Introduction
Overview
The Enterasys Networks Wireless Access Point 3000 is an IEEE 802.11a/b/g (RBT3K‐AG and
RBT3K‐AG‐G), or an IEEE 802.11b/g only (RBT3K‐1G), 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 seamless integration into a 10/100 Mbps Ethernet LAN.
In addition, the access point offers full network management capabilities through an easy to configure Web interface, and a command line interface for initial configuration and troubleshooting.
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.
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).

Network Configuration
Overview
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 to reduce interference
• Decrease the signal strength of neighboring access points
• Increase the channel separation of neighboring access points (e.g., up to 5 channels of separation for 802.11b, up to 4 channels for 802.11a, or 5 channels for 802.11g)

Ad Hoc Wireless LAN (no Access Point 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. Figure 2‐1
shows an example of this configuration.

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

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.
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), as shown in Figure 2‐3
. By placing the access points so that a continuous coverage area is created, wireless users within this ESS can roam freely. All wireless network card adapters and Access Point 3000s, within a specific ESS, must be configured with the same SSID.

Initial Configuration
Overview
You can manage the RoamAbout Access Point 3000 with:
• Command Line Interface (CLI) that you access through a direct connection to the console port
For a description of how to use the CLI, refer to
Appendix A: Using the Command Line Interface .
To view a list of all the CLI commands, refer to
• Web interface that you access through Internet Explorer or another Web browser
Note: You must click on the Apply button at the bottom of each Web interface page for the configuration changes on that page to take effect.
• An SNMP manager, such as Enterasys Networks NetSight management applications.
Refer to the RoamAbout Access Point 3000 Hardware Installation Guide for information on the physical setup of the access point.
Initial Configuration Steps
You can perform the initial configuration steps through the CLI or the Web interface.
The access point requests an IP address from a Dynamic Host Configuration Protocol (DHCP) server by default. If a DHCP server does not respond, then the access point uses the default address, 192.168.1.1.
If you utilize a DHCP server to provision new elements in your IP network, use your DHCP server or other utilities to determine the IP address assigned to this access point. Then, use the DHCP assigned IP address to connect to the access point.
RoamAbout Access Point 3000 Configuration Guide 3-1
Initial Configuration Steps
Using the CLI
To use the CLI to minimally configure the access point, follow these steps:
1.
Make a serial connection to the access point’s console port as described in the RoamAbout
Access Point 3000 Hardware Installation Guide.
2.

TCP / IP Settings
TCP / IP Settings
Configuring the Access Point 3000 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 the access point if the access point already has an IP address that is reachable through your network.
By default, the Access Point 3000 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 (refer to
Chapter 3). After you have network access to the access point, you can use the Web browser interface to modify the IP configuration, if needed.
Note: If there is no DHCP server on your network, then the access point will automatically start up with its default IP address, 192.168.1.1.
RoamAbout Access Point 3000 Configuration Guide 4-5
TCP / IP Settings
Using Web Management
Select TCP/IP Settings from the menu.
• DHCP allows you to enable or disable the 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
Note: Enterasys Networks recommends that you reset the access point after changing the DHCP client status.
• IP Address
– IP Address is the IP address of the access point. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods.
– Subnet Mask is the mask that identifies the host address bits used for routing to specific subnets.
– 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.
– Primary DNS and Secondary DNS are the IP addresses of the Domain Name Servers (DNS) 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.
4-6 Advanced Configuration
TCP / IP Settings
• Web Servers
– HTTP Server allows the access point to be monitored or configured from a browser.
– HTTP Port specifies the port to be used by the Web browser interface.
– HTTPS Server allows you to enable or disable the secure HTTP server on the access point.
– HTTPS Port specifies the UDP port number used for HTTPS/SSL connection to the access pointʹs Web interface.
• Telnet & SSH Settings
Telnet allows you to manage the access point from anywhere in the network. Telnet is not secure from hostile attacks. Therefore, it is recommended to use the Secure Shell (SSH). The
SSH protocol uses generated public keys to encrypt all data transfers passing between the access point and SSH‐enabled management station clients and ensures that data traveling over the network arrives unaltered.
– Telnet Server disables or enables the Telnet server. Default: Enabled.
– SSH Server disables or enables the SSH server. Default: Enabled.
– SSH Port Number sets the UDP port for the SSH server. Range: 1‐22, 24‐79, 81‐442, 444‐
2312, 2314‐65535; Default: 22
Notes: SSH Port Number range may vary from range specified here; range varies based on default ports defined on access point and port usage by other applications.
After software upgrade or configuration reset, the SSH server requires approximately five minutes to generate host encryption keys. The SSH server is disabled while the keys are being generated.

RADIUS
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 Access Point 3000 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
If you are using MAC authentication, you must provide the following information to the RADIUS
Server Network Administrator:
• MAC Address of your wireless client. This becomes the username, which is case‐sensitive
(lower‐case), and in the format: 00‐01‐f4‐ab‐cd‐ef.
• Configure the RADIUS server to authenticate using the default password of
“NOPASSWORD” for all the MAC address based user names.
Notes: This guide assumes that you 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.
If you are using RADIUS, it is highly recommended that you assign a static IP address to ensure that the address doesn’t change via DHCP.
RoamAbout Access Point 3000 Configuration Guide 4-9
RADIUS
Using Web Management
Select RADIUS from the menu.
Configure the following settings to use RADIUS authentication on the access point:
• IP Address/Server Name specifies the IP address or host name of the RADIUS server. The IP address must be an IP Version 4 address.
• Port Number is the UDP port number used by the RADIUS server for authentication. This value must match the configuration of your primary RADIUS authentication server. Range:
1024‐65535; Default: 1812
• Key is the 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 (seconds) is the number of seconds the access point waits for a reply from the RADIUS server before re‐sending a request. Range: 1‐60 seconds; Default: 5
• Retransmit attempts is the number of times the access point tries to re‐send 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.
• RADIUS Accounting enables or disables the AP to send RADIUS accounting information for clients to the RADIUS accounting server. Default: Disable
• Accounting Port specifies the specific destination port for RADIUS accounting packets. A value between 1024 and 65535. This value must match the configuration of your primary RADIUS accounting server. Default: 1813
4-10 Advanced Configuration
RADIUS
• Interim Update Timeout determines how often to send accounting updates from the access point to the server for this session. This value can be overridden by the RADIUS server.
Default: 3600 seconds (one hour), Range: 60 seconds (one minute) to 86400 seconds (one day).
Secondary Radius Server Setup is used to configure a second 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.
Using the CLI
From the global configuration mode, use the radius‐server address command to specify the address of the primary RADIUS server, or the radius‐server secondary address command to specify the address of the secondary RADIUS server. (The following example configures settings for the primary RADIUS server.) Use the radius‐server or radius server secondary and key, port,
port‐accounting, retransmit, timeout, and timeout‐iterim commands to configure the other
RADIUS server parameters. Use the show radius command from the Exec mode to display the current settings for the primary and secondary RADIUS servers.

