Introduction
SMC’s EliteConnect Universal 2.4GHz/5GHz Wireless Access
Point (SMC2555W-AG) is an IEEE 802.11a/g access point that
provides transparent, wireless high-speed data communications
between the wired LAN and fixed, portable or mobile devices
equipped with an 802.11a, 802.11b, or 802.11g wireless adapter.
This solution offers fast, reliable wireless connectivity with
considerable cost savings over wired LANs (which include
long-term maintenance overhead for cabling). Using 802.11a,
802.11b, and 802.11g technology, this access point can easily
replace a 10 Mbps Ethernet connection or seamlessly integrate
into a 10/100 Mbps Ethernet LAN.
In addition, the access point offers full network management
capabilities through an easy to configure web interface, a
command line interface for initial configuration and
troubleshooting, and support for Simple Network Management
tools, such as SMC’s EliteView (available in Q4 of 2003).
Radio Characteristics – The IEEE 802.11a/g standard uses a
radio modulation technique known as Orthogonal Frequency
Division Multiplexing (OFDM), and a shared collision domain
(CSMA/CA). It operates at the 5 GHz Unlicensed National
Information Infrastructure (UNII) band for connections to 802.11a
clients, and at 2.4 GHz for connections to 802.11g clients.
IEEE 802.11g includes backward compatibility with the IEEE
802.11b standard. IEEE 802.11b also operates at 2.4 GHz, but
uses Direct Sequence Spread Spectrum (DSSS) modulation
technology to achieve a communication rate of up to 11 Mbps.
Introduction
1-2
The access point also supports a 54 Mbps half-duplex connection
to Ethernet networks for each active channel (up to 108 Mbps in
turbo mode on the 802.11a interface).

Component Description
Antennas
The access point includes two antennas for wireless
communications. The signal transmitted from both antennas is
identical, but only the best signal received on one of the antennas
is used. The antennas transmit the outgoing signal as a toroidal
sphere, so the antennas should be adjusted to different angles to
provide better coverage. For further information, see “Positioning
the Antennas” on page 2-2.
LED Indicators
The access point includes
four status LED indicators, as
described in the following

Ethernet Port
The access point has one 10BASE-T/100BASE-TX RJ-45 port
that can be attached directly to 10BASE-T/100BASE-TX LAN
segments. These segments must conform to the IEEE 802.3 or
802.3u specifications.
This port uses an MDI (i.e., internal straight-through) pin
configuration. You can therefore use straight-through twisted-pair
cable to connect this port to most network interconnection
devices such as a switch or router that provide MDI-X ports.
However, when connecting the access point to a workstation or
other device that does not have MDI-X ports, you must use
crossover twisted-pair cable.
The access point appears as an Ethernet node and performs a
bridging function by moving packets from the wired LAN to
remote workstations on the wireless infrastructure.
Note: The RJ-45 port also supports Power over Ethernet (PoE) based
on the IEEE 802.3af standard. Refer to the description for the
“Power Connector” for information on supplying power to the
access point’s network port from a network device, such as a
switch, that provides Power over Ethernet (PoE).
Reset Button
This button is used to reset the access point or restore the factory
default configuration. If you hold down the button for less than 5
seconds, the access point will perform a hardware reset. If you
hold down the button for 5 seconds or more, any configuration
changes you may have made are removed, and the factory
default configuration is restored to the access point.
Power Connector
The access point does not have a power switch. It is powered on
when connected to the AC power adapter, and the power adapter
is connected to a power source. The access point automatically
Features and Benefits
1-7
adjusts to any voltage between 100-240 volts at 50 or 60 Hz. No
voltage range settings are required.
The access point may also receive Power over Ethernet (PoE)
from a switch or other network device that supplies power over
the network cable based on the IEEE 802.3af standard.
Note that if the access point is connected to a PoE source device
and also connected to a local power source through the AC
power adapter, PoE will be disabled.
Features and Benefits
•Local network connection via 10/100 Mbps Ethernet ports or
54 Mbps wireless interface (supporting up to 64 mobile users)
•IEEE 802.11a, 802.11b, and 802.11g compliant
•Advanced security through 64/128/152-bit Wired Equivalent
Protection (WEP) encryption, IEEE 802.1x port
authentication, Wi-Fi Protected Access (WPA), SSID
broadcast disable, remote authentication via RADIUS server,

Hardware Installation
1. Select a Site – Choose a proper place for the access point. In
general, the best location is at the center of your wireless
coverage area, within line of sight of all wireless devices. Try
to place the access point in a position that can best cover its
Basic Service Set (refer to “Infrastructure Wireless LAN” on
page 3-3). Normally, the higher you place the access point,
the better the performance.
2. Mount the Access Point – The access point can be mounted
on any horizontal surface or wall.
Mounting on a horizontal surface – To keep the access point
from sliding on the surface, attach the four rubber feet
provided in the accessory kit to the embossed circles on the
bottom of the access point.
Mounting on a wall – The access point should be mounted
only to a wall or wood surface that is at least 1/2-inch plywood
or its equivalent. Mark the position of the mounting screws
(included) on the wall. Set the 5/8-inch number 12 wood
screws into the wall, leaving about 3 mm (0.12 in.) clearance
from the wall. And then slide the access point down onto the
screws.
3. Lock the Access Point in Place – To prevent unauthorized
removal of the access point, you can use a Kensington Slim
MicroSaver security cable (not included) to attach the access
point to a fixed object.
4. Connect the Power Cord – Connect the power adapter to
the access point, and the power cord to an AC power outlet.
Hardware Installation
2-2
Otherwise, the access point can derive its operating power
directly from the RJ-45 port when connected to a device that
provides IEEE 802.3af compliant Power over Ethernet (PoE).
Note: If the access point is connected to both a PoE source device
and an AC power source, PoE will be disabled.
Warning: Use ONLY the power adapter supplied with this access
point. Otherwise, the product may be damaged.
5. Observe the Self Test – When you power on the access
point, verify that the PWR indicator stops flashing and
remains on, and that the other indicators start functioning as
described under “LED Indicators” on page 1-4.
If the PWR LED does not stop flashing, the self test has not
completed correctly. Refer to “Troubleshooting” on page A-1.
6. Connect the Ethernet Cable – The access point can be
wired to a 10/100 Mbps Ethernet through a network device
such as a hub or a switch. Connect your network to the RJ-45
port on the back panel with category 3, 4, or 5 UTP Ethernet
cable. When the access point and the connected device are
powered on, the Ethernet Link LED should light indicating a
valid network connection.
Note: The RJ-45 port on the access point uses an MDI pin
configuration, so you must use straight-through cable for
network connections to hubs or switches that only have
MDI-X ports, and crossover cable for network connections to
PCs, servers or other end nodes that only have MDI ports.
However, if the device to which you are connecting supports
auto-MDI/MDI-X operation, you can use either
straight-through or crossover cable.
7. Position the Antennas – The antennas emit signals along a
toroidal plane, and thus provide more effective coverage
when positioned along different axes. For example, you might
position the antennas around 45 to 90 degrees from each
other.
Hardware Installation
2-3
The access point also compares the strength of an incoming
signal on both antennas, and uses the antenna receiving the
stronger signal to communicate with a wireless client.
8. Connect the Console Port – Connect the console cable
(included) to the RS-232 console port for accessing the
command-line interface. You can manage the access point
using the console port (Chapter 6), the web interface
(Chapter 5), or SNMP management software such as SMC’s
EliteView.

Network Configuration
The wireless solution supports a stand-alone wireless network
configuration as well as an integrated configuration with
10/100 Mbps Ethernet LANs.
Wireless network cards, adapters, and access points can be
configured as:
•Ad hoc for departmental, SOHO, or enterprise LANs
•Infrastructure for wireless LANs
•Infrastructure wireless LAN for roaming wireless PCs
The 802.11b and 802.11g frequency band which operates at
2.4 GHz can easily encounter interference from other 2.4 GHz
devices, such as other 802.11b or g wireless devices, cordless
phones and microwave ovens. If you experience poor wireless
LAN performance, try the following measures:
•Limit any possible sources of radio interference within the
service area
•Increase the distance between neighboring access points
•Decrease the signal strength of neighboring access points
•Increase the channel separation of neighboring access points
(e.g., up to 3 channels of separation for 802.11b, up to 4
channels for 802.11a, or up to 5 channels for 802.11g)

Network Topologies
Ad Hoc Wireless LAN (no AP or Bridge)
An ad hoc wireless LAN consists of a group of computers, each
equipped with a wireless adapter, connected via radio signals as
an independent wireless LAN. Computers in a specific ad hoc
wireless LAN must therefore be configured to the same radio
channel.

