[. . . ] This switch supports static, port-based VLANs. 5-30 SM-10004-02 Web-Based Management Interface 700 Series Managed Switch User's Guide for Software v2. 1 Advanced> VLAN> Primary VLAN Figure 5-32: Primary VLAN A `U' or `T' will be displayed for each port assigned to the VLAN, where `U' stands for untagged and `T' for tagged. If a port is an untagged member of a VLAN, the VLAN tag will be striped from the frame before it is sent out that port. If the port is a tagged member of a VLAN, the VLAN tag will stay in the frame when it is sent. A blank indicates that the port is not a member of the particular VLAN, and will not get any traffic for that VLAN. The VLAN tagging option is a standard set by the IEEE to facilitate the spanning of VLANs across multiple switches (Reference: Appendix B and IEEE Std 802. 1Q-1998 Virtual Bridged Local Area Networks). From this menu, you can create a new VLAN, add new ports to an existing VLAN, remove ports from an existing VLAN or, delete a VLAN. Create a new VLAN Group Under the `Show VLAN' drop down menu, select `Add a new VLAN'. Enter the VLAN Id and name in the provided fields. Delete a VLAN Group Check the Remove VLAN box for the VLAN you want to remove. Web-Based Management Interface SM-10004-02 5-31 700 Series Managed Switch User's Guide for Software v2. 1 Click Apply. Add a port to a VLAN Group Under the `Show VLAN' drop down menu, select the VLAN you want to edit. Click the box below the port number on the line of the VLAN so that a `T' (tagged) or `U' (untagged) appears. Remove a port from a VLAN Group Click the box again until a blank box appears. This will remove VLAN membership from the port. Advanced> VLAN> VLAN Port Figure 5-33: VLAN Port Settings All untagged packets entering the switch will by default be tagged with the ID specified by the port's PVID. This screen allows you to specify the PVID for each port. The number next to each port indicates which PVID is set for each port. Following industry standards, PVID 1 is the default PVID. 5-32 SM-10004-02 Web-Based Management Interface 700 Series Managed Switch User's Guide for Software v2. 1 Advanced> Spanning Tree This switch is compliant with IEEE802. 1D Spanning Tree Protocol (STP). STP ensures that only one path at a time is active between any two network nodes. There maybe more than one physical path between any two nodes, forming a loop, either created for redundancy or by accident. STP ensures only one physical path is active and the others are blocked. If a loop is created for redundancy, STP will monitor the two paths and activate the stand-by path if the primary path fails. If a loop was created inadvertently, STP will disable one of the two paths. [. . . ] A protocol allowing a computer using TCP/IP to connect directly to the Internet. Glossary SM-10004-02 7 700 Series Managed Switch User's Guide for Software v2. 1 Port monitoring The ability to monitor the traffic passing through a port on a device to analyze network characteristics and perform troubleshooting. Port speed The speed that a port on a device uses to communicate with another device or the network. Port trunking The ability to combine multiple ports on a device to create a single, high-bandwidth connection. Protocol A set of rules for communication between devices on a network. Quality of Service A term to describe delay, throughput, bandwidth, and other factors that measure the service quality provided to a user. RADIUS Short for Remote Authentication Dial-In User Service, RADIUS is an authentication system. Using RADIUS, you must enter your user name and password before gaining access to a network. This information is passed to a RADIUS server, which checks that the information is correct, and then authorizes access. Though not an official standard, the RADIUS specification is maintained by a working group of the IETF. RIP A protocol in which routers periodically exchange information with one another so that they can determine minimum distance paths between sources and destinations. router A device that forwards data between networks.
