D Read the device Installation Guide for the connectivity procedure. In-band
connectivity allows access to the software locally or from a remote work-
station. The device must be configured with IP information (IP address,
subnet mask, and default gateway).
D Turn the Power on.
D Allow the device to load the software until the login prompt appears. The
device‘s initial state is called the default mode.
D When the prompt asks for operator login, execute the following steps:
D Type the word admin in the login area. Since a number of the Quick
Setup commands require administrator account rights, we recom-
mend logging into an administrator account. Press the enter key.
D Enter the state on delivery password private.
D Press the enter key
D The CLI User EXEC prompt will be displayed.
User EXEC prompt:
(Hirschmann Product) >
D Use “enable” to switch to the Privileged EXEC mode from User EXEC.

To use spaces as part of parameter name, enclose it in double quotes. For
example, the expression "System Name with Spaces" forces the system to
accept the spaces.
Parameters may be mandatory values, optional values, choices, or a combi-
nation.
D <parameter>. The <> angle brackets indicate that a mandatory param-
eter is to be entered in place of the brackets and text inside them.
D [parameter]. The [] square brackets indicate that an optional parame-
ter may be entered in place of the brackets and text inside them.
D choice1 | choice2. The | indicates that only one of the parameters
should be entered.
D The {} curly braces indicate that a parameter must be chosen from the list
of choices.
1.1.3 Values
ipaddr This parameter is a valid IP address. Pres-
ently the IP address can be entered in fol-
lowing formats:
a (32 bits)
a.b (8.24 bits)
a.b.c (8.8.16 bits)
a.b.c.d (8.8.8.8 bits)
In addition to these formats, decimal, hexa-
decimal and octal formats are supported
through the following input formats (where
n is any valid hexadecimal, octal or decimal
number):
0xn (CLI assumes hexadecimal format)

macaddr The MAC address format is six hexadeci-
mal numbers separated by colons, for
example 00:06:29:32:81:40.
areaid Area IDs may be entered in dotted-decimal
notation (for example, 0.0.0.1). An area ID
of 0.0.0.0 is reserved for the backbone.
Area IDs have the same form as IP
addresses, but are distinct from IP
addresses. The IP network address of the
sub-netted network may be used for the
area ID.
slot/port Valid slot and port number separated by
forward slashes. For example, 1/1 repre-
sents slot number 1 and port number 1.
logical slot/port Logical slot and port number. This is appli-
cable in the case of a link-aggregation
(LAG) and vlan router interfaces (9/x). The
operator can use the logical slot/port to
configure the link-aggregation.
routerid The value of <router id> must be entered in
4-digit dotted-decimal notation (for exam-
ple, 0.0.0.1). A router ID of 0.0.0.0 is
invalid.
Interface Valid slot and port number separated by
forward slashes. For example, 0/1 repre-
sents slot number 0 and port number 1.
Logical Interface Logical slot and port number. This is appli-
cable in the case of a port-channel (LAG)
and vlan router interfaces (9/x). The opera-
tor can use the logical slot/port to configure
the port-channel.
Character strings Use double quotation marks to identify
character strings, for example, “System
Name with Spaces”. An empty string (“”) is
not valid.

1.1.4 Conventions
Network addresses are used to define a link to a remote host, workstation or
network. Network addresses are shown using the following syntax:
Double quotation marks such as "System Name with Spaces" set off user de-
fined strings. If the operator wishes to use spaces as part of a name param-
eter then it must be enclosed in double quotation marks.
Empty strings (““) are not valid user defined strings.
Command completion finishes spelling the command when enough letters of
a command are typed to uniquely identify the command word. The command
may be executed by typing <enter> (command abbreviation) or the com-
mand word may be completed by typing the <tab> or <space bar> (command
completion).
The value 'Err' designates that the requested value was not internally acces-
sible.
The value of '-----' designates that the value is unknown.

1.1.5 Annotations
The CLI allows the user to type single-line annotations at the command
prompt for use when writing test or configuration scripts and for better read-
ability. The exclamation point (‘!’) character flags the beginning of a com-
ment. The comment flag character can begin a word anywhere on the
command line and all input following this character is ignored. Any command
line that begins with the character ‘!’ is recognized as a comment line and ig-
nored by the parser.

