Introduction

SMC’s EliteConnect 2.4GHz 802.11g Wireless Access Point (SMC2552W-G) is an IEEE 802.11b/g access point that provides transparent, wireless high-speed data communications between the wired LAN and fixed, portable or mobile devices equipped with a 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 802.11b 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.

Radio Characteristics – The IEEE 802.11g standard uses a radio modulation technique known as Orthogonal Frequency Division Multiplexing (OFDM), and a shared collision domain (CSMA/CA). It operates 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

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 2-3.

LED Indicators

The access point includes three status LED indicators, as described in the following figure and table.

Security Slot

The access point includes a Kensington security slot on the rear panel. You can prevent unauthorized removal of the access point by wrapping the Kensington security cable (not provided) around an unmovable object, inserting the lock into the slot, and turning the key.

Console Port

This port is used to connect a console device to the access point through a serial cable. This connection is described under “Console Port Pin Assignments” on page B-4. The console device can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.

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.

1-5

Introduction

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 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.

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. You can mount the access point on a wall as shown in the illustrations on the next page.

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.

Position the mounting bracket on the wall, and mark the holes. The orientation shown in the following figure is the most secure position for mounting the access point. Do not mount the access point with the retaining latches pointing down.

To mount the access point on a plastered brick or concrete wall, first drill four holes 22 mm deep and 3.5 mm in diameter, and press the four included wall plugs firmly into the drilled holes until they are flush with the surface of the wall.

2-1

Hardware Installation

Set the four 5/8-inch number 12 wood screws in the holes, leaving about 3 mm clearence from the wall.

Position the mounting bracket over the wall screws, slide the bracket onto the screws, and then tighten down the screws.

3. Attaching the Bracket – Line up the three mounting points on the bracket with the three mounting slots on the rear of the access point, as directed in the figure on the next page.

Place the mounting points of the bracket into the mounting slots of the access point and while pushing down on the bracket, slide it into position so that the two retaining latches slip into place over the back of the access point.

4. 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.

2-3

Hardware Installation

5. Connect the Power Cord – Connect the power adapter to the access point, and the power cord to an AC power outlet.

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.

6. 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.

7. 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 LAN 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.

8. 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

2-4

Hardware Installation

position the antennas around 45 to 90 degrees from each other.

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.

9. 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, 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 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.

Network Topologies

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.

Network Configuration

Infrastructure Wireless LAN for Roaming Wireless PCs

The Basic Service Set (BSS) defines the communications domain for each access point and its associated wireless clients. The BSS ID is a 48-bit binary number based on the access point’s wireless MAC address, and is set automatically and transparently as clients associate with the access point. The BSS ID is used in frames sent between the access point and its clients to identify traffic in the service area.

The BSS ID is only set by the access point, never by its clients. The clients only need to set the Service Set Identifier (SSID) that identifies the service set provided by one or more access points. The SSID can be manually configured by the clients, can be detected in an access point’s beacon, or can be obtained by querying for the identity of the nearest access point. For clients that do not need to roam, set the SSID for the wireless card to that used by the access point to which you want to connect.

3-4

Network Topologies

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 SMC2552W-G wireless access points within a specific ESS must be configured with the same SSID.

Initial Configuration

The EliteConnect 2.4GHz 802.11g Wireless Access Point SMC2552W-G 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 access point requests an IP address via DHCP by default. If no response is received from a DHCP server, then the access point uses the default address 192.168.2.2. You can also use the command line interface (CLI) as described below to configure a valid address.

Note: Units sold in countries outside the United States are not

configured with a specific country code. You must use the CLI to set the country code and enable wireless operation (page 4-4).

Initial Setup through the CLI

Required Connections

The SMC2552W-G 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.

4-1

Initial Configuration

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 captive retaining screws on the DB-9 connector.

