I have connected two switches
sw1 and sw2 using two ports i.e. f0/1 and f0/2
sw1=================sw2
f0/1 mac a1 f0/1 mac a2
f0/2 mac b1 f0/2 mac b2
now
sw1 is root
but when i check the mac address-table on sw1
i learn sw2's port f0/1 and f0/2's mac address
1. i dont know how it learn the mac address of there ports as one of the port is in blocking , not sending any message
2. if i change the native vlan to like say 100 , than 4 mac adress are learned 2 for vlan 1 and 2 for vlan 100 , showing the same mac-address i.e. of sw2's f0/1,f0/2 's interfaces.
sw2 learns only 1 mac address i.e of the f0/1 port of sw1 nothing else.
and if native vlan is changed than again 2 entires of vlan 1 and vlan 100 but same mac-address >
