About Instant

This chapter provides the following information:

l Instant Overview on page 11

l What is New in this Release on page 14

Instant Overview

Instant virtualizes Dell Networking W-Series Mobility Controller capabilities on 802.1--capable access points (APs), creating a feature-rich enterprise-grade wireless LAN (WLAN) that combines affordability and configuration simplicity.

Instant is a simple, easy to deploy turnkey WLAN solution consisting of oneor more W-IAPs. An Ethernet port with routable connectivity to the Internet or a self-enclosed network is used for deploying an Instant Wireless Network. A Dell Networking W-Series Instant Access Point (W-IAP) can be installed at a single site or deployed across multiple geographically dispersed locations. Designed specifically for easy deployment and proactive management of networks, Instant is ideal for small customers or remote locations without requiring any onsite IT administrator.

Instant consists of a W-IAP and a Virtual Controller (VC). The VC resides within one of the W-IAPs. In a Instant deployment scenario, only the first W-IAP needs to be configured. After the first W-IAP is configured, the other W-IAPs inherit all the required configuration information from the VC. Instant continually monitors the network to determine the W-IAP that should function as a VC at any time, and the VC will move from one W-IAP to another as necessary without impacting network performance.

Supported W-IAP Platforms

The following table provides a list of W-IAP platforms that support Instant software:

Each W-IAP model has a minimum required Instant software version as shown in Table 3. When a new W-IAP is added into an existing cluster, it can join the cluster only if the existing cluster is running at least the minimum required version of that W-IAP. If the existing cluster is running a version prior to the minimum required version of the new W-IAP, new W-IAP will not come up and may reboot with the reason Image sync fail. To recover from this condition, upgrade the existing cluster to at least the minimum required version of the new W-IAP first, and add the new W-IAP.

Dell recommends that networks with more than 128 W-IAPs be designed as multiple, smaller VC networks with Layer-3 mobility enabled between these networks.

Dell W-IAPs are available in the following variants:

l US (United States)

l JP (Japan)

l RW

Instant UI

The Instant User Interface (UI) provides a standard web-based interface that allows you to configure and monitor a Wi-Fi network. Instant is accessible through a standard web browser from a remote management console or workstation and can be launched using the following browsers:

l Microsoft Internet Explorer 11 or earlier

l Apple Safari 6.0 or later

l Google Chrome 23.0.1271.95 or later

l Mozilla Firefox 17.0 or later

If the Instant UI is launched through an unsupported browser, a warning message is displayed along with a list of recommended browsers. However, the users are allowed to log in using the Continue login link on the Login page.

To view the Instant UI, ensure that JavaScript is enabled on the web browser.

The Instant UI logs out automatically if the window is inactive for 15 minutes.

Dell Networking W-Series Instant 6.5.1.0-4.3.1.0 | User Guide About Instant | 13

Instant CLI

The Instant Command Line Interface (CLI) is a text-based interface that is accessible through a Secure Shell (SSH) session.

SSH access requires that you configure an IP address and a default gateway on the W-IAP and connect the WIAP to your network. This is typically performed when the Instant network on a W-IAP is set up.

What is New in this Release

The following features are introduced in Instant 6.5.1.0-4.3.1.0:

Table 5: New Features

Feature Description

Cluster Security

Support for RFC5997

Clarity Live

Client Match for Access Points in a Zone

Changing the W-IAP Installation Mode

Support for cluster security is introduced to secure control plane messages between WIAPs. Additionally, DTLS is used with cluster security for extended security facilities. Cluster security also provides the option of logging and debugging by organizing the logs into modules which are later used for debugging.

Starting from Instant 6.5.1.0-4.3.1.0, you can configure the RFC5997 feature on the WIAP to send a status request query to the RADIUSserver each time there is an authentication or accounting request timeout. This helps determine if the server is actually down before marking the server as unavailable.

Instant now supports inline monitoring through Clarity Live to identify client connectivity issues and send the data to W-AirWave for analysis. It helps in isolating the root cause of the connectivity issues experienced by receiving regular statistics and updates generated by the events.

Starting from Instant 6.5.1.0-4.3.1.0, the decision to move a client from a home W-IAP to a target W-IAP will be made at the SSID level instead of the radio level, by adding the SSID name to the client match radio database. Client Match will check if the same SSID (zone specific SSID on Home W-IAP) is available on the target W-IAP before it moves the client.

Instant now allows users to change the installation type of the W-IAPs from indoor to outdoor or vice-versa.

Support for New IAP Devices

Instant 6.5.1.0-4.3.1.0 release introduces support for the following new DellW-IAP devices. These new devices do not interoperate with Instant versions lower than Instant 6.5.0.0-4.3.0.0. If these W-IAPs are placed into a cluster running older Instant versions prior to Instant 6.5.1.0-4.3.1.0, the devices will reboot with the Image Sync Fail reason. To resolve this issue, upgrade the existing cluster to minimum Instant 6.5.1.0-4.3.1.0 release, and then add the new W-IAP devices.

