LAPAC1750PRO Access Point Software User Manual

Section 1: Getting Started

The LAPAC1750PRO Access Point provides continuous, high-speed access between wireless devices and Ethernet devices. It is an advanced, standardsbased solution for wireless networking in businesses of any size. The access point (AP) enables wireless local area network (WLAN) deployment while providing state-of-the-art wireless networking features.

The access point works in Standalone Mode, which means it is an individual access point in your network. You manage the device through a Web-based user interface (UI) or SNMP (Simple Network Management Protocol.

This document describes how to perform the setup, management, and maintenance of the access point in Standalone Mode.

Before you power on a new access point, review the following sections to check required hardware and software components, client configurations, and compatibility issues. Make sure you have everything you need for a successful launch and test of your new or extended wireless network.

This section contains the following topics:

• Administrator’s Computer Requirements

• Wireless Client Requirements

• Online Help, Supported Browsers, and Limitations

• Dynamic and Static IP Addressing

• Installing the Access Point

• Configuring the Ethernet Settings

• Configuring IEEE 802.1X Authentication

• Configuring Security on the Access Point

To manage the access point by using the Web interface, the AP needs an IP address. If you use VLANs or IEEE 802.1X Authentication (port security) on your network, you might need to configure additional settings on the AP be fore it can connect to the network.

NOTE:

The access point is not designed to function as a gateway to the Internet. To connect your WLAN to other LANs or the Internet, you need a gateway device.

Administrator’s Computer Requirements

The following table describes the minimum requirements for the administrator’s computer for configuration and administration of the access point through a Web-based user interface (UI).

Table 1: Requirements for the Administrator’s Computer

Required Software or Component

Description

Ethernet Connection to the Access Point

The computer used to configure the first access point must be connected to the access point by an Ethernet cable.

Wireless Connection to the Network

After initial configuration and launch of the first access point on your new wireless network, you can make subsequent configuration changes through the Administration Web pages using a wireless connection to the internal network. For wireless connection to the access point, your administration device will need Wi-Fi capability similar to that of any wireless client: a portable or built-in Wi-Fi client adapter that supports one or more of the IEEE 802.11 modes in which you plan to run the access point.

Section 1: Getting Started

LAPAC1750PRO Access Point Software User Manual

Web Browser and Operating System

Configuration and administration of the access point is provided through a Web-based user interface hosted on the access point. We recommend using one of the following supported Web browsers to access the access point Administration Web pages:

• Microsoft® Internet Explorer® version 9.x or

11.x (with up-to-date patch level for either major version)

• Mozilla Firefox version 26.x

• Google Chrome version 32.x

• Safari version 5.x

The administration Web browser must have JavaScript™ enabled to support the interactive features of the administration interface.

Security Settings Ensure that security is disabled on the wireless

client used to initially configure the access point.

Wireless Client Requirements

The access point provides wireless access to any client with a properly configured Wi-Fi client adapter for the 802.11 mode in which the access point is running. The access point supports multiple client operating systems. Clients can be laptop or desktop computers, personal digital assistants (PDAs), or any other handheld, portable or stationary device equipped with a Wi-Fi adapter and supporting drivers.

In order to connect to the access point, wireless clients need the software and hardware described in the following table.

Table 2: Requirements for Wireless Clients

Required Component Description

Wi-Fi Client Adapter Portable or built-in Wi-Fi client adapter that

supports one or more of the IEEE 802.11 modes in which you plan to run the access point. (IEEE

802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac modes are supported.)

Wireless Client Software

Client software, such as Microsoft Windows Supplicant, configured to associate with the access point.

Client Security Settings

Security should be disabled on the client used to do initial configuration of the access point.

If the Security Mode on the access point is set to anything other than plain text, wireless clients will need to set a profile to the authentication mode used by the access point and provide a valid username and password, certificate, or similar user identity proof. Security modes are Static WEP, IEEE

802.1X, WPA with RADIUS server, and WPA-PSK.

For information about configuring security on the access point, see ”Virtual Access Point (VAP).”

Online Help, Supported Browsers, and Limitations

Section 1: Getting Started

LAPAC1750PRO Access Point Software User Manual

Figure 1: Administrator UI Online Help

Dynamic and Static IP Addressing on the AP

When you power on the access point, the built-in DHCP client searches for a DHCP server on the network in order to obtain an IP address and other network information. If the AP does not find a DHCP server on the network, the AP continues to use its default Static IP Address (192.168.1.252) until you reassign it a new static IP address (and specify a static IP addressing policy) or until the AP successfully receives network information from a DHCP server.

