L2 Features > Voice VLAN > Voice VLAN Device
The Voice VLAN Device page is used to show voice devices that are connected to the Switch. The Start
Time is the time when the device was detected on the port and the Status displays the voice VLAN status of
the port.

The Switch implements three versions of the Spanning Tree Protocol: Rapid Spanning Tree Protocol (RSTP)
as defined by IEEE 802.1w, a version compatible with the IEEE 802.1D STP and Multiple Spanning Tree
Protocol (MSTP), as defined by IEEE802.1. RSTP can operate with legacy equipment implementing IEEE
802.1D, however the advantages of using RSTP will be lost.
The Rapid Spanning Tree Protocol (RSTP) evolved from the 802.1D STP standard and was developed in
order to overcome some of the limitations of STP that impede the function of some recent switching
innovations. The basic function and much of the terminology is the same and most of the settings configured
for STP are also used for RSTP. This section introduces some new Spanning Tree concepts and illustrates
the main differences between the two protocols.
The IEEE 802.1 Multiple Spanning Tree (MSTP) provides various load balancing techniques by allowing
multiple VLANs to be mapped to a single spanning tree instance, providing multiple pathways across the
network. For example, while port A is blocked in one STP instance, the same port can be placed in the
Forwarding state in another STP instance.
