Introduction

This chapter introduces the IntraCore architecture, then gives a description

of the chassis and the various modules that can be installed in the IntraCore

8000. There are also tables of the key features, default settings, and

specifications of the IntraCore 8000, and explanations of the different LED

indicators used by the various modules.

IntraCore Architecture Overview

Asanté has developed the IntraCore™ Architecture to meet the needs of

multi-service networks that support all applications and data types. The

architecture is standards-based and provides

G multi-vendor inter-operability
G a migration path from current systems
G investment protection

With the IntraCore Architecture, Asanté has found innovative ways of

embracing industry standards and technology advances to create products

capable of meeting real world requirements for converged, multi-service

networks.

The overall design incorporates a family of tightly integrated ASICs,

designed as system building blocks. These building blocks enable the rapid

development of advanced networking systems that are timed to meet market

requirements. The architecture ensures consistent high performance as

systems scale their capacity and feature capability. This approach extends

the useful life of the system and protects customer investments.

The Core Switching Engine

The Core Switching Engine is the centerpiece for all IntraCore products.

Based on advanced silicon ASICs, the Core Switching Engine is a high

performance, non-blocking, multi-gigabit switching fabric with scalable

bandwidth capacity. The Core Switching Engine is data format independent

and can support either frame or cell based interfaces. This capability is

becoming increasingly important as enterprise (primarily frame-based) and

service provider (primarily cell-based) networks move closer together.

Page 1-1

Introduction

Infrastructure Connectivity

The second key element of the architecture is Infrastructure Connectivity.
IntraCore specifies standards based, high performance, cost effective
technologies for connectivity among devices in the network.

In the LAN –

At the network edge, Layer 2 switched 10/100/1000 Ethernet meets the
requirements for high-speed connectivity of desktop computers and scalable,
cost effective data transmission for trunks to the network core.

In the network core, Layer 2/3+-switched 10/100/1000 Ethernet meets the
requirements for high speed, scalable, cost effective data transmission and
support for all multi-service data types. High performance servers can be
centrally located for added physical security.

Throughout the LAN, advanced queuing techniques combined with multiple
priority levels and support for industry standard 802.1Q and 802.1p enable
Quality of Service within the network.

In the MAN/WAN –

Long haul Gigabit Ethernet, ATM, and Packet over SONET meet the
requirements for all of the following:

G scalable, cost effective data transmission

G support for all multi-service data types

G service provider inter operability

The IntraCore Product Family

The Asanté IntraCore architecture is the basis for a family of switching

system products in fixed, stackable and chassis form factors that allow

customers to integrate telephony, video and data applications. Initially, two

systems are offered that provide high performance, high port-count, Layer 2

switching. Additional configurations will be introduced to offer advanced

Layer 3 and above routing, traffic classification, advanced QoS, higher

bandwidth and port capacity. All systems will be consistent in their

Introduction

operation and management allowing customers to seamlessly deploy any
model in their network.

Edge Switches

Edge Switches provide the first point of connectivity to the network.
Connecting to an Enterprise Switch in the network core, Edge Switches
provide aggregation of traffic from desktop computers over high capacity
trunks. The initial product introduced in the Edge Switch category is the
IntraCore 8000.

The IntraCore 8000 is a stackable, high performance solution for enterprise
edge applications. Each stack supports up to 192 10/100Mbps switched
Ethernet connections for cost-effective high-density connectivity in wiring
closets. The system can operate as a stand-alone network or be used in
combination with IntraCore 8000 in the backbone.

Enterprise Switches

In the network core, Enterprise Switches are deployed to aggregate traffic
from wiring closets and provide high-speed connectivity to network servers.
Typically these switches are modular in form factor, and can be easily
upgraded or reconfigured. This flexibility provides for customized
configurations to meet a wide variety of requirements. The initial product
introduced in this category is the IntraCore 9000.

switched Gigabit Ethernet ports and 24 10/100 switched Ether­net ports in a single stacking unit. This saves space in crowded
equipment rooms.

ASIC-based packet processing provides wire speed perfor­mance on all interfaces.

The system supports current requirements for multi-service
voice, video, and data applications with bandwidth to spare.
The high-capacity backplane is designed so that it may be
scaled up to 80 Gbps, extending the useful life of the chassis.

