WAN Switch

[piasterloo]

Folks ,we are building a new network and it involves two MS130 8 port WAN break switches , I would like to know if there is any advantage in keeping those switches into a completely different network

Thank you

Yes, it would give you better/more consistant reporting.

Check out the slide deck in this topic https://community.meraki.com/t5/Security-SD-WAN/How-to-turn-MS120-into-WAN-breakout-for-2-ISPs-and-2...

hi @ww where does it show a flaw in reporting ,sorry i was not able to find it !

What happens is that all lan side network traffic passes through several devices and have some correlation so its not displayed several times in your dashboard. 

But for example: when you are using switches on lan and wan side in the same dashboard network you will see a LANclient-to-wan traffic flow as a private IP but also as wan IP(nat). 

[piasterloo]

But we have separate dashboard network for WAN and LAN (LAN includes the WAN switches as well) does that makes any difference in reporting  ?

No that is exactly how you should implement it

Hi @piasterloo,
I +1 @ww here, having these switches in a separate network will help not to break reporting 😀

How does that help or differ in reporting when we keep them on different network ,any example you can provide regarding the reporting is appreciated .thx

Traffic flows through internal switching and gets reported, but also flows through the wan side. Both from different MAC addresses, so you will get double reporting on single flow of traffic. Once from the client itself and once from the MX/router wan side.

The reporting on users/devices in your network will also no longer be correct, as the router/MX will be the top one always
