I'm trying to create a trunk across a link that my isp has given to me. I have a 3550 at both ends and I need to move across a couple of vlans.
I have tried this config and the trunk comes up, but I cannot transfer any ip information across it.
This is configured on both ends:
switchport access vlan 509
switchport trunk encapsulation dot1q
switchport trunk native vlan 509
switchport trunk allowed vlan 509
switchport mode trunk
Do I need to create a tunnel or something first?
