To configure the Auto-VoIP parameters, use the Auto-VoIP configuration screen. The 
Interface column specifies all the configurable Auto-VoIP interfaces. The Traffic Class 
displays the traffic class on which the received VoIP frames are marked.
To enable Auto-VoIP:
1. 
Select Switching
> Auto-VoIP
1. 
To configure Auto-VoIP interface settings for a physical port or a LAG port, click PORT
LAGS, or All.
Or:
2. 
Enter the interface name in the Go To Interface field and click Go
The entry corresponding to the specified port is selected.
3. 
Select Enable or Disable from the Auto-VoIP Mode drop-down list, as the Auto-VoIP 
administrative mode for the interface. 
Traffic Class is pre configured and cannot be changed.
4. 
Click Apply to send the updated configuration to the switch.
Spanning Tree Protocol
The Spanning Tree Protocol (STP) provides a tree topology for any arrangement of bridges. 
STP also provides one path between end stations on a network, eliminating loops. Spanning 
tree versions supported include Common STP, Multiple STP, and Rapid STP.
Classic STP provides a single path between end stations, avoiding and eliminating loops. For 
information about configuring Common STP, see 
62.
Multiple Spanning Tree Protocol (MSTP) supports multiple instances of spanning tree to 
efficiently channel VLAN traffic over different interfaces. Each instance of the spanning tree 
behaves in the manner specified in IEEE 802.1w, Rapid Spanning Tree (RSTP), with slight 
modifications in the working but not the end effect (chief among the effects, is the rapid 
transitioning of the port to ‘forwarding’). The difference between the RSTP and the traditional 
STP (IEEE 802.1D) is the ability to configure and recognize full-duplex connectivity and ports 
that are connected to end stations, resulting in rapid transitioning of the port to forwarding 
state and the suppression of Topology Change Notification. These features are represented 
by the parameters point-to-point and edgeport. MSTP is compatible with both RSTP and 
STP, and can be configured to operate entirely as an RSTP bridge or an STP bridge.
Note:
For two bridges to be in the same region, the force version should be 
802.1s (MSTP), and their configuration name, digest key, and revision 
level should match. For more information about regions and their 
effect on network topology, refer to the IEEE 
802.1Q
 standard.
