[Experience] Two Mxs with the same Mac Address and Serial Number
I have been deploying around 120 Meraki Branches and the last week I got a serious issue with was too hard to troubleshoot.
I was having issues registering the mx bc I did not saw it online in the dashboard. I tried to see if it had the VPN Tunnels up and I saw that another branch wich is not installed yet was taking up their tunnels.
I blink the leds in the MX in the dashboard with another serial number and I saw it blinking.
Then I realized that I had those switches with certain conflict so I performed a lab with them and now I`m seeing in the switch that they have the same mac address
Re: [Experience] Two Mxs with the same Mac Address and Serial Number
The only time I've ever seen two MX's with the same MAC is when they are configured together in Warm Spare. In that scenario the spare unit will use the MAC of the Primary (on the LAN only) anytime it transitions to Master.