The “application aware” system ensures that mission critical
applications get the bandwidth and priority they need, even
under heavy traffic conditions. When network congestion
occurs, low latency requirements are managed by the system.

Each stack unit supports three option slots that can be custom­ized to meet customer configuration requirements. Unique
stacking design delivers scalable system bandwidth assuring
maximum system performance regardless of configuration.

Expansion modules can be mixed and matched in any configu­ration and quantity to meet design requirements. You can add
capacity whenever your business requires it.

Installation Options The system can be rack-mounted to save space.

The two GBIC Gigabit Ethernet modules can be configured
with any combination of 1000SX, 1000LX or 1000LX (Long
Haul) GBIC interfaces. Either Asanté or third party GBIC inter­faces can be used, and the interfaces can be “hot swapped.”
This means that GBIC interfaces can be re-deployed based on
the user’s applications.

Stacking Switches

Stacking Switches

Up to four IntraCore 8000 switches may be connected within a stack. In each

of the different configurations, bandwidth increases to meet the growth of

traffic.

Two Stack Configuration

If you wish to add a single switch to create a stack of two, take the following

steps.

1 Mount the second switch in the rack above the first

switch, or place it on top of the first switch.

2 Connect the 20-pin stacking cable provided by Asanté

from the Stack Connector module on the back of the first
switch to the Stack Connector module on the second
switch.

K Note: Do not use any cable but the IntraCore 8000

stacking cable supplied with your unit. If you need
additional cables, contact Asanté support (see Appen­dix A, “Technical Support,” for details).

Three or Four Stack Configuration

Before stacking three or four IntraCore 8000 switches, you must obtain a

Stack Matrix module from Asanté. IntraCore 8000 switches come equipped

with a single-port Stack Connector module. On one of the switches, the

Stack Connector module must be replaced with a 3-port Stack Matrix

module.

To create a stack of three or four IntraCore 8000 switches, use the following

procedure.

1 In the original switch (bottom), remove the (single-port)

Stack Connector module from the back of the switch and
replace it with a (3-port) Stack Matrix module.

2 Mount the other switches in the rack above the first one,

or place them on top of the first switch.

Page 2-5

Installation and Setup

3 Connect the Stack Matrix module on the first switch to

the Stack Connector modules on the other switches. Use
the 50-pin stacking cables provided by Asanté, as shown
in Figure 2-1.

K Note: Do not use any cable but the IntraCore 8000

stacking cable supplied with your unit. If you need
additional cables, contact Asanté support (see Appen­dix A, “Technical Support,” for details).

Figure 2-1 Four stack configuration

When you have cabled the switches together, proceed with network cabling,
as described in “Connecting to the Network” earlier in this chapter.

Page 2-6

Installing Port Expansion Modules

Installing Port Expansion Modules

Up to three optional port expansion modules can be installed in the IntraCore

8000, in addition to a stack matrix module. (A stack matrix module is needed

only if more than two units are stacked together. See “Stacking Switches.”)

To install any combination of Gigabit Ethernet Switch (GBIC) modules and

8-port 10/100 Switch modules, use the following procedure.

I Important: Make sure the IntraCore 8000 is properly

installed in an equipment rack or resting on a flat, stable
surface. Also make sure the power cord is disconnected
for initial installation.

1 Remove the cover plate from the slot where you intend to

install the expansion module.

2 Align the bottom of the expansion module with the rails

inside the IntraCore 8000 slot, as shown in Figure 2-2.

3 Slide the module into the slot until it stops, then push the

module in gently until it seats with the connector.

Figure 2-2 Installing port expansion module

4 Tighten the thumbscrews at the ends of the module’s face

plate. Use a straight-bladed screwdriver so the thumb­screws cannot be loosened by hand.

Installation of the module is complete. Repeat this procedure for each

module you have purchased.

I Important: Do not remove modules from the IntraCore

8000 unless you are a qualified System Administrator.

Page 2-7

Installation and Setup

Installing GBIC Interfaces

If you have installed Gigabit Ethernet switch modules, you must install
GBIC interfaces. Instructions for installing, removing, and maintaining
GBIC interfaces are provided in this section.

