Introduction

Chapter 1: Introduction

Thank you for choosing the Linksys Business Series Smart Gigabit Ethernet Switch.

The new Linksys Business Series Smart Gigabit Ethernet Switches are cost-effective switching solutions ideal for small businesses, the network edge, or workgroups within larger organizations. These easy-to-install, highspeed switches offer many of the same Quality of Service and Security features found in more expensive full Layer 2 managed switches but without their complexity. The Smart Switches offer the following interfaces:

The SLM2024 and SLM2048 offer twenty four (24) or

•

forty eight (48) 10/100/1000 Gigabit copper ports, with two (2) shared copper or optical (SFP) uplink interfaces for connecting the switch to the core network.

The SLM224G, SLM224P, SLM248G, and SLM248P

•

offer twenty four (24) or forty eight (48) 10/100 copper ports, with two (2) shared Gigabit copper or optical (SFP) uplink interfaces for connecting the switch to the core network.

The Smart Switch’s simplified user interface is an intuitive management tool enabling you to quickly utilize the comprehensive feature-set of the switch, resulting in a better optimized network.

For Wireless or VoIP deployments, the SLM224P and SLM248P support the IEEE802.3af standard for Power over Ethernet (PoE). This eliminates the need for additional power cables and the need for a nearby power outlet, thereby making installation simple and inexpensive, allowing networking devices like cameras and Wireless Access Points to be positioned in optimal locations like in ceilings and walls -- even outdoors.

security by keeping sensitive data separated from other workgroups on the network..

Network Security is an absolute requirement for any business and preventing unauthorized access to the company network is business-critical. The Smart Switch secures the network through 802.1X port authentication which prompts end-users to provide their username and password before they are permitted to pass data. User access can also be controlled through the Smart Switch’s MAC-Based Filtering capability which allows network access only to those devices or workstations that have been authorized as identified by their MAC (Media Access Control) address. The Many-to-One or One-to-One Port Mirroring feature of the Smart Switch enables you to monitor the type of traffic being transmitted on the network.

The Smart Switch includes features for quickly expanding and growing your network. To substantially increase network throughput speeds, especially useful for companies whose employees are routinely backing up their hard drives to a company server or storage platform, the Smart Switch supports Link Aggregation which allows multiple high-bandwidth trunks between switches to be set up. Link Aggregation also provides a level of availability and redundancy as traffic will continue to flow even if one of the network links breaks. The Smart Switch’s Spanning Tree Protocol support (STP) and Storm Control features help to control planned or inadvertent cable loops when switches are connected to one another. These loops can cause broadcast or multicast storms in the network and severely limit its performance. With these features, you can confidently build a mesh of switches and quickly expand your network to support your growing workforce.

The Smart Switch includes numerous QoS features to ensure that traffic is prioritized properly to deliver the best possible user experience for real time applications like voice and video or bandwidth intensive graphic/ video file uploads or downloads. With its IGMP Snooping feature, the Smart Switch limits IP multicast traffic (real time presentations, videoconferences, on-line gaming) to only the ports that have requested it enabling the rest of the network to operate at peak efficiency. Additional QoS capabilities like IEEE 802.1p Priority Tagging, DSCP (Differentiated Services Code Point), and 4 hardware queues also maintain quality for real-time applications like voice and video. Network traffic can be optimized with the switch’s 802.1Q VLAN (Virtual LAN) support which enables you to quickly segregate network traffic by department or workgroup. VLANs also provide an additional layer of

auto-sensing, Ethernet network ports, which use RJ-45 connectors. The Fast Ethernet ports support network speeds of 10 Mbps, 100 Mbps, or 1000 Mbps. They can operate in half- and fullduplex modes. Auto-sensing technology enables each port to automatically detect the speed of the device connected to it (10 Mbps, 100 Mbps, or 1000 Mbps), and adjust its speed and duplex accordingly.

miniGBIC (1-2) The miniGBIC (gigabit interface

converter) port is a connection point for a miniGBIC expansion module, so the Switch can be uplinked via fiber to another switch. The MiniGBIC port provides a link to a high-speed network segment or individual workstation at speeds of up to 1000 Mbps.

To establish a Gigabit Ethernet connection using a miniGBIC port, you will need to install a MGBT1, MGBSX1, or MGBLH1 Gigabit expansion module and use Category 5e cabling or fiber optic cabling.

To establish a Fast Ethernet connection using a miniGBIC port, you will need to install a MFEFX1 (100BASE-FX) or MFELX1 (100BASE-LX) 100SFP Transceiver and use fiber optic cabling.

