  I do not have access to the switch nor can I get a running config from the ISP.

It was mentioned that the person that setup the MX-64 also did not have access to the Adtran switch.

The Adtran switch (which is POE) has all phones, computers, access points, and printers attached.  The Adtran switch will be removed from the network and will be replaced with a non-Meraki switch.  The Meraki router and access points will stay.

I don't often work with Meraki.  Normally the VLANs are tagged at the switched.  Is this the case?  Or does the Meraki router handle this differently and treats the Adtran as a flat network switch?

Thanks for the help,

Darryl

What am i missing?

No it's still normal vlans. One will likely be native and the other two tagged or all 3 can be set to tagged depending on your config.

You can read about it here: https://documentation.meraki.com/MX/Networks_and_Routing/MX_Layer_2_Functionality

On the MX you can tag (Trunk) the ports without any problems.
See what the documentation recommends when the switch is not Meraki.

@ACETech - what config is it n the uplink port of the MX to your Adtran switch?  That will give you an indication as to what the Adtran may or may not be doing.

[ACETech]

is this what you are asking?  I'm not there today. if you need to know what port from the mx-64 to the adtran i can get that tomorrow.  and thanks!

[DarrenOC]

So all your L3 are on the MX.  As previously mentioned you have a Trunk link down to your switch with all your VLANs allowed.

So this should be a pretty straightforward switch swap out with no intervention required from your side.

Thank you for that clarity.  As I understand what you said - the ADtran probably does not have configured ports for the VLANs.

I see devices with the 192.168.128.n IPs for Office VLan (128).  Don't remember what devices (ap's or other office devices).

Note here this switch (MS220-8P) is located on top of a shelf in the men's bathroom (i just learned). (see picture below).  Does this complicate things?  

(note that i can remove and replace any switch that is causing a clean go-live with the new ISP; we and the client don't have usernames or passwords to switches, only the router)

I also noticed this diagram for the APs.  2 of these APs are in a cathedral type ceiling going to need a long scissor lift vehicle if we need to physically reset.

Thanks for the help!

Question in the reply above, the picture shows 2 VLANS, if the switch is replaced with a flat switch, will all devices revert to the default vlan 1?

Thanks.

No, the settings are stored in the Meraki cloud, so the new switch will assume the settings that are on the network.