K

Note: GBICs are hot-swappable.

Installing a GBIC

To install a GBIC interface into a Gigabit Ethernet module:

1 Remove the GBIC from its protective packaging.

2 Grip the sides of the GBIC with your thumb and forefin-

ger, then insert the GBIC into the slot on the front of the
Gigabit Ethernet module.

3 Slide the GBIC into the slot until you hear or feel a click.

The click indicates that the GBIC is locked into the slot.

4 When you are ready to attach the fiber-optic cable,

remove the plugs from the GBIC and save them for future
use.

Removing a GBIC

To remove a GBIC interface from a Gigabit Ethernet module:

1 Disconnect the fiber-optic cable from the GBIC SC-type

connector.

2 Release the GBIC from the slot by simultaneously

squeezing the plastic tabs on both sides of the GBIC.

3 Slide the GBIC out of the slot.

4 Install the plugs in the GBIC optical bores, and place the

GBIC in protective packaging.

Page 2-8

Connecting Power

GBIC Care and Handling

Follow these GBIC maintenance guidelines:

G Unnecessary removal and insertion of a GBIC can lead to its pre-

mature failure. A GBIC has a lifetime of 100 to 500 removals/
insertions.

G GBICs are static-sensitive. To prevent ESD damage, follow your

normal board and component handling procedures.

G GBICs are dust-sensitive. When the GBIC is stored or when a

fiber-optic cable is not plugged in, always keep plugs in the GBIC
optical bores.

G Use an alcohol swab or Kim-Wipe to clean the ferrules of the opti-

cal connector. The most common source of contaminants in the
optical bores is debris picked up from the optical connectors.

Connecting Power

To connect power to the IntraCore 8000, use the following procedure.

I Important: Carefully review the power requirements on

page 2-1 before connecting power to the IntraCore 8000.

1 Plug one end of the supplied power cord into the power

connector on the back of the unit.

2 Plug the other end into a grounded AC outlet.

The front panel LEDs blink and the Power LED illumi­nates. The IntraCore 8000 is ready for connection to the
network.

I Important: If the power does not come on, refer to

Appendix A, “Troubleshooting.”

Page 2-9

Installation and Setup

Connecting to the Network

The IntraCore 8000 unit may be connected to an Ethernet network, with the
unit powered either on or off. Use the following procedure to make your
network connections.

1 Connect network devices to the IntraCore 8000, follow-

ing the cable guidelines outlined below.

2 After the unit is connected to the network, it can be con-

figured for management capabilities. See “Configuring
for Management” later in this chapter.

10/100BaseX Ports Cabling Procedures

The 8 fixed ports on each 10/100 module allow for the connection of
10Base-T or 100Base-TX network devices. The ports are compatible with
IEEE 802.3 and 802.3u standards.

I Important: The IntraCore 8000 must be located within

100 meters of its attached 10Base-T or 100Base-TX

fiber media up to 5 kilometers long.

Table 2-4 1000BaseX cabling requirements

Configuring for Management

To use the IntraCore 8000 as a managed switch, it must be configured with

an IP address. This can be accomplished in one of two ways:

G automatically using BootP (default)
G manually via the unit’s Console port

I Important: For security reasons, you should also

change the SNMP community strings before putting the
IntraCore 8000 on your network. For instructions, see
“Changing Community Strings” on page 3-17.

BootP Configuration

The IntraCore 8000 is shipped with BootP support. If your network contains

a BootP server configured with available, valid IP addresses, BootP allows

the IntraCore 8000 to be configured automatically with an IP address when

the IntraCore 8000 is connected to the network and is powered on. Use the

following procedure to set up BootP.

I Important: BootP configuration works only if the

IntraCore 8000 does not have an IP address assigned to it.

1 Make sure your network has a BootP server configured

with a valid IP address entry for the IntraCore 8000.

Page 2-11

Installation and Setup

2 When the IntraCore 8000 is connected to the network and

is powered on, it automatically transmits a BootP request
across the network (up to 10 times) until it receives a
valid IP address from the BootP server.

3 After an IP address is received, the IntraCore 8000 can be

managed via in-band access. For more information, see
Chapter 3, “Configuration.”