To change the connection type and assign a static IP address by using the Web UI, see “VLAN and IPv4 Address” on page 29.

NOTE:

If you do not have a DHCP server on your internal network, and do not plan to use one, the first thing you must do after powering on the access point is change the connection type from DHCP to static IP. You can either assign a new static IP address to the AP or continue using the default address. We recommend assigning a new static IP address so that if you bring up another WLAN AP on the same network, the IP address for each AP will be unique.

Recovering an IP Address

If you experience trouble communicating with the access point, you can recover a static IP address by resetting the AP configuration to the factory defaults (see “Restoring Configuration” on page 114 and “To Restore the Factory Default

Configuration” on page 114), or you can get a dynamically assigned address by

connecting the AP to a network that has a DHCP server.

Discovering a Dynamically Assigned IP Address

If you have access to the DHCP server on your network and know the MAC address of your AP, you can view the new IP address associated with the MAC address of the AP.

NOTE:

The MAC address of access point is shown on product label and brown box label.

Installing the Access Point

To access the Administration Web UI, you enter the IP address of the AP into a Web browser. You can use the default IP address of the AP (192.168.1.252) to log on to the AP and assign a static IP address, or you can use a DHCP server on you network to assign network information to the AP. The DHCP client on the AP is enabled by default.

To install the access point, use the following steps:

1. Connect the AP to an administrative PC by using a LAN connection or a

direct-cable connection.

Section 1: Getting Started

LAPAC1750PRO Access Point Software User Manual

• To use a LAN connection, connect one end of an Ethernet cable to the

network port on the access point and the other end to the same hub where your PC is connected, as shown in the following figure.

The hub or switch you use must permit broadcast signals from the access point to reach all other devices on the network.

• To use a direct-cable connection, connect one end of an Ethernet straight-

through or crossover cable to the network port on the access point and the other end of the cable to the Ethernet port on the PC, as shown in the following figure. You can also use a serial cable to connect the serial port on the AP to a serial port on the administrative computer.

For initial configuration with a direct Ethernet connection and no DHCP server, be sure to set your PC to a static IP address in the same subnet as the default IP address on the access point. (The default IP address for the access point is

192.168 .1.252.)

If you use this method, you will need to reconfigure the cabling for subsequent startup and deployment of the access point so that the access point is no longer connected directly to the PC but instead is connected to the LAN (either by using a hub or directly).

NOTE:

It is possible to detect access points on the network with a wireless connection. However, we strongly advise against using this method. In most environments you may have no way of knowing whether you are actually connecting to the intended AP. Also, many of the initial configuration changes required will cause you to lose connectivity with the AP over a wireless connection.

NOTE:

Ethernet Port 1 and Port 2 can be used together in Link Aggregation Mode when supported by the connected devices.

2. Connect the power adapter to the power port on the back of the access

point, and then plug the other end of the power cord into a power outlet.

3. Use your Web browser to log on to the access point Administration Web

pages.

• If the AP did not acquire an IP address from a DHCP server on your network,

enter 192.168.1.252 , the default IP address of the AP, in the address field of your browser.

• If you used a DHCP server on your network to automatically configure

network information for the AP, enter the new IP address of the AP into the Web browser.

4. When prompted, enter admin for the user name and admin for the

password, then click Log In.

• When you first log in, the System Summary page for access point

administration is displayed, as the following figure shows.

Section 1: Getting Started

LAPAC1750PRO Access Point Software User Manual

Figure 2: System Summary Page

5. Verify the settings on the System Summary page.

• Review access point description.

For information about the fields on the System Summary page, see “System

Summary” on page 7.

6. If you do not have a DHCP server on the management network and do

not plan to use one, you must change the Connection Type from DHCP to Static IP.

You can either assign a new Static IP address to the AP or continue using

the default address. We recommend assigning a new Static IP address so that if you bring up another access point on the same network, the IP address for each AP will be unique. To change the connection type and assign a static IP address, see “VLAN and IPv4 Address” on page 29.

7. If your network uses VLANs, you might need to configure the

management VLAN ID or untagged VLAN ID on the access point in order for it to work with your network.

For information about how to configure VLAN information, see “VLAN

and IPv4 Address” on page 29.

8. If your network uses IEEE 802.1X port security for network access control,

you must configure the 802.1X supplicant information on the AP.