PPPoE
PPPoE
Since many Internet Service Providers (ISP) use Point‐to‐Point Protocol over Ethernet (PPPoE) to establish communications with end users, the access point includes a built‐in client for this protocol. You can configure the access point to support PPPoE as an authentication method to establish communications with end users.
Using Web Management
Select PPPoE Settings from the menu.
• PPPoE: enables the access point to support PPPoE as an authentication method to establish communications with end users through an ISP. Default: Disable
• Username: The username assigned by your service provider for the PPPoE tunnel. The range is
1 to 63 alphanumeric characters.
• Password: The password assigned by your service provider for the PPPoE tunnel. The range is
1 to 63 alphanumeric characters.
• Service Name: The service name assigned by your service provider for the PPPoE. The service name may be required by some service providers. The range is 1 to 63 alphanumeric characters.
• IP Allocation Mode: Specifies how IP addresses for the PPPoE tunnel are configured on the RJ‐
45 interface. The allocation mode depends on the type of service you have purchased from the
ISP. If Automatically allocated is selected, DHCP is used to allocate the IP addresses for the
PPPoE connection. If static addresses have been assigned to you by the ISP, you must manually enter the assigned addresses. The default setting is Automatically allocated.
4-12 Advanced Configuration
PPPoE
• Local IP Address: The IP address of the local end of the PPPoE tunnel. If you selected Static assigned, you must enter the IP address.
• Remote IP Address: The IP address of the remote end of the PPPoE tunnel. If you selected Static assigned, you must enter the IP address.
• DNS Negotiation Mode: Allows you to enable or disable DNS. DNS servers are used to translate host computer names into IP addresses. PPPoE clients can request a primary and secondary
DNS server from the network connection device at the remote end of the PPPoE tunnel. This request is passed to the remote end during the IP Control Protocol (IPCP) negotiation phase during session initialization.
• Echo Interval: Sets the interval between sending echo requests for the PPPoE tunnel.
Default 10.
• Echo Failure: Echo requests are used to verify the integrity of the link through the PPPoE tunnel. Devices at either end of the link can issue an echo‐request. Devices receiving an echo‐ request must return an echo‐reply. If a link is busy with large data transfers, the echo‐reply may not be issued in a timely manner causing the link to timeout. If you experience this kind of problem, try extending the echo failure count or the echo interval. Default 3.
Using the CLI
From the config mode, enter the interface ethernet command. Use the ip pppoe to enable PPPoE, or no ip pppoe to disable it.
From the if‐ethernet mode, select from the following:
• Use the pppoe ip allocation mode static command to use fixed addresses assigned by the ISP.
• Use the pppoe ip allocation mode automatic command to use IP addresses that are dynamically assigned by the ISP.
• Use the pppoe ipcp dns command to request allocation of IP addresses for Dynamic Naming
System (DNS) servers from the device at the remote end of the PPPoE tunnel. Or, use the no pppoe ipcp dns command.
• Use the pppoe lcp echo-interval and pppoe lcp echo-failure commands to set the Link Control

QoS
QoS
When you configure QoS (Quality of Service) on the access point, you can select specific network traffic, prioritize it, and use congestion‐management and congestion‐avoidance techniques to provide preferential treatment. Implementing QoS in your wireless LAN makes network performance more predictable and bandwidth utilization more effective.
The access point uses a weighted‐fair queuing scheme. Precedence is granted to the highest priority based on a weighted queuing scheme of all priorities, granting all priorities the ability to transmit/receive data.
Eight priority classes are defined. Network managers determine actual mappings. The highest priority is seven and the lowest priority is 0. For example, if you select 5 as the priority, 5 receives higher priority than those set with 0, 1, 2, 3, or 4 and lower priority than those set with 6 and 7 as their priority.
Using Web Management
Select QoS from the menu. The QoS Settings and Status page appears. The QoS mode selections are displayed in the following screen.
4-22 Advanced Configuration
QoS
• QoS Mode drop‐down menu selections:
– Source Address allows you to specify priorities based on source MAC address. Specify source MAC addresses and associated priority levels in the MAC Address table.
– Destination Address allows you to specify priorities based on destination MAC address.
Specify destination MAC addresses and associated priority levels in the MAC Address table.
– Ethernet Type allows you to specify priorities based on Ethernet types. Specify Ethernet types and associated priority levels in the Ethernet Type table. If you are using the CLI, the Ethernet type must be specified in the format HEX 0000‐FFFF (see the ISO Designator table listed in the Filter Control Web page).
– 802.1p is a specification that provides Layer 2 switches the ability to prioritize traffic (and perform dynamic multicast filtering). The prioritization specification works at the media access control (MAC) framing layer of the OSI model. To be compliant with 802.1p, Layer
2 switches must be capable of grouping incoming LAN packets into separate traffic classes.
Other than selecting 802.1p, and then clicking on Apply, there is no other user intervention on the access point. Priorities are set on the switch.
• SVP Status enables or disables the AP QoS to utilize Speculation Voice Priority (SVP) to give voice packets priority over data packets on the AP. Default: Disable
• QoS Classifications are set in conjunction with the selected QoS mode. See