Infrastructure Wireless LAN
The access point also provides access to a wired LAN for
wireless workstations. An integrated wired/wireless LAN is called
an Infrastructure configuration. A Basic Service Set (BSS)
consists of a group of wireless PC users, and an access point
that is directly connected to the wired LAN. Each wireless PC in
this BSS can talk to any computer in its wireless group via a radio
link, or access other computers or network resources in the wired
LAN infrastructure via the access point.
The infrastructure configuration not only extends the accessibility
of wireless PCs to the wired LAN, but also increases the effective
wireless transmission range for wireless PCs by passing their
signal through one or more access points.
A wireless infrastructure can be used for access to a central
database, or for connection between mobile workers, as shown in
the following figure.

Infrastructure Wireless LAN for Roaming Wireless PCs
The Basic Service Set (BSS) is the communications domain for
each wireless access point. For wireless PCs that do not need to
support roaming, set the domain identifier (SSID) for the wireless
card to the SSID of the access point to which you want to
connect. Check with your administrator for the SSID of the access
point or bridge to which he wants you to connect.
A wireless infrastructure can also support roaming for mobile
workers. More than one access point can be configured to create
an Extended Service Set (ESS). By placing the access points so
that a continuous coverage area is created, wireless users within
this ESS can roam freely. All SMC wireless network cards and
adapters and SMC2555W-AG wireless access points within a
specific ESS must be configured with the same SSID.

Initial Configuration
The EliteConnect Universal 2.4GHz/5GHz Wireless Access
Point SMC2555W-AG offers a variety of management options,
including a web-based interface, a direct connection to the
console port, or using SNMP software such as SMC’s EliteView.
The initial configuration steps can be made through the web
browser interface using the Setup Wizard (page 4-4). The default
IP address is 192.168.2.2. If this address is not compatible with
your network, you can first use the command line interface (CLI)
as described below to configure a valid address.
Initial Setup through the CLI
Required Connections
The SMC2555W-AG provides an RS-232 serial port that enables
a connection to a PC or terminal for monitoring and configuration.
Attach a VT100-compatible terminal, or a PC running a terminal
emulation program to the access point. You can use the console
cable provided with this package, or use a null-modem cable that
complies with the wiring assignments shown on page B-4.
To connect to the console port, complete the following steps:
1. Connect the console cable to the serial port on a terminal, or
a PC running terminal emulation software, and tighten the

Setting the IP Address – By default, the access point is
configured to obtain IP address settings from a DHCP server. You
will therefore have to use the command line interface (CLI) to
assign an IP address that is compatible with your network.
Type “configure” to enter configuration mode, then type “interface
ethernet” to access the Ethernet interface-configuration mode.
First type “no dhcp” to disable DHCP client mode. Then type “ip
address ip-address netmask gateway,” where “ip-address” is the
access point’s IP address, “netmask” is the network mask for the
network, and “gateway” is the default gateway router. Check with
your system administrator to obtain an IP address that is
compatible with your network.
After configuring the access point’s IP parameters, you can
access the management interface from anywhere within the
attached network. The command line interface can also be
accessed using Telnet from any computer attached to the
network.

address resolution.
DHCP Client – With DHCP Client enabled, the IP address,
subnet mask and default gateway can be dynamically
assigned to the access point by the network DHCP server.
(Default: Disable)
Note: If there is no DHCP server on your network, then the access
point will automatically start up with its default IP address,
192.168.2.2.

