ABOUT THE TIGERSWITCH 10/100

Switch Management

This switch includes a built-in management agent that offers a variety of management options, including SNMP, RMON and a Web-based interface. The switch also includes an RS-232 serial port for out-of-band management. A PC may be connected to this port for configuration and monitoring purposes out-of-band via a full-handshaking null-modem cable.

The management agent provides a wide range of advanced performance-enhancing features. Multicast filtering provides support for real-time network applications. Port-based and tagged VLANs, plus support for automatic GVRP VLAN registration provide traffic security and efficient use of network bandwidth. QoS priority queueing ensures the minimum delay for moving real-time multimedia data across the network. Flow control eliminates the loss of packets due to bottlenecks caused by port saturation. And broadcast storm control prevents broadcast traffic storms from engulfing the network.

Some of the switch’s advanced features are described below. For a detailed description, refer to the Management Guide.

Spanning Tree Protocol

The TigerSwitch 10/100 supports IEEE 802.1D Spanning Tree Protocol. This protocol adds a level of fault tolerance by allowing two or more redundant connections to be created between a pair of LAN segments. When there are multiple physical paths between segments, this protocol will choose a single path and disable all others to ensure that only one route exists between any two stations on the network. This prevents the creation of network loops. However, if the chosen path should fail for any reason, an alternate path will be activated to maintain the connection.

The default setting for the Spanning Tree Protocol is “enabled.” This protocol may be configured out-of-band via the serial console