Rogue AP Detection
Rogue AP Detection
This feature scans the airwaves and collects information about access points in the area.
It lists access points found during the scan on the Neighbor AP Detection Status page after the scan is complete.
If you enable the RADIUS authentication setting, this feature also identifies rogue APs. It performs a RADIUS server look up for the MAC address of each access point found. It reports access points whose MAC addresses it finds in the RADIUS server on the Neighbor AP Detection Status page. It reports access points whose MAC addresses it does not find as rogue APs in the syslog.
The term "rogue AP" is used to describe an access point that is not authorized to participate on the network.
It may not have the proper security settings in place. Rogue AP’s can potentially allow unauthorized users access to the network. In addition, a legitimate client may mistakenly associate to a rogue AP with invalid encryption settings and not to the AP that has been configured for it to use. This can cause a denial of service problem.
RoamAbout Access Point 3000 Configuration Guide 4-29
Rogue AP Detection
Using Web Management
Select Rogue AP Detection from the menu. The Rogue AP Detection selections are displayed in the following screen.
• RADIUS Authentication enables the access point to discover rogue access points. Enabling
RADIUS Authentication causes the access point to check the MAC address/Basic Service Set
Identifier (BSSID) of each access point that it finds against a RADIUS server to determine whether the access point is allowed. With RADIUS authentication disabled, the access point can identify its neighboring access points only; it cannot identify whether the access points are allowed or are rogues. If you enable RADIUS authentication, you must configure a RADIUS server (on the RADIUS page) for this access point.

The access point includes an on‐board agent that supports SNMP versions 1, 2c, and 3. Access to the on‐board agent using SNMP v1 and v2c is controlled by community strings. To communicate with the access point, a management station must first submit a valid community string for authentication.
Access to the on‐board agent using SNMP v3 provides additional security features that cover message integrity, authentication, and encryption; as well as controlling notifications that are sent to specified user targets.
You can use a network management application such as Enterasys Networks NetSight Atlas
Console to manage the Access Point 3000 via SNMP from a network management station.
To implement SNMP management, the Access Point 3000 must have an IP address and subnet mask, configured manually or dynamically. Once an IP address has been configured, appropriate

• Engine‐ID is used for SNMPv3 to identify the access point in a network of multiple access points.
– Entering the Engine‐ID invalidates all engine IDs that have been previously configured.
– If the Engine‐ID is deleted or changed, all SNMP users will be cleared. You will need to reconfigure all users.
• SNMP Users allows you configure the security requirement of users access.
Note: If you are going to use Group Lists, you must set up the Groups before adding the SNMP users.
– User specifies string to identify an SNMP user. (32 characters maximum)
– Group is the name of the SNMP group to which the user is assigned (32 characters maximum). There are three pre‐defined groups: RO, RWAuth, or RWPriv.
– Auth Type specifies the authentication type used for user authentication: “md5” or “none.”
– Passphrase is the user password required when authentication, Auth Type, is used (8 to 32 characters).
– Priv Type is the encryption type used for SNMP data encryption: “des” or “none.”
– Passphrase is the user password required when data encryption, Priv Type, is used (8 to 32 characters).
– Action: Add adds a new user; Edt allows you to edit an existing user; Del deletes the user.
• Groups allow you to combine the users into groups of authorization and privileges. Users must be assigned to groups that have the same security levels. If a user who has “AuthPriv” security (uses authentication and encryption) is assigned to a read‐only (RO) group, the user will not be able to access the database. An AuthPriv user must be assigned to the RWPriv group with the AuthPriv security level.

– RWAuth is a read/write group using authentication, but no data encryption. Users in this group send SNMP messages that use an MD5 key/password for authentication, but not a
DES key/password for encryption.
– RWPriv is a read/write group using authentication and data encryption. Users in this group send SNMP messages that use an MD5 key/password for authentication and a DES key/password for encryption. Both the MD5 and DES key/passwords must be defined.
– Security Level
‐ noAuthNoPriv uses no authentication or privacy
‐ authNoPriv requires authentication, but not privacy
‐ authPriv requires authentication and privacy
– WriteView allows write access to set objects.
– Action Add adds a new group; Edt allows you to edit an existing group; Del deletes the group.
• SNMP Targets
– Target ID is the name you enter to identify the SNMP target. Maximum: 32 characters.
– IP Address is the IP address of the user.
– UDP port is the UDP port of the server.
– SNMP user is the name of the user. This name must match the name you entered in SNMP
Users.
– Filter ID is the filter ID that you entered in the SNMP Filter section.
– Action Add adds a new target; Edt allows you to edit an existing target; Del deletes the target.
• SNMP Filter
– New Filter is the name you enter to identify a filter that includes or excludes certain notifications. Maximum: 32 characters.
– Filter Type specifies whether the filter includes or excludes the specified notification.
Includes means that notifications that are part of the subtree will be filtered out. Exclude means that notifications that are part of the subtree will be sent.
– Subtree is an OID string that specifies the family of subtrees included or excluded by this filter. The string must be preceded with a period (.).
For example, .1.3.6.1.
– Action Add adds a filter; Edt allows you to edit an existing filter; Del deletes the filter.

Upgrading Firmware
You can upgrade the Access Point 3000 software from a local file on the management workstation, or from an FTP or TFTP server. New software may be provided periodically on the Wireless Web site ( http://www.enterasys.com/products/wireless ).
After upgrading new software, you must reboot the Access Point 3000 to implement the new code.
Until a reboot occurs, the Access Point 3000 will continue to run the software it was using before the upgrade started.
Before upgrading new software, verify that the Access Point 3000 is connected to the network and has been configured with a compatible IP address and subnet mask.
Bulk upgrades can be done using Enterasys Networks NetSight Inventory Manager.
If you need to download from an FTP or TFTP server, perform the following additional tasks:
• Obtain the IP address of the FTP or TFTP server where the access point software is stored.
• Verify that the image is in the appropriate directory on the server.
• 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, or the network port to which it is attached, with the same VLAN ID. If you are managing the access point from a wireless client, the VLAN ID for the wireless client must be configured on a RADIUS server.

