How to ethernet managable network switch manage the dynamic table entries although receive "port base MAC address frame" like RSTP,STP protocole ?
I know the dynamic mac table save the entries with received Frame's "Source Address". But like a BPDU frames have different structure in Source Address bytes. How to ethernet switches seperate it's BPDU or ARP-ICMP etc. packet and saved it's dynamic table ?
Static or Multicast table work with DA but the dynamic table looks just Source Address. How to decide it saved or not ?
For example type of below topology
PC I Switch 1 (03:0b:aa:00:00:01) I Switch 2 (03:0b:aa:00:00:02) I Switch 3 (03:0b:aa:00:00:03)
(I: refer to ethernet cable between them)
How to decide which one is save on Switch2's Dynamic Mac tables;
received BPDU packets from Switch1's port 1 with Source address is ((03:0b:aa:00:00:01) + 01( port Info))
or Switch 3's Base MAC address ? (03:0b:aa:00:00:01)
It is very technical question, but I coulndt find anywhere for answer ?
