Setting up the Intel

NetStructure™ 470T

and 470F Switches

Overview

This guide provides information on configuring and managing the Intel NetStructure™ 470T and 470F Switches. It is organized into five chapters:

• Chapter 1 - Identifying and connecting the switch hardware

• Chapter 2 - Using the switch in a LAN; advanced features such as link

aggregation and VLANs

• Chapter 3 - Using Intel Device View

• Chapter 4 - Using Web Device Manager

• Chapter 5 - Using Local Management

Management

Through the switch’s built-in management you can configure the device and monitor network health. You can use any combination of the following methods to manage the switch.

• SNMP management applications like Intel Device View, LANDesk

Network Manager, HP OpenView*, and IBM Tivoli NetView* are tailored for Intel products and show a graphical representation of the device.

• Onboard management allows control over the switch without using an

SNMP application. The Web Device Manager provides a graphical interface while Local Management is a menu-driven interf ace.

• Other SNMP-compliant applications can manage the switches if you

compile the switch’s MIB files into that application.

Connection Guidelines

General

• The 470T switch is can auto-negotiate port duplex. It can operate at half-duplex or full-duplex at 100Mbps, and full-duplex at 1000Mbps. The switch matches the highest possible speed (up to 1000Mbps) of an attached device.

• The 470F operates at full-duplex and at 1000Mbps.

Cabling

NOTE

Use certified Category 5 cables to connect 1000Mbps devices to the switch.

• Use Category 5 unshielded, twisted-pair (CAT 5 UTP) cable to connect 1000Mbps or 100Mbps devices to the switch.

• Limit the cable length between devices to 100 meters (330 feet) for copper wire.

• Use a straight-through cable to connect the switch to a server or workstation.

• To connect to another switch or hub, use a crossover cable.

Straight-through vs. Crossover Cables

Switch ports are wired MDI-X, so use a straight-through cable to connect to a workstation or server (network adapter cards are wired MDI). To connect to another MDI-X port, use a crossover cable. The following pin arrangements are for the switch’s Ethernet port and the typical RJ-45 connector. The wiring diagrams illustrate how to wire a straight-through and crossover cable for 100Mbps and 1000Mbps devices.

The following example illustrates how the 470T and 470F switches can be used in a network.

In this example, the Intel NetStructure 480T Routing Switch is the backbone of the network, providing routing capability. The 470T and 470F switches provide gigabit connectivity from the 480T to the Intel Express 460T Standalone Switches through the 460T gigabit uplinks.

CHAPTER 2

Using the Intel

NetStructure™ 470T and 470F Switches

Flow Control

During heavy network activity, the switch’s port buffers can receive too much traffic and fill up faster than the switch can send the information. In cases like this, the switch tells the transmitting device to wait until the information in the buffer can be sent. This traffic control mechanism is called flow control.

The method of flow control depends on whether the port is set to full-duplex or half-duplex.

• If a port operates at half-duplex, the switch sends a collision (also called backpressure) that causes the transmitting device to wait.

• If the port operates at full-duplex, the switch sends out an IEEE 802.3x PAUSE frame.

You can enable or disable flow control for each port on the 470 switch.

Broadcast Storm Control

You can use broadcast storm control to control the amount of broadcast traffic serviced by the switch. You can prevent broadcasts from taking an excessive amount of network resources and degrading network performance.

Using the 470 Switch

To control the amount of broadcast traffic, set an upper threshold percentage for each port. The upper threshold is the percentage of the port’s total bandwidth that is available for broadcast traffic. For example, if a port’s upper threshold percentage is 4%, broadcast traffic can take up to 4% of the port’s total bandwidth.

CHAPTER 2

Intel® NetStructure™ 470T and 470F Switches User Guide

The switch checks the amount of broadcast traffic on each port every 20 seconds. If the port detects that the amount of broadcast traffic exceeds the upper threshold on two subsequent checks, the port drops all broadcast traffic.

