Basic Functions
In general, the switch is responsible for switching both VLAN
tagged and untagged frames from a receiving port to one or
more transmitting ports. The switch performs multiple steps
during the switching process:
VLAN CLASSIFICATION
LEARNING
FILTERING
FORWARDING
AGING
Below is additional information about tasks that the switch
performs during unicast and multicast switching.
10
LB9030A-R2_LB9031A-R2_LB9032A-R2
UNICAST SWITCHING
VLAN CLASSIFICATION
When the switch receives a frame, it classifies the frame in one of two ways:
- If the frame is untagged, the switch classifies the frame to an associated
VLAN.
- If the frame is tagged, the switch uses the tagged VLAN ID to identify the
broadcasting domain of the frame.
LEARNING
After VLAN classification, the switch checks the <source MAC address,
VLAN> pair in the switching database (SDB) to see whether the <source
MAC address, VLAN> pair is known.
- If it is unknown, the switch inserts the <source MAC address, VLAN> into
the SDB and learns the <source MAC address, VLAN>.
- If it is known, the switch checks the <source MAC address, VLAN> for a
mismatched port ID. If the port ID associated with the <source MAC
address, VLAN> pair in the SDB is different than the receiving port, the
switch modifies the port ID in the SDB and modifies its management
database (MDB) accordingly.
FILTERING
After learning the address, the switch checks:
- Whether the source port or destination port is in the forwarding state.
- Whether the source MAC address or destination MAC address is to be
filtered.
Whether the source port ID is the same as destination port ID.
-
If any of these conditions are met, the switch drops the receiving packet.
Otherwise, it continues with the forwarding process described below.
FORWARDING
During the forwarding process, the switch checks whether the <destination
MAC address, VLAN> pair is unknown.
- If it is unknown, the switch floods the receiving frame to all ports in the
VLAN, excluding the source port.
- If it is known, the switch forwards the receiving frame to the port associated
with the <destination MAC address, VLAN> pair. At the same time, the
switch ascertains the individual’s port’s VLAN tagging/untagging
configuration and corresponding VLAN ID to render the appropriate frame
tagging when the frame is ready to be transmitted.
11
LB9030A-R2_LB9031A-R2_LB9032A-R2
MULTICAST SWITCHING
For multicast switching, the switch checks whether the received frame is a
BPDU. If a BPDU is received, the switch forwards the frame to the CPU for
processing by the spanning tree protocol. Otherwise, the switch performs the
following processes:
VLAN CLASSIFICATION
Same as for unicast switching.
LEARNING
Same as for unicast switching.
FILTERING
After learning the address, the switch checks:
- Whether the source port or destination port is not in the forwarding state.
- Whether the source MAC address or destination MAC address is to be
filtered.
If any of these conditions are met, the switch drops the receiving packet.
Otherwise, it continues with the forwarding process described below.
FORWARDING
The switch floods the received multicast frame to all ports that are in
forwarding state within the VLAN, excluding the source port. At the same time,
the switch ascertains the individual port’s VLAN tagging/untagging
configuration and corresponding VLAN ID to render the appropriate frame
tagging when the frame is ready to be transmitted.
AGING
The switch performs the aging process for the <MAC addresses, VLAN> pair
in the switching database. Once a <MAC address, VLAN> pair is aged out,
the SDB is modified.
SPANNING TREE
The switch supports one Spanning Tree per bridged network.

