[. . . ] Toggle the check box for each port to change its membership and tag setting: · · · An empty check box indicates that the port is not a member of this VLAN. Click Apply. Figure 4-12 Note: Every port has an initial default VID of 1 (PVID = 1). Whether a port has this VID or has been made a member of another default VID, you cannot remove any port from its prior default VLAN until you have reassigned its PVID to its new value. Use the PVID Setting menu option of VLAN Management to change its PVID before attempting to remove it from its prior default membership. The PVID Configuration table contains parameters for assigning Port VLAN ID (PVID) values to interfaces. If you want to change the port's default PVID, you must first create a VLAN group that includes the port. In the PVID field, enter a valid VLAN ID. Configuring the Switch v1. 0, October 2007 4-9 Smart Switch Software User Manual GS748T 3. Click Apply. Figure 4-13 Configuring Port-Based VLANs Unlike 802. 1Q based VLAN, an ingress packet with an 802. 1Q tag is ignored and preserved. Select Switching > VLAN > VLAN Configuration from the main menu. In the VLAN Name field, assign a name to help you to identify this VLAN. Click Add. 4-10 v1. 0, October 2007 Configuring the Switch Smart Switch Software User Manual GS748T To modify a Port-Based VLAN membership: 1. From the VLAN Identifier pull-down menu, select the VLAN that you want to modify. To delete a VLAN: Select the VLAN you want to remove and click Delete. all port associations are separated from the VLAN and it is removed. Selecting a Management VLAN The Management VLAN allows you to establish an IP connection to the switch from a PC connected to a port in that VLAN. This increases security by allowing only PCs in the management VLAN to configure the switch. In the Management VLAN ID field, enter the ID of the VLAN that you want to use for managing the switch. A zero value means that any PC in any of the VLANs can establish an IP connection to the switch. Click Apply to save your settings. Enabling Spanning Tree Protocol To achieve reliability in a network, some path redundancy must be provided. However, multiple paths between network nodes can cause loops to exist and result in switching confusion and duplication of traffic. Spanning Tree Protocol (defined by IEE 802. 1D) controls the duplicate paths by accounting for statistical weights in the available paths. It blocks the least efficient alternate paths and causes traffic only to be carried over the optimal paths between nodes. The GS748T switch supports Rapid Spanning Tree Protocol (defined by IEEE 802. 1w), which is an improvement (over the 802. 1D STP) that shortens connection latency between nodes. [. . . ] To further enhance the operation, the cabling standards have been amended. The latest standard is Category 5e, which defines a higher level of link performance than is available with Category 5 cable. If installing new cable, we recommend using Category 5e cable, since it costs about the same as Category 5 cable. If using the existing cable, be sure to have the cable plant tested by a professional who can verify that it meets or exceeds either ANSI/EIA/TIA-568-A:1995 or ISO/ IEC 11801:1995 Category 5 specifications.