This chapter describes the following procedures:

l Setting up Instant Network on page 16

l Provisioning a W-IAP on page 17

l Logging in to the Instant UI on page 19

l Accessing the Instant CLI on page 20

Setting up Instant Network

Before installing a W-IAP:

l Ensure that you have an Ethernet cable of the required length to connect a W-IAP to the home router.

l Ensurethat you have one of the following power sources:

n IEEE 802.3af/at-compliant Power over Ethernet (PoE) source. The PoE source can be any power source

equipment (PSE) switch or a midspan PSE device.

n W-IAP power adapter kit.

Perform the following procedures to set up the Instant network:

1. Connecting a W-IAP on page 16

2. Assigning an IP address to the W-IAP on page 16

Connecting a W-IAP

Based on the type of the power source used, perform one of the following steps to connect a W-IAP to the power source:

l PoE switch—Connect the Ethernet 0 (Enet0) port of the W-IAP to the appropriate port on the PoE switch.

l PoE midspan—Connect the Enet0 port of the W-IAP to the appropriate port on the PoE midspan.

l AC to DC power adapter—Connect the 12V DC power jack socket to the AC to DC power adapter.

W-IAP155P supports PSE for 802.3at-powered device (class 0-4) on one port (E1 or E2), or 802.3af-powered DC IN (Power Socket) on two ports (E1 and E2).

Assigning an IP address to the W-IAP

The W-IAP needs an IP address for network connectivity. When you connect a W-IAP to a network, it receives an IP address from a DHCP server.

To obtain an IP address for a W-IAP:

1. Ensure that the DHCP service is enabled on the network.

2. Connect the Enet0 port of W-IAP to a switch or router using an Ethernet cable.

3. Connect the W-IAP to a power source. The W-IAP receives an IP address provided by the switch or router.

If there is no DHCP service on the network, the W-IAP can be assigned a static IP address. If a static IP is not assigned, the W-IAP obtains an IPautomatically within the 169.254 subnet.

Dell Networking W-Series Instant 6.5.1.0-4.3.1.0 | User Guide Setting up a W-IAP | 16

Assigning a Static IP

To assign a static IP to a W-IAP:

1. Connect a terminal, PC, or workstation running a terminal emulation program to the Console port on the W-IAP.

2. Turn on the W-IAP. An autoboot countdown prompt that allows you to interrupt the normal startup process and access apboot is displayed.

3. Press Enter key before the timer expires. The W-IAP goes into the apboot mode.

4. In the apboot mode, execute the following commands to assign a static IP to the W-IAP.

Hit <Enter> to stop autoboot: 0 apboot> apboot> setenv ipaddr 192.0.2.0 apboot> setenv netmask 255.255.255.0 apboot> setenv gatewayip 192.0.2.2 apboot> save Saving Environment to Flash... Un-Protected 1 sectors .done Erased 1 sectors Writing

Provisioning a W-IAP

This section provides the following information:

l Zero Touch Provisioning of W-IAPs on page 17

l Provisioning W-IAPs through W-AirWave

Zero Touch Provisioning of W-IAPs

Zero Touch Provisioning eliminates the traditional method of deploying and maintaining devices and allows you to provision new devices in your network automatically, without manual intervention. Following are the zero-touch provisioning methods for Instant.

In order for zero-touch provisioning to be successful, the timezone of the W-IAP must be in synchronization with the NTPserver.

To facilitate zero-touch provisioning using the W-AirWave Management Platform (AMP), or Activate, you must configure the firewall and wired infrastructure to either allow the NTP traffic to pool.ntp.org, or provide alternative NTP servers under DHCP options. For more information on configuring an NTPserver, see

NTPServer.

In a scenario where the NTP server is unreachable, the connection between the W-IAP and Activate will fall back to the unsecured status. The NTPclient process running in the back end will continuously attempt to reconnect to the NTPserver until a secure connection is established. The NTPclient process receives a response from the NTP server on successfully establishing a connection and notifies the CLIprocess which runs a series of checks to ensure the NTPserver is reachable.

Connecting to a Provisioning Wi-Fi Network

The W-IAPs boot with factory default configuration and try to provision automatically. If the automatic provisioning is successful, the Instant SSID will not be available. If W-AirWave and Activate are not reachable and the automatic provisioning fails, the Instant SSID becomes availableand the users can connect to a provisioning network by using the Instant SSID.