When broadcast traffic is dropped for storm control, the switch continues to check the amount of broadcast traffic on each port. For the port to begin accepting broadcast traffic again, the amount of broadcast traffic must fall below the lower threshold percentage. The lower threshold percentage, 1%, is a factory default. If broadcast traffic falls below the lower threshold percentage when the port is checked, the switch automatically resumes servicing broadcast traffic.

When broadcast traffic servicing resumes, the switch begins checking the amount of broadcast traffic against the upper threshold.

Spanning Tree Protocol

Spanning Tree Protocol, as described in the IEEE (Institute of Electrical and Electronic Engineers) 802.1D specification, is a protocol designed to prevent loops within the network topology. A loop can occur if there is more than one path for information to travel between devices. The Spanning Tree Protocol determines the “cost” of a connection. For example, if two devices are connected by two links, spanning tree uses the connection with the lowest cost and blocks the second connection.

Spanning tree prevents loops by allowing only one active path between any two network devices at a time. However, you can also use this protocol to establish redundant links between devices that can take over if the primary link fails.

CHAPTER 2

Using the Intel

In this example, Client A can communicate with Server B over two different paths. The primary path is Path 1 because the cost of the connection between switches A and C is lower than the cost between switches A, B and C. If the primary path fails, traffic is automatically sent over the backup path.

NetStructure™ 470T and 470F Switches

Tagged Frames

The 802.1D (1998 Edition) and 802.1Q specifications published by the IEEE extended Ethernet functionality to add tag information to Ethernet frames and propagate these tagged frames between bridges. The tag can carry priority information, VLAN information, or both and allows bridges to intelligently direct traffic across the network.

Some devices don’t recognize the tagged Ethernet frames. These devices see a frame that is too big, and then discard it. When operating 802.1Q (tagbased) VLANs, you can configure the switch to work with untagged devices. For more information, see “How to configure 802.1Q VLANs” in Chapter 5.

Priority Tagging

The IEEE 802.1D (1998 Edition) specification incorporates IEEE 802.1p and defines information in the frame tag to indicate a priority level. When these tagged packets are sent out on the network, the higher priority packets are transferred first. Priority tagging (also known as Traffic Class Expediting) is usually set on the LAN adapter in a PC or switch and works with other elements of the network (switches, routers) to deliver packets based on priority. The priority level can range from 0 (low) to 7 (high).

The 470 switches can read the priority tags and forward traffic on a per port basis. The switches have two priority queues per port and queue the packet based on its priority level. For example, when a packet comes into a switch with a high-priority tag, the switch inserts the packet in its high-priority queue.

Intel® NetStructure™ 470T and 470F Switches User Guide

Although there are eight priority levels, the 470 switches can only put a packet into one of the two queues. The switch maps levels 0-3 to the low queue and levels 4-7 to the high queue. If a packet is untagged, the switch can be set to use either the high or low queue for that port. The 470 switches preserve the priority level of the packet.

Link Aggregation

Link aggregation allows you to combine from two to four (adjacent) ports so that they function as a single high-speed link. For example, link aggregation is useful when making connections between switches or connecting servers to the switch.

Note

When connecting to another switch, connect anchor port to anchor port and member port to member port.

You can use link aggregation, also known as port trunking, to increase the bandwidth to some devices. Link aggregation can also provide a redundant link for fault tolerance. If one link in the aggregation fails, the switch balances the traffic among the remaining links.

To aggregate ports, you must link an “anchor” port with an adjacent port. The 470 switches support up to four link aggregation groups (anchor ports 1,3, 5, or 7). All aggregated ports must be the same speed.

CHAPTER 2

Using the Intel

NetStructure™ 470T and 470F Switches

Guidelines

• The switch treats aggregated links as a single port. This includes spanning tree and VLAN configur ations.

• For the 470F: Anchor ports 1, 3, and 5 can each have up to four aggregated ports; anchor port 7 can have two.