System Identification
The system information parameters for the SMC2555W-AG can
be left at their default settings. However, modifying these
parameters can help you to more easily distinguish different
devices in your network.
You should set a Service Set Identification (SSID) to identify the
wireless network service provided by the SMC2555W-AG. Only
clients with the same SSID can associate with the access point.
System Name – An alias for the access point, enabling the device
to be uniquely identified on the network. (Default: Enterprise AP;
Range: 1-22 characters)
SSID – The name of the basic service set provided by the access
point. Clients that want to connect to the network through the
access point must set their SSID to the same as that of the
access point. (Default: SMC; Range: 1-32 characters)
Advanced Configuration
5-5
TCP / IP Settings
Configuring the SMC2555W-AG with an IP address expands your
ability to manage the access point. A number of access point
features depend on IP addressing to operate.
Note: You can use the web browser interface to access IP addressing
only if the access point already has an IP address that is
reachable through your network.
By default, the SMC2555W-AG will be automatically configured
with IP settings from a Dynamic Host Configuration Protocol
(DHCP) server. However, if you are not using a DHCP server to
configure IP addressing, use the CLI to manually configure the
initial IP values (page 4-2). After you have network access to the
access point, you can use the web browser interface to modify
the initial IP configuration, if needed.
Note: If there is no DHCP server on your network, or DHCP fails, the
access point will automatically start up with a default IP address of
192.168.2.2.
System Configuration
5-6
DHCP Client (Enable) – Select this option to obtain the IP
settings for the access point from a DHCP (Dynamic Host
Configuration Protocol) server. The IP address, subnet mask,
default gateway, and Domain Name Server (DNS) address are
dynamically assigned to the access point by the network DHCP
server. (Default: Disable)
DHCP Client (Disable) – Select this option to manually configure
a static address for the access point.
•IP Address: The IP address of the access point. Valid IP
addresses consist of four decimal numbers, 0 to 255,
separated by periods.
•Subnet Mask: The mask that identifies the host address bits
used for routing to specific subnets.
•Default Gateway: The default gateway is the IP address of the
router for the access point, which is used if the requested
destination address is not on the local subnet.
If you have management stations, DNS, RADIUS, or other
network servers located on another subnet, type the IP
address of the default gateway router in the text field provided.
Otherwise, leave the address as all zeros (0.0.0.0).
•Primary and Secondary DNS Address: The IP address of
Domain Name Servers on the network. A DNS maps
numerical IP addresses to domain names and can be used to
identify network hosts by familiar names instead of the IP
addresses.
If you have one or more DNS servers located on the local
network, type the IP addresses in the text fields provided.
Otherwise, leave the addresses as all zeros (0.0.0.0).
Advanced Configuration
5-7
Radius
Remote Authentication Dial-in User Service (RADIUS) is an
authentication protocol that uses software running on a central
server to control access to RADIUS-aware devices on the
network. An authentication server contains a database of user
credentials for each user that requires access to the network.
A primary RADIUS server must be specified for the
SMC2555W-AG to implement IEEE 802.1x network access
control and Wi-Fi Protected Access (WPA) wireless security. A
secondary RADIUS server may also be specified as a backup
should the primary server fail or become inaccessible.
Note: This guide assumes that you have already configured RADIUS
server(s) to support the access point. Configuration of RADIUS
server software is beyond the scope of this guide, refer to the
documentation provided with the RADIUS server software.
System Configuration
5-8
Primary Radius Server Setup – Configure the following settings
to use RADIUS authentication on the access point.
•IP Address: Specifies the IP address or host name of the
RADIUS server.
•Port: The UDP port number used by the RADIUS server for
authentication messages. (Range: 1024-65535;
Default: 1812)
•Key: A shared text string used to encrypt messages between
the access point and the RADIUS server. Be sure that the
same text string is specified on the RADIUS server. Do not
use blank spaces in the string. (Maximum length: 255
characters)
•Timeout: Number of seconds the access point waits for a reply
from the RADIUS server before resending a request.
(Range: 1-60 seconds; Default: 5)
•Retransmit attempts: The number of times the access point
tries to resend a request to the RADIUS server before
authentication fails. (Range: 1-30; Default: 3)
Note: For the Timeout and Retransmit attempts fields, accept the
default values unless you experience problems connecting to the
RADIUS server over the network.
Secondary Radius Server Setup – Configure a secondary
RADIUS server to provide a backup in case the primary server
fails. The access point uses the secondary server if the primary
server fails or becomes inaccessible. Once the access point
switches over to the secondary server, it periodically attempts to
establish communication again with primary server. If
communication with the primary server is re-established, the
secondary server reverts to a backup role.
Advanced Configuration
5-9
Authentication
Wireless clients can be authenticated for network access by
checking their MAC address against the local database
configured on the access point, or by using the IEEE 802.1x
network access authentication protocol to look up their MAC
addresses on a RADIUS server. The 802.1x protocol can also be
configured to check other user credentials such as a user name
and password.
System Configuration
5-10
MAC Authentication – You can configure a list of the MAC
addresses for wireless clients that are authorized to access the
network. This provides a basic level of authentication for wireless
clients attempting to gain access to the network. A database of
authorized MAC addresses can be stored locally on the
SMC2555W-AG or remotely on a central RADIUS server.
(Default: Local MAC)
•Local MAC: The MAC address of the associating station is
compared against the local database stored on the access
point. The Local MAC Authentication section enables the local
database to be set up.
•Radius MAC: The MAC address of the associating station is
sent to a configured RADIUS server for authentication. When
using a RADIUS authentication server for MAC address
authentication, the server must first be configured in the
Radius window (page 5-7).
•Disable: No checks are performed on an associating station’s
MAC address.
Local MAC Authentication – Configures the local MAC
authentication database. The MAC database provides a
mechanism to take certain actions based on a wireless client’s
MAC address. The MAC list can be configured to allow or deny
network access to specific clients.
•System Default: Specifies a default action for all unknown
MAC addresses (that is, those not listed in the local MAC
database).
- Deny: Blocks access for all MAC addresses except those
listed in the local database as “allowed.”
- Allow: Permits access for all MAC addresses except
those listed in the local database as “denied.”
Advanced Configuration
5-11
•MAC Authentication Settings: Enters specified MAC
addresses and permissions into the local MAC database.
- MAC Address: Physical address of a client. Enter six pairs
of hexadecimal digits separated by hyphens; for example,
00-90-D1-12-AB-89.
- Permission: Select Allow to permit access or Deny to
block access. If Delete is selected, the specified MAC
address entry is removed from the database.
- Update: Enters the specified MAC address and
permission setting into the local database.
•MAC Authentication Table: Displays current entries in the local
MAC database.
802.1x Setup – IEEE 802.1x is a standard framework for network
access control that uses a central RADIUS server for user
authentication. This control feature prevents unauthorized access
to the network by requiring an 802.1x client application to submit
user credentials for authentication. The 802.1x standard uses the
Extensible Authentication Protocol (EAP) to pass user credentials
(either digital certificates, user names and passwords, or other)
from the client to the RADIUS server. Client authentication is then
verified on the RADIUS server before the access point grants
client access to the network.
The 802.1x EAP packets are also used to pass dynamic unicast
session keys and static broadcast keys to wireless clients.
Session keys are unique to each client and are used to encrypt
and correlate traffic passing between a specific client and the
access point. You can also enable broadcast key rotation, so the
access point provides a dynamic broadcast key and changes it at
a specified interval.
You can enable 802.1x as optionally supported or as required to
enhance the security of the wireless network.
•Disable: The access point does not support 802.1x
authentication for any wireless client. After successful
System Configuration
5-12
wireless association with the access point, each client is
allowed to access the network.
•Supported: The access point supports 802.1x authentication
only for clients initiating the 802.1x authentication process (the
access point does not initiate 802.1x authentication). For
clients initiating 802.1x, only those successfully authenticated
are allowed to access the network. For those clients not
initiating 802.1x, access to the network is allowed after
successful wireless association with the access point.
•Required: The access point enforces 802.1x authentication for
all associated wireless clients. If 802.1x authentication is not
initiated by a client, the access point will initiate authentication.
Only those clients successfully authenticated with 802.1x are
allowed to access the network.
When 802.1x is enabled, the broadcast and session key rotation
intervals can also be configured.
•Broadcast Key Refresh Rate: Sets the interval at which the
broadcast keys are refreshed for stations using 802.1x
dynamic keying. (Range: 0-1440 minutes; Default: 0 means
disabled)
•Session Key Refresh Rate: The interval at which the access
point refreshes unicast session keys for associated clients.
(Range: 0-1440 minutes; Default: 0 means disabled)
•802.1x Re-authentication Refresh Rate: The time period after
which a connected client must be re-authenticated. During the
re-authentication process of verifying the client’s credentials
on the RADIUS server, the client remains connected the
network. Only if re-authentication fails is network access
blocked. (Range: 0-65535 seconds; Default: 0 means
disabled)
Advanced Configuration
5-13
Filter Control
The access point can employ VLAN ID and network traffic frame
filtering to control access to network resources and increase
security.
System Configuration
5-14
Native VLAN ID – The VLAN ID assigned to wireless clients that
are not assigned to a specific VLAN by RADIUS server
configuration.
VLAN – Enables or disables VLAN tagging support on the
SMC2555W-AG. If enabled, the access point will tag traffic
passing from wireless clients to the wired network with the VLAN
ID associated with each client on the RADIUS server. Up to 64
VLAN IDs can be mapped to specific wireless clients, allowing
users to remain within the same VLAN as they move around a
campus site. This feature can also be used to control access to
network resources from wireless clients, thereby improving
security.
A VLAN ID (1-4095) is assigned to a client after successful
authentication using IEEE 802.1x and a central RADIUS server.
The user VLAN IDs must be configured on the RADIUS server for
each user authorized to access the network. If a user does not
have a configured VLAN ID, the access point assigns the user to
its own configured native VLAN ID.
When setting up VLAN IDs for each user on the RADIUS server,
be sure to use the RADIUS attributes and values as indicated in
the following table.
Note: The specific configuration of RADIUS server software is beyond
the scope of this guide. Refer to the documentation provided with
the RADIUS server software.
Number RADIUS Attribute Value
64 Tunnel-Type VLAN (13)
65 Tunnel-Medium-Type 802
81 Tunnel-Private-Group VLANID
(1 to 4095 in
hexadecimal)
Advanced Configuration
5-15
When VLAN filtering is enabled, the access point must also have
802.1x authentication enabled and a RADIUS server configured.
Wireless clients must also support 802.1x client software to be
assigned to a specific VLAN.
When VLAN filtering is disabled, the access point ignores the
VLAN tags on any received frames.
Local Bridge Filter – Controls wireless-to-wireless
communications between clients through the SMC2555W-AG.
However, it does not affect communications between wireless
clients and the wired network.
•Disable: Allows wireless-to-wireless communications between
clients through the access point.
•Enable: Blocks wireless-to-wireless communications between
clients through the access point.
AP Management Filter – Controls management access to the
SMC2555W-AG from wireless clients. Management interfaces
include the web, Telnet, or SNMP.
•Disable: Allows management access from wireless clients.
•Enable: Blocks management access from wireless clients.
Ethernet Type Filter – Controls checks on the Ethernet type of all
incoming and outgoing Ethernet packets against the protocol
filtering table.
•Disable: Access point does not filter Ethernet protocol types.
•Enable: Access point filters Ethernet protocol types based on
the configuration of protocol types in the filter table. If a
protocol has its status set to “ON,” the protocol is filtered from
the access point.
System Configuration
5-16
SNMP
You can use a network management application such as SMC’s
EliteView (EliteView v6.11, available in Q4 of 2003) to manage
the SMC2555W-AG via the Simple Network Management
Protocol (SNMP) from a network management station. To
implement SNMP management, the SMC2555W-AG must have
an IP address and subnet mask, configured either manually or
dynamically. Once an IP address has been configured,
appropriate SNMP communities and trap receivers should be
configured.
Community names are used to control management access to
SNMP stations, as well as to authorize SNMP stations to receive
trap messages from the access point. To communicate with the
access point, a management station must first submit a valid
community name for authentication. You therefore need to assign
community names to specified users or user groups and set the
access level.
Advanced Configuration
5-17
SNMP – Enables or disables SNMP management access and
also enables the access point to send SNMP traps (notifications).
SNMP management is enabled by default.
Location – A text string that describes the system location.
(Maximum length: 20 characters)
Contact – A text string that describes the system contact.
(Maximum length: 255 characters)
Community Name (Read Only) – Defines the SNMP community
access string that has read-only access. Authorized management
stations are only able to retrieve MIB objects. (Maximum length:
23 characters, case sensitive)
Community Name (Read/Write) – Defines the SNMP community
access string that has read/write access. Authorized
management stations are able to both retrieve and modify MIB
objects. (Maximum length: 23 characters, case sensitive)
Trap Destination IP Address – Specifies the recipient of SNMP
notifications. Enter the IP address or the host name. (Host Name:
1 to 20 characters)
Trap Destination Community Name – The community string sent
with the notification operation. (Maximum length: 23 characters)
System Configuration
5-18
Administration
Changing the Password
Management access to the web and CLI interface on the
SMC2555W-AG is controlled through a single user name and
password. You can also gain additional access security by using
control filters (see “Filter Control” on page 5-13).
To protect access to the management interface, you need to
configure an Administrator’s user name and password as soon as
possible. If the user name and password are not configured, then
anyone having access to the access point may be able to
compromise access point and network security.
Note: Pressing the Reset button on the back of the SMC2555W-AG for
more than five seconds resets the user name and password to the
factory defaults. For this reason, we recommend that you protect
the access point from physical access by unauthorized persons.
Username – The name of the user. The default name is “admin.”
(Length: 3-16 characters, case sensitive.)
New Password – The password for management access.
(Length: 3-16 characters, case sensitive)
Confirm New Password – Enter the password again for
verification.

