VLAN Term Definition

1Q Connection (previously referred to as a 1Q Trunk)

A connection between 802.1Q switches that passes only traffic with a VLAN Tag Header inserted in each frame. All VLANs in the port’s Port VLAN List are configured to transmit all frames as tagged frames. The port will drop all incoming frames that do not have a VLAN tag.

1D Connection	This is a reference to a connection from a switch that passes only
	untagged traffic. By default, a port designated to pass only
	untagged frames has all VLANs on its Port VLAN List and is
	configured to transmit all frames as untagged frames.
		NOTE: You cannot configure an interface to receive
		only untagged frames.
Per VLAN Spanning Tree	A protocol used to create a separate Spanning Tree topology for
Protocol (PVSTP)	each VLAN configured in a switch.
Quick Convergence STP	A protocol that is compatible with PVSTP and provides
(QCSTP)	automatic topology changes at 1/10th the speed of PVSTP.
	QCSTP is also backwards compatible with IEEE 802.1D.
Generic Attribute	A protocol used to propagate state information throughout a
Registration Protocol	switched network.
(GARP)
GARP VLAN	A GARP application used to dynamically create VLANs across a
Registration Protocol	switched network.
(GVRP)
GARP Multicast	A GARP application that functions in a similar fashion as GVRP,
Registration Protocol	except that GMRP registers multicast addresses on ports to
(GMRP)	control the flooding of multicast frames.
		NOTE: GMRP is not supported in this device.
