Where I ran into the terminology issue and it caused a lot of headaches was
with Cisco and H-P ethernet switches.
What Cisco calls "Fast Etherchannel" H-P calls "Trunking".
What Cisco calls "Trunking" H-P calls "Multiple VLAN Tagged"
Arrrgggggh!
Me: So set up the port towards the router as a trunk.
HP guy: Trunked with what?
Me: With the router.
HP guy: No, trunked with what else?
Me: With the three VLANs on the switch.
HP guy: You've got to trunk it with another port on the router if you
want it to be a trunk.
Me: No, I've only got one trunk port on the router.
HP guy: You can't use it as a trunk if you've only got one port!
Me: Of course you can! Your switch will do dot1Q, right?
HP guy: Sure it will.
Me: Then give me a dot1Q trunk with your VLANs per the map we made.
HP guy: That doesn't make any sense!
Me: Where are the docs on that switch, let's figure this out...
A couple of PDF files later, we were talking to each other.
