hi guys, there's something would like consult with you all...
given the scenario as posted:
assume vlan 10, vlan 20 were set on all 3 switches, and it's identical.
my question is:
1. will this etherchannel be establish?
2. assume SW A is root bridge for vlan 10, 20, running on Rapid-STP, how it elect which port will be in block port? (based on lowest MAC-address?)