2. Connect the other end of the cable to the RS-232 serial port on the access point.

3. Make sure the terminal emulation software is set as follows:

• Select the appropriate serial port (COM port 1 or 2).

• Set the data rate to 9600 baud.

• Set the data format to 8 data bits, 1 stop bit, and no parity.

• Set flow control to none.

• Set the emulation mode to VT100.

• When using HyperTerminal, select Terminal keys, not

Windows keys.

Note: When using HyperTerminal with Microsoft® Windows® 2000,

make sure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000 Service Pack 2 fixes the problem of arrow keys not functioning in HyperTerminal’s VT100 emulation. See www.microsoft.com for information on Windows 2000 service packs.

4. Once you have set up the terminal correctly, press the [Enter] key to initiate the console connection. The console login screen will be displayed.

For a description of how to use the CLI, see “Using the Command Line Interface” on page 6-1. For a list of all the CLI commands and detailed information on using the CLI, refer to “Command Groups” on page 6-10.

Initial Configuration Steps

Logging In – Enter “admin” for the user name. The default

password is “smcadmin”. The CLI prompt appears displaying “SMC Enterprise AP#.”

Username: admin Password: smcadmin SMC Enterprise AP#

Setting the IP Address – By default, the access point is configured to obtain IP address settings from a DHCP server. You may also 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.

SMC Enterprise AP#configure SMC Enterprise AP(config)#interface ethernet SMC Enterprise AP(config-if)#

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.

accessed using Telnet from any computer attached to the network.

Setting the Country Code – Units sold in the United States are configured by default to use only radio channels 1-11 as defined by FCC regulations. Units sold in other countries are configured by default without a country code (i.e., 99). You must use the CLI to set the country code. Setting the country code restricts operation of the access point to the radio channels permitted for wireless networks in the specified country.

Type “exit” to leave configuration mode. Then type “country?” to display the list of countries. Select the code for your country, and enter the country command again, following by your country code (e.g., IE for Ireland).

System Configuration

TCP / IP Settings

Configuring the SMC2552W-G 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 SMC2552W-G 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 4-3). 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.

5-6

Advanced Configuration

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: Enable)

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).

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 SMC2552W-G 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. If using WPA (PSK) mode then no RADIUS configuration is necessary. Configuration of RADIUS server software is beyond the scope of this guide, refer to the documentation provided with the RADIUS server software.

5-9

System Configuration

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.

5-10

Advanced Configuration

CLI Commands for RADIUS – From the global configuration mode, use the radius-server address command to specify the address of the primary or secondary RADIUS servers. (The following example configures the settings for the primary RADIUS server.) Configure the other parameters for the RADIUS server. Then use the show show radius command from the Exec mode to display the current settings for the primary and secondary RADIUS servers.

System Configuration

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 looking 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.

5-12

Advanced Configuration

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 SMC2552W-G 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 5-9).

• 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.”

5-13

System Configuration

• 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.

Note: Client station MAC authentication occurs prior to the IEEE 802.1x

authentication procedure configured for the access point. However, a client’s MAC address provides relatively weak user authentication, since MAC addresses can be easily captured and used by another station to break into the network. Using 802.1x provides more robust user authentication using user names and passwords or digital certificates. So, although you can configure the access point to use MAC address and 802.1x authentication together, it is better to choose one or the other, as appropriate.

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.

5-14

Advanced Configuration

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 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 (i.e., 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)

5-15

System Configuration

• 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)

5-16

Advanced Configuration

CLI Commands for Local MAC Authentication – Use the

mac-authentication server command from the global configuration mode to enable local MAC authentication. Set the default for MAC addresses not in the local table using the address filter default command, then enter MAC addresses in the local table using the address filter entry command. To remove an entry from the table, use the address filter delete command. To display the current settings, use the show authentication command from the Exec mode.

System Configuration

Filter Control

The access point can employ VLAN ID and network traffic frame filtering to control access to network resources and increase security.