NOTE: On the SLM2048, MiniGBIC ports are

shared with standard ports. If a miniGBIC port is used, then the shared standard port on the Switch cannot be used. The following table defines the shared port mapping of the SLM2048 Switch.

Pre-Installation Considerations

Fast Ethernet Considerations

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

Full-Duplex Considerations

The Switch provides full-duplex support for its RJ-45 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).

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category

5) or Category 6 cable should be used. The Category 5e specification includes test parameters that are only recommendations for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3ab standards.

Positioning the Switch

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

Hub† Hub 5 meters (16.4 feet)

Switch or Hub† Computer 100 meters (328 feet)

A hub refers to any type of 100 Mbps hub. A 10 Mbps hub connected

†

to another 10 Mbps hub can span up to 100 meters (328 feet).

Business Series Smart Gigabit Ethernet Switch

Make sure that the Switch is accessible and that the

•

cables can be connected easily.

Keep cabling away from sources of electrical noise,

•

power lines, and fluorescent lighting fixtures.

Position the Switch away from water and moisture

•

sources.

To ensure adequate air flow around the Switch, be

•

sure to provide a minimum clearance of two inches (50 mm).

Do not stack free-standing Switches more than four

•

units high.

Placement Options

There are two ways to physically install the Switch, either set the Switch on its four rubber feet for desktop placement or mount the switch in a standard-sized, 19-inch wide, 1Uhigh rack for rack-mount placement.

Attaching the Brackets

Follow the same steps to attach the other bracket to

3. the opposite side.

After the brackets are attached to the Switch, use

4. suitable screws to securely attach the brackets to any standard 19-inch rack.

When rack-mounting the Switch, please observe the following guidelines

Elevated Operating Ambient If installed in a closed

•

or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

Reduced Air Flow Installation of the equipment

•

in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

Mechanical Loading Mounting of the equipment in

•

the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

Circuit Overloading Consideration should be given

•

to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

Reliable Earthing Reliable earthing of rack-mounted

•

equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).

VLAN Management

A VLAN is a group of ports that can be located anywhere in the network, but communicate as though they belong to the same physical segment.

VLANs help to simplify network management by allowing you to move devices to a new VLAN without having to change any physical connections. VLANs can be easily organized to reflect departmental groups (such as Marketing or R&D), usage groups (such as e-mail), or multicast groups (used for multimedia applications such as videoconferencing). You can create up to 128 VLANs on the Switch.

VLAN Management > Create VLAN

The Create VLAN screen lets you create and configure global parameters for VLANs.

VLAN Management > Port Settings

The Port Settings screen allows you to configure the ports in a VLAN.

Security > Port Security

The Port Security screen is used to configure a port’s security settings.

Security > Ports Security

Network security can be increased by limiting access on a specific port only to users with specific MAC addresses. MAC addresses can be dynamically learned or statically configured.

Locked port security monitors both received and learned packets that are received on specific ports. Access to the locked port is limited to users with specific MAC addresses. These addresses are either manually defined on the port, or learned on that port up to the point when it is locked. When a packet is received on a locked port, and the packet’s source MAC address is not tied to that port (either it was learned on a different port, or it is unknown to the system), the protection mechanism is invoked, and can provide various options. Unauthorized packets arriving at a locked port are either:

Forwarded

•

Discarded

•

Cause the port to be shut down

•

Locked port security also enables storing a list of MAC addresses in the configuration file. The MAC address list can be restored after the device has been reset.

Learning Mode Defines the locked port type. This field

is enabled only if Lock Interface is not selected. The possible values are:

Classic Lock Locks the port using the classic lock

•

mechanism. The port is immediately locked, regardless of how many addresses have already been learned.

Limited Dynamic Lock Locks the port by deleting

•

the current dynamic MAC addresses associated with the port. The port learns up to the maximum number of addresses allowed on the port. Both relearning and aging MAC addresses are enabled.

In order to change the Learning Mode, the Lock Interface must be unselected. Once the Learning Mode is changed, the Lock Interface can be reinstated.

Max Entries Specifies the number of MAC addresses

that can be learned on the port. This field is enabled only if Learning Mode is set to Limited Dynamic Lock. The default value is 1.

Action on Violation Indicates the action to be applied to

packets arriving on a locked port. The possible values are:

Discard Discards packets from any unlearned source.

