Chapter 1: Introduction

Thank you for choosing the 24-Port 10/100 + 2-Port 10/100/1000 Gigabit Advanced Smart Switch with 2 Combo SFPs.

The 24-Port 10/100 + 2-Port 10/100/1000 Gigabit Advanced Smart Switch brings a whole new level of intelligence and security to the network infrastructure at a cost effective price. It offers 24 10/100 Ethernet (copper) ports with two 10/100/1000 Gigabit Ethernet copper or optional optical (SFP) interfaces for uplinking connected users to the core network.

The 24-Port 10/100 + 2-Port 10/100/1000 Gigabit Advanced Smart Switch is able to secure the network through 802.1X port authentication and MAC filtering.

802.1X requires clients to authenticate themselves before the port will pass data.

Introduction

The Switch’s extensive QoS features makes the solution ideal for real-time applications like voice and video. The four priority queues together with Weighted Round Robin and Strict Priority scheduling techniques let network administrators quickly prioritize real-time voice and video traffic over data traffic. Individual users or applications can also be prioritized above others using various Class of Service options - by port, Layer 2 priority (802.1p), and Layer 3 priority (IP Precedence or DSCP). Intelligent broadcast, multicast, and unknown unicast storm control minimizes and contains the effects that these types storms have on regular traffic. IGMP Snooping limits bandwidth-intensive video traffic to only the requestors without flooding to all users. Incoming traffic can be policed and outgoing traffic can be shaped allowing network administrators to control network access and traffic flow.

The Switch also includes features for network expansion and faster throughput performance. Link aggregation enables network administrators to create multiple highbandwidth trunks between switches. This provides a level of reliability because the system will continue to operate if one of the links breaks. Spanning Tree (STP), Fast Spanning Tree, and Rapid Spanning Tree (RSTP) allow admins to build a mesh of switches increasing the availability of the system.

The simplified user interface provides an intuitive, secure management platform enabling admins to better utilize the comprehensive feature-set of the switch, resulting in a better optimized, more secure network.

Ethernet 1-24 These RJ-45 ports support

network speeds of either 10 Mbps or 100 Mbps, 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 (10 Mbps or 100 Mbps), and adjust its speed and duplex accordingly.

To connect a device to a port, you will need to use Category 5 (or better) network cable.

Ethernet G1-G2 The Switch is equipped with

two Gigabit RJ-45 ports that are shared with two miniGBIC ports. If a Gigabit miniGBIC port is being used, the associated RJ-45 port (Gigabit 1 or Gigabit 2) cannot be used.

Both ports support auto-negotiation, so the optimum transmission mode (half or full duplex) and data rate (10, 100, or 1000 Mbps) can be selected automatically, if this feature is also supported by the attached device. 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 802.3.x auto-negotiation of flow control, so the Switch can automatically prevent port buffers from becoming saturated.

These ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs, servers, or additional switches.

MiniGBIC (1-2) The Switch is equipped with

two miniGBIC ports that have shared Gigabit Ethernet ports (Gigabit 1 and Gigabit 2) which provide for the installation of one expansion module. These ports provide links to high-speed network segments or individual workstations at speeds of up to 1000 Mbps (Gigabit Ethernet).

To establish a Gigabit Ethernet connection using a miniGBIC port, you will need to install a MGBT1, MGBSX2, 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.

Reset The reset button can be accessed with

a straightened paper clip or similar object. The reset button has two functions:

Pre-Installation Considerations

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.

Desktop Notebook Server

Default Gateway IP address of the gateway router

between this device and management stations that exist on other network segments. (Default: 0.0.0.0)

Setup > Time

Simple Network Time Protocol (SNTP) allows the Switch to set its internal clock based on periodic updates from a time server (SNTP or NTP). Maintaining accurate time on the Switch enables the system log to record meaningful dates and times for event entries. If the clock is not set, the Switch will only record the time from the factory default set at the last boot up. When the SNTP client is enabled, the Switch periodically sends a request for a time update to a configured time server.

MAC Address Physical address of a device mapped to

this interface.

IP Configuration

IP Address Mode Specifies whether IP functionality is

enabled via manual configuration (Static) or dynamically using Dynamic Host Configuration Protocol (DHCP).

NOTE: If DHCP is enabled, IP will not function

until a reply has been received from the server. Requests will be broadcast periodically by the Switch for an IP address. If the mode is set to DHCP and a server is not available, you can reconfigure the settings by connecting the console interface directly to a computer.

Select the IP Address Mode using the drop-down menu. Selecting Static will allow you to enter a static IP address, subnet mask and default gateway using the text field provided. Selecting DHCP disables these text fields and the Switch attempts to obtain an IP address automatically from a DHCP server. The default setting is

Static.

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 256 VLANs on the Switch.

To create a range of VLANs, enter the range of the VLAN IDs to be created in to the VLAN Range fields and then click Add Range.

Network switches can provide open and easy access to network resources by simply attaching a client PC. Although this automatic configuration and access is a desirable feature, it also allows unauthorized personnel to easily intrude and possibly gain access to sensitive network data.

The IEEE 802.1X (dot1X) standard defines a port-based access control procedure that prevents unauthorized access to a network by requiring users to first submit credentials for authentication. Access to all switch ports in a network can be centrally controlled from a server, which means that authorized users can use the same credentials for authentication from any point within the network.

