Tagged means the port can send/receive traffic for multiple VLANs. Before sending, the ethernet frames are "tagged" with the VLAN number so the receiving switch will know what VLAN a particular frame is a member of.

Untagged means the port can only send/receive traffic for one specific VLAN.

Forbid is used in a GVRP environment where VLANs are dynamically added. It prevents a VLAN from being added to a port.  If you're not doing GVRP, then forbid mode is unnecessary.

That depends on which vendor's terminology you're using. :-)

In HP parlance, a "trunk" is two or more links that are aggregated together (what Cisco calls etherchannel).

HP referrers to a link carrying multiple VLANs as a "tagged" or "tagging" port (what Cisco calls a trunk).

on my HP series I 4208 I have the same, tagged and untagged....
I need to make a trunk of some ports.
With Cisco this is easy with the trunkport config