To verify that a valid IP address was received, try to ‘ping’ the IntraCore

8000. If you can access the IntraCore 8000, it is properly configured with an
IP address.

For more information on using BootP, see “Bootstrap Configuration” in
Chapter 3.

Connecting To a Console

To make the cable connection from a terminal to the console port of the
IntraCore 8000, use the following procedure.

1 Using a straight-through RS-232 cable with a 9-pin male

D-subminiature plug at one end, connect a terminal or
workstation (PC or Macintosh) running a terminal emula­tor to the console port on the front of the IntraCore 8000.

2 Make sure both units are powered on.

If using a PC with a terminal emulator, make sure it is
configured with the following terminal settings:

G Baud: 9600
G Data Bits: 8
G Parity: None
G Stop Bits: 1
G Flow Control: None

3 Once connected, the Local Management Main Menu

appears on the terminal screen.

For further information on setting an IP address for configuration of a
terminal, or a PC running a VT100 terminal or emulator (such as
HyperTerminal, ProComm, or ZTerm), see “System IP Configuration” in
Chapter 3.

Either of these banks may be the Boot Bank, which is the bank from which
the runtime code will be loaded the next time the IntraCore 8000 is booted.

When downloading new runtime image codes, you may specify either of the
two banks as the Destination Bank in which the new code will be loaded.

Page 3-11

Configuration

Loading Software Locally

The IntraCore 8000 will always boot locally unless you set it to boot load
remotely. It would then download the new image code and reset to load
locally.

1 Open the Bootstrap Configuration Menu by typing b in

the Configuration Menu.

2 Type a in the Bootstrap Configuration Menu if you need

to toggle the Boot Bank setting for the next boot. Typi­cally, you will want to set the boot bank to be the one on
which the latest version of the Image resides.

The IntraCore 8000 is set to load software locally from its flash memory.
This occurs whenever the unit is powered on or reset.

Setting the Maximum Broadcast or Multicast Rate

Use the following procedure to set a limit on how many packets may be
either broadcast or multicast from the current port.

1 Access the Port Configuration Menu by typing p in the

Configuration Menu.

2 Choose a module in the System Module Map.
3 In the Basic Port Configuration Menu, type a to open the

the selected port.

6 Enter the rate for broadcast or multicast and press Return.

The new maximum rate is displayed on the Advanced Port Configuration
Menu.

Enabling or Disabling 802.3x Flow Control

Use the following procedure to control traffic and avoid congestion, such as
when there is a shortage of buffer resources for the port. Flow control is
accomplished by means of standard PAUSE control frames for each port,
independent of all others. Before you can enable flow control for a port, that
port must be configured to operate in Full Duplex mode.

If you enable flow control on a port, and that port runs short of buffer
resources, the port will transmit PAUSE frames. When it receives them, the
link partner obeys these PAUSE frames. When the low-resource situation is
relieved, the port sends out PAUSE frames with zero time values. This ends
the pause staste that was imposed on the end-station.

To enable flow control, first access the Port Configuration Menu by typing p
in the Configuration Menu, then take the following steps.

1 Choose a module in the System Module Map.
2 In the Basic Port Configuration Menu, type a to open the

Advanced Port Configuration Menu.

3 To select the port for which you want to enable or disable

flow control, type s, n, or p.

4 To toggle flow control for the selected port, type f.

In the Advanced Port Configuration Menu, the Flow Control symbol for the
selected port reflects its change in state, as does the 802.3x Flow Control
setting.

I Important: When using this method of flow control,

the link partner must be configured to recognize PAUSE
frames.

Page 3-30

Global Port Configuration

Setting Port Default Priority

Use the following procedure to set the priority for a port. This priority setting
determines the order in which the port forwards packets. Each port is
associated with a traffic class: zero (0) is the lowest, and the default priority
level. Seven (7) is the highest priority level.

1 Access the Port Configuration Menu by typing p in the

Configuration Menu.

2 Choose a module in the System Module Map.
3 In the Basic Port Configuration Menu, type a to open the

and search for addresses in the IntraCore 8000’s MAC Forwarding Table. It
also provides options for displaying MAC addresses and IP/MAC binding
by individual port or by VLAN.

