Spanning Tree: Port Settings For the Port Settings options, you can specify Spanning Tree port priority, cost, and Fastlink parameters for each port. 5-34 SM-10004-02 Web-Based Management Interface 700 Series Managed Switch User's Guide for Software v2. 1 Table 5-1. Prty (Priority) Cost STP Port Setting Parameters PARAMETERS RANGE 0-255 1-65535 DESCRIPTION STP uses this to determine which path (which port) to use for forwarding. The switch uses this to determine which port is the forwarding port when the priority is equal. All other factors equal, the path with the lowest cost to the root bridge will be the active path. The default path cost is the maximum speed for the port. Fastlink Enabled or Disabled When a Fastlink enabled port running standard STP is connected, it will go through the STP negotiation (listening -> learning -> forwarding or blocking) before it will be fully available. Fastlink in STP mode. If a client is trying to access a server through the switch running the STP negotiation, it will not be able to connect to it immediately. Fastlink mode solves this problem by setting the port to direct forwarding mode, thus allowing any server access request to be forwarded. Fastlink mode can cause temporary loops in your network, but STP will find and eliminate them. ports connected to PCs or servers, and not on uplink ports to other switches. Advanced> MAC There are two advanced MAC setup configurations options: · · Aging Time Static Address Web-Based Management Interface SM-10004-02 5-35 700 Series Managed Switch User's Guide for Software v2. 1 Advanced> MAC> Address Aging Figure 5-36: MAC > Address Aging Aging Time is a variable that must be configured. Its purpose is to determine the amount of time an entry is held in the forwarding tables while no activity occurs from that address. Entries should be removed to update the table for MAC addresses that have moved or are turned off. · · · The industry standard default value is 300 seconds (5 minutes). The administrator may change this value to any value between 10 and 1, 000, 000 seconds. After changing the value, click `Apply' Advanced> MAC> Static Addresses Figure 5-37: MAC > Static Addresses 5-36 SM-10004-02 Web-Based Management Interface 700 Series Managed Switch User's Guide for Software v2. 1 Any system, whose MAC address and the port number are listed in this screen, will not be purged from the system's forwarding table by the aging process. 1. 6. Add a new entry Enter the MAC address and port in the appropriate boxes Click Add Remove an exist entry Highlight that entry in the table, by clicking on the MAC address Choose Remove Advanced> Multimedia Support Use the advanced multimedia support menu to manage high-bandwidth network traffic by enabling/disabling Internet Group Multicast Protocol (IGMP) traffic and configuring static multicast groups. Advanced> Multimedia Support>Enable/Disable IGMP Figure 5-38: Multimedia Support > Enable/Disable IGMP In networks where multimedia applications generate multicast traffic, IGMP can greatly reduce unnecessary bandwidth usage by limiting traffic forwarding that is otherwise broadcast to the whole network. Enabling IGMP will allow individual ports to detect IGMP queries, report packets, and manage IP multicast traffic through the switch. Web-Based Management Interface SM-10004-02 5-37 700 Series Managed Switch User's Guide for Software v2. 1 · · Enable. The system will detect IGMP queries, report packets, and manage IP multicast traffic through the switch Disable. The switch will forward traffic and disregard any IGMP requests. Advanced>Multimedia Support> Static Multicast Groups Figure 5-39: Multimedia Support > Static Multicast Groups You can use this menu t configure permanently reachable multicast groups. The Static Multicast Administration menu lets you create individual groups by entering a MAC address of your static multicast group. Click on the ports to add them to the multicast group. Advanced> SNMP You can manage this switch using the Simple Network Management Protocol (SNMP) from a network management station. To do so, you must configure your switch to participate in the SNMP community and you must add the SNMP host agent to the host table. [. . . ] For example, a 28-bit mask starting from the MSB can be shown as 255. 255. 255. 192 or as /28 appended to the IP address. Network Address Translation A technique by which several hosts share a single IP address for access to the Internet. packet A block of information sent over a network. A packet typically contains a source and destination network address, some protocol and length information, a block of data, and a checksum. Point-to-Point Protocol PPP. 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. [. . . ]