For information about how to configure the 802.1X user name and

password, see “802.1X Supplicant” on page 65.

Configuring the Ethernet Settings

The default Ethernet settings, which include DHCP and VLAN information, might not work for all networks.

By default, the DHCP client on the access point automatically broadcasts requests for network information. If you want to use a static IP address, you must disable the DHCP client and manually configure the IP address and other network information.

The management VLAN is VLAN 1 by default. This VLAN is also the default untagged VLAN. If you already have a management VLAN configured on your network with a different VLAN ID, you must change the VLAN ID of the management VLAN on the access point.

For information about using the Web interface to configure the Ethernet settings, see “VLAN and IPv4 Address” on page 29.

Section 1: Getting Started

LAPAC1750PRO Access Point Software User Manual

Configuring IEEE 802.1X Authentication

On networks that use IEEE 802.1X, port-based network access control, a supplicant (client) cannot gain access to the network until the 802.1X authenticator grants access. If your network uses 802.1X, you must configure

802.1X authentication information that the AP can supply to the authenticator.

If your network uses IEEE 802.1X see “802.1X Supplicant” on page 65 for information about how to configure 802.1X by using the Web interface.

Verifying the Installation

Make sure the access point is connected to the LAN and associate some wireless clients with the network. Once you have tested the basics of your wireless network, you can enable more security and fine-tune the AP by modifying advanced configuration features.

1. Connect the access point to the LAN.

• If you configured the access point and administrator PC by connecting

both into a network hub, then your access point is already connected to the LAN. The next step is to test some wireless clients.

• If you configured the access point by using a direct cable connection

from your computer to the access point, do the following procedures:

a. Disconnect the cable from the computer and the access point.

b. Connect an Ethernet cable from the access point to the LAN.

c. Connect your computer to the LAN by using an Ethernet cable or a

wireless card.

2. Test LAN connectivity with wireless clients.

Test the access point by trying to detect it and associate with it from

some wireless client devices. For information about requirements for these clients, see “Wireless Client Requirements” on page 2.

3. Secure and configure the access point by using advanced features.

Once the wireless network is up and you can connect to the AP with some

wireless clients, you can add in layers of security, create multiple virtual access points (VAPs), and configure performance settings.

NOTE:

The WLAN AP is not designed for multiple, simultaneous configuration changes. If more than one administrator is logged onto the Administration Web pages and making changes to the configuration, there is no guarantee that all configuration changes specified by multiple users will be applied.

By default, no security is in place on the access point, so any wireless client can associate with it and access your LAN. An important next step is to configure security, as described in “Virtual Access Point (VAP)” on page 43.

Configuring Security on the Wireless

Access Point

You configure secure wireless client access by configuring security for each virtual access point (VAP) that you enable. You can configure up to 8 VAPs per radio that simulate multiple APs in one physical access point. By default, only one VAP is enabled. For each VAP, you can configure a unique security mode to control wireless client access.

Each radio has 8 VAPs, with VAP IDs from 0-7. By default, only VAP 0 on each radio is enabled. VAP0 has the following default settings:

• VLAN ID: 1

• Broadcast SSID: Enabled

• SSID: LinksysSMB24G for Radio 1 (2.4GHz), and LinksysSMB5G for Radio 2

(5GHz)

• Security: None

• MAC Authentication Type: None

• Redirect Mode: None

All other VAPs are disabled by default. The default SSID for VAPs 1–7 is “Virtual Access Point x” where x is the VAP ID.

To prevent unauthorized access to the access point, we recommend that you select and configure a security option other than None for the default VAP and for each VAP that you enable.

For information about how to configure the security settings on each VAP, see

“Virtual Access Point (VAP)” on page 43.

Table 9: Associated Clients

Field Description

Network Shows which VAP the client is associated with. For

example, an entry of wlan0vap2 means the client is associated with Radio 1, VAP 2.

An entry of wlan0 means the client is associated with VAP 0 on Radio 1. An entry of wlan1 means the client is associated with VAP 0 on Radio 2.

Station Shows the MAC address of the associated wireless client.

Section 2: Viewing Access Point System Status

LAPAC1750PRO Access Point Software User Manual

Status The Authenticated and Associated Status shows the

underlying IEEE 802.11 authentication and association status, which is present no matter which type of security the client uses to connect to the AP. This status does not show other (IEEE 802.1X) authentication or association status.

