I'm confused about something I'm new to this, for example I use network switches in my network they support RSTP protocole, So let say every switch have 5 port. Switch base MAC address , aa:bb:xx:yy:zz:00 so port 1 bpdu send aa:bb:xx:yy:zz:01, port 2 aa:bb:xx:yy:zz:02 and port 3 ..etc. When I add new network switch to this network,Should the new device's MAC address be equal to the other device's (base MAC address + port number)? A mean new switch MAC addres start with aa:bb:xx:yy:zz:06 ? How are these MAC address conditions taken into account when producing RSTP devices? How can I find a resource on this?
Should the new device's MAC address be equal to the other device's (base MAC address + port number)?
No, definitely not. The vendor is required to provide unique addresses and ranges to each device. I'm referring to a device's source MAC address, of course.
"Unique" in this case might not be literally globally and eternally unique, but unique enough so that no two devices with the same MAC could ever meet each other.
