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 and 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. There are several methods for managing this
switch; you can use one method or any combination.
• SNMP management applications like Intel Device View, LANDesk®
Network Manager, or HP OpenView* are tailored for Intel products and
show a graphical representation of the device.
®
470T Ch1.p65 3/30/00, 5:49 PM1
• Onboard management allows control over the device without using an
SNMP application. The Web Device Manager provides a graphical
interface while Local Management is a menu-driven interface.
• Other SNMP-compliant applications can manage the 470 switches if
you compile the switch’s MIB files into that application.

Connection Guidelines
General
• The 470T switch is capable of auto-negotiating port duplex. It can
operate at half- or full-duplex at 100Mbps, and full duplex at
1000Mbps. The switch matches the highest possible speed of an
attached device.
• The 470F operates at full-duplex and at 1000Mbps.
Cabling
NOTE
If you do not use certified
Category 5 cables to connect
1000Mbps devices to the switch
you may get errors.
• Use Category 5 unshielded twisted-pair (CAT 5 UTP) cable when
connecting 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. 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.

Sample Configuration
The following example illustrates how the 470T and 470F switches can be
used in a network.
In this example, the 480T functions as the backbone of the network,
providing routing capability. The 470T and 470F switches provide gigabit
connectivity from the 480T to the 460T desktop switches via the 460s’
gigabit uplinks.

Flow Control
During times of 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 so 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- or
half-duplex. If a port is operating at half-duplex, the switch sends a collision
(also called backpressure) which 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 switches.
Spanning Tree Protocol
Spanning Tree Protocol, as referenced in the IEEE 802.1D specification, is a
protocol designed to prevent any 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 works by determining 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.
Using the 470
470T Ch2.p65 3/30/00, 5:54 PM9
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 which can take over in the event
the primary link fails.
Backup Path from Client A to Server B:
Switch A –> Switch B –> Switch C
Primary Path from Client A to Server B: Switch A –> Switch C
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, then traffic is automatically sent over the backup path.

470T and 470F Switches User Guide
Tagged Frames
The 802.1D (1998 Edition) and 802.1Q specifications published by the
IEEE (Institute of Electrical and Electronic Engineers) 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, there is a way to configure the switch to work with these
untagged devices. For more information see “How to configure 802.1Q
VLANs” in Chapter 5.
Priority Packet
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 packet 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).
10
470T Ch2.p65 3/30/00, 5:54 PM10
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.
Even though 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.
CHAPTER 2
Using the Intel

NetStructure™
470T and 470F Switches
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.
Link aggregation, sometimes known as port trunking, is used 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.
Using the 470
Guidelines
• The switch treats aggregated links as a single port. This includes
spanning tree and VLAN configurations.
• 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 have 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.

CHAPTER 2
Intel® NetStructure
470T and 470F Switches User Guide
Virtual LANs
A Virtual LAN is a logical network grouping that allows you to isolate
network traffic so members of the VLAN receive traffic only from other
members. Creating a VLAN is the virtual equivalent of physically moving a
group of devices to a separate switch (creating a Layer 2 broadcast domain).
The advantage of VLANs is that you can reduce broadcast traffic for the
entire switch, and increase security, without changing the wiring of your
network.
The 470 switches support two types of VLANs:
• Port-based
• Tag-based (IEEE 802.1Q)
Port-based VLANs
This is the simplest and most common form of VLAN. In a port-based
VLAN, the system administrator assigns the switch’s 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. The advantage of port-based VLANs is that they are easy
to configure and all changes happen at the switch so they are transparent to
the users. The 470 switches support a maximum of four port-based VLANs.
A port can belong to only one VLAN at a time.
12
470T Ch2.p65 3/30/00, 5:55 PM12
If a user changes location, the system administrator reassigns the port to the
new VLAN. Another advantage is 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 exclude an individual device on that switch from
becoming part of the VLAN.
CHAPTER 2
Using the Intel
®
NetStructure™
470T and 470F Switches
IEEE 802.1Q (tag)-based VLANs
The other type of VLAN supported by the 470 switches is based on the
IEEE 802.1Q specification. The specification provides a uniform way for
creating VLANs within a network and allows the creation of a VLAN that
can also span across the network. Until the release of the IEEE 802.1Q,
VLAN implementation had been vendor-specific, so it was not possible to
create a VLAN across devices from different vendors.
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.
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 together.
Using the 470
470T Ch2.p65 3/30/00, 5:55 PM13
A logical grouping may be mapped to a workgroup. For example, you can
create a VLAN that groups all the users from the engineering department. A
benefit of this logical grouping is that it improves performance by reducing
traffic that belongs to a different logical group (i.e. marketing), improves
security (engineering can’t see marketing), and eases moves since 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
Spanning Tree and VLANs
The 470 switches support the Spanning Tree Protocol across the entire
switch, not per VLAN. If a loop occurs in a VLAN the port is disabled and
all VLAN traffic over that port is blocked.
A good example of this is seen below. 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 MRKT_VLAN on Switch 1 to the MRKT_VLAN on Switch 2. When
Spanning Tree is enabled, the redundant link between the MRKT_VLANs is
blocked and those VLANs can no longer communicate.