Configuring SNTP
Simple Network Time Protocol (SNTP) allows the Access Point 3000 to set its internal clock based on periodic updates from a time server. Maintaining an accurate time on the access point enables the system log to record meaningful dates and times for event entries.
The Access Point 3000 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. When disabled, you manually set the date and time of the system clock.
– Primary Server is the IP address of an SNTP time server that the access point attempts to poll for a time update. Default: 137.92.140.80
– Secondary Server is the IP address of a secondary SNTP 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. Default: 192.43.244.18
Note: If SNTP is disabled, you can manually set the date and time of the system clock.
– Set Time (SNTP Server disabled) allows you to manually set the current date and time for the location of this access point.
• 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.
– Enter Time Zone sets 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 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
Radio Interface
The IEEE 802.11a and 802.11b/g interfaces include configuration options for radio signal characteristics, Virtual APs (VAPs), and wireless security features.
The configuration options for both radio interfaces are nearly identical, and are both covered in this section of the manual.
The Radio Settings section includes options for the radio characteristics of the interface, and the network definition of the default radio interface and up to seven VAPs per radio interface.
Radio Signal Characteristics
The access point can operate in several different radio modes, IEEE 802.11a only, 802.11b only,
802.11g only, 802.11b/g only, or a mixed 802.11a/b/g mode. Also note that 802.11g is backward compatible with 802.11b.
Note: The radio channel settings for the Access Point 3000 are limited by local regulations, which determine the number of channels that are available.
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.
You define network information and radio signal characteristics for the radio interface. The network information applies only to the Service Set Identifier (SSID) specified for the default radio interface. You specify unique network information for the SSID of each VAP you define for this radio interface (in addition to the default radio interface), if any.
Virtual APs (VAPs)
In addition to defining network characteristics for the default radio interface, you can define network characteristics for up to seven VAPs per radio interface. Each default radio interface and
VAP has its own unique Service Set Identifier (SSID) with which clients can associate, using a variety of security and authentication options.
RoamAbout Access Point 3000 Configuration Guide 4-47

Radio Interface
• Interface Status disables/enables use of this default radio interface. Default: Enable.
Notes: Before enabling the radio card, you must set the country selection using the CLI. For more information, see the RoamAbout Access Point 3000 Hardware Installation and Configuration Guide.
You must enable the default radio interface in order to configure VAPs on this radio interface.
• Description is the description you provide to identify this default radio interface.
• Network Name (SSID) is the name that you specify for the basic service set provided by the default radio interface. All clients that want to connect to the wired LAN through the default radio interface must set their SSIDs to this SSID.
• Native VLAN ID is the VLAN ID for this default radio interface. The access point assigns this
VLAN ID to all client traffic using this radio interface unless you assign unique VLAN IDs to clients through the RADIUS server using RFC 3580 (Section 3.31) tunnel attributes.
Using RFC 3580 (Section 3.31) tunnel attributes, you must configure user VLAN IDs (1‐4095) on the RADIUS server for each client authorized to access the network. The RADIUS server then assigns a VLAN ID to a client after successful authentication using IEEE 802.1x and a central RADIUS server. If a client does not have a configured VLAN ID, the access point assigns the client to the native VLAN ID for the radio interface.
When setting up VLAN IDs for each user on the RADIUS server, be sure to use the RADIUS attributes and values as indicated in

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.
• Secure Access specifies whether clients can access the default radio interface network by discovering and automatically configuring the SSID, or whether clients must be already configured with the SSID. Default: Disable
– Enabled, this default radio interface denies access to wireless clients that do not have the default radio interface network name (SSID) already configured. This default radio interface does not broadcast its network name, so that clients with operating systems like
Windows XP do not see the name show up in wireless LAN configuration dialogs.
– Disabled, this default radio interface broadcasts its network name, and clients can discover and use the SSID to access this default radio interface’s wireless network.
•
IBSS Relay: In conjunction with IBSS Relay Control settings (see Filter Control on page 4‐17),
controls whether clients associated with the default radio interface can establish wireless communications with each other through the AP. Default: Disable
If you enable IBSS Relay, clients can establish wireless communications with each other through the AP. If you set the IBSS Relay Control to All VAP, then clients associated with all
IBSS enabled radio interfaces or VAPs can establish wireless communications with each other.
If you set the IBSS Relay Control to Per VAP, only the clients associated with the same (IBSS enabled) radio interface or VAP can communicate with each other.
• Maximum Associations (0‐255): Specifies the number of clients allowed to associate with this radio interface.