2.2 Mode-based Command
Hierarchy
The CLI is divided into various modes. The Commands in one mode are not
available until the operator switches to that particular mode, with the excep-
tion of the User Exec mode commands. The User Exec mode commands
may also be executed in the Privileged Exec mode.
The commands available to the operator at any point in time depend upon
the mode. Entering a question mark (?) at the CLI prompt, displays a list of
the available commands and descriptions of the commands.
The CLI provides the following modes:
User Exec Mode
When the operator logs into the CLI, the User Exec mode is the initial
mode. The User Exec mode contains a limited set of commands. The
command prompt shown at this level is:
Command Prompt: (Hirschmann Product)>
Privileged Exec Mode
To have access to the full suite of commands, the operator must enter
the Privileged Exec mode. Privileged users authenticated by login are
able to enter the Privileged EXEC mode. From Privileged Exec mode,
the operator can issue any Exec command, enter the Global Configu-
ration mode . The command prompt shown at this level is:
Command Prompt: (Hirschmann Product)#
Global Config Mode
This mode permits the operator to make modifications to the running
configuration. General setup commands are grouped in this mode.
From the Global Configuration mode, the operator can enter the Sys-
tem Configuration mode, the Physical Port Configuration mode, the
Interface Configuration mode, or the Protocol Specific modes speci-
fied below. The command prompt at this level is:
Command Prompt: (Hirschmann Product)(Config)#
From the Global Config mode, the operator may enter the following configu-

Interface Config Mode
Many features are enabled for a particular interface. The Interface
commands enable or modify the operation of an interface.

operation. The Interface Config mode provides access to the router
interface configuration commands. The command prompt at this level
is:

The resulting prompt for the interface configuration command entered
in the Global Configuration mode is shown below:

This mode allows the operator to configure the console interface. The
operator may configure the interface from the directly connected con-
sole. The command prompt at this level is:

2.3 Flow of Operation
This section captures the flow of operation for the CLI:
D The operator logs into the CLI session and enters the User Exec mode.
In the User Exec mode the (Hirschmann Product)(exec)> prompt is
displayed on the screen.
The parsing process is initiated whenever the operator types a command and
presses <ENTER>. The command tree is searched for the command of in-
terest. If the command is not found, the output message indicates where the
offending entry begins. For instance, command node A has the command
"show spanning-tree" but the operator attempts to execute the com-
mand
"show arpp brief" then the output message would be
(Hirschmann Product)(exec)> show sspanning-tree^.
(Hirschmann Product)%Invalid input detected at '^' mark-
er. If the operator has given an invalid input parameter in the command, then
the message conveys to the operator an invalid input was detected. The lay-
out of the output is depicted below:
(Hirschmann Product)(exec) #show sspanning-tree
^
(Hirschmann Product)Invalid input detected at '^' marker.
Fig. 2: Syntax Error Message
After all the mandatory parameters are entered, any additional parameters
entered are treated as optional parameters. If any of the parameters are not
recognized a syntax error message will be displayed.
D After the command is successfully parsed and validated, the control of
execution goes to the corresponding CLI callback function.

rameters, the command tree extends till the mandatory parameters and
the optional parameters make the leaf of the branch. However, the call
back function is associated with the node where the mandatory parame-
ters are fetched. The call back function then takes care of the optional pa-
rameters.
D Once the control has reached the callback function, the callback function
has complete information about the parameters entered by the operator.

“No” Form of a Command
33
2.4 “No” Form of a Command
“No” is a specific form of an existing command and does not represent a new
or distinct command. Only the configuration commands are available in the
“no” form. The behavior and the support details of the “no” form is captured
as part of the mapping sheets.
2.4.1 Support for “No” Form
Almost every configuration command has a “no” form. In general, use the no
form to reverse the action of a command or reset a value back to the default.
For example, the no shutdown interface configuration command re-
verses the shutdown of an interface. Use the command without the keyword
”no“ to re-enable a disabled feature or to enable a feature that is disabled by
default.
2.4.2 Behavior of Command Help ("?")
The “no” form is treated as a specific form of an existing command and does
not represent a new or distinct command. However, the behavior of the “?”
and help text differ for the “no” form (the help message shows only options
that apply to the “no” form).
D The help message is the same for all forms of the command. The help
string may be augmented with details about the “no” form behavior.
D For the (no interface?) and (no inte?) cases of the “?”, the options
displayed are identical to the case when the “no” token is not specified as
in (interface) and (inte?).

