12-6 VLAN Operation and Network Applications
Definition
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.
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.
A protocol used to create a separate Spanning Tree topology for
each VLAN configured in a switch.
A protocol that is compatible with PVSTP and provides
automatic topology changes at 1/10th the speed of PVSTP.
QCSTP is also backwards compatible with IEEE 802.1D.
A protocol used to propagate state information throughout a
switched network.
A GARP application used to dynamically create VLANs across a
switched network.
A GARP application that functions in a similar fashion as GVRP,
except that GMRP registers multicast addresses on ports to
control the flooding of multicast frames.
NOTE: GMRP is not supported in this device.