This Switch uses the Extensible Authentication Protocol over LANs (EAPOL) to exchange authentication protocol messages with the client, and a remote RADIUS authentication server to verify user identity and access rights. When a client connects to a switch port, the Switch responds with an EAPOL identity request. The client provides its identity (such as a user name) in an EAPOL response to the Switch, which it forwards to the RADIUS server. The RADIUS server verifies the client identity and sends an access challenge back to the client. The EAP packet from the RADIUS server contains not only the challenge, but the authentication method to be used. The client can reject the authentication method and request another, depending on the configuration of the client software and the RADIUS server. The authentication method must be MD5. The client responds to the appropriate method

24-Port 10/100 + 2-Port 10/100/1000 Gigabit Advanced Smart Switch with 2 Combo SFPs

with its credentials, such as a password or certificate. The RADIUS server verifies the client credentials and responds with an accept or reject packet. If authentication is successful, the Switch allows the client to access the network. Otherwise, network access is denied and the port remains blocked.

The operation of 802.1X on the Switch requires the following:

The Switch must have an IP address assigned.

•

RADIUS authentication must be enabled on the Switch

•

and the IP address of the RADIUS server specified.

802.1X must be enabled globally for the Switch.

•

Each Switch port that will be used must be set to dot1X

•

“Auto” mode.

Each client that needs to be authenticated must

•

have dot1X client software installed and properly configured.

The RADIUS server and 802.1X client support EAP. (The

•

Switch only supports EAPOL in order to pass the EAP packets from the server to the client.)

The RADIUS server and client also have to support the

•

same EAP authentication type – MD5. (Some clients have native support in Windows, otherwise the dot1x client must support it.)

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 source MAC address is not tied to that port (either it was learned on a different port, or it

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:

The assignment of network traffic to a particular

•

hardware queue

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 classification of traffic to traffic-classes, which are 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 perflow settings, even within a single traffic class.

QoS > CoS Settings

Class of Service (CoS) allows you to specify which data packets have greater precedence when traffic is buffered in the Switch due to congestion. The Switch supports CoS with four priority queues for each port. Data packets in a port’s high-priority queue will be transmitted before those in the lower-priority queues. You can set the default priority for each interface, and configure the mapping of frame priority tags to the Switch’s priority queues.

Port Number Indicates the port number associated with

the Static Security MAC Address that you would like to add.

Priority Specifies the CoS priority tag values, where zero

is the lowest and 7 is the highest.

Queue Defines the traffic forwarding queue to which the

CoS priority is mapped. Four traffic priority queues are supported.

QoS > Queue Settings

Scheduling Method

You can set the Switch to service the queues based on a strict rule that requires all traffic in a higher priority queue to be processed before lower priority queues are serviced, or use Weighted Round-Robin (WRR) queuing that specifies a relative weight of each queue. WRR uses a predefined relative weight for each queue that determines the percentage of service time the Switch services each queue before moving on to the next queue. This prevents the head-of-line blocking that can occur with strict priority queuing.

Strict Priority Services the egress queues in sequential

•

order, transmitting all traffic in the higher priority queues before servicing lower priority queues.

WRR Weighted Round-Robin shares bandwidth at the

•

egress ports by using scheduling weights 1, 2, 4, 8 for queues 1 through 4 respectively.

QoS > Bandwidth

This function allows the network manager to control the maximum rate for traffic transmitted or received on an interface. Rate limiting is configured on interfaces at the edge of a network to limit traffic coming out of the Switch. Traffic that falls within the rate limit is transmitted, while packets that exceed the acceptable amount of traffic are dropped.

Rate limiting can be applied to individual ports or LAGs. When an interface is configured with this feature, the traffic rate will be monitored by the hardware to verify conformity. Non-conforming traffic is dropped, conforming traffic is forwarded without any changes.

Rapid Spanning Tree Protocol (RSTP detects and uses network topologies that allow a faster STP convergence without creating forwarding loops.

Spanning Tree

The Spanning Tree Algorithm (STA) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the Switch to interact with other bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.

Spanning Tree > MSTP Properties

When using STP or RSTP, it may be difficult to maintain a stable path between all VLAN members. Frequent changes in the tree structure can easily isolate some of the group members. MSTP (which is based on RSTP for fast convergence) is designed to support independent spanning trees based on VLAN groups. Using multiple spanning trees can provide multiple forwarding paths and enable load balancing. One or more VLANs can be grouped into a Multiple Spanning Tree Instance (MSTI). MSTP builds a separate Multiple Spanning Tree (MST) for each instance to maintain connectivity among each of the assigned VLAN groups. MSTP then builds an Internal Spanning Tree (IST) for the Region containing all commonly configured MSTP bridges.

An MST Region consists of a group of interconnected bridges that have the same MST Configuration Identifiers (including the Region Name, Revision Level and Configuration Digest). An MST Region may contain multiple MSTP Instances. An Internal Spanning Tree (IST) is used to connect all the MSTP switches within an MST region. A common Spanning Tree (CST) interconnects all adjacent MST Regions, and acts as a virtual bridge node for communications with STP or RSTP nodes in the global network.

Multicast

The Internet Group Management Protocol (IGMP) runs between hosts and their immediately adjacent multicast router/switch. IGMP is a multicast host registration protocol that allows any host to inform its local router that it wants to receive transmissions addressed to a specific multicast group.

A router, or multicast-enabled switch, can periodically ask their hosts if they want to receive multicast traffic. If there is more than one router/switch on the LAN performing IP multicasting, one of these devices is elected “querier” and assumes the role of querying the LAN for group members. It then propagates the service requests on to any adjacent multicast switch/router to ensure that it will continue to receive the multicast service.

Based on the group membership information learned from IGMP, a router/switch can determine which (if any) multicast traffic needs to be forwarded to each of its ports. At Layer 3, multicast routers use this information, along with a multicast routing protocol such as DVMRP or PIM, to support IP multicasting across the Internet.

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.