LB9030A-R2_LB9031A-R2_LB9032A-R2
VLAN
A virtual LAN (VLAN) is a network of computers that behave
as if they are connected to the same wire, even though they
may actually be physically located on different segments of a
LAN. VLANs are analogous to a group of end stations,
perhaps on multiple physical LAN segments that are not
constrained by their physical location and can communicate
as if they were on a common LAN.
VLANs are configured through software rather than hardware,
which makes them extremely flexible. One of the biggest
advantages of VLANs is that when a computer is physically
moved to another location, it can stay on the same VLAN
without any hardware reconfiguration.
Because VLANs are not limited by the hardware constraints
that physically connect traditional LAN segments to a network,
they can define a network into various logical configurations.
For example, VLANs can define a network by application. In
this scenario, a company might create one VLAN for
multimedia users and another for email users. VLANs can
also define a network by department. For example, a
company might have one VLAN for its Engineering
Department, another for its Marketing Department, and
another for its Account Payable Department.
VLANs can also be set up according to the organization
structure within a company. For example, the company
president might have his/her own VLAN, the executive staff
might have a different VLAN, and the remaining employees
might have yet a different VLAN.
As these examples show, VLANs offer unparalleled flexibility.
The following sections describe how deploying VLANs can
benefit organizations and reduce administration costs.
13
LB9030A-R2_LB9031A-R2_LB9032A-R2
Broadcast Containment
In traditional networks, traffic broadcasts to all network
devices, whether they are the intended recipients or not.
However, VLANs can be set up to contain only those devices
that need to communicate with each other. As a result,
VLANs significantly reduce network congestion. In addition,
VLANs prevent broadcast storms from causing network
meltdown due to volumes of traffic.
Multicast-Based Multimedia Applications
Multimedia applications, such as interactive training, video
conferencing, and news-video transmissions, require large
amounts of bandwidth. These applications are also extremely
sensitive to variable delays, which are unavoidable on a
shared Ethernet network. By defining a VLAN based on the IP
multicast address for all subscribing members on the VLAN,
sufficient bandwidth will be available for these application,
providing true multimedia on Ethernet.
Enhanced Security
Because VLANs are self-contained, only the devices within
the same VLAN can communicate with each other. If a device
in one VLAN wants to communicate with a device in another
VLAN, the traffic must go through a router.
14
LB9030A-R2_LB9031A-R2_LB9032A-R2
VLAN Membership
VLAN IMPLEMENTATION ALLOWS:
VLANs across multiple switches by using explicit or implicit tagging and the
GARP/GVRP protocol defined in IEEE802.1p and 802.1Q.
An end station’s network interface card may belong to multiple VLANs.
A switch port may be associated with multiple VLANs.
DEFINITIONS OF VLAN MEMBERSHIP
VLAN implementation allows VLAN membership to be defined based on
ports. Port-based VLANs are organized by physical port number. For
example, switch ports 1, 2, 4 and 6 can be grouped on VLAN, while server
ports 3, 5, 7 and 8 can be on another VLAN. Broadcasts from servers within
each group would only go to the members of its own VLAN. This ensures that
broadcast storms cannot cause a network meltdown due to traffic volume.
VLAN MEMBERSHIP LEARNING
Port-based VLAN is defined using a static binding between a VLAN and its
associated ports. The switch’s forwarding decision is based on the
destination MAC address and its associated port ID. Therefore, to make valid
forwarding and flooding decisions, the switch learns the relationship of the
MAC address to its related port – and thus to the VLAN – at runtime.
REMOTE VLAN LEARNING
In addition to providing network management tools that allow network
administrators to statically add and delete VLAN member ports, the switch
also supports GVRP (GARP VLAN Registration Protocol). GVRP allows for
dynamic registration of VLAN port members within switch and across multiple
switches.
Other than supporting dynamic updating of registration entries in a switch,
GVRP is used to communicate VLAN registration information to other
VLAN-aware switches, so that a VLAN member can cover a wide span of
switches on a network.
GVRP allows both VLAN-aware workstations and switches to issue and
revoke VLAN memberships. VLAN-aware switches register and propagate
VLAN membership to all ports that belong to the active topology of the VLAN.
15
LB9030A-R2_LB9031A-R2_LB9032A-R2
VLAN CONFIGURATION
The switch provides a Local/Remote Management Console
Interface for VLAN configuration and management An
SNMP-based VLAN MIB is also provided.
Intra-VLAN Communication
The switch supports intra-VLAN communication through
hardware, as described in “Basic Functions” section.
Inter-VLAN Communication
The switch supports inter-VLAN communication using
CPU-based routing software.
16
LB9030A-R2_LB9031A-R2_LB9032A-R2
GVRP
In addition to network management tools that allow network
administrators to statically add and delete VLAN member
ports, the routing switch supports GARP VLAN Registration
Protocol (GVRP). GVRP supports dynamic registration of
VLAN port members within a switch and across multiple
switches.
In addition to dynamically updating registration entries within
a switch, GVRP is used to communicate VLAN registration
information to other VLAN-aware switches, so that members
of a VLAN can cover a wide span of switches on a network.
GVRP allows both VLAN-aware workstations and switches to
issue and revoke VLAN memberships. VLAN-aware switches
register and propagate VLAN membership to all ports that are
part of the active topology of the VLAN.
17
LB9030A-R2_LB9031A-R2_LB9032A-R2
IGMP Snooping and IP Multicast Filtering
The Internet Group Management Protocol (IGMP) runs
between hosts and their immediately neighboring multicast
routers. The protocol’s mechanisms allow a host to inform its
local router that it wants to receive transmissions addressed
to a specific multicast group.
Routers periodically query the LAN to determine if known
group members are still active. If there is more than one
router on the LAN performing IP multicasting, one of the
routers is elected “querier” and assumes the responsibility of
querying the LAN for group members.
Based on the group membership information learned from the
IGMP, a router can determine which (if any) multicast traffic
needs to be forwarded to each of its “leaf” sub-networks.
Multicast routers use this information, along with a multicast
routing protocol, to support IP multicasting across the
Internet.
IGMP provides the final step in an IP multicast packet delivery
service since it is only concerned with the forwarding of
multicast traffic from the local route to group members on
directly attached sub-networks.
Routing switches support IP Multicast Filtering by:
• Passively snooping on the IGMP Query and IGMP Report
packets transferred between IP Multicast Routers and IP
Multicast host groups to learn IP Multicast group members,
and
• Actively sending IGMP Query messages to solicit IP
Multicast group members.
The purpose of IP multicast filtering is to optimize a switched
network’s performance, so multicast packets will only be
forwarded to those ports containing multicast group hosts
18
LB9030A-R2_LB9031A-R2_LB9032A-R2
members and routers instead of flooding to all ports in the
subnet (VLAN).
Routing switches with IP multicast filtering/switching
capability not only passively monitor IGMP Query and Report
messages, DVMRP Probe messages, PIM, and MOSPF
Hello messages; they also actively send IGMP Query
messages to learn locations of multicast routers and member
hosts in multicast groups within each VLAN.
Note, however, IGMP neither alters nor routes any IP
multicast packets. Since IGMP is not concerned with the
delivery of IP multicast packets across sub-networks, an
external IP multicast router is needed if IP multicast packets
have to be routed across different sub-networks.