Upgrading Firmware
You can upgrade new SMC2555W-AG software from a local file
on the management workstation, or from an FTP or TFTP server.
New software may be provided periodically on SMC’s web site
(http://www.smc.com).
After upgrading new software, you must reboot the
SMC2555W-AG to implement the new code. Until a reboot
occurs, the SMC2555W-AG will continue to run the software it
was using before the upgrade started. Also note that rebooting
the access point with new software will reset the configuration to
the factory default settings.
System Configuration
5-20
Before upgrading new software, verify that the SMC2555W-AG is
connected to the network and has been configured with a
compatible IP address and subnet mask.
If you need to download from an FTP or TFTP server, take the
following additional steps:
•Obtain the IP address of the FTP or TFTP server where the
access point software is stored.
•If upgrading from an FTP server, be sure that you have an
account configured on the server with a user name and
password.
•If VLANs are configured on the access point, determine the
VLAN ID with which the FTP or TFTP server is associated,
and then configure the management station with the same
VLAN ID. If you are managing the access point from a wireless
client, the VLAN ID for the the wireless client must be
configured on a RADIUS server.
Current version – Version number of runtime code.

System Log
The SMC2555W-AG can be configured to send event and error
messages to a System Log Server. The system clock can also be
synchronized with a time server, so that all the messages sent to
the Syslog server are stamped with the correct time and date.
Enabling System Logging
The SMC2555W-AG supports a logging process that can control
error messages saved to memory or sent to a Syslog server. The
logged messages serve as a valuable tool for isolating access
point and network problems.
System Log Setup – Enables the logging of error messages.
Logging Host – Enables the sending of log messages to a Syslog
server host.
Advanced Configuration
5-23
Server Name/IP – The IP address or name of a Syslog server.
Logging Console – Enables the logging of error messages to the
console.
Logging Level – Sets the minimum severity level for event
logging.
The system allows you to limit the messages that are logged by
specifying a minimum severity level. The following table lists the
error message levels from the most severe (Alert) to least severe
(Debug). The message levels that are logged include the
specified minimum level up to the Alert level.
Note: The access point error log can be viewed using the Event Logs
window in the Status section (page 5-44).The Event Logs window
displays the last 128 messages logged in chronological order,
from the newest to the oldest. Log messages saved in the access
point’s memory are erased when the device is rebooted.
Configuring SNTP
Simple Network Time Protocol (SNTP) allows the
SMC2555W-AG to set its internal clock based on periodic
updates from a time server (SNTP or NTP). Maintaining an
accurate time on the access point enables the system log to
record meaningful dates and times for event entries. If the clock is
Error Level Description

System Configuration
5-24
not set, the access point will only record the time from the factory
default set at the last bootup.
The SMC2555W-AG acts as an SNTP client, periodically sending
time synchronization requests to specific time servers. You can
configure up to two time server IP addresses. The access point
will attempt to poll each server in the configured sequence.
SNTP Server – Configures the access point to operate as an
SNTP client. When enabled, at least one time server IP address
must be specified.
•Primary Server: The IP address of an SNTP or NTP time
server that the access point attempts to poll for a time update.
•Secondary Server: The IP address of a secondary SNTP or
NTP time server. The access point first attempts to update the
time from the primary server; if this fails it attempts an update
from the secondary server.
Note: The SMC2555W-AG also allows you to disable SNTP and set the
system clock manually using the CLI.
Set Time Zone – SNTP uses Coordinated Universal Time (or
UTC, formerly Greenwich Mean Time, or GMT) based on the time
at the Earth’s prime meridian, zero degrees longitude. To display
a time corresponding to your local time, you must indicate the
number of hours your time zone is located before (east) or after
(west) UTC.
Enable Daylight Saving – The access point provides a way to
automatically adjust the system clock for Daylight Savings Time
changes. To use this feature you must define the month and date
to begin and to end the change from standard time. During this
period the system clock is set back by one hour.
Radio Interface
5-25
Radio Interface
The IEEE 802.11a and 802.11g interfaces include configuration
options for radio signal characteristics and wireless security
features. The configuration options are nearly identical, and are
therefore both covered in this section of the manual.
The access point can operate in three modes, IEEE 802.11a only,
802.11b/g only, or a mixed 802.11a/b/g mode. Also note that
802.11g is backward compatible with 802.11b. These interfaces
are configured independently under the following web pages:
•Radio Interface 1: 802.11a
•Radio Interface 2: 802.11b/g
Note: The radio channel settings for the SMC2555W-AG are limited by
local regulations, which determine the number of channels that
are available.
System Configuration
5-26
Radio Settings (802.11a)
The IEEE 802.11a interface operates within the 5 GHz band, at
up to 54 Mbps in normal mode or up to 108 Mbps in Turbo mode.
Enable – Enables radio communications on the SMC2555W-AG.
(Default: Enabled)
Turbo Mode – The normal 802.11a wireless operation mode
provides connections up to 54 Mbps. Turbo Mode is an enhanced
mode (not regulated in IEEE 802.11a) that provides a higher data
rate of up to 108 Mbps. Enabling Turbo Mode allows the
SMC2555W-AG to provide connections up to 108 Mbps.
(Default: Disabled)
Radio Interface
5-27
Note: In normal mode, the access point provides a channel bandwidth
of 20 MHz, and supports the maximum number of channels
permitted by local regulations (e.g., 11 channels for the United
States). In Turbo Mode, the channel bandwidth is increased to 40
MHz to support the increased data rate. However, this reduces
the number of channels supported (e.g., 5 channels for the United
States).
Radio Channel – The radio channel that the
access point uses to communicate with
wireless clients. When multiple access points
are deployed in the same area, set the channel
on neighboring access points at least four
channels apart to avoid interference with each
other. For example, in the United States you
can deploy up to four access points in the
same area (e.g., channels 36, 56, 149, 165).
Also note that the channel for wireless clients
is automatically set to the same as that used by
the access point to which it is linked. (Default:
Channel 60 for normal mode, and channel 42
for Turbo mode)
Auto Channel Select – Enables the access
point to automatically select an unoccupied
radio channel. (Default: Enabled)
Transmit Power – Adjusts the power of the radio signals
transmitted from the access point. The higher the transmission
power, the farther the transmission range. Power selection is not
just a trade off between coverage area and maximum supported
clients. You also have to ensure that high-power signals do not
interfere with the operation of other radio devices in the service
area. (Options: 100%, 50%, 25%, 12%, minimum; Default: 100%)