• Turbo Mode. (802.11a ONLY.) 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 3000 to provide connections up to 108 Mbps. Default: Disabled
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., 13 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).
4-50 Advanced Configuration
Radio Interface
• VLAN enables or disables VLAN tagging support on this default radio interface. 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. Default: Disable
– Enable: 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.
– Disable: When VLAN filtering is disabled, this default radio interface ignores the VLAN tags on any received frames.
Note: If the radio interface has VLANs enabled, then VLANs are enabled on all VAPs associated with this radio interface.
• Radio Channel specifies the channel number for the operating radio channel in the access point.
– The 802.11a 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.
– The 802.11b/g 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: 6
• Auto Channel Select enables the access point to automatically select an unoccupied radio channel. Default: Enabled
• Working Mode (802.11b/g ONLY). 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 interfere with the operation of other radio devices in the service area. (Options: 100%, 50%, 25%, 12.5%, minimum.) Default: 100%
• Maximum Tx Data Rate identifies the highest desired transmission speed for the broadcast traffic as forwarded by the AP to the wireless LAN.
– 802.11a defines 6, 9, 12, 18, 24, 36, 48, 54 Mbps data rates in the 5 GHz band.
– 802.11b only defines: 1, 2, 5.5, 11 Mbps data rates in the 2.4 GHz band.
– 802.11g only, or 802.11b and 802.11g defines: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps data rates.
RoamAbout Access Point 3000 Configuration Guide 4-51
Radio Interface
• Multicast Data Rate sets the speed to support for multicast traffic.
The faster the transmit speed, the shorter the coverage area at that speed. For example, an AP with an 802.11b 11 Mbit/s Radio Card can communicate with clients up to a distance of 375 feet in a semi‐open environment. However, only clients within the first 165 feet can communicate at 11 Mbit/s. Clients between 165 and 230 feet communicate at 5.5 Mbit/s.
Clients between 230 and 300 feet communicate at 2 Mbit/s; and clients between 300 to 375 feet communicate at 1 Mbit/s.
• Beacon Interval (20‐1000) sets 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. Default: 100 Ms
• Data Beacon Rate (1‐255) sets 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
• Fragment Length (256‐2346) specifies an alternative frame length for packets. When transmitting data via the wireless network, your wireless network automatically splits up the file or message in a number of different packets that are re‐assembled again by the communication partner. RoamAbout products use standard IEEE 802.11 compatible frame lengths, where different lengths apply for each Transmit Rate. Fragmentation will apply alternative (usually shorter) frame lengths to split and reassemble the wireless data frames.
Default: 2346.
• RTS Threshold (0‐2347) sets the Request to Send (RTS) threshold frame length between 0 and
2,327 bytes. You can configure the access point to initiate an RTS frame sequence always, never, or only on frames longer than a specified length. If the packet size is smaller than the preset RTS threshold size, the RTS/CTS mechanism will NOT be enabled.
The access point sends request to send (RTS) frames to a particular receiving station to negotiate the sending of a data frame. After receiving an RTS, the station send a CTS (Clear to
Send) frame to acknowledge the right for the station to send data frames. The access point contending for the medium may not be aware of each other. The RTS/CTS mechanism can solve this ʺHidden Node Problemʺ.
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. Range: 0‐2347 bytes: Default: 2347 bytes
4-52 Advanced Configuration
Radio Interface
Virtual AP:
• VAP (1‐7) enables or disables the selected virtual access point (VAP).
• Description that you provide for this VAP.
• Network Name (SSID) the name that you specify for the basic service set provided by this VAP.
All clients that want to connect to the wired LAN through this VAP must set their SSIDs to this
SSID.
• Native VLAN ID is the VLAN ID for this VAP. The access point assigns this VLAN ID to all client traffic using this VAP unless you assign unique VLAN IDs to clients through the RADIUS server using
RFC 3580 (Section 3.31) tunnel attributes. For more information on tunnel attributes, see the description under radio interface.
• Secure Access specifies whether clients can access the default radio interface network by discovering and automatically configuring the SSID, or whether clients must be already configured with the SSID. Default: Disable
– Enabled specifies that this VAP denies access to wireless clients that do not have its network name (SSID) already configured. This VAP does not broadcast its network name, so that clients with operating systems like Windows XP do not see the name show up in wireless LAN configuration dialogs.
– Disabled specifies that this VAP broadcasts its network name, and clients can discover and use the SSID to access this default radio interface’s wireless network. Default: Disable
•
IBSS Relay: In conjunction with IBSS Relay Control settings (see Filter Control on page 4‐17),
controls whether clients associated with this VAP can establish wireless communications with each other through the AP. Default: Disable
If you enable IBSS Relay, clients can establish wireless communications with other clients. If you set the IBSS Relay Control to All VAP, then clients associated with all IBSS enabled radio interfaces or VAPs can establish wireless communications with each other. If you set the IBSS
Relay Control to Per VAP, only the clients associated with the same (IBSS enabled) radio interface or VAP can communicate with each other.
• Maximum Associations (0‐255) specifies the number of clients allowed to associate with this
VAP.