Installation
This chapter gives step-by-step instructions about how to
install the switch:
Selecting a Site for the Switch
As with any electric device, you should place the switch
where it will not be subjected to extreme temperatures,
humidity, or electromagnetic interference. Specifically, the
site you select should meet the following requirements:
- The ambient temperature should be between 0 to 45
degrees Celsius.
- The relative humidity should be less than 90 percent,
non-condensing.
- Surrounding electrical devices should not exceed the
electromagnetic field (RFC) standards.
- Make sure that the switch receives adequate ventilation.
Do not block the ventilation holes on each side of the
switch or the fan exhaust port on the rear of the switch.
- The power outlet should be within 1.8 meters of the
switch.

Power-on Self test (POST)
The Switch performs its Power-On Self Test (POST) when the power is
switched on. During the POST, the switch CPU will:
Perform a series of diagnostic procedures to make sure the basic system is
functioning properly.
A command line prompts when you press the Esc key on a terminal
connected to the switch serial port during the POST process. Then you can
execute the following options:
DOWNLOAD RUNTIME SOFTWARE FROM SERIAL PORT0
This will download the runtime system image to the switch via the serial port.
Before selecting this option, make sure:
- A host system is running a terminal emulation program that supports the
Kermit file transfer protocol.
- The host system’s hard drive has the required binary file that will be
downloaded to the switch.
CONFIGURE THE SYSTEM
This option lets you modify any configurable parameter in the switch’s flash
ROM before the switch system boots.
RUN MANUFACTURING DIAGNOSTICS
This option is to download the manufacturer’s diagnostics. Refer to Download
Runtime Software for download requirements.
When the file transfer is completed, the target system jumps to the entry point
of the diagnostic program and starts executing the diagnostic code. The Main
Menu of the diagnostic program appears where you can initiate tests or
obtain system information. Note that user intervention is not required when a
test runs, unless an error occurs. If an error occurs during testing, you are
given the choice of continuing the diagnostics or skip the error.

26
LB9030A-R2_LB9031A-R2_LB9032A-R2
Administration Console
The administration console is an internal, character-oriented,
menu-driven user interface for performing system
administration such as displaying statistics or changing option
settings.
Using this method, you can view the administration console
from a terminal, personal computer, Apple Macintosh, or
workstation connected to the switch’s console port.
There are two ways to use this management method: direct
access or modem access. The following sections describe
these methods.
Direct Access
Direct access to the administration console is achieved by
directly connecting a terminal or a PC equipped with a
terminal-emulation program (such as HyperTerminal) to the
switch console port.
When using the management method, configure the
terminal-emulation program to use the following parameters
(you can change these settings after login):
[Default parameters]
115,200bps
8 data bits
No parity
1 stop bit
This management method is often preferred because you can
remain connected and monitor the system during system
reboots. Also, certain error messages are sent to the serial
port, regardless of the interface through which the associated
action was initiated. A Macintosh or PC attachment can use
any terminal-emulation program for connecting to the terminal
27
LB9030A-R2_LB9031A-R2_LB9032A-R2
serial port. A workstation attachment under UNIX can use an
emulator such as TIP.
Modem Access
You can access the switch’s administration console from a
PC or Macintosh using an external modem attached to the
console port. The switch management program provides
Console Port screen, accessible from the Basic
Management screen, which lets you configure parameters for
modem access.
When you have configured the external modem from the
administration console, the switch transmits characters that
you have entered as output on the modem port. The switch
echoes characters that it receives as input on the modem port
to the current administration console session. The console
appears to be directly connected to the external modem.