5-28
Maximum Supported Rate – The maximum data rate at which a
client can connect to the access point. The maximum
transmission distance is affected by the data rate. The lower the
data rate, the longer the transmission distance.
(Options: 54, 48, 36, 24 Mbps; Default: 54 Mbps)
Beacon Interval – The rate at which beacon signals are
transmitted from the access point. The beacon signals allow
wireless clients to maintain contact with the access point. They
may also carry power-management information.
(Range: 20-1000 TUs; Default: 100 TUs)
Data Beacon Rate – The rate at which stations in sleep mode
must wake up to receive broadcast/multicast transmissions.
Known also as the Delivery Traffic Indication Map (DTIM) interval,
it indicates how often the MAC layer forwards broadcast/multicast
traffic, which is necessary to wake up stations that are using
Power Save mode. The default value of 2 indicates that the
access point will save all broadcast/multicast frames for the Basic
Service Set (BSS) and forward them after every second beacon.
Using smaller DTIM intervals delivers broadcast/multicast frames
in a more timely manner, causing stations in Power Save mode to
wake up more often and drain power faster. Using higher DTIM
values reduces the power used by stations in Power Save mode,
but delays the transmission of broadcast/multicast frames.
(Range: 1-255 beacons; Default: 2 beacons)
RTS Threshold – Sets the packet size threshold at which a
Request to Send (RTS) signal must be sent to a receiving station
prior to the sending station starting communications. The access
point sends RTS frames to a receiving station to negotiate the
sending of a data frame. After receiving an RTS frame, the station
sends a CTS (clear to send) frame to notify the sending station
that it can start sending data.
Radio Interface
5-29
If the RTS threshold is set to 0, the access point never sends RTS
signals. If set to 2347, the access point always sends RTS
signals. If set to any other value, and the packet size equals or
exceeds the RTS threshold, the RTS/CTS (Request to Send /
Clear to Send) mechanism will be enabled.
The access points contending for the medium may not be aware
of each other. The RTS/CTS mechanism can solve this “Hidden
Node Problem.” (Range: 0-2347 bytes: Default: 2347 bytes)
Radio Settings (802.11g)
The IEEE 802.11g standard operates within the 2.4 GHz band at
up to 54 Mbps. Also note that because the IEEE 802.11g
standard is an extension of the IEEE 802.11b standard, it allows
clients with 802.11b wireless network cards to associate to an
802.11g access point.
System Configuration
5-30
Enable – Enables radio communications on the SMC2555W-AG.
(Default: Enabled)
Radio Channel – The radio channel that the access point uses to
communicate with wireless clients. When multiple access points
are deployed in the same area, set the channel on neighboring
access points at least five channels apart to avoid interference
with each other. For example, in the United States you can deploy
up to three access points in the same area (e.g., channels 1, 6,
11). Also note that the channel for wireless clients is automatically
set to the same as that used by the access point to which it is
linked. (Range: 1-11; Default: 1)
Auto Channel Select – Enables the access point to automatically
select an unoccupied radio channel. (Default: Enabled)
Maximum Supported Rate – The maximum data rate at
which a client can connect to the access point. The
maximum transmission distance is affected by the data
rate. The lower the data rate, the longer the transmission
distance. (Default: 54 Mbps)
For a description of the remaining configuration items, see
“Radio Settings (802.11a)” on page 5-26.

Security
The SMC2555W-AG is configured by default as an “open
system,” which broadcasts a beacon signal including the
configured SSID. Wireless clients can read the SSID from the
beacon, and automatically reset their SSID to allow immediate
connection to the nearest access point.
To improve wireless network security, you have to implement two
main functions:
•Authentication: It must be verified that clients attempting to
connect to the network are authorized users.
•Traffic Encryption: Data passing between the access point and
clients must be protected from interception and evesdropping.
For a more secure network, the access point can implement one
or a combination of the following security mechanisms:
•Wired Equivalent Privacy (WEP) page 5-33
•IEEE 802.1x page 5-11
•Wireless MAC address filtering page 5-10
•Wi-Fi Protected Access (WPA) page 5-36
System Configuration
5-32
The security mechanisms that may be employed depend on the
level of security required, the network and management
resources available, and the software support provided on
wireless clients. A summary of wireless security considerations is
listed in the following table.

Wired Equivalent Privacy (WEP)
WEP provides a basic level of security, preventing unauthorized
access to the network and encrypting data transmitted between
wireless clients and the access point. WEP uses static shared
keys (fixed-length hexadecimal or alphanumeric strings) that are
manually distributed to all clients that want to use the network.
WEP is the security protocol initially specified in the IEEE 802.11
standard for wireless communications. Unfortunately, WEP has
been found to be seriously flawed and cannot be recommended
for a high level of network security. For more robust wireless
security, the SMC2555W-AG provides Wi-Fi Protected Access
(WPA) for improved data encryption and user authentication.
System Configuration
5-34
Setting up shared keys enables the basic IEEE 802.11 Wired
Equivalent Privacy (WEP) on the access point to prevent
unauthorized access to the network.
If you choose to use WEP shared keys instead of an open
system, be sure to define at least one static WEP key for user
authentication and data encryption. Also, be sure that the WEP
shared keys are the same for each client in the wireless network.
Authentication Type Setup – Sets the access point to
communicate as an open system that accepts network access
attempts from any client, or with clients using pre-configured
static shared keys.
•Open System: Select this option if you plan to use WPA or
802.1x as a security mechanism. If you don’t set up any other
security mechanism on the access point, the network has no
protection and is open to all users. This is the default setting.
•Shared Key: Sets the access point to use WEP shared keys.
If this option is selected, you must configure at least one key
on the access point and all clients.
Wired Equivalent Privacy (WEP) Setup – Enable or disable the
access point to use WEP shared keys for data encryption. If this
option is selected, you must configure at
least one key on the
access point and all clients. (Default: Disable)
Shared Key Setup – Select 64 Bit, 128 Bit, or 152 Bit key length.
Note that the same size of encryption key must be supported on
all wireless clients. (Default: 128 Bit)
Radio Interface
5-35
Key Type – Select the preferred method of entering WEP
encryption keys on the access point and enter up to four keys:
•Hexadecimal: Enter keys as 10 hexadecimal digits (0 to 9 and
A to F) for 64 bit keys, 26 hexadecimal digits for 128 bit keys,
or 32 hexadecimal digits for 152 bit keys.
•Alphanumeric: Enter keys as 5 alphanumeric characters for 64
bit keys, 13 alphanumeric characters for 128 bit keys, or 16
alphanumeric characters for 152 bit keys.
•Transmit Key Select: Selects the key number to use for
encryption. If the clients have all four keys configured to the
same values, you can change the encryption key to any of the
four settings without having to update the client keys.
System Configuration
5-36
Wi-Fi Protected Access (WPA)
WPA employs a combination of several technologies to provide
an enhanced security solution for 802.11 wireless networks.
The SMC2555W-AG supports the following WPA components
and features:
IEEE 802.1x and the Extensible Authentication Protocol
(EAP):
WPA employs 802.1x as its basic framework for user
authentication and dynamic key management. The 802.1x client
and RADIUS server should use an appropriate EAP type—such
as EAP-TLS (Transport Layer Security), EAP-TTLS (Tunneled
TLS), or PEAP (Protected EAP)—for strongest authentication.
Working together, these protocols provide “mutual authentication”
between a client, the access point, and a RADIUS server that
prevents users from accidentally joining a rogue network. Only
when a RADIUS server has authenticated a user’s credentials will
encryption keys be sent to the access point and client.
Radio Interface
5-37
Note: To implement WPA on wireless clients requires a WPA-enabled
network card driver and 802.1x client software that supports the
EAP authentication type that you want to use. Windows XP
provides native WPA support, other systems require additional
software.
Temporal Key Integrity Protocol (TKIP): WPA specifies TKIP as
the data encryption method to replace WEP. TKIP avoids the
problems of WEP static keys by dynamically changing data
encryption keys. Basically, TKIP starts with a master (temporal)
key for each user session and then mathematically generates
other keys to encrypt each data packet. TKIP provides further
data encryption enhancements by including a message integrity
check for each packet and a re-keying mechanism, which
periodically changes the master key.
WPA Pre-Shared Key (PSK) Mode: For enterprise deployment,
WPA requires a RADIUS authentication server to be configured
on the wired network. However, for small office networks that may
not have the resources to configure and maintain a RADIUS
server, WPA provides a simple operating mode that uses just a
pre-shared password for network access. The Pre-Shared Key
mode uses a common password for user authentication that is
manually entered on the access point and all wireless clients. The
PSK mode uses the same TKIP packet encryption and key
management as WPA in the enterprise, providing a robust and
manageable alternative for small networks.
Mixed WPA and WEP Client Support: WPA enables the access
point to indicate its supported encryption and authentication
mechanisms to clients using its beacon signal. WPA-compatible
clients can likewise respond to indicate their WPA support. This
enables the access point to determine which clients are using
WPA security and which are using legacy WEP. The access point
uses TKIP unicast data encryption keys for WPA clients and WEP
unicast keys for WEP clients. The global encryption key for
System Configuration
5-38
multicast and broadcast traffic must be the same for all clients,
therefore it restricts encryption to a WEP key.
Advanced Encryption Standard (AES) Support: WPA specifies
AES encryption as an optional alternative to TKIP and WEP. AES
provides very strong encryption using a completely different
ciphering algorithm to TKIP and WEP. The developing IEEE
802.11i wireless security standard has specified AES as an
eventual replacement for TKIP and WEP. However, because of
the difference in ciphering algorithms, AES requires new
hardware support in client network cards that is currently not
widely available. The access point includes AES support as a
future security enhancement.
The WPA configuration parameters are described below:
WPA Configuration Mode – The access point can be configured
to allow only WPA-enabled clients to access the network, or also
allow clients only capable of supporting WEP.
WPA Key Management – WPA can be configured to work in an
enterprise environment using IEEE 802.1x and a RADIUS server
for user authentication. For smaller networks, WPA can be
enabled using a common pre-shared key for client authentication
with the access point.
•WPA authentication over 802.1x: The WPA enterprise mode
that uses IEEE 802.1x to authenticate users and to
dynamically distribute encryption keys to clients.
•WPA Pre-shared Key: The WPA mode for small networks that
uses a common password string that is manually distributed.
If this mode is selected, be sure to also specify the key string.
Radio Interface
5-39
Multicast Cipher Mode – Selects an encryption method for the
global key used for multicast and broadcast traffic, which is
supported by all wireless clients.
•WEP: WEP is the first generation security protocol used to
encrypt data crossing the wireless medium using a fairly short
key. Communicating devices must use the same WEP key to
encrypt and decrypt radio signals. WEP has many security
flaws, and is not recommended for transmitting
highly-sensitive data.
•TKIP: TKIP provides data encryption enhancements including
per-packet key hashing (that is, changing the encryption key
on each packet), a message integrity check, an extended
initialization vector with sequencing rules, and a re-keying
mechanism.
•AES: AES has been designated by the National Institute of
Standards and Technology as the successor to the Data
Encryption Standard (DES) encryption algorithm, and will be
used by the U.S. government for encrypting all sensitive,
nonclassified information. Because of its strength, and
resistance to attack, AES is also being incorporated as part of
the 802.11 standard.
WPA Pre-Shared Key Type – If the WPA pre-shared-key mode is
used, all wireless clients must be configured with the same key to
communicate with the access point.
•Hexadecimal: Enter a key as a string of 64 hexadecimal
numbers.
•Alphanumeric: Enter a key as an easy-to-remember form of
letters and numbers. The string must be from 8 to 63
characters, which can include spaces.

