5. Select Switching> Auto-VoIP.
6. Select which type of interfaces display onscreen:
• To display physical ports only, click the PORTS link.
• To display LAGs only, click the LAGS link.
• To display both physical ports and LAGs, click the All link.
7. Select one or more interfaces by taking one of the following actions:
• To configure a single interface, select the check box associated with the interface, or
type the interface number in the Go To Interface field and click the Go button.
• To configure multiple interfaces with the same settings, select the check box
associated with each interface.
• To configure all interfaces with the same settings, select the check box in the heading
row.
8. From the Auto-VoIP Mode menu, select one of the following options:

Configure 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 on configuring Common STP, see
Configure CST Port Settings on page 122.
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 the forwarding state). 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 the
forwarding state and the suppression of Topology Change Notification. These features are
represented by the parameters pointtopoint and edgeport. MSTP is compatible with both
RSTP and STP. It behaves in a way that is appropriate for STP and RSTP bridges. An MSTP
bridge can be configured to behave entirely as an RSTP bridge or an STP bridge.
