1.2.5 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:
l VLAN classification
l Learning
l Filtering
l Forwarding
l Aging
Below is additional information about tasks that the switch
performs during unicast and multicast switching.
UNICAST SWITCHING
VLAN CLASSIFICATION
When the switch receives a frame, it classifies the frame in one
of two ways:
l If the frame is untagged, the switch classifies the frame to an
associated VLAN.
1. Introduction-6
l 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.
l If it is unknown, the switch inserts the <source MAC address,
VLAN> into the SDB and learns the <source MAC address,
VLAN>.
l 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.
1. Introduction-7
FILTERING
After learning the address, the switch checks:
l Whether the source port or destination port is in the
forwarding state.
l Whether the source MAC address or destination MAC
address is to be filtered.
l Whether the source port ID is the same as destination port
ID.
If any of these conditions are met, the switch drops the receiving.
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.
l If it is unknown, the switch floods the receiving frame to all
ports in the VLAN, excluding the source port.
l 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.
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.
1. Introduction-8
LEARNING
Same as for unicast switching.
FILTERING
After learning the address, the switch checks:
l Whether the source port or destination port is not in the
forwarding state.
l Whether the source MAC address or destination MAC
address is to be filtered.
l Whether the source port ID is the same as destination port
ID.
If any of these conditions are met, the switch drops the receiving.
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.
1. Introduction-9
1.2.6 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.
1. Introduction-10
The following sections describe how deploying VLANs can
benefit organizations and reduce administration costs.
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.
1. Introduction-11
VLAN MEMBERSHIP
VLAN implementation allows:
l Up to 256 VLANs in one switch.
l VLANs across multiple switches by using explicit or implicit
tagging and the GARP/GVRP protocol defined in
IEEE802.1p and 802.1Q.
l An end station’s network interface card belong to multiple
VLANs.
l A switch port to 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
volumes of traffic.
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
1. Introduction-12
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 an propagate VLAN membership to all ports that belong
to the active topology of the VLAN.
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.
1. Introduction-13
1.2.7 Class-of-Service (CoS) Support
The switch provides four transmit queues on each port, with a
weighted round-robin scheme. These functions can be used to
provide independent priorities for various types of data including
real-time video, real-time voice, and best-effort data.
Priority assignment to packet-based switches is accomplished
through explicit assignment by end stations, which have
applications that require a higher priority than best-effort data.
This mechanism utilizes the IEEE802.1p and 802.1Q tag
structure, which the switch uses to decide priority assignments
for the received packets.
1.2.8 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.
1. Introduction-14
1.2.9 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” subnetworks.
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
subnetworks.
Routing switches support IP Multicast Filtering by:
l 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
l Actively sending IGMP Query messages to solicit IP Multicast
group members.
1. Introduction-15
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
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 subnetworks, an external IP multicast
router is needed if IP multicast packets have to be routed across
different subnetworks.
1.2.10 Switch Management
ADMINISTRATION CONSOLE VIA RS-232 SERIAL PORT
The switch provides an onboard serial port, which allows the
switch to be configured via a directly connected terminal or a
Telnet session.
WEB-BASED BROWSER INTERFACE
The switch also boasts a point-and-click browser-based
interface that lets users access full switch configuration and
functionality from a Netscape or Internet Explorer browser.

3. Switch Management
This chapter explains the methods that you can use to
configure management access to the switch. It describes
the types of management applications and the
communication and management protocols that deliver data
between your management device (workstation or personal
computer) and the system. It also contains information
about port connection options.
This chapter covers the following topics:
l Management Access Overview
l Key Concepts
l Key Guidelines for Implementation
l Administration Console Access
l Web Management Access
l SNMP Access
l Standards, Protocols, and Related Reading
3. Switch Management -27
3.1 Management Access Overview
The switch gives you the flexibility to access and manage the
switch using any or all of the following methods.
The administration console and web browser interface support
are embedded in the switch software and are available for
immediate use.
l Administration console via RS-232 serial port
ADVANTAGES
No IP address or subnet needed
Text-based
Telnet functionality and HyperTerminal built into Windows
95/98/NT/2000 operating systems
DISADVANTAGES
Must be near switch or use dial-up connection
Inconvenient for remote users
Modem connection may prove to be unreliable or slow
l Web-based browser interface
ADVANTAGES
Ideal for configuring the switch remotely
Compatible with all popular browsers
Can be accessed from any location
Most visually appealing
3. Switch Management -28
DISADVANTAGES
Security can be compromised
(Hackers need only know the IP address and subnet mask)
May encounter lag times on poor connections
l External SNMP-based network management application
ADVANTAGES
Communicates with switch functions at the MIB leve
Based on open standards
DISADVANTAGES
Requires SNMP manager software
Least visually appealing of all three methods
Some settings require calculations
Security can be compromised
(Hackers need only know the community name)
3. Switch Management -29
3.2 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
3. Switch Management -30
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 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, that
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.
3. Switch Management -31
3.3 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.
3.4 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.
3. Switch Management -32
3.5 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
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.
protocol in that you must connect a terminal directly to
the console port.
3. Switch Management -33
3.6 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.
3. Switch Management -34
4. 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.
For the later, you must specify an IP address for the switch first.
This chapter describes how to configure the switch using its
menu-driven console.
* For initial IP settings, you must configure the switch through its RS232 port.
