wwan mac address changes

#1 Post by brcisna »

Hello All,

Debian Bullseye

Setting up a dual / failover wwan setup that is using two identical Sierra Wireless modems.
To circumvent the wwan# from changing from one to the other when making a NetworkManager connection,,I placed entries for each at /etc/systemd/network/10-interface#.link
[Match]
MACAddress=<macaddress>
[Link]
Name=wwan0

When i do this,,reboot, each of the two wwan modules comes up in 'ip a; with a totally different mac address showing.
Each one will show three different mac addresses if i keep making another entry in /etc/systemd/network
I am missing something I'm sure.

Thanks
