Setting MAC on bridge

Hi all.
I was trying to get this by reading the wiki, but couldn't get anything useful.

Anyway, what i want to do is (as the topics hints about) to set the mac address of a bridge interface. And of course I would like to accomplish this by using the config files.

Best Regards.

Re: Setting MAC on bridge

you can use

ifconfig [interface] hw ether

on bridges.
put that in rc.local or if this would be to late in the init process, put it directly
in bridge_up() in rc.d/network

/etc/rc.conf

INTERFACES=(eth0 br0)

/etc/conf.d/bridges

mac_br0="AA:BB:CC:DD:EE:FF"
BRIDGE_INTERFACES=(br0)

/etc/rc.d/network

#in bridge_up() after "brctl addbr"
eval brmac="\$mac_${br}"
/sbin/ifconfig $br hw ether $brmac || error=1

Re: Setting MAC on bridge

Some feedback.
I got this working, but i needed to put the ifconfig $br hw.. line after each of the interfaces hade been added, otherwise the MAC got changed when the if's got added.

So thanks alot fresch