The Access Point 3000 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: to verify that clients attempting to connect to the network are authorized users.
• Traffic Encryption: to protect data passing between the access point and clients from interception and eavesdropping.
The access point can implement one or a combination of the following security mechanisms:
• Wired Equivalent Privacy (WEP)
• AES (802.11i ready)
• IEEE 802.1x
• Wireless MAC address filtering
• Wi‐Fi Protected Access (WPA)
4-60 Advanced Configuration
Security
The security mechanisms that you may employ depend upon the level of security required, the network and management resources available, and the software support provided on wireless clients.

RoamAbout Access Point 3000 Configuration Guide 4-61
Security
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. For more robust wireless security, the Access Point 3000 provides Wi‐Fi
Protected Access (WPA) and AES for improved data encryption and user authentication.
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.
Using Web Management
Click on Security in the menu under the type of interface (802.11a or 802.11b/g) that you want to configure.
4-62 Advanced Configuration
Security
• Statics Key Settings specify up to four static WEP encryption keys that clients may use with either the default interface or a VAP associated with this radio .
– Key Type specifies 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.
– Key Len specifies whether to use 64, 128 or 152 bit keys.
– Key: Specify a key in the appropriate format for the type of key type and length that you selected.
Hexadecimal: 64‐bit enter a 10 digit key; 128‐bit enter a 26 digit key; 152‐bit enter a 32 digit key.
Alphanumeric: 64‐bit enter a 5 character key; 128‐bit enter a 13 character key; 152‐bit enter a 16 character key.
– Transmit Key Select specifies the key number to use for encryption for the default interface and each of the VAPs. 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.
After completing the Static Key Settings, click default interface or any of the VAPs for which you want to specify security settings.
The Security Settings page appears.
RoamAbout Access Point 3000 Configuration Guide 4-63
Security
• 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 (the default setting): 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.
– 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.
Note: To use 802.1x on wireless clients requires a 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.
4-64 Advanced Configuration
Security
• Data Encryption Setup enables or disables 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)
Note: You must enable WEP encryption in order to enable all types of encryption on the access point; however, you do not need to define WEP keys for WPA.
• WPA Clients sets the specified radio interface or VAP to:
– Required ‐ allow only WPA‐enabled clients to access the network;
– Supported ‐ allow WPA‐enabled clients and clients only capable of supporting WEP to access the network;
– Not supported ‐ does not allow WPA‐enabled clients to access the network.
Default: Supported
• WPA Key Management: You can configure WPA to work in an enterprise environment using
IEEE 802.1x and a RADIUS server for user authentication. For smaller networks, you can configure WPA using a common pre‐shared key for client authentication with the access point.
– WPA authentication over 802.1x sets this radio interface or VAP to the WPA enterprise mode. This mode uses IEEE 802.1x to authenticate users and to dynamically distribute encryption keys to clients.
– WPA Pre‐shared Key sets this radio interface or VAP to the WPA mode for small networks.
This mode uses a common password string that is manually distributed. You must configure all wireless clients associated with this radio interface or VAP with the same key. You must specify the key string under the WPA Pre‐Shared Key Type section of the
Security Settings page.
• Multicast Cipher Mode selects an encryption method for the global key used for multicast and broadcast traffic, which is supported by all wireless clients associated with this radio interface or VAP.
– WEP specifies that 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 (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 designated by the National Institute of Standards and Technology as the successor to the Data Encryption Standard (DES) encryption algorithm.
RoamAbout Access Point 3000 Configuration Guide 4-65
Security
• WPA Pre‐shared Key Type specifies the WPA pre‐shared key type and the key for client authentication with this radio interface or VAP. If you use the WPA pre‐shared‐key, you must configure all wireless clients with the same key entered here to communicate with this interface or VAP.
– Hexadecimal uses a key made up of a string of 64 hexadecimal numbers.
– Alphanumeric uses a key in an easy‐to‐remember form of letters and numbers. The string must be from 8 to 63 characters and can include spaces.
– WPA Pre‐Shared Key specifies the pre‐shared key in the appropriate format for the type of key you selected: a string of 64 hexadecimal numbers, or a string of 8 to 63 alphanumeric characters.
802.1x 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.
• 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 indicates that 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 indicates that the access point supports 802.1x authentication only for clients initiating the 802.1x authentication process (that is, 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 indicates that 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.
4-66 Advanced Configuration
Security
When you enable 802.1x, you can also enable the broadcast and session key rotation intervals.
– 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 specifies the interval at which the access point refreshes unicast session keys for associated clients. (Range: 0‐1440 minutes; Default: 0 means disabled)
– 802.1x Session Timeout sets 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 to the network. Only if re‐authentication fails is network access blocked. Default: 60 minutes.
• MAC Authentication configures how the access point uses MAC addresses to authorize wireless clients to access the network. This authentication method 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 Access Point 3000 or remotely on a central RADIUS server. (Default: Local MAC)
– Local MAC indicates that the MAC address of the associating station is compared against the local database stored on the access point. Local MAC Authentication enables the local database to be set up.
– RADIUS MAC specifies that the MAC address of the associating station is sent to a configured RADIUS server for authentication.
To use a RADIUS authentication server for MAC address authentication, the access point must be configured to use a RADIUS server, see RADIUS (
).
– Disable specifies that the access point does not check an associating station’s MAC address.
If you specify RADIUS MAC for this default interface or VAP, you must specify the following parameters:
– MAC Authentication Password specifies the authentication password this radio interface or
VAP sends to the RADIUS server to authenticate MAC addresses.
– MAC Authentication Session Timeout specifies the amount of time after which you want a
MAC authentication session to timeout between the AP and the RADIUS server.
If you specify Local MAC for this default interface or VAP, you must specify Local MAC
Authentication settings that configure the local MAC authentication database. The MAC database provides a mechanism to take certain actions based on a wireless client’s MAC address. You can configure 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
“Allow”.
‐ Allow permits access for all MAC addresses except those listed in the local database as
“Deny”.
RoamAbout Access Point 3000 Configuration Guide 4-67
Security
– Local MAC Filter Settings adds MAC addresses and permissions into the local MAC database.
‐ MAC Address is the physical address of a client. Enter six pairs of hexadecimal digits separated by hyphens; for example, 00‐01‐F4‐12‐AB‐89.
‐ Permission specifies whether to allow or deny access to this MAC address. Allow permits access; Deny blocks access; Delete removes the specified MAC address entry 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.
CLI Commands for 802.1x Authentication
Use the 802.1x supported or 802.1x required command from the interface wireless or interface wireless: VAP configuration mode to enable 802.1x authentication, or the no 8021.x to disable it.
Use the 802.1x broadcast‐key‐refresh‐rate, 802.1x broadcast‐key‐refresh‐rate, and 802.1x session‐
timeout commands to set the broadcast and session key refresh rates, and the re‐authentication timeout.

4-82 Advanced Configuration
Status Information
• Station Address is the MAC address of the wireless client.
• Authenticated displays if the station has been authenticated. The two basic methods of authentication supported for 802.11 wireless networks are “open system” and “shared key.”
Open‐system authentication accepts any client attempting to connect to the access point without verifying its identity. The shared‐key approach uses Wired Equivalent Privacy (WEP) to verify client identity by distributing a shared key to stations before attempting authentication.
• Associated displays if the station has been successfully associated with the access point. Once authentication is completed, stations can associate with the current access point, or reassociate with a new access point. The association procedure allows the wireless system to track the location of each mobile client, and ensure that frames destined for each client are forwarded to the appropriate access point.
• Forwarding Allowed displays if the station has passed 802.1x authentication, and is now allowed to forward traffic to the access point.
• Key Type displays the current key type used for encryption.
• Tx displays the number of packets/bytes that this station has transmitted.
• Rx displays the number of packets/bytes that this station has received.

RoamAbout Access Point 3000 Configuration Guide A-1
Accessing the CLI
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 Dynamic Host Configuration Protocol (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:
RoamAbout 3000#configure
Enter configuration commands, one per line. End with CTRL/Z
RoamAbout 3000(config)#interface ethernet
Enter Ethernet configuration commands, one per line.
RoamAbout 3000(if-ethernet)#no ip dhcp
DHCP client state has changed. Please reset AP for change to take effect.
RoamAbout 3000(if-ethernet)#exit
RoamAbout 3000#reset board
Reboot system now? <y/n>: y
Username: admin
Password:********
RoamAbout 3000#configure
Enter configuration commands, one per line. End with CTRL/Z
RoamAbout 3000(config)#interface ethernet
Enter Ethernet configuration commands, one per line.
RoamAbout 3000(if-ethernet)#ip address 10.1.0.1 255.255.255.0 10.1.0.254
RoamAbout 3000(if-ethernet)#
After you configure the access point with an IP address, you can open a Telnet session by performing the following 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
“RoamAbout 3000#” prompt to show that you are using executive access mode (for example.,
Exec).
3.
Enter the necessary commands to complete your desired tasks.
4.
When finished, exit the session with the “exit” command.
After entering the Telnet command, the login screen displays the following:
Username: admin
Password:********
RoamAbout 3000#
Note: You can open up to four sessions to the device via Telnet.