GARP VLAN Registration Protocol (GVRP)
Since 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 prevents the network administrator from manually
propagating VLAN configuration information across switches.
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, etc.) 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.
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 VLANs configurations within the same
switch. Static VLAN configurations are created by the user on the
switch for devices that don’t support GVRP.
It’s important to remember that dynamically created VLANs are not saved
in the switch’s memory. If the device that is sending out the GVRP updates
is removed, then the dynamic VLAN is removed.
When the switch is running 802.1Q VLANs Spanning Tree Protocol is
enabled for GVRP to work properly.

Internet Group Multicast Protocol (IGMP)
Under normal circumstances, 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 learns about the presence of
multicast groups on its subnets and keeps track of group membership.

Viewing RMON information
The remote monitoring (RMON) specification extends SNMP functionality
to look at traffic patterns on the network instead of merely looking at the
traffic for an individual device. The following RMON groups are supported:
• Group 1 (Statistics): Monitors utilization and error statistics for each
network segment (100Mbps or 1000Mbps).
• Group 2 (History): Records periodic statistical samples from variables
available in the statistics group.
• Group 3 (Alarms): Allows you to set a sampling interval and alarm
thresholds for statistics. When a threshold is passed, the switch creates
an event. For example, you might set an alarm if switch utilization
exceeds 30%.
• Group 9 (Events): Provides notification and tells the switch what to do
when an event occurs on the network. Events can send a trap to a
receiving station or place an entry in the log table, or both. For example,
when the switch experiences an RMON Event, it sends out an alarm.
The switch also keeps a log that shows a list of the RMON Events and
RMON Alarms that have occurred on the switch.
24
To view RMON statistics
1 In the Device Tree, right-click the switch’s icon, then point to RMON.
2 Click the RMON option you want to view:
You can also access RMON features by using LANDesk Network Manager,

NOTE
When configuring link
aggregation between two 470
switches, you must connect
anchor port to anchor port, and
member port to member port.
NOTE
Intel® NetStructure™ 470T and 470F Switches User Guide
Link Aggregation
Link aggregation lets you group up to four consecutive ports into a single
dedicated connection. This feature can expand bandwidth between devices
on the network, such as another switch or a server. The 470 switches
support a maximum of four link aggregation groups.
The anchor port is the base port in a link aggregation, and it is the only port
with configurable settings in the aggregation. All member ports in an
aggregation take on the settings of the anchor port.
Only consecutive ports, starting from the anchor port, can be grouped in a
link aggregation. For example, ports 1, 2, and 3 are a valid link aggregation;
ports 2, 4, and 7 are not.
On the Web Device Manager’s switch faceplate graphic, a link aggregation
is shown with its ports outlined in magenta (pink).
To create a link aggregation
1 Click the Configure Device menu, then click Link Aggregation.

5 Click Enable to make the group active.
6 Click Submit.
CHAPTER 4
Using the Web Device Manager
Static MAC Addresses
The switch has a static MAC address table that stores all the MAC
addresses that it learns from the network. The switch uses this table for
forwarding traffic to specific ports, so it does not broadcast traffic to every
port.
There are two ways to add addresses to the MAC address table:
• The switch can learn addresses from the network and add them
dynamically. Dynamic entries remain in the table only while the
associated node is active, and they are deleted if the node is inactive for
longer than a certain period of time (age-out time).
• You can manually add MAC addresses to the table. These are called
static addresses, because they remain in the table until you remove
them, even if the associated node is inactive or removed from the
network. Performance and security issues are two reasons for adding
static addresses.
To add a static MAC address to the address table
1 Click the Configure Device menu, then click Forwarding and Filtering.
NOTE
To view the switch’s address
table, click the Monitor menu,
click Advanced, and then click
MAC Address Table.

Auto-partition capability on all ports: If this option is enabled, the

while receiving data. The first time the switch receives a good packet it
then unpartitions the port. If a port is partitioned the switch can transmit
data over this port, but not receive data.

470T Ch5 - Sec 1-Nav & Config.p65 4/12/00, 10:21 AM54
Head of Line (HOL) Blocking Prevention: If this option is enabled it
prevents the forwarding of data to a port that is blocked. Normally, when
the switch sends traffic out from a port, the data goes to the port’s transmit
queue and then is sent out. If the port’s transmit queue is already busy
trying to send out data then the switch will place the waiting traffic in the
buffer memory until the port is ready to send it out.
However, if the port’s transmit queue remains full, the switch will fill up
more of the buffer with traffic waiting to be sent on that port. HOL
blocking works on the assumption that it is better to drop the traffic waiting
in the buffer than to continue using more memory and impacting
performance across all the ports.
High-priority packet service ratio: This option lets you determine how
many high-priority packets are sent out by the switch before sending a lowpriority packet. For example, a ratio of 8 high:1 low means that the switch
will send out eight high-priority packets before sending out one lowpriority packet.