Some points to keep in mind with regard to this field are:

• If the AP security mode is None or Static WEP, the

authentication and association status of clients showing on the Client Associations tab will be in line with what is expected; that is, if a client shows as authenticated to the AP, it will be able to transmit and receive data. (This is because Static WEP uses only IEEE 802.11 authentication.)

• If the AP uses IEEE 802.1X or WPA security, however,

it is possible for a client association to show on this tab as authenticated (via the IEEE 802.11 security) but actually not be authenticated to the AP via the second layer of security.

From Station

These fields report information about traffic sent from a wireless client to the AP.

TS Violate Packets

The number of packets sent from the AP to a wireless client in excess of its active TS downlink bandwidth, or for an access category requiring admission control to which the wireless client has not been admitted.

Link Integrity Monitoring

The access point provides link integrity monitoring to continually verify its connection to each associated client. To do this, the AP sends data packets to clients every few seconds when no other traffic is passing. This allows the AP to detect when a client goes out of range, even during periods when no normal traffic is exchanged. The client connection drops off the list within 300 seconds if these data packets are not acknowledged, even if no disassociation message is received.

TSPEC Client Associations

The TSPEC Client Association Status and Statistics page provides information about the TSPEC client data transmitted and received by this access point. Table 10 shows voice and video packets transmitted and received by the association, along with status information.

The page shows a real-time display of transmit and receive statistics for the TSPEC clients. All transmit and receive statistics shown are totals since the client association started.

A TSPEC is a traffic specification that is sent from a QoS-capable wireless client to an AP requesting a certain amount of network access for the traffic stream (TS) it represents. A traffic stream is a collection of data packets identified by the wireless client as belonging to a particular user priority. An example of a voice traffic stream is a Wi-Fi-certified™ telephone handset that marks its codecgenerated data packets as voice priority traffic. An example of a video traffic stream is a video player application on a wireless laptop that prioritizes a video conference feed from a corporate server.

Time Settings

The Network Time Protocol (NTP) is an Internet standard protocol that synchronizes computer clock times on your network. NTP servers transmit Coordinated Universal Time (UTC, also known as Greenwich Mean Time) to their client systems. NTP sends periodic time requests to servers, using the returned time stamp to adjust its clock. The timestamp is used to indicate the date and time of each event in log messages.

See http://www.ntp.org for more information about NTP.

To configure the address of the NTP server that the AP uses or to set the system time manually, click the Configuration > Administration > Time Settings tab and update the fields as described in Table 16.

NOTE:

The fields available to configure depend on whether you choose to set the system time manually or by using an NTP server.

Figure 14 shows the Time Settings page when the manual option is selected.

Table 16: Time Settings

Field Description

System Clock Source

Set the system time.

• To permit the AP to poll an NTP server, select Network

Time Protocol (NTP).

• To manually configure the time and date, select

Manually. When this option is selected, the AP does not attempt to poll an NTP server.

NTP Server IPv4/ IPv6 Addr/Name

If NTP is enabled, specify the NTP server to use.

You can specify the NTP server by hostname, IPv4 address, or IPv6 address, although using the IPv4/IPv6 address is not recommended as these can change more readily.

If you specify a hostname, note the following requirements:

• The length must be between 1–253 characters.

• Upper and lower case characters, numbers, and

hyphens are accepted.

• The first character must be a letter (a–z or A–Z) or

number (0–9), and the last character cannot be a hyphen.

Time Zone Select your local time zone from the menu. The default is

USA (Pacific).

Adjust Time for Daylight Savings

System will adjust the reported time for Daylight Savings Time (DST), which is also known as Summer Time. When selected, fields to configure Daylight Savings Time settings will appear.

Daylight Savings Start

Configure the date and time to begin Daylight Savings Time for the System Time.

Daylight Saving End

Configure the date and time to end Daylight Savings Time for the System Time.

Daylight Savings Offset

Select the number of minutes to offset DST. The default is 60 (minutes).

NOTE:

After you configure the Time settings, you must click Save to apply the changes and save the changes to startup configuration file. Changing some settings might cause the AP to stop and restart system processes. If this happens, wireless clients will temporarily lose connectivity. We recommend that you change AP settings when WLAN traffic is low.

NOTE:

Hostnames are composed of a series of labels joined with dots, as are all domain names. Each label must be between 1 and 63 characters long, and the entire hostname (including dots) has a maximum of 253 characters.

Log Settings

The Log Settings page shows real-time system logs on the AP such as wireless clients associating with the AP and being authenticated.

