Getting to Know the Switch

Link/Act Green. Lights to indicate that the switch is successfully connect-

ing to the network. Blinks to indicate the switch is actively receiving or sending the data over the port.

10/100 Green. Lights to indicate that the port is operating at 100 Mbps.

Off to indicate that he port is operating at 10 Mbps while the switch is still working.

FDX/COL Amber. Lights to indicate that the port is operating in full-

duplex mode. Blinks to indicate that the connection is experiencing collisions.

Fan Red. Lights to indicate that the fans are not active.

TEMP Red. Lights to indicate that the switch exceeds its operational

temperature.

Power Green. Lights to indicate that the switch has power.

The Switch is equipped with twenty-four auto-sensing RJ-45 ports. These RJ45 ports support network speeds of either 10Mbps or 100Mbps, and can operate in half and full-duplex modes. Auto-sensing technology enables each port to automatically detect the speed of the device connected to it (10Mbps or 100Mbps), and adjust its speed and duplex accordingly.

To connect a device to a port, you will need to use a network cable. You will need to use Category 5 (or better) cable. For more information on twistedpair cabling, refer to the Twisted-Pair Cabling section.

The Switch is equipped with two expansion ports that provide for the installation of one or two expansion modules. These ports provide links to highspeed network segments or individual workstations at speeds of up to 1000Mbps (Gigabit Ethernet).

To establish a Gigabit Ethernet connection, you will need to install an SX or TX Gigabit expansion module and use Category 5e cabling or fiber optic cabling. for more information on fiber optic cabling, refer to the Fiber Optic Cabling section.

The Switch is equipped with a serial port labeled CONSOLE (located on the front of the switch) that allows you to connect to a computer’s serial port (for configuration purposes) using the provided serial cable.

Installing the Switch

Fast Ethernet Considerations

If you will be using the Switch for Fast Ethernet (100Mbps) applications, you must observe the following guidelines:

Full-Duplex Considerations

As previously mentioned, the Switch provides full-duplex support for its RJ45 ports. Full-duplex operation allows data to be sent and received simultaneously, doubling a port’s potential data throughput.

If you will be using the Switch in full-duplex mode, the maximum cable length using Category 5 cable is 328 feet (100 meters).

Positioning the Switch

Before you choose a location for the Switch, observe the following guidelines:

• Make sure that the switch is accessible and that the cables can be connect-

ed easily.

• Keep cabling away from sources of electrical noise, power lines, and fluo-

rescent lighting fixtures.

• Position the Switch away from water and moisture sources.

• To ensure adequate air flow around the Switch, be sure to provide a mini-

mum clearance of two inches (50 mm).

• Do not stack free-standing Switches more than four units high.

If you need to reset the Switch, remove the power cord from the back of the Switch and then reconnect it.

When you power-on the switch, it performs a Power-On Self Test (POST). During the POST, the Switch’s CPU:

• Performs a series of diagnostic procedures to make sure the basic system is functioning with integrity.

• Decompresses the main switching software run-time image from the flash ROM into DRAM area.

• Begins executing the main switching software. During the POST process if the Esc key is pressed, a COMMAND LINE prompt appears.

Download Runtime This option downloads the runtime system image to Software from the Switch through the Switch's Console port. Before Console Port you select this option, make sure:

• A host system is running a terminal emulation program that supports the Kermit f ile transfer protocol.

• The host system's hard drive has the required binary f ile that will be downloaded to the switch.

Configure the System This option lets you modify any conf igurable parame-

ter in the switch's flash ROM before the switch system boots.

Run Manufacturing This option downloads the manufacturer's diagnos Diagnostics tics. This option has the same download requirements

as the runtime software applied. When the file transfer is completed, the target system jumps to the entry point of the diagnostic program and starts executing the diagnostic code. The Main Menu of the diagnostic program appears, where you can initiate tests or obtain system information. Note that user intervention is not required when a test runs, unless an error occurs. If an error occurs during testing, you are given the choice of continuing the diagnostics or skipping the error.