Configure IGMP Snooping
Description
IGMP Snooping (Internet Group Management Protocol) 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.
470T Ch5 - Sec 1-Nav & Config.p65 4/12/00, 10:21 AM59
IGMP requires a router that learns about the presence of multicast groups
on its subnets and keeps track of group membership. It is important to
remember that multicasting is not connection oriented, so data is delivered
to the requesting hosts on a best-effort level of service.
VLAN Name (port-based or tag-based VLANs only): Displays the
VLAN for which IGMP snooping is enabled. You can also enable IGMP

This screen allows the switch to manage incoming packets that do not

VID of zero). This is for ingress traffic; it does not apply to outbound
traffic.
Untagged traffic is normally assigned to VLAN 1 (the DEFAULT_VLAN),
which includes all ports on the switch. However, if you want to send
untagged traffic on a specific port other than the default VLAN, you can
assign a different PVID.
For example, if you set a port’s PVID to 5, all untagged traffic on the port
is assigned to VID 5.
PVID: Sets the PVID for untagged devices. This is used for incoming
traffic from an untagged device.

How to configure 802.1Q VLANs
NOTE
It is important to determine which
devices on your network support
tag-based VLANs and which do
not, before you start this
procedure.
Setting up an 802.1Q VLAN is a two-step process. The first step is to create
a VLAN on the switch. The second step requires you to make sure that
tagging is set up properly for your attached devices. For those devices that
don’t support tagging an extra configuration step is required.
Step 1: Create an 802.1Q VLAN and add ports
1 From the Main Menu, select Configure VLAN.
Note: Make sure the switch’s current VLAN operation mode is set to
IEEE 802.1Q VLAN. Refer to “Configure VLAN Operation Mode” in
Chapter 5 to change the VLAN operation mode.
2 Select Create an IEEE 802.1Q VLAN and press E.
3 Type a name for the new VLAN (no spaces) and press E.
4 Type a VLAN ID and press E. The ID number can be any
number from 2 to 4094.
5 Determine if you want to allow IGMP Snooping on this VLAN. This is
important since the switch can support more 802.1Q VLANs than the
maximum of 12 IGMP Snooping sessions available.
6 Select ports to add to the VLAN. Use z to toggle the
Member field to Yes.
7 Select the NEXT button and press E.
Step 2: Configure tagging for member ports
84
470T Ch5 - Sec 2-VLANs-Monitoring-Tools.p65 4/12/00, 10:14 AM84
If the device on a particular port does not support tags, configure that port as
untagged. Configuring a device as untagged ensures that the switch removes
tags from packets before they leave the switch for the device. If you
configure a port as untagged, proceed to step 3 (Configure VLAN for
untagged devices) when you are finished with step 2.
1 Press z to select Tag or Untag for each port that is a member of
the VLAN.
2 Select the DONE button and press E.
If you configured any of the ports in the VLAN as Untagged, proceed to
step 3 to configure ports for untagged devices and associate those ports with
a PVID (port VLAN ID).
CHAPTER 5
Using Local Management
Local Management
Step 3: Configure VLAN for untagged devices
Even if the device attached to the switch doesn’t support 802.1Q tags it is
still possible for the device to participate in the VLAN. When
communicating with untagged devices the switch performs two functions:
First, it determines how to forward untagged traffic. For untagged
traffic, the switch assigns a default VID to the incoming traffic from the
untagged device. Normally, all untagged traffic received on the switch is
assigned a VLAN ID=1 or the DEFAULT_VLAN. You can change this
PVID to the VID of the VLAN you want the port to use.
Second, it strips 802.1Q tags before sending traffic to the untagged
device. When the switch needs to send traffic from a port to an untagged
device, it strips the 802.1Q tag, otherwise the untagged device may not
understand how to process the VID tag.
Use the following steps to add a untagged device to a 802.1Q VLAN.
1 Ensure that the port is a member of the VLAN. Refer to the procedure
in step 1 to add a port to a 802.1Q VLAN.
2 From the Configure VLAN menu, select Configure VLAN ID for
Untagged Devices and press E.
3 Select the port where the untagged device is connected. For example,
port 7.
4 Type the VID of the VLAN you want the port to belong to and press
E. This is the same ID number you entered in step 1.
5 Select APPLY and press E to activate the changes.
470T Ch5 - Sec 2-VLANs-Monitoring-Tools.p65 4/12/00, 10:15 AM85
By specifying a VID you set the switch to assign a particular VID to any
incoming traffic it receives on that port.
