ProSAFE 10-Gigabit Smart Managed Switch XS728T and XS748T User Manual
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.
From the Switching > STP > Advanced menu, you can access pages that are described in
the following sections:
• Configure STP Settings on page 118
• Configure CST Settings on page 120
• Configure CST Port Settings on page 122
• View the CST Port Status on page 124
• View Rapid STP Information on page 126
• Manage MST Settings on page 127
• Configure MST Port Settings on page 130
• View STP Statistics on page 132
Configure STP Settings
The STP Configuration page contains fields for enabling STP on the switch.
To configure STP settings:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Change the Default IP Address of the
Switch on page 10.
