Insight Managed 8-Port Gigabit (Hi-Power) PoE+ Smart Cloud Switch with NETGEAR FlexPoE Power The following table describes the nonconfigurable Auto-VoIP status information. Table 25. Auto-VoIP status Field Description Auto-VoIP VLAN ID The Auto-VoIP VLAN ID. Maximum Number of Voice Channels Supported The maximum number of voice channels supported. Number of Voice Channels Detected The number of VoIP channels prioritized successfully. 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. Spanning Tree Protocol overview Classic STP provides a single path between end stations, avoiding and eliminating loops. For information on configuring Common STP, see Configure the CST port Settings on page 151. 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. Note: For two bridges to be in the same region, the force version must be 802.1s and their configuration names, digest keys, and revision levels must match. For additional information about regions and their effect on network topology, refer to the IEEE 802.1Q standard. Configure Switching 147 User Manual