Entering Commands
Entering Commands
This section describes how to enter the 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 described below:
• 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:
RoamAbout 3000(config)#username dave
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 the input using the Tab key, the CLI displays the remaining characters of a partial keyword up to the point of ambiguity. For example, typing con followed by a tab displays the command up to “configure.”
RoamAbout Access Point 3000 Configuration Guide A-3
Getting Help on Commands
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 list of valid keywords for a specific command. For example, the command “show ?” displays a list of possible show commands:
RoamAbout 3000#show ? al all System snapshot for tech support
authentication Show Authentication parameters
bootfile Show bootfile name
cdp Show CDP Global Information
events Show event log on console

The command “show interface ?” will display the following information:
RoamAbout 3000#show interface ?
ethernet Show Ethernet interface
wireless Show wireless interface
<cr>
RoamAbout 3000#show interface
Partial Keyword Lookup
If you terminate a partial keyword with a question mark, alternatives that match the initial letters are provided. (Remember not to leave a space between the command and question mark.) For example “s?” shows all the keywords starting with “s.”
RoamAbout 3000#show s?
snmp sntp station svp system
RoamAbout 3000#show s
A-4
Getting Help on Commands
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.
Viewing 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.
RoamAbout Access Point 3000 Configuration Guide A-5
Understanding Command Modes
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 Table A‐1
.
Table A-1 Command Class Modes

Exec Commands
When you open a new console session on the 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” and the password “password”. The command prompt displays as
“RoamAbout 3000#” for Exec mode.
Username: admin
Password: ********
RoamAbout 3000#
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.
The Interface‐Wireless configuration also includes a sub‐mode for configuring up to seven
Virtual Access Points (VAPs) on each of the radio interfaces.
A-6
Understanding Command Modes
To enter the Global Configuration mode, enter the command configure in Exec mode. The system prompt changes to “RoamAbout 3000(config)#” which gives you access privilege to all Global
Configuration commands.
RoamAbout 3000#configure
Enter configuration commands, one per line. End with CTRL/Z
RoamAbout 3000(config)#
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 changes to “RoamAbout 3000(if‐ethernet)#,” or RoamAbout 3000(if‐wireless a)” indicating that you have access privileges to the associated commands.
You can use the end command to go back a level, or the exit command to go back to the Exec mode.
RoamAbout 3000(config)#interface ethernet
Enter Ethernet configuration commands, one per line.
RoamAbout 3000(if-ethernet)#
RoamAbout 3000(if-ethernet)#end
RoamAbout 3000(config)#
RoamAbout 3000(config)#interface wireless a
Enter Wireless configuration commands, one per line.
RoamAbout 3000(if-wireless a)#
RoamAbout 3000(if-wireless a)#exit
RoamAbout 3000#
To enter the VAP sub‐mode, you must specify the “VAP” command while in either the “interface
wireless a,” or “interface wireless g” configuration modes.
RoamAbout 3000(config)#interface wireless a
Enter Wireless configuration commands, one per line.
RoamAbout 3000(if-wireless a)#vap 2
RoamAbout 3000(if-wireless a: VAP[2])#
RoamAbout 3000(if-wireless a: VAP[2])#exit

user‐name is the user‐defined string for the SNMP user. (32 characters maximum)
Default Setting

Command Mode
Global Configuration
Command Usage
• Up to ten SNMPv3 users can be configured on the access point.
• The SNMP engine ID is used to compute the authentication/privacy digests from the pass phrase. You should therefore configure the engine ID with the snmp‐server engine‐id command before using this configuration command.
• The access point enables SNMP v3 users to be assigned to three pre‐defined groups. Other groups cannot be defined. The available groups are:
– RO ‐ A read‐only group using no authentication and no data encryption. Users in this group use no security, either authentication or encryption, in SNMP messages they send to the agent. This is the same as SNMP v1 or SNMP v2c.
– RWAuth ‐ A read/write group using authentication, but no data encryption. Users in this group send SNMP messages that use an MD5 key/password for authentication, but not a
DES key/password for encryption.
– RWPriv ‐ A read/write group using authentication and data encryption. Users in this group send SNMP messages that use an MD5 key/password for authentication and a DES key/password for encryption. Both the MD5 and DES key/passwords must be defined.
Note: If you are going to use Group Lists, you must set up the Groups before adding the SNMP users.
• Users must be assigned to groups that have the same security levels. If a user who has
“AuthPriv” security (uses authentication and encryption) is assigned to a read‐only (RO) group, the user will not be able to access the database. An AuthPriv user must be assigned to the RWPriv group with the AuthPriv security level.
RoamAbout Access Point 3000 Configuration Guide A-67
Command Groups
• The command prompts for the following information to configure an SNMP v3 user:
– User Name is the user‐defined string for the SNMP user. (32 characters maximum)
– Group Name is the name of the SNMP group to which the user is assigned (32 characters maximum). There are three pre‐defined groups: RO, RWAuth, or RWPriv.
– Authtype is the authentication type used for user authentication: “md5” or “none.”
– Passphrase is the user password required when authentication or data encryption is used
(8 – 32 characters).
– Privacy is the encryption type used for SNMP data encryption: “des” or “none.”

The show snmp groups command displays the group names (RO, RWAuth, or RWPriv) and the group security settings.
Users must be assigned to groups that have the same security levels. If a user who has “AuthPriv” security (uses authentication and encryption) is assigned to a read‐only (RO) group, the user will not be able to access the database. An AuthPriv user must be assigned to the RWPriv group with the AuthPriv security level.
Use the snmp‐server engine‐id command to define the SNMP v3 engine before assigning users to groups. Use the snmp‐server user command to assign users to one of the three groups and set the appropriate authentication and encryption types to be used. To view the current SNMP v3 engine
ID, use the show snmp command. To view SNMP users and group settings, use the show snmp
users or show snmp group‐assignments commands.

802.1x Port Authentication Commands
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 user credentials for authentication. Client authentication is then verified via by a RADIUS server using EAP (Extensible Authentication Protocol) before the access point grants client access to the network. The commands are listed in
Table A-13

Command Mode
Interface Configuration (Wireless)
Interface Configuration (Wireless): VAP
Command Usage
• Configures 802.1x for the default interface and up to seven VAPs per radio interface.
• When 802.1x is disabled, the access point does not support 802.1x authentication for any station. After successful 802.11 association, each client is allowed to access the network.
• When 802.1x is 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 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.

Interface Configuration (Wireless ‐ 802.11a)
Command Usage
• 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., 12 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).

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 is the 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 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.

fragmentation-length
This command configures the minimum packet size that can be fragmented when passing through the access point.
Syntax
fragmentation-length <length>
length is the 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 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.

Command Groups
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 is the 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 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.

