Both vendors use different terminology in regards to VLANs.
This can be confusing for the Cisco expert.
It seems that Cisco is the odd one out in this regard. Naughty Cisco.
I’ve been doing some reading and I think I can make it simple.
A trunk port on a Cisco device is one that sends out encapsulated tagged packets. ie. They have a VLAN tag.
So on a Dlink device, you make a ‘Cisco trunk port’ by enabling tagging on that port for the specific VLANs.
An untagged port on a Dlink is like a ‘switchport mode access’ port on a Cisco – it has no vlan tag – and the port is forced to be on the specified VLAN.
Information that would have been useful earlier today, but hey. What can you do?