This chapter provides detailed explanation of the Switching commands. The
commands are divided into five functional groups:
D Show commands display switch settings, statistics, and other information.
D Configuration commands configure features and options of the switch.
For every configuration command, there is a show command that displays
the configuration setting.
D Copy commands transfer or save configuration and informational files to
and from the switch.
D Clear commands clear
- some
(e.g. the ”clear arp-table-switch” command which clears the agent´s
ARP table) or
- all
(e.g. the ”clear config” command which resets the whole
configuration to the factory defaults
This chapter includes the following configuration types:
D System information and statistics commands
D Management commands
D Device configuration commands
D User account management commands
D Security commands
D System utilities

SNMP Community Name
The community string to which this entry grants access. A valid entry
is a case-sensitive alphanumeric string of up to 32 characters. Each
row of this table must contain a unique community name.
Client IP Address -
An IP address (or portion thereof) from which this device will accept
SNMP packets with the associated community. The requesting
entity's IP address is ANDed with the Subnet Mask before being com-
pared to the IP Address. Note: that if the Subnet Mask is set to
0.0.0.0, an IP Address of 0.0.0.0 matches all IP addresses. The
default value is 0.0.0.0
Client IP Mask -
A mask to be ANDed with the requesting entity's IP address before
comparison with IP Address. If the result matches with IP Address
then the address is an authenticated IP address. For example, if the
IP Address = 9.47.128.0 and the corresponding Subnet Mask =
255.255.255.0 a range of incoming IP addresses would match, i.e.
the incoming IP Address could equal 9.47.128.0 - 9.47.128.255. The
default value is 0.0.0.0

the <mstid> parameter corresponds to an existing multiple spanning tree in-
stance, then the configurations are done for that multiple spanning tree in-
stance. If however 0 (defined as the default CIST ID) is passed as the
<mstid>, then the configurations are performed for the common and internal
spanning tree instance.
This command accepts the value 0 for the mstid, meaning the common and
internal spanning tree.
If the ‘cost’ token is specified, this command sets the path cost for this port
within a multiple spanning tree instance or the common and internal span-
ning tree instance, depending on the <mstid> parameter. The pathcost can
be specified as a number in the range of 1 to 200000000 or auto. If "auto" is
specified, the pathcost value will be set based on Link Speed.
If the ‘port-priority’ token is specified, this command sets the priority for this
port within a specific multiple spanning tree instance or the common and in-
ternal spanning tree instance, depending on the <mstid> parameter. The

4.2 MRP
The concept of the MRP-Ring enables the construction of high-availability,
ring-shaped network structures.
The two ends of a backbone in a line-type configuration can be closed to form
a redundant ring - the MRP-Ring - by using the RM function (Redundancy
Manager) of the Switch.
It is possible to mix the devices that support this function in any combination
within the MRP ring.
If a line section becomes inoperable, the ring structure of up to 50 switches
typically transforms back to a line-type configuration within 150 ms (maxi-
mum 500 ms).

5.1.1 authentication login
This command creates an authentication login list. The <listname> is up
to 15 alphanumeric characters and is not case sensitive. Up to 10 authenti-
cation login lists can be configured on the switch. When a list is created, the
authentication method “local” is set as the first method.
When the optional parameters “Option1”, “Option2” and/or “Option3” are
used, an ordered list of methods are set in the authentication login list. If the
authentication login list does not exist, a new authentication login list is first
created and then the authentication methods are set in the authentication
login list. The maximum number of authentication login methods is three. The
possible method values are local, radius and reject.
The value of local indicates that the user’s locally stored ID and password
are used for authentication. The value of radius indicates that the user’s ID
and password will be authenticated using the RADIUS server. The value of
reject indicates the user is never authenticated.
To authenticate a user, the authentication methods in the user’s login will be
attempted in order until an authentication attempt succeeds or fails
.
Note: The default login list included with the default configuration can not be