VLAN & PVID PERSPECTIVE

This section describes the default VLAN and how to obtain a VLAN perspective.

Default VLAN

The IEEE 802.1Q standard defines VLAN ID #1 as the default VLAN. The default VLAN includes all the ports as the factory default. The default VLAN’s egress r ule restricts the por ts to be all untagged, so it can, by default, be easily used as a simple 802.1D bridging domain. The default VLAN’s domain shrinks as untagged ports are def ined in other VLANs.

MIB-2 defines a set of manageable objects in various layers of the TCP/IP protocol suites. MIB-2 covers all manageable objects from layer 1 to layer 4 and, as a result, is the major SNMP MIB supported by all vendors in the networking industry. The Switch supports a complete implementation of SNMP Agent and MIB-2.

RMON MIB (RFC 1757) and Bridge MIB (RFC 1493)

The Switch provides hardware-based RMON counters in the switch chipset. The switch manager CPU polls these counters periodically to collect the statistics in a format that complies with the RMON MIB def inition.

RMON GROUPS SUPPORTED

The Switch supports the following RMON MIB groups defined in RFC1757:

• RMON Statistics Group maintains utilization and error statistics for the switch port being monitored.

• RMON History Group gathers and stores periodic statistical samples from the previous Statistics Group.

• RMON Alarm Group allows a network administrator to define alar m thresholds for any MIB variable. An alarm can be associated with Low Threshold, High Threshold, or both. A trigger can trigger an alarm when the value of a specific MIB variable exceeds a threshold, falls below a threshold, or exceeds or falls below a threshold.

• RMON Event Group allows a network administrator to def ine actions based on alarms. SNMP Traps are generated when RMON Alarms are triggered. The action taken in the Network Management Station depends on the specific network management application.

SNMP and RMON Management

This section describes the Switch’s Simple Network Management Protocol (SNMP) and Remote Monitoring (RMON) capabilities.

RMON is an abbreviation for the Remote Monitoring MIB (Management Information Base). RMON is a system def ined by the Internet Engineering Task Force (IETF) document RFC 1757, which defines how networks can be monitored remotely. RMONs typically consist of two components: an RMON probe and a management workstation:

• The RMON probe is an intelligent device or software agent that continually collects statistics about a LAN segment or VLAN. The RMON probe transfers the collected data to a management workstation on request or when a pre-defined threshold is reached.

• The management workstation collects the statistics that the RMON probe gathers The workstation can reside on the same network as the probe, or it can have an in-band or out-of-band connection to the probe.

The Switch provides RMON capabilities that allow network administrators to set parameters and view statistical counters defined in MIB-II, Bridge MIB, and RMON MIB. RMON activities are performed at a Network Management Station running an SNMP network management application with graphical user interface.

SNMP Agent and MIB-2 (RFC1213)

The SNMP Agent running on the switch manager CPU is responsible for:

• Retrieving MIB counters from various layers of software modules according to the SNMP GET/GET NEXT frame messages.

• Setting MIB variables according to the SNMP SET frame message.

• Generating an SNMP TRAP frame message to the Network Management

Station if the threshold of a certain MIB counter is reached or if other trap conditions (see next page) are met:

Appendix

As the demand for desktop video, multimedia development, imaging, and other speed-intensive applications continues to rise, the need for high performance, fault tolerant LAN technology will become more critical.

Standard Ethernet, which has been the most popular networking technology to date with a maximum data throughput of 10Mbps (Megabits per second), is becoming insufficient to handle the latest video, multimedia, and other speed-intensive client/server LAN applications.

Among the solutions to the problem of network speed, Fast Ethernet has emerged as the most viable and economical. Capable of sending and receiving data at 100Mbps, it is more than fast enough to handle even the most demanding video and other real-time applications.

Although there are a number of different competing Fast Ethernet implementations, 100BaseTX is by far the most popular. Operating on two pairs of Category 5 unshielded twisted-pair (UTP) cabling, 100BaseTX supports high speed signaling and is relatively inexpensive. Because it uses four wires for data transmission and the same packet format, packet length, error control, and management information as 10BaseT, 100BaseTX can be made to communicate with slower 10BaseT equipment when routed through a switch.