• For the 470T: Anchor ports 1 and 3 can each hav e up to four aggregated ports; anchor ports 5 and 7 can each have two.

• All ports share the same settings as the anchor port. You can change anchor port settings, but you cannot configure other ports in the link.

• When a port is configured as a member of an aggregated link, it adopts the configuration of the anchor port. When a port is no longer a member of an aggregated link, the configuration is reset to the default settings (auto-negotiate speed/duplex, flow control enabled).

• If a port is part of an aggregated link, it cannot be configured as the target port for a port mirror. However, a port in an aggregated link can serve as the source port for a port mirror.

• When connecting to another switch, connect anchor port to anchor port, and member port to member port.

Using the 470 Switch

Virtual LANs

A Virtual LAN (VLAN) is a logical network grouping you can use to isolate network traffic so members of the VLAN receive traffic only from other members. Creating a VLAN is the virtual equivalent to physically moving a group of devices to a separate switch (creating a Layer 2 broadcast domain). With VLANs you can reduce broadcast traffic for the entire switch, and increase security, without changing the wiring of your network.

The 470 switches support three types of VLANs:

• Port-based

• Tag-based (IEEE 802.1Q)

• Protocol-based

CHAPTER 2

Intel® NetStructure™ 470T and 470F Switches User Guide

Port-based VLANs

Port-based VLANs are the simplest and most common form of VLAN. In a port-based VLAN, the system administrator assigns the ports to a specific VLAN. For example, the system administrator can designate ports 1, 2, and 3 as part of the engineering VLAN and ports 5, 6, 7, and 8 as part of the marketing VLAN. Port-based VLANs are easy to configure and all changes are transparent to the users because they take place at the switch. The 470 switches support a maximum of four port-based VLANs. A port can belong to only one port-based VLAN at a time.

If a user changes to another location, the system administrator reassigns the port to the new VLAN. If a switch (or hub) is connected to a port that is part of a VLAN, all devices connected to the switch are also part of the VLAN. You cannot prevent an individual device on that switch from becoming part of the VLAN.

Tag-based (IEEE 802.1Q) VLANs

The tag-based VLAN supported by the 470 switches is based on the IEEE

802.1Q specification. The specification provides a uniform way to create VLANs within a network and allows you to create a VLAN that can span across the network. Until the release of IEEE 802.1Q, it was not possible to create a VLAN across devices from different vendors.

CHAPTER 2

Using the Intel

NetStructure™ 470T and 470F Switches

The 802.1Q VLAN works by using a tag added to the Ethernet frames. The tag contains a VLAN Identifier (VID) that identifies the frame as belonging to a specific VLAN. These tags allow switches that support the 802.1Q specification to segregate traffic between devices and communicate a device’s VLAN association across switches. The example below shows a 470F switch.

There are multiple advantages to implementing 802.1Q VLANs. First, it helps to contain broadcast and multicast traffic across the switch thus improving performance. Second, ports can belong to more than one VLAN. Third, VLANs can span multiple switches that support the 802.1Q specification. Finally, it can provide security and improve performance by logically isolating users and grouping them.

A logical grouping can be mapped to a workgroup. For example, you can create a VLAN that groups all the users from the engineering department. Benefits of this logical grouping are: it improves performance by reducing traffic that belongs to a different logical group (e.g. marketing), improves security (engineering can’t see marketing), and eases moves because the user doesn’t have to be physically located in the same group to participate in the VLAN.

CHAPTER 2

Intel® NetStructure™ 470T and 470F Switches User Guide

Protocol-based VLANs

In a protocol-based VLAN, traffic is bridged through specified ports based on its protocol. Any packet using a different protocol is dropped as it enters the switch. This type of VLAN allows you to use a common protocol to communicate, yet prevents any packets that are not using the specified protocol, from entering the switch.