From the Log Settings page, you can enable and configure persistent logging to write system logs to non-volatile memory so that the events are not erased when the system reboots. This page also gives you the option of enabling a remote log relay host to capture all system logs and errors in a kernel log.

To view system events, click the Configuration > Administration > Log Settings tab.

Figure 16: Log Settings

Section 3: Configuring the Access Point

LAPAC1750PRO Access Point Software User Manual

Configuring Persistent Logging Options

If the system unexpectedly reboots, log messages can be useful to diagnose the cause. However, log messages are erased when the system reboots unless you enable persistent logging.

Caution!

Enabling persistent logging can wear out the flash (non-volatile) memory and degrade network performance. You should only enable persistent logging to debug a problem. Make sure you disable persistent logging after you finish debugging the problem.

Table 17: Logging Options

Field Description

Persistence Choose Enabled to save system logs to non-volatile memory

so that the logs are not erased when the AP reboots. When persistence is enabled, we can store up to 128 messages in non-volatile memory. Choose Disabled to save system logs to volatile memory. Logs in volatile memory are deleted when the system reboots.

Severity Specify the severity level of the log messages to write to non-

volatile memory. For example, if you specify 2, critical, alert, and emergency logs are written to non-volatile memory. Error messages with a severity level of 3–7 are written to volatile memory.

• 0 — emergency

• 1 — alert

• 2 — critical

• 3 — error

• 4 — warning

• 5 — notice

• 6 — info

• 7 — debug

Depth You can store up to 512 messages in non-volatile memory. Once

the number you configure in this field is reached, the oldest log event is overwritten by the new log event.

NOTE:

To apply your changes, click Save. Changing some settings might cause the AP to stop and restart system processes. If this happens, wireless clients will temporarily lose connectivity. We recommend that you change AP settings when WLAN traffic is low.

Configuring the Log Relay Host for Kernel Messages

The Kernel Log is a comprehensive list of system events (shown in the System Log) and kernel messages such as error conditions, like dropping frames.

You cannot view kernel log messages directly from the Administration Web UI for an AP. You must first set up a remote server running a syslog process and acting as a syslog log relay host on your network. Then, you can configure the access point to send syslog messages to the remote server.

Remote log server collection for AP syslog messages provides the following features:

• Allows aggregation of syslog messages from multiple APs

• Stores a longer history of messages than kept on a single AP

• Triggers scripted management operations and alerts

To use Kernel Log relaying, you must configure a remote server to receive the syslog messages. The procedure to configure a remote log host depends on the type of system you use as the remote host.

NOTE:

The syslog process will default to use port 514. We recommend keeping this default port. However, If you choose to reconfigure the log port, make sure that the port number you assign to syslog is not being used by another process.

Section 3: Configuring the Access Point

LAPAC1750PRO Access Point Software User Manual

Enabling or Disabling the Log Relay Host on the Log Settings Page

To enable and configure Log Relaying on the Log Settings page, set the Log Relay options as described in the following table, and then click Save.

Table 18: Log Relay Host

Field Description

Relay Log Select Enabled to allow the access point to send log messages

to a remote host. Select Disabled to keep all log messages on the local system.

Relay Host Specify the IPv4 address, IPv6 address, or DNS name of the

remote log server.

Relay Port Specify the Port number for the syslog process on the Relay

Host.

Discovery - LLDP

Link Layer Discovery Protocol (LLDP) is defined by the IEEE 802.1AB standard and allows the access point to advertise information about itself such as the system name, port name, system capabilities, and power requirements. This information can help you identify system topology and detect bad configurations on the LAN. The AP also supports the Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-MED), which standardizes additional information elements that devices can pass to each other to improve network management.

Discovery - Bonjour

Bonjour is a software feature that allows the wireless access point and its services to be discovered on a local network using multicast Domain Name System (mDNS) service records. You can either enable or disable the Bonjour component systemwide. The feature is not configurable on any specific network interface.

To set Bonjour status, click the Configuration > Administrator > Discovery - Bonjour tab.

Bonjour Status

Enables or disables Bonjour. The default is Enabled.

The access point uses a default AP IP address assignment if a DHCP server is absent in the network. There is no implementation of IPv4 Link-Local Addressing or IPv6 Stateless Address Auto-configuration for the access point.

DNS-SD and mDNS are used for advertisement of services and hostname lookup. The service types listed in the following table are defined by the DNSSD records and advertised via mDNS by the Bonjour component. The Bonjour component works in both IPv4 and IPv6 networks.