Command Line Interface
Using the Command Line Interface
Accessing the CLI
When accessing the management interface for the
SMC2555W-AG over a direct connection to the console port, or
via a Telnet connection, the access point can be managed by
entering command keywords and parameters at the prompt.
Using the access point’s command-line interface (CLI) is very
similar to entering commands on a UNIX system.
Console Connection
To access the access point through the console port, perform
these steps:
1. At the console prompt, enter the user name and password.
(The default user name is “smcadmin” and the default
password is “admin.”) When the user name is entered, the CLI
displays the “SMC Enterprise AP#” prompt.
2. Enter the necessary commands to complete your desired
tasks.
3. When finished, exit the session with the “exit” command.
Command Line Interface
6-2
After connecting to the system through the console port, the login
screen displays:
Note: Command examples shown later in this chapter abbreviate the
console prompt to “SMC-AP” for simplicity.
Telnet Connection
Telnet operates over the IP transport protocol. In this
environment, your management station and any network device
you want to manage over the network must have a valid IP
address. Valid IP addresses consist of four numbers, 0 to 255,
separated by periods. Each address consists of a network portion
and host portion. For example, if the access point cannot acquire
an IP address from a DHCP server, the default IP address used
by the access point, 192.168.1.1, consists of a network portion
(192.168.1) and a host portion (1).
To access the access point through a Telnet session, you must
first set the IP address for the access point, and set the default
gateway if you are managing the access point from a different IP
subnet. For example:
If your corporate network is connected to another network outside
your office or to the Internet, you need to apply for a registered IP
address. However, if you are attached to an isolated network,
then you can use any IP address that matches the network
segment to which you are attached.

After you configure the access point with an IP address, you can
open a Telnet session by performing these steps.
1. From the remote host, enter the Telnet command and the IP
address of the device you want to access.
2. At the prompt, enter the user name and system password.
The CLI will display the “SMC Enterprise AP#” prompt to
show that you are using executive access mode (i.e., Exec).
3. Enter the necessary commands to complete your desired
tasks.
4. When finished, exit the session with the “quit” or “exit”
command.
After entering the Telnet command, the login screen displays:
Note: You can open up to four sessions to the device via Telnet.
Entering Commands
This section describes how to enter CLI commands.
Keywords and Arguments
A CLI command is a series of keywords and arguments.
Keywords identify a command, and arguments specify
configuration parameters. For example, in the command “show
interfaces ethernet,” show and interfaces are keywords, and
ethernet is an argument that specifies the interface type.

You can enter commands as follows:
•To enter a simple command, enter the command keyword.
•To enter commands that require parameters, enter the
required parameters after the command keyword. For
example, to set a password for the administrator, enter:
SMC Enterprise AP(config)#username smith
Minimum Abbreviation
The CLI will accept a minimum number of characters that
uniquely identify a command. For example, the command
“configure” can be entered as con. If an entry is ambiguous, the
system will prompt for further input.
Command Completion
If you terminate input with a Tab key, the CLI will print the
remaining characters of a partial keyword up to the point of
ambiguity. In the “configure” example, typing con followed by a
tab will result in printing the command up to “configure.”
Getting Help on Commands
You can display a brief description of the help system by entering
the help command. You can also display command syntax by
following a command with the “?” character to list keywords or
parameters.
Showing Commands
If you enter a “?” at the command prompt, the system will display
the first level of keywords for the current configuration mode
(Exec, Global Configuration, or Interface). You can also display a

Negating the Effect of Commands
For many configuration commands you can enter the prefix
keyword “no” to cancel the effect of a command or reset the
configuration to the default value. For example, the logging
command will log system messages to a host server. To disable
logging, specify the no logging command. This guide describes
the negation effect for all applicable commands.
Using Command History
The CLI maintains a history of commands that have been
entered. You can scroll back through the history of commands by
pressing the up arrow key. Any command displayed in the history
list can be executed again, or first modified and then executed.
Using the show history command displays a longer list of
recently executed commands.
Understanding Command Modes
The command set is divided into Exec and Configuration classes.
Exec commands generally display information on system status
or clear statistical counters. Configuration commands, on the
other hand, modify interface parameters or enable certain
functions. These classes are further divided into different modes.
Available commands depend on the selected mode. You can
always enter a question mark “?” at the prompt to display a list of
the commands available for the current mode. The command
classes and associated modes are displayed in the following
table:
Class Mode
Exec Privileged
Configuration Global
Interface-ethernet
Interface-wireless
Entering Commands
6-7
Exec Commands
When you open a new console session on access point, the
system enters Exec command mode. Only a limited number of
the commands are available in this mode. You can access all
other commands only from the configuration mode. To access
Exec mode, open a new console session with the user name
“admin.” The command prompt displays as “SMC Enterprise AP#”
for Exec mode.
Configuration Commands
Configuration commands are used to modify access point
settings. These commands modify the running configuration and
are saved in memory.
The configuration commands are organized into three different
modes:
•Global Configuration - These commands modify the system
level configuration, and include commands such as
username and password.
•Interface-Ethernet Configuration - These commands modify
the Ethernet port configuration, and include command such as
dns and ip.
•Interface-Wireless Configuration - These commands modify
the wireless port configuration, and include command such as
ssid and authentication.
Username: admin
Password: [system login password]
SMC-AP#
Command Line Interface
6-8
To enter the Global Configuration mode, enter the command
configure in Exec mode. The system prompt will change to
“SMC Enterprise AP(config)#” which gives you access privilege
to all Global Configuration commands.
To enter Interface mode, you must enter the “interface ethernet,”
or “interface wireless a,” or “interface wireless g” command
while in Global Configuration mode. The system prompt will
change to “SMC Enterprise AP(if-ethernet)#,” or SMC Enterprise
AP(if-wireless)” indicating that you have access privileges to the
associated commands. You can use the end command to return
to the Exec mode.
Command Line Processing
Commands are not case sensitive. You can abbreviate
commands and parameters as long as they contain enough
letters to differentiate them from any other currently available
commands or parameters. You can use the Tab key to complete
partial commands, or enter a partial command followed by the “?”
character to display a list of possible matches. You can also use
the following editing keystrokes for command-line processing:
SMC-AP#configure
SMC-AP(config)#
SMC-AP(config)#interface ethernet
SMC-AP(if-ethernet)#

802.1x Port Authentication
6-47
802.1x Port Authentication
The access point supports IEEE 802.1x access control for
wireless clients. This control feature prevents unauthorized
access to the network by requiring a 802.1x client application to
submit a user name and password for authentication. Client
authentication is then verified via by a RADIUS server using
EAPOL (Extensible Authentication Protocol Over LAN) before the
access point grants client access to the network.