Command Usage
• Use this command for the default interface or any of the seven VAPs configurable per radio interface.
• If you use WEP key encryption, the access point uses the transmit key to encrypt multicast and broadcast data signals 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.

Interface Configuration (Wireless)
Interface Configuration (Wireless): VAP
Command Usage
• Use this command for the default interface or any of the seven VAPs configurable per radio interface.
• 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.
• TKIP defends against attacks on WEP in which the un‐encrypted 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.

• 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.

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.

QoS Commands
When you configure QoS (Quality of Service) on the access point, you can select specific network traffic, prioritize it, and use congestion‐management and congestion‐avoidance techniques to provide preferential treatment. Implementing QoS in your wireless LAN makes network performance more predictable and bandwidth utilization more effective.
Eight classes are defined for the priority. Network managers determine actual mappings. The highest priority is seven and the lowest priority is 0. For example, if you select 5 as the priority, 5 receives higher priority than those set with 0, 1, 2, 3, or 4 and lower priority than those set with 6 and 7 as their priority.
Use the commands described in Table A‐16 to configure QoS parameters.

Rogue AP Commands
ʺRogue APʺ describes an access point that is not authorized to participate on the network. It may not have the proper security settings in place. Rogue APs can potentially allow unauthorized users access to the network. In addition, a legitimate client may mistakenly associate to a Rogue
AP with invalid encryption settings and not to the AP that has been configured for it to use. This can cause a denial of service problem.
This feature scans the airwaves and collects information about access points in the area. It lists neighbor access points found during the scan in the Neighbor AP Detection Status page after the scan is complete.
In addition, if RADIUS is enabled, it performs a RADIUS server look up for the MAC address of each access point found. It reports access points whose MAC addresses it finds in the RADIUS server in the Neighbor AP Detection status list. It reports access points whose MAC addresses it does not find as rogue APs in the syslog.
Use the commands described in Table A‐16 to configure and use rogue AP.

VLAN Commands
The access point can employ VLAN tagging support to control access to network resources and increase security. VLANs separate traffic passing between the access point, associated clients, and the wired network. You can assign a VLAN to each of the access points radio interfaces, a management VLAN for the access point, and a VLAN to up to 64 associated clients.
Each wireless client associated to the access point is assigned to the native VLAN ID (a number between 1 and 4095) for the radio interface. If IEEE 802.1x is being used to authenticate wireless clients, specific VLAN IDs can be configured on the RADIUS server to be assigned to each client.
Using IEEE 802.1x and a central RADIUS server, up to 64 VLAN IDs can be mapped to specific wireless clients. The access point allows traffic tagged with assigned VLAN IDs or the native
VLAN ID to access clients associated on the radio interface.
When VLAN support is enabled, the access point tags traffic passing to the wired network with the appropriate VLAN ID, either an assigned client VLAN ID, native VLAN ID, or the management VLAN ID. Traffic received from the wired network must also be tagged with one of these known VLAN IDs. Received traffic that has an unknown VLAN ID or no VLAN tag is dropped.
When VLAN support is disabled, the access point does not tag traffic passing to the wired network and ignores the VLAN tags on any received frames.
When setting up VLAN IDs for each user on the RADIUS server, be sure to use the RADIUS attributes and values as indicated in
.

.
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.

• Changing the VLAN status of the access point requires a system reboot.
• When VLANs are enabled, the access point tags frames received from wireless clients with the native VLAN ID for the radio interface. If IEEE 802.1x is being used to authenticate wireless clients, specific VLAN IDs can be configured on the RADIUS server to be assigned to each client. Using IEEE 802.1x and a central RADIUS server, up to 64 VLAN IDs can be mapped to specific wireless clients.
• If the VLAN ID has not been configured for a client on the RADIUS server, then the frames are tagged with the native VLAN ID of the radio interface.
• When using IEEE 802.1x to dynamically assign VLAN IDs, the access point must have
802.1x authentication enabled and a RADIUS server configured. Wireless clients must also support 802.1x client software.
• Traffic entering the Ethernet port must be tagged with a VLAN ID that matches the access point’s management VLAN ID, a radio interface native VLAN ID, or with a VLAN tag that matches one of the wireless clients currently associated with the access point.

Troubleshooting Steps
Check the following items before contacting technical support.
1.
If wireless clients cannot access the network, check the following: a.
Be sure the access point and the wireless clients are configured with the same Service Set
ID (SSID).
b. If authentication or encryption are enabled, ensure that the wireless clients are properly configured with the appropriate authentication or encryption keys.
c.
If authentication is being performed through a RADIUS server, ensure that the clients are properly configured on the RADIUS server.
d. If authentication is being performed through IEEE 802.1x, be sure the wireless users have installed and properly configured 802.1x client software.
e.
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.
f.
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.
2.
If the access point cannot be configured using Telnet, a Web browser, or SNMP software: a.
Be sure to have configured the access point with a valid IP address, subnet mask and default gateway.
b. 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, see page 6‐82**). However, to manage the access point from a wireless client, the AP Management Filter should be disabled (page 6‐52**). c.
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.
d. 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 the access point from a wireless client, ensure that you have a valid connection to the access point.
e.
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: a.
Be sure you have set the terminal emulator program to VT100 compatible, 8 data bits, 1 stop bit, no parity and 9600 bps. b. Check that the null‐modem serial cable conforms to the pin‐out connections provided in the RoamAbout Access Point 3000 Hardware Installation Guide.
4.
If you forgot or lost the password:
You can set the access point to its default configuration by pressing the reset button on the back panel for 5 seconds or more. You will loose all of your configuration settings. Then, use the default user name “admin” with the password “password” to access the management interface.
5.
If all other recovery measures fail, and the access point is still not functioning properly, take any of these steps: a.
Reset the access point’s hardware using the console interface, Web interface, or through a power reset.
b. Reset the access point to its default configuration by pressing the reset button on the back panel for 5 seconds or more. You will loose all of your configuration settings. Then, use the default user name “admin” with the password “password” to access the management interface.
Maximum Distance Tables
through Table C‐3 list the wireless distances.
Note: Maximum distances posted below are actual tested distance thresholds. However, there are many variables such as barrier composition and construction and local environmental interference that may impact your actual distances and cause you to experience distance thresholds far lower than those posted in the following tables.