The MAC Forwarding Table is a table of node addresses that the IntraCore
8000 automatically builds by “learning.” It performs this task by monitoring
the packets that pass through the IntraCore 8000, checking the source and
destination addresses, and then recording the source address information in
the table.

The IntraCore 8000 uses the information in this table to decide whether a
frame should be forwarded to a particular destination port or “flooded” to all
ports other than the received port. Each entry consists of three parts: the
MAC address of the device, the port number on which it was received, and
the VLAN number.

K Note: The MAC address table can hold a maximum of

8,192 entries.

When you type d in the Configuration Menu, the Unicast Forwarding
Database Configuration Menu appears, as shown in Figure 3-17.

The Typ e field refers to the type of MAC address. The Type setting may be:

G S —þstatic (set by management, and will not age out)
G D — dynamic (learned by the switch; will be aged out)
G M — multiple (associated with multiple IP addresses, as in the

case of a router)

G I — Self (the IntraCore 8000’s MAC address)
The Pri field refers to the priority setting for the port.
The Age field indicates the amount of time remaining before an entry ages

out.

Spanning Tree Protocol

The Spanning Tree Protocol (STP) is a part of the IEEE 802.1D standard that
provides for redundancy in a bridged LAN by allowing multiple links
between points in the LAN.

Without the use of STP, multiple links in a bridged network will result in
bridging loops, which allow excess broadcast traffic that can bring down an
entire network.

Overview

The Spanning Tree Protocol reduces a network with multiple, redundant
connections to one in which all points are connected (the protocol spans the
network), but in which there is only one path between any two points (the
paths are branched, as in a tree).

For example, in a large network with multiple paths, the same message will
be broadcast over the network through multiple paths, resulting in a great
amount of extra network traffic, and possibly, network downtime. This
“closed path” or “bridged loop” among the networks can also start an
unending packet-passing process.

I Important: To explain STP more effectively, the IntraC-

ore 8000 is described as a bridge for this section of the
manual.

Page 4-1

Advanced Management

How It Works

All bridges on the network communicate with each other using special
packets called Bridge Protocol Data Units (BPDUs). The information
exchanged in the BPDUs enables bridges on the network to:

G Elect a single bridge to be the root bridge.
G Calculate the shortest path from each bridge to the root.
G Select a designated bridge on each segment, which lies closest to

the root and forwards traffic to the root.

G Select a port on each bridge to forward traffic to the root.
G Select the ports on each bridge that forward traffic, and place the

redundant ports in blocking state.

Enabling and Disabling STP

The IntraCore 8000 is shipped with spanning tree enabled on all ports by
default. To enable or disable STP on your IntraCore 8000, use the following
procedure.

1 Type c to open the Configuration Menu.
2 Open the Spanning Tree Configuration Menu by typing s

in the Configuration Menu. See Figure 4-1.

3 Type t to toggle STP to enabled or disabled.
4 If you select disabled, you are prompted to confirm the

change.
The STP status is changed. The status is displayed near

the top of the Spanning Tree Configuration Menu.

Spanning Tree Parameters

The operation of the spanning tree algorithm is governed by several
parameters. You should attempt to set these parameters only if you have
experience with the 802.1D specification.

Bridge Priority

Setting the Bridge Priority to a low value will make it more likely that the
current bridge will become the root bridge. If the current bridge is located
physically near the center of your network, you may wish to decrease the
Bridge Priority from its default value of 0x8000. If the current bridge is near
the edge of your network, it is best to leave the value of the Bridge Priority at
its default.

Hello Time

This is the time period between BPDUs transmitted by each bridge.

Page 4-3

Advanced Management

Maximum Age

Each bridge should receive regular configuration BPDUs from the direction
of the root bridge. If the maximum age timer expires before the bridge
receives another BPDU, it assumes that a change in the topology has
occurred, and it begins recalculating the spanning tree.

Forward Delay

After a recalculation of the spanning tree, the Forward Delay parameter
regulates the delay before each port begins transmitting traffic. If a port
begins forwarding traffic too soon, the network can be adversely affected.
The permitted range of the Forward Delay is 4 to 30 seconds.

