Where is the MAC address of a bridge interface stored in Debian and what is the method to modify it?

edit

The MAC address of a bridge interface in Debian is stored in the /sys/class/net/bridgename/address file, where "bridgename" is the name of your bridge interface.

To modify the MAC address of a bridge interface, you can use the ip command with the link option. For example, if you want to change the MAC address of the br0 interface to 01:23:45:67:89:ab, you would use the following command:

sudo ip link set dev br0 address 01:23:45:67:89:ab

Note: You need to be root or have sudo privileges to modify the MAC address of a network interface in Debian.