authentication process (i.e., the access point does NOT
initiate 802.1x authentication). For stations initiating 802.1x,
only those stations successfully authenticated are allowed
to access the network. For those stations not initiating
802.1x, access to the network is allowed after successful
802.11 association.
• When 802.1x is required, the access point enforces 802.1x
authentication for all 802.11 associated stations. If 802.1x
authentication is not initiated by the station, the access point
will initiate authentication. Only those stations successfully
authenticated with 802.1x are allowed to access the
network.
• 802.1x does not apply to the 10/100Base-TX port.
Example
802.1x broadcast-key-refresh-rate
This command sets the interval at which the broadcast keys are
refreshed for stations using 802.1x dynamic keying.
Syntax

Command Usage
• The access point uses EAPOL (Extensible Authentication
Protocol Over LANs) packets to pass dynamic unicast
session and broadcast keys to wireless clients. The 802.1x
broadcast-key-refresh-rate command specifies the
interval after which the broadcast keys are changed. The
802.1x session-key-refresh-rate command specifies the
interval after which unicast session keys are changed.
• Dynamic broadcast key rotation allows the access point to
generate a random group key and periodically update all
key-management capable wireless clients.
Example
802.1x session-key-refresh-rate
This command sets the interval at which unicast session keys are
refreshed for associated stations using dynamic keying.

are available.
• When multiple access points are deployed in the same area,
be sure to choose a channel separated by at least four
channels for 802.11a to avoid having the channels interfere
with each other, and at least five channels for 802.11g. You
can deploy up to four access points in the same area for
802.11a (e.g., channels 36, 56, 149, 165) and three access
points for 802.11g (e.g., channels 1, 6, 11).
• For most wireless adapters, the channel for wireless clients
is automatically set to the same as that used by the access
point to which it is linked.

• The normal 802.11a wireless operation mode provides
connections up to 54 Mbps. Turbo Mode is an enhanced
mode (not regulated in IEEE 802.11a) that provides a higher
data rate of up to 108 Mbps. Enabling Turbo Mode allows
the access point to provide connections up to 108 Mbps.
• In normal mode, the access point provides a channel
bandwidth of 20 MHz, and supports the maximum number
of channels permitted by local regulations (e.g., 11 channels
for the United States). In Turbo Mode, the channel
bandwidth is increased to 40 MHz to support the increased
data rate. However, this reduces the number of channels
supported (e.g., 5 channels for the United States).

access point. (Range: 1 - 32 characters)
Default Setting
smc
Command Mode
Interface Configuration (Wireless)
Command Usage
Clients that want to connect to the wireless network via an
access point must set their SSIDs to the same as that of the
access point.
Example
beacon-interval
This command configures the rate at which beacon signals are
transmitted from the access point.
Syntax
beacon-interval <interval>
interval - The rate for transmitting beacon signals.
(Range: 20-1000 milliseconds)
Default Setting
100

Command Mode
Interface Configuration (Wireless)
Command Usage
The beacon signals allow wireless clients to maintain contact
with the access point. They may also carry
power-management information.
Example
dtim-period
This command configures the rate at which stations in sleep
mode must wake up to receive broadcast/multicast
transmissions.
Syntax
dtim-period <interval>
interval - Interval between the beacon frames that transmit
broadcast or multicast traffic. (Range: 1-255 beacon frames)
Default Setting
2
Command Mode
Interface Configuration (Wireless)
Command Usage
• The Delivery Traffic Indication Map (DTIM) packet interval
value indicates how often the MAC layer forwards
broadcast/multicast traffic. This parameter is necessary to
wake up stations that are using Power Save mode.
• The DTIM is the interval between two synchronous frames
with broadcast/multicast information. The default value of 2
SMC-AP(if-wireless g)#beacon-interval 150
SMC-AP(if-wireless g)#
Command Line Interface
6-78
indicates that the access point will save all broadcast/
multicast frames for the Basic Service Set (BSS) and
forward them after every second beacon.
• Using smaller DTIM intervals delivers broadcast/multicast
frames in a more timely manner, causing stations in Power
Save mode to wake up more often and drain power faster.
Using higher DTIM values reduces the power used by
stations in Power Save mode, but delays the transmission
of broadcast/multicast frames.
Example
fragmentation-length
This command configures the minimum packet size that can be
fragmented when passing through the access point.
Syntax
fragmentation-length <length>
length - Minimum packet size for which fragmentation is
allowed. (Range: 256-2346 bytes)
Default Setting
2346
Command Mode
Interface Configuration (Wireless)
Command Usage
• If the packet size is smaller than the preset Fragment size,
the packet will not be segmented.
• Fragmentation of the PDUs (Package Data Unit) can
increase the reliability of transmissions because it increases
the probability of a successful transmission due to smaller
frame size. If there is significant interference present, or
SMC-AP(if-wireless g)#dtim-period 100
SMC-AP(if-wireless g)#
Interface Commands
6-79
collisions due to high network utilization, try setting the
fragment size to send smaller fragments. This will speed up
the retransmission of smaller frames. However, it is more
efficient to set the fragment size larger if very little or no
interference is present because it requires overhead to send
multiple frames.
Example
rts-threshold
This command sets the packet size threshold at which a Request
to Send (RTS) signal must be sent to the receiving station prior to
the sending station starting communications.
Syntax
rts-threshold <threshold>
threshold - Threshold packet size for which to send an RTS.
(Range: 0-2347 bytes)
Default Setting
2347
Command Mode
Interface Configuration (Wireless)
Command Usage
• If the threshold is set to 0, the access point never sends
RTS signals. If set to 2347, the access point always sends
RTS signals. If set to any other value, and the packet size
equals or exceeds the RTS threshold, the RTS/CTS
(Request to Send / Clear to Send) mechanism will be
enabled.
• The access point sends RTS frames to a receiving station
to negotiate the sending of a data frame. After receiving an
SMC-AP(if-wireless g)#fragmentation-length 512
SMC-AP(if-wireless g)#
Command Line Interface
6-80
RTS frame, the station sends a CTS frame to notify the
sending station that it can start sending data.
• Access points contending for the wireless medium may not
be aware of each other. The RTS/CTS mechanism can
solve this “Hidden Node” problem.
Example
authentication
This command defines the 802.11 authentication type allowed by
the access point.
Syntax
authentication <open | shared>
•open - Accepts the client without verifying its identity using
a shared key.
•shared - Authentication is based on a shared key that has
been distributed to all stations.
Default Setting
open
Command Mode
Interface Configuration (Wireless)
Command Usage
• Shared key authentication can only be used when WEP is
enabled with the encryption command, and at least one
static WEP key has been defined with the key command.
• When using WPA or 802.1x for authentication and dynamic
keying, the access point must be set to open.

that it sends to client devices. Other keys can be used for
decryption of data from clients.
• When using IEEE 802.1x, the access point uses a dynamic
WEP key to encrypt unicast and broadcast messages to
802.1x-enabled clients. However, because the access point
sends the WEP keys during the 802.1x authentication
process, these keys do not have to appear in the client’s
WEP key list.
Example
transmit-power
This command adjusts the power of the radio signals transmitted
from the access point.
Syntax
transmit-power <signal-strength>
signal-strength - Signal strength transmitted from the access
point. (Options: full, half, quarter, eighth, min)
Default Setting
full
Command Mode
Interface Configuration (Wireless)
Command Usage
• The “min” keyword indicates minimum power.
• The longer the transmission distance, the higher the
transmission power required. But to support the maximum
number of users in an area, you must keep the power as low
as possible. Power selection is not just a trade off between
coverage area and maximum supported clients. You also

security.
Syntax
multicast-cipher <AES | TKIP | WEP>
•AES - Advanced Encryption Standard
•TKIP - Temporal Key Integrity Protocol
•WEP - Wired Equivalent Privacy
Default Setting
WEP
Command Mode
Interface Configuration (Wireless)
Command Usage
• WPA enables the access point to support different unicast
encryption keys for each client. However, the global
encryption key for multicast and broadcast traffic must be
the same for all clients. This command sets the encryption
type that is supported by all clients.
• If any clients supported by the access point are not WPA
enabled, the multicast-cipher algorithm must be set to WEP.
• WEP is the first generation security protocol used to encrypt
data crossing the wireless medium using a fairly short key.
Communicating devices must use the same WEP key to
encrypt and decrypt radio signals. WEP has many security
flaws, and is not recommended for transmitting highly
sensitive data.
• TKIP provides data encryption enhancements including
per-packet key hashing (i.e., changing the encryption key
on each packet), a message integrity check, an extended
initialization vector with sequencing rules, and a re-keying
mechanism.
Interface Commands
6-87
• TKIP defends against attacks on WEP in which the
unencrypted initialization vector in encrypted packets is
used to calculate the WEP key. TKIP changes the
encryption key on each packet, and rotates not just the
unicast keys, but the broadcast keys as well. TKIP is a
replacement for WEP that removes the predictability that
intruders relied on to determine the WEP key.
• AES has been designated by the National Institute of
Standards and Technology as the successor to the Data
Encryption Standard (DES) encryption algorithm, and will
be used by the U.S. government for encrypting all sensitive,
nonclassified information. Because of its strength, and
resistance to attack, AES is also being incorporated as part
of the 802.11 standard.
Example
wpa-clients
This command defines whether Wi-Fi Protected Access (WPA) is

