GS716Tv2 and GS724Tv3 Software Administration Manual Table 3-9. Port VLAN ID Configuration Fields (continued) Field Ingress Filtering Port Priority Description Specify how you want the port to handle tagged frames: • Enable: A tagged frame will be discarded if this port is not a member of the VLAN identified by the VLAN ID in the tag. In an untagged frame, the VLAN is the Port VLAN ID specified for the port that received this frame. • Disable: All frames are forwarded in accordance with the IEEE 802.1Q VLAN standard. The factory default is disable. Specify the default 802.1p priority assigned to untagged packets arriving at the port. Possible values are 0-7. 2. Click Cancel to cancel the configuration on the screen and reset the data on the screen to the latest value of the switch. 3. If you make any changes to this page, click Apply to send the updated configuration to the switch. Configuration changes take place immediately. Configuring 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 "CST Port Configuration" on page 3-21. 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 which 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 'pointtopoint' and 'edgeport'. MSTP is compatible to both RSTP and STP. It behaves appropriately to STP and RSTP bridges. A MSTP bridge can be configured to behave entirely as a RSTP bridge or a STP bridge. 3-16 v1.0, July 2009 Configuring Switching Information
