I asked this in another forum, but was hoping for some other explanations...
switchport mode trunk
switchport native vlan 80
switchport trunk allowed vlan 50, 80
Can someone provide a line by line explanation of whats being done?
If I understand correctly, the first line lets ALL vlans through this port. The second line lets all untagged traffic that comes from VLAN 80 through. Line three perplexes me, because if we are trunking the port (letting all VLANs through) why explicitly let these two VLANs through when they are already allowed.