For example, you can attach a LAN using NetBEUI traffic to port 1 on the switch, and attach a LAN using IPX traffic to port 2 on the switch. Then, attach a router connected to the Internet, to port 8. Create an IP VLAN that incorportates ports 1, 2, and 8. The NetBEUI traffic on port 1is not passed to ports 2 or 8. The IPX traffic on port 2 is not passed to ports 1 or 8. However, computers using the IP protocol can talk freely to ports 1, 2, and

8. This allows the computers to connect to the Internet, yet not be bombarded with traffic that they do not need to see.

The 470 switches support a maximum of four protocol-based VLANs, and they can be either IP, IPX, NetBEUI, or all three combined. Each port can be a member of only one protocol-based VLAN. The example below shows a 470F switch.

Protocol-based VLANs can help optimize network traffic patterns because protocol-specific broadcast messages are sent only to computers that use that protocol. For example, if a NetBEUI VLAN is created, only NetBEUI traffic is allowed to pass through the VLAN.

CHAPTER 2

Using the Intel

NetStructure™ 470T and 470F Switches

Spanning Tree Protocol and VLANs

The 470 switches support the Spanning Tree Protocol across the entire switch, not across each VLAN. If VLANs create a redundant link between two switches and both of those switches have the Spanning Tree Protocol enabled, one of the VLANs is disabled.

The following diagram shows an example. Both Switch 1 and Switch 2 have two port-based VLANs configured. Crossover cables connect the ENG_VLAN on Switch 1 to ENG_VLAN on and Switch 2. Crossover cables also connect the MKT_VLAN on Switch 1 to the MKT_VLAN on Switch 2. When spanning tree is enabled on both switches, the redundant link between the MKT_VLANs is blocked and those VLANs can no longer communicate. The example below sho ws 470F switches.

Using the 470 Switch

GARP VLAN Registration Protocol (GVRP)

Because tag-based (IEEE 802.1Q) VLANs can span across the network, it poses a challenge for network administrators to manage changes to the VLAN. The GARP VLAN Registration Protocol (GVRP) provides a dynamic mechanism for switches to share topology information and manage changes with other switches. This saves the network administrator from having to manually propagate VLAN configuration information across switches.

CHAPTER 2

Intel® NetStructure™ 470T and 470F Switches User Guide

GARP (Generic Attribute Registration Protocol) is defined by the IEEE

802.1D (1998 Edition) specification and is the mechanism used by switches and end nodes (servers, PCs, and so on) to propagate configuration across the network domain. GVRP uses GARP as a foundation to propagate VLAN configuration to other switches. Devices that support GVRP transmit their updates to a known multicast address that all GVRP-capable devices monitor for information updates.

Note

Dynamically created VLANs are not saved in the switch’s memory. If the device sending out the GVRP updates is removed, the dynamic VLAN is removed.

Sending GVRP messages between switches accomplishes the following tasks:

• Dynamically adds or removes a port from participating in a VLAN

• Sends updates about the switch’s own VLAN configuration to neighboring

GVRP-capable devices.

• Integrates dynamic and static VLAN configurations within the same switch. For devices that don’t support GVRP, static VLAN configurations are created by the user on the switch.

When the switch is running 802.1Q VLANs, Spanning Tree Protocol is enabled for GVRP to work properly .

Internet Group Management Pr otocol (IGMP)

Normally, multicast traffic is broadcast by the switch to all ports. For multicast traffic based on TCP/IP using the IGMP protocol, the switch can optimize the broadcasting of multicast traffic by forwarding multicast traffic only to ports that require it.

IGMP Snooping is a feature that allows the switch to forward multicast traffic intelligently. The switch “snoops” the IGMP query and report messages and forwards traffic only to the ports that request the multicast traffic. This prevents the switch from broadcasting the traffic to all ports and possibly affecting network performance.

IGMP Snooping requires a router that detects multicast groups on its subnets and keeps track of group membership.
