SMC’s TigerSwitch™ 10/100 is an intelligent Fast Ethernet 10BASE-T/100BASE-TX ports and two 10/100/1000BASE-T combo ports that operate in combination with 2 Small Form Factor Pluggable (SFP) transceiver slots. This switch can easily tame your network with full support for Spanning Tree Protocol, Multicast Switching, Virtual LANs, and Layer 2/3/4 CoS services.

Switch Architecture

The TigerSwitch 10/100 employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

Switching Method

The switch uses store-and-forward switching to ensure maximum data integrity. With store-and-forward switching, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.

Management Options

This switch contains a comprehensive array of LEDs for “at-a- glance” monitoring of network and port status. It also includes a built-in network management agent that allows the switch to be managed in-band using SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web browser, or remotely via Telnet. The switch provides an RS-232 serial port (DB-9 connector) on the front panel for out-of-band management. A PC may be connected to this port null-modem cable. (See Appendix B for wiring options.)

for configuration and monitoring out-of band via a

This switch provides a wide range of advanced performance-enhancing features. Port-based and tagged VLANs, plus support for automatic GVRP VLAN registration and IGMP multicast filtering 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. Broadcast storm control prevents broadcast traffic storms from engulfing the network. Some of this switch’s advanced features are described below. For a detailed description, refer to the Management Guide.

VERVIEW

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, the 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 port, or in-band via the Web interface, Telnet, or SNMP network management software.

VLANs

The TigerSwitch 10/100 supports up to 255 VLANs. A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. By segmenting your network into VLANs, you can:

• Eliminate broadcast storms which severely degrade performance in a

flat network.

• Simplify network management for node changes/moves by remotely

configuring VLAN membership for any port, rather than having to manually change the node’s IP address.

• Provide data security by restricting all traffic to the originating VLAN,

except where a connection is explicitly defined via the switch’s routing service.

BOUT THE TIGERSWITCH

Multicast Switching

Specific multicast traffic can be assigned to its own VLAN to ensure that it does not interfere with normal network traffic and to guarantee real-time delivery by setting the required priority level for the designated VLAN. The switch uses IGMP Snooping and IGMP to manage multicast group registration.

Traffic Priority

This switch provides Class of Service (CoS) by prioritizing each packet based on the required level of service, using four distinct queues with Weighted Round Robin queuing for each port. It uses IEEE 802.1p and

802.1Q tags to prioritize incoming traffic based on input from the end-station application. Also, the switch provides Layer 3/4 priority mapping of IP Precedence/DSCP values or IP TCP/UDP port numbers to the IEEE 802.1p priority tag of each frame. These functions can be used to provide independent priorities for different types of traffic, such as delay-sensitive data and best-effort data.

Description of Hardware

10BASE-T/100BASE-TX Ports

These are dual-speed RJ-45 ports. Because all ports on this switch support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. (See“100BASE-TX/10BASE-T Pin Assignments” on page B-3.)

Each of these ports support auto-negotiation, so the optimum transmission mode (half or full duplex), and data rate (10 or 100 Mbps) can be selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually.

Each port also supports IEEE 802.3x auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated.

1000BASE-T/SFP Ports

These are combo Gigabit RJ-45 ports with shared Small Form Factor Pluggable (SFP) transceiver slots. If an SFP transceiver (purchased separately) is installed in a slot and has a valid link on the port, the associated RJ-45 port is disabled.

The 1000BASE-T RJ-45 ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. (See“1000BASE-T Pin Assignments” on page B-4.)

Optional Redundant Power Unit

SMC provides an optional Redundant Power Unit (RPU), SMCRPS600W, that can supply power to the switch in the event of failure of the internal power supply.

Power Supply Receptacles

There are two power receptacles on the rear panel of the switch. The standard power receptacle is for the AC power cord. The receptacle labeled “DC Input” is for the optional Redundant Power Unit (RPU).