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 SMC2552W-G. 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 16

5-20

Advanced Configuration

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.

Number RADIUS Attribute Value

64 Tunnel-Type VLAN (13) 65 Tunnel-Medium-Type 802 81 Tunnel-Private-Group VLANID

(1 to 4095 in hexadecimal)

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.

5-21

System Configuration

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 SMC2552W-G. 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 SMC2552W-G 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.

SNMP

You can use a network management application such as SMC’s EliteView to manage the SMC2552W-G via the Simple Network Management Protocol (SNMP) from a network management station. To implement SNMP management, the SMC2552W-G 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.

5-25

System Configuration

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)

Changing the Password

Management access to the web and CLI interface on the SMC2552W-G 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 5-20).

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 SMC2552W-G 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)

Upgrading Firmware

You can upgrade new SMC2552W-G 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 SMC2552W-G to implement the new code. Until a reboot occurs, the SMC2552W-G 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.

Before upgrading new software, verify that the SMC2552W-G is connected to the network and has been configured with a compatible IP address and subnet mask.

5-30

Advanced Configuration

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 SMC2552W-G 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 SMC2552W-G 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.

Server Name/IP – The IP address or name of a Syslog server.

Logging Console – Enables the logging of error messages to the

console.

5-34

Advanced Configuration

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.

Error Level Description

Configuring SNTP

Simple Network Time Protocol (SNTP) allows the SMC2552W-G 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 not set, the access point will only record the time from the factory default set at the last bootup.

The SMC2552W-G 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 SMC2552W-G also allows you to disable SNTP and set the

system clock manually.

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

System Configuration

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.

CLI Commands for SNTP – To enable SNTP support on the access point, from the global configuration mode specify SNTP server IP addresses using the sntp-server ip command, then use the sntp-server enable command to enable the service. Use the sntp-server timezone command to set the time zone for your location, and the sntp-server daylight-saving command to set daylight savings. To view the current SNTP settings, use the show sntp command.

Radio Interface

The IEEE 802.11b and 802.11g interface includes configuration options for radio signal characteristics and wireless security features.

The access point can operate in three modes, IEEE 802.11b only,

802.11g only, or a mixed 802.11b/g mode. Also note that 802.11g is backward compatible with 802.11b. The 802.11b/g interface can be configured independently under the following web pages:

• Radio Interface : 802.11b/g

Note: The radio channel settings for the SMC2552W-G are limited by

local regulations, which determine the number of channels that are available.

5-40

Radio Interface

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.

Enable – Enables radio communications on the SMC2552W-G. (Default: Enabled)

5-41

System Configuration

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 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)

SSID Broadcast – The SSID broadcast can be disabled to prevent access to clients without a pre-configured SSID. When disabled, the access point will not include its SSID in beacon messages. Nor will it respond to probe requests from clients that do not include the correct SSID. (Default: Enabled)

Select Antenna Mode – Specifies whether the antenna used will be automatically selected based on best signal reception (i.e., Diversity mode), or will be fixed to use an optional high-gain antenna. (Default: Diversity)

Working Mode – The access point can be configured to support both 802.11b and 802.11g clients simultaneously, 802.11b clients only, or 802.11g clients only. (Default: 802.11b and 802.11g)

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

5-42

Radio Interface

interfere with the operation of other radio devices in the service area. (Options: 100%, 50%, 25%, 12%, minimum; Default: 100%)

Maximum Station Data 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

5-43

System Configuration

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.

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)

5-44

CLI Commands for the 802.11g Wireless Interface – From the global configuration mode, enter the interface wireless g command to access the 802.11g radio interface. Set the interface SSID using the ssid command and, if required, configure a name for the interface using the description command. You can also use the no ssid-broadcast command to stop sending the SSID in beacon messages. Select a radio channel or set selection to Auto using the channel command. Set any other parameters as required. To view the current 802.11g radio settings, use the show interface wireless g command.
