I understand how VLANs work, but am not quite sure what the various settings in my HP switch actually do.
I have an HP 1910 switch, and I'm using the web interface to configure it (personally I'd prefer the CLI, but we have some CLIphobic people involved).
I can set a port to be a tagged or untagged member of a VLAN. I can only set one untagged VLAN on a port, which makes sense. I can also set the port type to Access, Trunk or Hybrid.
What I don't understand is how those two options combine. Why would I set a port as Access, and have it a tagged member of multiple VLANs?
What is the difference between Access, Trunk and Hybrid, and how do they differ in how they handle incoming and outgoing tagged and untagged traffic?