QoS

Network traffic is usually unpredictable, and the only basic assurance that can be offered is best effort traffic delivery. To overcome this challenge, Quality of Service (QoS) is applied throughout the network. This ensures that network traffic is prioritized according to specified criteria, and that specific traffic receives preferential treatment. QoS in the network optimizes network performance and entails two basic facilities:

Classifying incoming traffic into handling classes, based on an attribute, including:

The ingress interface

•

Packet content

•

A combination of these attributes

•

Providing various mechanisms for determining the allocation of network resources to different handling classes, including:

Configuration Using the Web-based Utility

The assignment of internal resources

•

Traffic shaping

•

The terms Class of Service (CoS) and QoS are used in the following context:

CoS provides varying Layer 2 traffic services. CoS

•

refers to classifying traffic into traffic classes, where each class is handled as an aggregate whole, with no per-flow settings. CoS is usually related to the 802.1p service that classifies flows according to their Layer 2 priority, as set in the VLAN header.

QoS refers to Layer 2 traffic and above. QoS handles

•

per-flow settings, even within a single traffic class.

The QoS facility involves the following elements:

Traffic Classification—Classifies each incoming packet

•

as belonging to a given traffic class, based on the packet contents and/or the context.

Assignment to Hardware Queues—Assigns incoming

•

packets to forwarding queues. Packets are sent to a particular queue for handling as a function of the traffic class to which they belong, as defined by the classification mechanism.

Traffic Class-Handling Attributes—Applies QoS/CoS

Spanning Tree

Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP also provides one path between end stations on a network, eliminating loops.

Loops occur when alternate routes exist between hosts. Loops in an extended network can cause bridges to forward traffic indefinitely, resulting in increased traffic and reducing network efficiency.

The Switch supports the Classic STP version of STP, which provides a single path between end stations, avoiding and eliminating loops.

Appendix A: About Gigabit Ethernet and Fiber Optic Cabling

Gigabit Ethernet

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 5e cabling, with fiber optics more suited for network backbones. As the Gigabit standard gradually integrates into existing networks, current computer applications will enjoy faster access time for network data, hardware, and Internet connections.

About Gigabit Ethernet and Fiber Optic Cabling

Fiber Optic Cabling

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 fiber is physically capable of carrying terabits 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 with two main connector types. The most commonly used fiber optic cable is multi-mode fiber 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 fiber port on a network adapter, hub, or switch. In the USA, 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.

For Gigabit Ethernet, you must use the Linksys MGBT1, MGBSX1, or MGBLH1 miniGBIC modules with the Linksys Gigabit Switches. The MGBSX1 and the MGBLH1 require fiber cabling with LC connectors, and the MGBT1 requires a Category 5e Ethernet cable with an RJ-45 connector.

For Fast Ethernet, you must use the MFEFX1 (100BASE-FX) or MFELX1 (100BASE-LX) SFP transceivers.

QoS (Quality of Service) Provides policies that contain sets of filters (rules). QoS allows network managers to decide how and what network traffic is forwarded according to priorities, application types, and source and destination addresses.

Static IP Address A fixed address assigned to a computer or device that is connected to a network.

STP (Spanning Tree Protocol) Prevents loops in network traffic. The Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP provides one path between end stations on a network, eliminating loops.

Subnet (Sub-network) Subnets are portions of a network that share a common address component. In TCP/IP networks, devices that share a prefix are part of the same subnet. For example, all devices with a prefix of

157.100.100.100 are part of the same subnet.

Subnet Mask An address code that determines the size of the network.

Switch Filters and forwards packets between LAN segments. Switches support any packet protocol type.

TACACS+ (Terminal Access Controller Access Control System Plus) Proprietary Cisco enhancement to Terminal

Access Controller Access Control System (TACACS). Provides additional support for authentication, authorization, and accounting.

TCP/IP (Transmission Control Protocol/Internet Protocol) A set of instructions PCs use to communicate

over a network.

Telnet A user command and TCP/IP protocol used for accessing remote PCs.

TFTP (Trivial File Transfer Protocol) A version of the TCP/IP FTP protocol that has no directory or password capability.

Throughput The amount of data moved successfully from one node to another in a given time period.

Trunking Link Aggregation. Optimizes port usage by linking a group of ports together to form a single trunk (aggregated groups).

TX Rate Transmission Rate.

Glossary

UDP (User Data Protocol) Communication protocol that transmits packets but does not guarantee their delivery.

Upgrade To replace existing software or firmware with a newer version.

Upload To transmit a file over a network.

URL (Uniform Resource Locator) The address of a file

located on the Internet.

VLAN (Virtual Local Area Networks) Logical subgroups that constitute a Local Area Network (LAN). This is done in software rather than defining a hardware solution.

WAN (Wide Area Network) Networks that cover a large geographical area.

Wildcard Mask Specifies which IP address bits are used, and which bits are ignored. A wild card mask of 255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that all the bits are important.

For example, if the destination IP address is 149.36.184.198 and the wildcard mask is 255.36.184.00, the first two bits of the IP address are used, while the last two bits are ignored.
