Maybe I have unusual configuration but look at this: arya:~# ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: lan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master br0 state UP mode DEFAULT group default qlen 1000 link/ether 14:da:e9:ab:a4:e9 brd ff:ff:ff:ff:ff:ff 4: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default link/ether 14:da:e9:ab:a4:e9 brd ff:ff:ff:ff:ff:ff 10: kvm0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master br0 state UNKNOWN mode DEFAULT group default qlen 500 link/ether 4a:f9:f8:e1:5a:7a brd ff:ff:ff:ff:ff:ff MAC address for lan and br0 are the same. lan is physical Ethernet interface and br0 is bridge interface. When I plug USB Ethernet adapter I have the next: arya:~# ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: lan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master br0 state UP mode DEFAULT group default qlen 1000 link/ether 14:da:e9:ab:a4:e9 brd ff:ff:ff:ff:ff:ff 4: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default link/ether 00:60:6e:00:48:1a brd ff:ff:ff:ff:ff:ff 10: kvm0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master br0 state UNKNOWN mode DEFAULT group default qlen 500 link/ether 4a:f9:f8:e1:5a:7a brd ff:ff:ff:ff:ff:ff 16: usb: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master br0 state UP mode DEFAULT group default qlen 1000 link/ether 00:60:6e:00:48:1a brd ff:ff:ff:ff:ff:ff Now, USB Ethernet interface (usb) and bridge (br0) have the same MAC. I know that I made unusual config but anyway I think that the naming interface by using MAC (or part of it) is not good idea. Or I still live in the time when the interfaces have had real (i.e. human readable and easy to remember) names. -- Best regards -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
