[. . . ] Select a port number from the left selection list and click Add to add the port to the VLAN. Select a port number from the right selection list and click Remove to remove the port from the VLAN. Ports in the same VLAN must be in the same trunk group. 9. 5 Tag-Based VLAN Configuration Follow the steps below to configure VLANs on the switch. In the Switch Configuration screen, select either 802. 1Q with GVRP or 802. 1Q without GVRP from the VLAN Operation Mode drop-down list box. Click Administrator and then VLAN Configuration to display the basic VLAN screen as shown next. Figure 9-4 VLAN Setup ­ 802. 1Q with/without GVRP VLAN Information 9-4 VLAN Dimension ES-2008 Ethernet Switch Step 3. A setup screen displays. Figure 9-5 Tag-Based VLAN: 802. 1 Q VLAN Basic Setup Follow the instructions in Table 9-2 to set the fields in this screen. Click Next to continue. Figure 9-6 VLAN Setup: 802. 1Q VLAN Port Tagging Follow the instructions in the next table to set the fields in this screen. VLAN 9-5 Dimension ES-2008 Ethernet Switch Table 9-3 VLAN Setup: 802. 1Q VLAN Port Tagging FIELD VLAN Name VLAN ID Port No Setting DESCRIPTION This read-only field displays the name of the VLAN. This read-only field displays the identification number of the VLAN group. Select Tag from the drop-down list box to add VLAN ID to the outgoing frames on this port. Otherwise select Untag. 9. 5. 1 Configure Port Settings Click Administration, VLAN Configuration and then Port VLAN ID to display the screen as shown next. Figure 9-7 Tag-Based VLAN: Port VLAN ID The following table describes the fields in this screen. Table 9-4 Tag-Based VLAN: Port VLAN ID FIELD Port VLAN ID DESCRIPTION This read-only field displays the port number on the switch. Enter the VLAN ID (between 2 and 4094) that will be assigned to untagged traffic on a given port. For example, if the default VLAN ID of port 5 is 100, all untagged packets on port 5 will belong to VLAN 100. 9-6 VLAN Dimension ES-2008 Ethernet Switch The default VLAN ID for all ports is 1. This feature is useful for accommodating devices that you want to participate in the VLAN but that don't support tagging. Ingress Filtering Acceptable Frame Type Select Enable from the drop-down list box to forward a frame whose VID is the same as the VID of the port. Select Disable to forward all frames, regardless of the port's VID. Select All from the drop-down list box to accept all untagged or tagged frames. Select Tag Only to drop all untagged frames. VLAN 9-7 Dimension ES-2008 Ethernet Switch Chapter 10 Spanning Tree Protocol This chapter describes the basics and configuration of STP. 10. 1 Introduction Spanning Tree Protocol) is a standardized method (IEEE 802. 1D) that eliminates loops in a network by disabling some ports and allowing other ports to forward traffic based on the parameters you configured. STP ensures that there is only one path between a specific source and destination so packets will not travel in loops. STP provides path redundancy while preventing undesirable loops in the network. STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a device to interact with other STP-aware devices in your network to ensure that only one path exists between any two stations on the network. The root bridge is the base of the spanning tree; it is the bridge with the lowest identifier value (MAC address).