802.1D. The IEEE designator for
Spanning Tree Protocol (STP). STP,
a link management protocol, is part
of the 802.1D standard for media
access control bridges. Using the
spanning tree algorithm, STP
provides path redundancy while
preventing endless loops in a
network. An endless loop is created
by multiple active paths between
stations where there are alternate
routes between hosts. To establish
path redundancy, STP creates a
logical tree that spans all of the
switches in an extended network,
forcing redundant paths into a
standby, or blocked, state. STP
allows only one active path at a time
between any two network devices
(this prevents the loops) but
establishes the redundant links as a
backup if the initial link should fail. If
STP costs change, or if one network
segment in the STP becomes
unreachable, the spanning tree
algorithm reconfigures the spanning
tree topology and reestablishes the
link by activating the standby path.
Without spanning tree in place, it is
possible that both connections may
be simultaneously live, which could
result in an endless loop of traffic on
the LAN.
802.1P. The IEEE protocol
designator for Local Area Network
(LAN). This Layer 2 network
standard improves support of time
critical traffic, and limits the extent of
high bandwidth multicast traffic
within a bridged LAN. To do this,
802.1P defines a methodology for
introducing traffic class priorities.
The 802.1P standard allows priority
to be defined in all 802 MAC
protocols (Ethernet, Token Bus,
Token Ring), as well as in FDDI. For
protocols (such as Ethernet) that do
not contain a priority field, 802.1P
specifies a method for indicating
frame priority based on the new
fields defined in the 802.1Q (VLAN)
standard.
802.1Q VLAN. The IEEE protocol
designator for Virtual Local Area
Network (VLAN). This standard
provides VLAN identification and
quality of service (QoS) levels. Four
bytes are added to an Ethernet
frame to allow eight priority levels
(QoS) and to identify up to 4096
VLANs. See “VLAN” on page 266 for
more information.

Aging. When an entry for a node is
added to the lookup table of a

Bootstrap Protocol. An Internet
protocol that enables a diskless
workstation to discover its own IP
address, the IP address of a BootP
server on the network, and a file to
be loaded into memory to boot the
machine. This enables the
workstation to boot without requiring
a hard or floppy disk drive.
Bridge Protocol Data Unit. BPDU
is the IEEE 802.1D MAC Bridge
Management protocol that is the
standard implementation of STP
(Spanning Tree Protocol). It uses the
STP algorithm to insure that physical
loops in the network topology do not
result in logical looping of network
traffic. Using one bridge configured
as root for reference, the BPDU
switches one of two bridges forming
a network loop into standby mode,
so that only one side of a potential
loop passes traffic. By examing
frequent 802.1d configuration
updates, a bridge in the standby
mode can switch automatically into
the forward mode if the other bridge
forming the loop fails.
C
Checksum. A simple error-
detection scheme in which each
transmitted message is identified
with a numerical value based on the
number of set bits in the message.
The receiving station then applies a
formula to the message and checks

numerical value is the same. If not,
the receiver can assume that the
message has been corrupted.

Differentiated Services. Diffserv is
a protocol for specifying and
controlling network traffic by class so
that certain types of traffic get
precedence - for example, voice
traffic, which requires a relatively
uninterrupted flow of data, might get
precedence over other kinds of
traffic. Differentiated Services is the
most advanced method for
managing traffic in terms of what is
called Class of Service (CoS).
Unlike the earlier mechanisms of
802.1P tagging and Type of Service
(ToS), Differentiated Services avoids
simple priority tagging and depends
on more complex policy or rule
statements to determine how to
forward a given network packet. An
analogy is made to travel services,
in which a person can choose
among different modes of travel -
train, bus, airplane - degree of
comfort, the number of stops on the
route, standby status, the time of
day or period of year for the trip, and
so forth. For a given set of packet
travel rules, a packet is given one of
64 possible forwarding behaviors -
known as per hop behaviors (PHBs).
A six-bit field, known as the
Differentiated Services Code Point
(DSCP), in the Internet Protocol
(Internet Protocol) header specifies
the per hop behavior for a given flow
of packets. Differentiated Services
and the Class of Service approach
provide a way to control traffic that is
both more flexible and more
scalability than the Quality of
Service approach.
Diffserv. See “Differentiated
Services.” on page 257..
Dynamic Host Configuration
Protocol. DHCP is a protocol for
assigning dynamic IP addresses to
devices on a network. With dynamic
addressing, a device can have a
different IP address every time it
connects to the network. In some
systems, the device's IP address
can even change while it is still
connected. DHCP also supports a
mix of static and dynamic IP
addresses. Dynamic addressing
simplifies network administration
because the software tracks IP
addresses rather than requiring an
administrator to manage the task. A
new computer can be added to a
network without the hassle of
manually assigning it a unique IP
address.