Command Usage
Wi-Fi Protected Access (WPA) provides improved data
encryption, which was weak in WEP, and user authentication,
which was largely missing in WEP. WPA uses the following
security mechanisms.
Enhanced Data Encryption through TKIP
WPA uses Temporal Key Integrity Protocol (TKIP). TKIP
provides data encryption enhancements including per-packet
key hashing (i.e., changing the encryption key on each
packet), a message integrity check, an extended initialization
vector with sequencing rules, and a re-keying mechanism.
Enterprise-level User Authentication via 802.1x and EAP
To strengthen user authentication, WPA uses 802.1x and the
Extensible Authentication Protocol (EAP). Used together,
these protocols provide strong user authentication via a central
RADIUS authentication server that authenticates each user on
the network before they join it. WPA also employs “mutual
authentication” to prevent a wireless client from accidentally
joining a rogue network.

This command specifies whether Wi-Fi Protected Access (WPA)
is to use 802.1x dynamic keys or a pre-shared key.
Syntax

•dynamic - WPA with 802.1x dynamic keys.
•pre-shared-key - WPA with a pre-shared key.
Default Setting
dynamic
Command Mode
Interface Configuration (Wireless)
Command Usage
• When the WPA mode is set to “dynamic,” clients are
authenticated using 802.1x via a RADIUS server. Each
client has to be WPA-enabled or support 802.1x client
software. A RADIUS server must also be configured and be
available in the wired network.
• In the dynamic mode, keys are generated for each wireless
client associating with the access point. These keys are
regenerated periodically, and also each time the wireless
client is re-authenticated.
• When the WPA mode is set to “pre-shared-key,” the key
must first be generated and distributed to all wireless clients
before they can successfully associate with the access point.

VLAN Commands
The access point can enable the support of VLAN-tagged traffic
passing between wireless clients and the wired network. Up to 64
VLAN IDs can be mapped to specific wireless clients, allowing
users to remain within the same VLAN as they move around a
campus site.
When VLAN is enabled on the access point, a VLAN ID (a
number between 1 and 4095) can be assigned to each client after
successful authentication using IEEE 802.1x and a central
RADIUS server. The user VLAN IDs must be configured on the
RADIUS server for each user authorized to access the network. If
a user does not have a configured VLAN ID, the access point
assigns the user to its own configured native VLAN ID.
Note: When VLANs are enabled, the access point’s Ethernet port drops
all received traffic that does not include a VLAN tag. To maintain
network connectivity to the access point and wireless clients, be
sure that the access point is connected to a device port that
supports IEEE 802.1Q VLAN tags.

Troubleshooting
Check the following items before you contact local Technical
Support.
1. If wireless clients cannot access the network, check the
following:
• Be sure the access point and the wireless clients are
configured with the same Service Set ID (SSID).
• If authentication or encryption are enabled, ensure that
the wireless clients are properly configured with the
appropriate authentication or encryption keys.
• If authentication is being performed through a RADIUS
server, ensure that the clients are properly configured on
the RADIUS server.
• If authentication is being performed through IEEE 802.1x,
be sure the wireless users have installed and properly
configured 802.1x client software.
• If MAC address filtering is enabled, be sure the client’s
address is included in the local filtering database or on the
RADIUS server database.
• If the wireless clients are roaming between access points,
make sure that all the access points and wireless devices
in the Extended Service Set (ESS) are configured to the
same SSID, and authentication method.
Troubleshooting
A-2
2. If the access point cannot be configured using the Telnet, a
web browser, or SNMP software:
• Be sure to have configured the access point with a valid
IP address, subnet mask and default gateway.
• If VLANs are enabled on the access point, the
management station should be configured to send tagged
frames with a VLAN ID that matches the access point’s
native VLAN (default VLAN 1, page 5-13). However, to
manage the access point from a wireless client, the AP
Management Filter should be disabled (page 5-13).
• Check that you have a valid network connection to the
access point and that the Ethernet port or the wireless
interface that you are using has not been disabled.
• If you are connecting to the access point through the wired
Ethernet interface, check the network cabling between the
management station and the access point. If you are
connecting to access point from a wireless client, ensure
that you have a valid connection to the access point.
• If you cannot connect using Telnet, you may have
exceeded the maximum number of concurrent Telnet
sessions permitted (i.e, four sessions). Try connecting
again at a later time.
3. If you cannot access the on-board configuration program via a
serial port connection:
• Be sure you have set the terminal emulator program to
VT100 compatible, 8 data bits, 1 stop bit, no parity and
9600 bps.
• Check that the null-modem serial cable conforms to the
pin-out connections provided in Appendix B.
Troubleshooting
A-3
4. If you forgot or lost the password:
• Set the access point to its default configuration by
pressing the reset button on the back panel for 5 seconds
or more. Then use the default user name “smcadmin” with
the password “admin” to access the management
interface.
5. If all other recovery measure fail, and the access point is still
not functioning properly, take any of these steps:
• Reset the access point’s hardware using the console
interface, web interface, or through a power reset.
• Reset the access point to its default configuration by
pressing the reset button on the back panel for 5 seconds
or more. Then use the default user name “smcadmin” with
the password “admin” to access the management
interface.

Twisted-Pair Cable Assignments
Caution: DO NOT plug a phone jack connector into the RJ-45 port.
Use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards.
For 10/100BASE-TX connections, a twisted-pair cable must have
two pairs of wires. Each wire pair is identified by two different
colors. For example, one wire might be red and the other, red with
white stripes. Also, an RJ-45 connector must be attached to both
ends of the cable.
Caution: Each wire pair must be attached to the RJ-45 connectors in a
specific orientation. (See “Straight-Through Wiring” on page
B-3 and “Crossover Wiring” on page B-3 for an explanation.)
The following figure illustrates how the pins on the RJ-45

10/100BASE-TX Pin Assignments
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP)
cable for RJ-45 connections: 100-ohm Category 3 or better cable
for 10 Mbps connections, or 100-ohm Category 5 or better cable
for 100 Mbps connections. Also be sure
that the length of any
twisted-pair connection does not exceed 100 meters (328 feet).
The RJ-45 port on the access point is wired with MDI pinouts.
This means that you must use crossover cables for connections
to PCs or servers, and straight-through cable for connections to
switches or hubs. However, when connecting to devices that
support automatic MDI/MDI-X pinout configuration, you can use
either straight-through or crossover cable.
10/100BASE-TX MDI and MDI-X Port Pinouts

2 Receive Data minus (RD-) Transmit Data minus (TD-)
3 Transmit Data plus (TD+) Receive Data plus (RD+)
6 Transmit Data minus (TD-) Receive Data minus (RD-)
4,5,7,8 Not used Not used
Note: The “+” and “-” signs represent the polarity of the wires that make up each wire pair.

Straight-Through Wiring
Because the 10/100 Mbps port on the access point uses an MDI
pin configuration, you must use “straight-through” cable for
network connections to hubs or switches that only have MDI-X
ports. However, if the device to which you are connecting
supports auto-MDIX operation, you can use either
“straight-through” or “crossover” cable.
Crossover Wiring
Because the 10/100 Mbps port on the access point uses an MDI
pin configuration, you must use “crossover” cable for network
connections to PCs, servers or other end nodes that only have
MDI ports. However, if the device to which you are connecting
supports auto-MDIX operation, you can use either
“straight-through” or “crossover” cable.