K Note: The Hello Time, Maximum Age, and Forward

Delay are constrained by the following formula:

(Hello Time + 1) <= Maximum Age <= 2 x (Forward Delay -1)

In general, reducing the values of these timers will make
the spanning tree react faster when the topology changes,
but may cause temporary loops as the tree stabilizes in a
new configuration. Lengthening the timers will make the
tree react more slowly to changes in configuration but
will make an unintended reconfiguration less likely. All
of the bridges in the tree must agree on the values of these
timers, so each bridge uses the ones advertised by the
root.

Port Priority

If two ports are connected to the same segment, changing the Port Priority
increases or decreases the probability that either port will be chosen for
inclusion in the tree.

Figure 4-2 Spanning Tree Port Configuration Menu

Setting Port Priority and Path Cost

The port priority is a bridge spanning tree parameter that ranks each port.
When two or more ports have the same path cost, the STP selects the path
with the highest priority (lowest numerical value). By changing the priority
of a port, you can make it more or less likely to become the root port. The
default value is 128, and the range is 0-255.

Port path cost is the bridge spanning tree parameter that assigns a cost factor
to the port. The lower the assigned port path cost, the more likely the port is
to be accessed. The default port path cost value is a result of the equation:

path cost = 1000/LAN speed (in Mbps)

Thus, for 10Mbps ports, the assigned default port path cost is 100. For
100Mbps ports, the default port path cost is 10. And for 1000Mbps ports,
the assigned default port path cost is 1. The range is 1 to 65,535.

the port you want to configure.

3 Use the s, n, and p commands to select the port you want

to configure.

4 Type i to set the Port Priority.

Type c to set the Port Path Cost.

5 Enter a value for the setting you are making.
6 Press Return.

The new Port Priority or Port Path Cost is displayed in the Spanning Tree
Port Configuration Menu.

SNMP and RMON Management

The Simple Network Management Protocol (SNMP) may be used to manage
the IntraCore 8000. The SNMP agent supports database objects that are
defined in the following management information bases (MIBs):

G MIB II (RFC 1213)
G Bridge MIB (RFC 1493)
G RMON (RFC 1757) 4 groups - Ethernet Statistics, Ethernet His-

tory, Alarm, and Events (See next section for details)

G Private Asanté 9000 MIB

Any SNMP-based network management application can be used to manage
the IntraCore 8000. For information on management of switches, refer to
your SNMP software manual.

For details on console-based SNMP settings, see “SNMP Configuration” in
Chapter 3.

Page 4-7

Advanced Management

RMON Management

Remote Network Monitoring (RMON) allows the network manager to
gather data on the network’s traffic for future retrieval. RMON is an Internet
Standard defined in RFC1757.

Using RMON, a network monitor (also called a probe) listens to traffic on
the network and gathers statistics that may be retrieved later by a network
management station using SNMP, as described in the previous section.

The four groups of RMON that are supported by the IntraCore 8000 are
described in the following sub-sections.

The IntraCore 8000 switches provide control of the RMON groups only
through SNMP. For information on controlling RMON groups, please refer
to the documentation for your SNMP management application.

For more information about RMON, please see RFC1757, “Remote
Network Monitoring Management Information Base,” available from the
FTP site listed in Appendix A.

Ethernet Statistics Group

The Ethernet statistics group contains statistics measured on each port of the
IntraCore 8000. These are cumulative counters that start at zero each time
the IntraCore 8000 is reset. The Statistics Group is automatically
implemented by the IntraCore 8000.

Ethernet History Group

The Ethernet history group records periodic statistical samples from ports on
the IntraCore 8000 and stores them for later retrieval. A network manager
can use the data to analyze how network traffic has varied over a period of
time.

Alarm Group

The alarm group takes periodic statistical samples from variables in the
IntraCore 8000 and compares them to previously configured thresholds. If
the monitored variable crosses a threshold, an event is generated.

Event Group

The event group controls the generation and notification of events from the
IntraCore 8000. The alarm and event groups together allow the network
manager to configure RMON so that if a particular statistic (such as the
number of bad frames) goes higher than a certain level, the IntraCore 8000
will send a trap to its configured trap receivers, notifying the manager of the