Flow Control. The process of
adjusting the flow of data from one
network device to another to ensure
that the receiving device can handle
all of the incoming data. This is
particularly important where the
sending device is capable of
sending data much faster than the
receiving device can receive it.
There are many flow control
mechanisms. One of the most
common flow control protocols for
asynchronous communication is
called xon-xoff. In this case, the
receiving device sends a an “xoff”
message to the sending device
when its buffer is full. The sending
device then stops sending data.
When the receiving device is ready
to receive more data, it sends an
“xon” signal.
Forwarding. When a frame is
received on an input port on a
switch, the address is checked
against the lookup table. If the
lookup table has recorded the
destination address, the frame is
automatically forwarded on an
output port.
Frame Check Sequence. The
extra characters added to a frame
for error detection and correction.

transmissions because the server
can broadcast a message to many
recipients simultaneously. Unlike
traditional Internet traffic that
requires separate connections for
each source-destination pair, IP
Multicasting allows many recipients
to share the same source. This
means that just one set of packets is
transmitted for all the destinations.
Internet Protocol. The method or
protocol by which data is sent from
one computer to another on the
Internet. Each computer (known as
a host) on the Internet has at least
one IP address that uniquely
identifies it among all other
computers on the Internet. When
you send or receive data (for
example, an e-mail note or a Web
page), the message gets divided
into little chunks called packets.
Each of these packets contains both
the sender's Internet address and
the receiver's address. Any packet is
sent first to a gateway computer that
understands a small part of the
Internet. The gateway computer
reads the destination address and
forwards the packet to an adjacent
gateway that in turn reads the
destination address and so forth
across the Internet until one
gateway recognizes the packet as
belonging to a computer within its
immediate neighborhood or domain.
That gateway then forwards the
packet directly to the computer
whose address is specified.
Because a message is divided into a
number of packets, each packet can,
if necessary, be sent by a different
route across the Internet. Packets
can arrive in a different order than
they were sent. The Internet
Protocol just delivers them. It's up to
another protocol, the Transmission
Control Protocol (TCP) to put them
back in the right order. IP is a
connectionless protocol, which
means that there is no continuing
connection between the end points
that are communicating. Each
packet that travels through the
Internet is treated as an independent
unit of data without any relation to
any other unit of data. (The reason
the packets do get put in the right
order is because of TCP, the
connection-oriented protocol that
keeps track of the packet sequence
in a message.) In the Open Systems
Interconnection (OSI)
communication model, IP is in Layer
3, the Networking Layer. The most
widely used version of IP today is IP
version 4 (IPv4). However, IP
version 6 (IPv6) is also beginning to
be supported. IPv6 provides for
much longer addresses and
therefore for the possibility of many
more Internet users. IPv6 includes
the capabilities of IPv4 and any
server that can support IPv6 packets
can also support IPv4 packets.

Multicast Backbone. The MBONE
is a virtual network. It is layered on
top of portions of the physical
Internet to support routing of IP
multicast packets since that function
has not yet been integrated into
many production routers. The
network is composed of islands that
can directly support IP multicast,
such as multicast LANs like
Ethernet, linked by virtual point-to-
point links called "tunnels". The
tunnel endpoints are typically
workstation-class machines having
operating system support for IP
multicast and running the "mrouted"
multicast routing daemon.
Multicasting. To transmit a
message to specific recipients
across a network. A simple example
of multicasting is sending an e-mail
message to a mailing list.
Teleconferencing and
videoconferencing also use
multicasting, but require more robust
protocols and networks. Standards
are being developed to support
multicasting over a TCP/IP network
such as the Internet. These
standards, IP Multicast and Mbone,
will allow users to easily join
multicast groups. Note that
multicasting refers to sending a
message to a select group whereas
broadcasting refers to sending a
message to everyone connected to
a network. The terms multicast and
narrowcast are often used
interchangeably, although
narrowcast usually refers to the
business model whereas multicast
refers to the actual technology used
to transmit the data.
Multicast OSPF. With a MOSPF
specification, an IP Multicast packet
is routed based both on the packet's
source and its multicast destination
(commonly referred to as source/
destination routing). As it is routed,
the multicast packet follows a
shortest path to each multicast
destination. During packet
forwarding, any commonality of
paths is exploited; when multiple
hosts belong to a single multicast
group, a multicast packet will be
replicated only when the paths to the

separate hosts diverge. See “P” on

Multiplexing. A function within a

Multi-Protocol Label Switching.
An initiative that integrates Layer 2
information about network links
(bandwidth, latency, utilization) into
Layer 3 (IP) within a particular
autonomous system—or ISP—in
order to simplify and improve IP-
packet exchange. MPLS gives
network operators a great deal of
flexibility to divert and route traffic
around link failures, congestion, and
bottlenecks. From a QoS standpoint,
ISPs will better be able to manage
different kinds of data streams
based on priority and service plan.
For instance, those who subscribe to
a premium service plan, or those
who receive a lot of streaming media
or high-bandwidth content can see
minimal latency and packet loss.
When packets enter into a MPLS-
based network, Label Edge Routers
(LERs) give them a label (identifier).
These labels not only contain
information based on the routing
table entry (i.e., destination,
bandwidth, delay, and other
metrics), but also refer to the IP
header field (source IP address),
Layer 4 socket number information,
and differentiated service. Once this
classification is complete and
mapped, different packets are
assigned to corresponding Labeled
Switch Paths (LSPs), where Label
Switch Routers (LSRs) place
outgoing labels on the packets. With
these LSPs, network operators can
divert and route traffic based on
data-stream type and Internet-
access customer.