Web Management
The switch provides a browser interface that lets you
configure and manage the switch remotely.
After you set up your IP address for the switch, you can
access the switch’s web interface applications directly in your
web browser by entering the IP address of the switch. You
can then use your web browser to list and manage switch
configuration parameters from one central location, just as if
you were directly connected to the switch’s console port.
Web Management requires either Microsoft Internet Explorer
4.01 or later or Netscape Navigator 4.03 or later.
Netscape Navigator
If you use Netscape Navigator 4.03 or 4.04, install the Netscape JDK 1.1
Patch. Download the patch from:
http://help.hetscape.com/filelib.html#smartupdate
If you encounter problems accessing Help files when you use Netscape,
clear the browser memory cache and disk cache, and restart the browser.
Internet Explorer
If you use Internet Explorer, install the latest 4.01 Service Pack 1. This
service pack makes Internet Explorer Year 2000 compliant and fixes other
product-support issues. Download the 4.01 Service Pack 1 from the following
location:

SNMP-Based Network Management
You can use an external SNMP-based application to
configure and manage the switch. This management method
requires the SNMP agent on the switch and the SNMP
Network Management Station to use the same community
string. This management method, in fact, uses two
community strings: the get community string and the set
community string. If the SNMP Network management station
only knows the set community string, it can read and write to
the MIBs. However, if it only knows the get community string,
it can only read MIBs. The default get and set community
strings for the switch are public.
30
LB9030A-R2_LB9031A-R2_LB9032A-R2
Protocols
The switch supports the following protocols:
VIRTUAL TERMINAL PROTOCOLS, SUCH AS TELNET
A virtual terminal protocol is a software program, such as Telnet, that allows
you to establish a management session from a Macintosh, a PC, or a UNIX
workstation. Because Telnet runs over TCP/IP, you must have at least one IP
address configured on the switch before you can establish access to it with a
virtual terminal protocol.
<Note> Terminal emulation is different from a virtual terminal protocol in that you
must connect a terminal directly to the console port.
SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)
SNMP is the standard management protocol for multivendor IP networks.
SNMP supports transaction-based queries that allow the protocol to format
messages and to transmit information between reporting devices and
data-collection programs. SNMP runs on top of the User Datagram Protocol
(UDP), offering a connectionless-mode service.
Management Architecture
All of the management application modules use the same
Messaging Application Programming Interface (MAPI). By
unifying management methods with a single MAPI,
configuration parameters set using one method (e.g. console
port) are immediately displayed the other management
methods (e.g. SNMP agent of web browser).
The management architecture of the switch adheres to the
IEEE open standard. This compliance assures customers that
the switch is compatible with, and will interoperate with other
solutions that adhere to the same open standard.

LB9030A-R2_LB9031A-R2_LB9032A-R2
Menu-Driven Console Management
The switch provides a menu-driven console interface for
configuration purposes. The switch can be configured either
locally through its RS-232 port or remotely via a Telnet
session.
This chapter describes how to configure the switch using its
menu-driven console.

VLAN & PVID Perspective
There are three types of private VLAN ports: promiscuous, isolated, and
community.
1. A promiscuous port communicates with all other private VLAN ports and is
the port you use to communicate with routers, servers, and administrative
workstations.
2. An isolated port has complete Layer 2 separation from other ports within
the same private VLAN with the exception of the promiscuous port.
3. Community ports communicate among themselves and with their
promiscuous ports. These ports are isolated at Layer 2 from all other ports
in other communities or isolated ports within their private VLAN.
4. Primary VLAN conveys incoming traffic from the promiscuous port to all
other promiscuous, isolated, and community ports.
5. Isolated VLAN used by isolated ports to communicate to the promiscuous
ports.
6. Community VLAN used by a group of community ports to communicate
among themselves and transmit traffic to outside the group via the
designated promiscuous port.

47
LB9030A-R2_LB9031A-R2_LB9032A-R2
The IEEE802.1Q standard defines VLAN ID #1 as the default VLAN. The
default VLAN includes all the ports as the factory default. The default VLAN’s
egress rule restricts the ports to be all untagged, so it can, by default, be
easily used as a simple 802.1D bridging domain. The default VLAN’s domain
shrinks as untagged ports are defined in other VLANs.