This backwards compatibility is one of 100BaseTX's major advantages over other forms of Fast Ethernet; it allows critical, speed-dependent network segments to be upgraded to 100BaseTX speeds as needed without re-wiring, refitting, and retraining an entire site. Networks can now mix both slow and fast network segments for different users or departments. Publishing, R&D, video, multimedia, or accounting departments can enjoy a 100Mbps pace, while other corporate segments can operate at slower and more affordable 10Mbps speeds.

BRIDGE GROUPS SUPPORTED

The Switch supports the following four groups of Bridge MIB (RFC1493):

• The dot1dBase Group a mandatory group that contains the objects appli- cable to all types of bridges.

• The dot1dStp Group contains the objects that denote the bridge's state, with respect to the Spanning Tree Protocol. If a node does not implement the Spanning Tree Protocol, this group will not be implemented. This group is applicable to any transparent only, source route, or SRT bridge that implements the Spanning Tree Protocol.

• The dot1dTp Group contains objects that describe the entity's transparent bridging status. This group is applicable to transparent operation only and SRT bridges.

• The dot1dStatic Group contains objects that describe the entity's destina- tion-address filtering status. This group is applicable to any type of bridge which performs destination-address filtering.

Gigabit Ethernet runs at speeds of 1Gbps (Gigabit per second), ten times faster than 100Mbps Fast Ethernet, but it still integrates seamlessly with 100Mbps Fast Ethernet hardware. Users can connect Gigabit Ethernet hardware with either fiber optic cabling or copper Category 5 cabling, with fiber optics more suited for network backbones. As the new Gigabit standard gradually integrates into existing networks, current computer applications will enjoy faster access time for network data, hardware, and Internet connections.

Fiber optic cabling is made from flexible, optically efficient strands of glass and coated with a layer of rubber tubing, fiber optics use photons of light instead of electrons to send and receive data. Although f iber is physically capable of carrying tetrabits of data per second, the signaling hardware currently on the market can handle no more than a few gigabits of data per second.

Fiber cables come in different with two main connector types. The most commonly used fiber optic cable is multi-mode f iber cable (MMF), with a 62.5 micron fiber optic core. Single-mode fiber cabling is somewhat more efficient than multi-mode but far more expensive, due to its smaller optic core that helps retain the intensity of traveling light signals. A fiber connection always require two fiber cables: one transmits data, and the other receives it.

Each fiber optic cable is tipped with a connector that fits into a f iber port on a network adapter, hub, or switch. In the U. S., most cables use a square SC connector that slides and locks into place when plugged into a port or connected to another cable. In Europe, the round ST connector is more prevalent.

There are different grades, or categories, of twisted-pair cabling. Category 5 is the most reliable and is highly recommended. Straight-through cables are used for connecting computers to a hub. Crossover cables are used for connecting a hub to another hub (there is an exception: some hubs have a built-in uplink port that is crossed internally, which allows you to link or connect hubs together with a straight-through cable instead).

You can buy pre-made Category 5 cabling, or cut and crimp your own. Category 5 cables can be purchased or crimped as either straight-through or crossover cables. A Category 5 cable has 8 thin, color-coded wires inside that run from one end of the cable to the other. All 8 wires are used. In a straight-through cable, wires 1, 2, 3, and 6 at one end of the cable are also wires 1, 2, 3, and 6 at the other end. In a crossover cable, the order of the wires change from one end to the other: wire 1 becomes 3, and 2 becomes 6. See the diagrams

on the next page for more detailed information on straight-through and crossover cabling.

To determine which wire is wire number 1, hold the cable so that the end of the plastic RJ-45 tip (the part that goes into a wall jack first) is facing away from you. Face the clip down so that the copper side faces up (the springy clip will now be parallel to the floor).When looking down on the copper side, wire 1 will be on the far left.