Port Mirroring. Also known as a
roving analysis port. This is a
method of monitoring network traffic
that forwards a copy of each
incoming and outgoing packet from
one port of a network switch to
another port where the packet can
be studied. A network administrator
uses port mirroring as a diagnostic
tool or debugging feature, especially
when fending off an attack. It
enables the administrator to keep
close track of switch performance
and alter it if necessary. Port
mirroring can be managed locally or
remotely. An administrator
configures port mirroring by
assigning a port from which to copy
all packets and another port where
those packets will be sent. A packet
bound for or heading away from the
first port will be forwarded onto the
second port as well. The
administrator places a protocol
analyzer on the port receiving the
mirrored data to monitor each
segment separately. The analyzer
captures and evaluates the data
without affecting the client on the
original port. The monitor port may
be a port on the same SwitchModule
with an attached RMON probe, a
port on a different SwitchModule in
the same hub, or the SwitchModule
processor. Port mirroring can
consume significant CPU resources
while active. Better choices for long-

community string-based SNMPv2. It
is an update of the protocol
operations and data types of
SNMPv2p, and uses community-
based security from SNMPv1.
SNMPv2u (experimental): This
version of the protocol uses the
protocol operations and data types
of SNMPv2c and security based on
users.
SNMPv2* (experimental): This
version combined the best features
of SNMPv2p and SNMPv2u. (It is
also called SNMPv2star.) The
documents defing this version were
never published as RFCs.
SNMPv3 (proposed): This version of
the protocol is a combination of
user-based security and the protocol
operations and data types from
SNMPv2p and support for proxies.
The security is based on that found
in SNMPv2u and SNMPv2*, and
updated after much review. The
documents defing this protocol will
soon be published as RFCs.
SimpleX signaling. SX is one of
IEEE 802.3's designations for
media. For example, 1000SX
indicates 1000 gigabit Ethernet over
"short haul" or "short wavelength"
optical fiber.

TFTP. See “Trivial File Transfer
Protocol” on page 266.
Trivial File Transfer Protocol.
TFTP is a simple form of the File
Transfer Protocol (FTP). TFTP uses
the User Datagram Protocol (UDP, a
direct protocol used to communicate
datagrams over a network with little
error recovery) and provides no
security features. It is often used by
servers to boot diskless
workstations, X-terminals, and
routers.
Trunking. The process of combing
a set of trunks that are traffic-
engineered as a unit for the
establishment of connections
between switching systems in which
all of the communications paths are
interchangeable. See “Link
Aggregation” on page 261.
V
Virtual Local Area Network.
Operating at the Data Link Layer
(Layer 2 of the OSI model), the
VLAN is a means of parsing a single
network into logical user groups or
organizations, as if they physically
resided on a dedicated LAN
segment of their own. In reality, this
virtually defined community may
have individual members peppered
across a large, extended LAN. The
VLAN identifier is part of the 802.1Q
tag, which is added to an Ethernet
frame by an 802.1Q-compliant
switch or router. Devices
recognizing 802.1Q-tagged frames
maintain appropriate tables to track
VLANs. The first three bits of the
802.1Q tag are used by 802.1P to
establish priority for the packet.

Network” on page 266.

information, based upon the
hypertext transfer protocol (HTTP).
Wide Area Network. A WAN is a
computer network that spans a
relatively large geographical area.
Typically, a WAN consists of two or
more local-area networks (LANs).
X
XModem. One of the most popular
file transfer protocols (FTPs).
Xmodem is fairly effective at
detecting errors. It sends blocks of
data together with a checksum and
then waits for acknowledgment of
the block's receipt. The waiting
slows down the rate of data
transmission considerably, but it
ensures accurate transmission.
Xmodem can be implemented either
in software or in hardware. Many
modems, and almost all
communications software packages,
support Xmodem. However, it is
useful only at relatively slow data
transmission speeds (less than
4,800 bps). Enhanced versions of
Xmodem that work at higher
transmission speeds are known as
Ymodem and Zmodem.