To connect to a provisioning Wi-Fi network:

1. Ensure that the client is not connected to any wired network.

2. Connect a wireless-enabled client to a provisioning Wi-Fi network: for example, Instant.

3. If the Windows operating system (OS) is used:

a. Click the wireless network connection icon in the system tray. The Wireless Network Connection

window is displayed.

b. Click the Instant network and then click Connect.

4. If the Mac OS system is used:

a. Click the AirPort icon. A list of available Wi-Fi networks is displayed.

b. Click the instant network.

The Instant SSIDs are broadcast in 2.4 GHz only.

W-IAP Cluster

W-IAPs in the same VLAN automatically find each other and form a single functioning network managed by a VC.

Moving a W-IAP from one cluster to another requires a factory reset of the W-IAP.

Disabling the Provisioning Wi-Fi Network

The provisioning network is enabled by default. Instant provides the option to disable the provisioning network through the console port. Use this option only when you do not want the default SSID Instant to be broadcast in your network.

To disable the provisioning network:

1. Connect a terminal, PC, or workstation running a terminal emulation program to the Console port on the W-IAP.

2. Configure the terminal or terminal emulation program to use the following communication settings:

Logging in to the Instant UI

Launch a web browser and enter instant.dell-pcw.com. In the login screen, enter the following credentials:

l Username—admin

l Password—admin

The following figure shows the Login screen:

Figure 1 Login Screen

When you use a provisioning Wi-Fi network to connect to the Internet, all browser requests are directed to the Instant UI. For example, if you enter example.com in the address bar, you are directed to the Instant UI. You can change the default login credentials after the first login.

Regulatory Domains

The IEEE 802.11/b/g/n Wi-Fi networks operate in the 2.4 GHz spectrum and IEEE 802.11a/n operates in the 5 GHz spectrum. The spectrum is divided into channels. The 2.4 GHz spectrum is divided into 14 overlapping, staggered 20 MHz wireless carrier channels. These channels are spaced 5 MHz apart. The 5 GHz spectrum is divided into more channels. The channels that can be used in a particular country vary based on the regulations of that country.

The initial Wi-Fi setup requires you to specify the country code for the country in which the Instant operates. This configuration sets the regulatory domain for the radio frequencies that the W-IAPs use. Within the regulated transmission spectrum, a high-throughput 802.11ac, 802.11a, 802.11b/g, or 802.11n radio setting can be configured. The available 20 MHz, 40 MHz, or 80 MHz channels are dependent on the specified country code.

You cannot change the country code for the W-IAPs in the restricted regulatory domains such as US or Japan for most of the W-IAP models. For W-IAP-RW variants, you can select from the list of supported regulatory domains. If the supported country code is not in the list, contact your Dell Support team to know if the required country code is supported and obtain the software that supports the required country code.

19 | Setting up a W-IAP Dell Networking W-Series Instant 6.5.1.0-4.3.1.0 | User Guide

Improper country code assignments can disrupt wireless transmissions. Most countries impose penalties and sanctions on operators of wireless networks with devices set to improper country codes.

To view the country code information, run the show country-codes command.

Specifying Country Code

This procedure is applicable only to the W-IAP-RW variants. Skip this step if you are installing W-IAP in the United States and Japan.

The Country Code window is displayed for the W-IAP-RW variants when you log in to the W-IAP UI for the first time. The Please Specify the Country Code drop-down list displays only the supported country codes. If the W-IAP cluster consists of multiple W-IAP platforms, the country codes supported by the master W-IAP is displayed for all other W-IAPs in the cluster. Select a country code from the list and click OK. The W-IAP operates in the selected country code domain.

Figure 2 Specifying a Country Code

You can also view the list of supported country codes for the W-IAP-RW variants using the show countrycodes command.

Accessing the Instant CLI

Instant supports the use of Command Line Interface (CLI) for scripting purposes. When you make configuration changes on a master W-IAP in the CLI, all associated W-IAPs in the cluster inherit these changes and subsequently update their configurations. By default, you can access the CLI from the serial port or from an SSH session. You must explicitly enable Telnet access on the W-IAP to access the CLI through a Telnet session.

For information on enabling SSH and Telnet access to the W-IAP CLI, see Terminal access on page 60.

Connecting to a CLI Session

On connecting to a CLI session, the system displays its host name followed by the login prompt. Use the administrator credentials to start a CLI session. For example:

User: admin

If the login is successful, the privileged command mode is enabled and a command prompt is displayed. For example:

(Instant AP)#

The privileged EXEC mode provides access to show, clear, ping, traceroute, and commit commands. The configuration commands are available in the config mode. To move from Privileged EXEC mode to the Configuration mode, enter the following command at the command prompt:

(Instant AP)# configure terminal

Dell Networking W-Series Instant 6.5.1.0-4.3.1.0 | User Guide Setting up a W-IAP | 20

The configure terminal command allows you to enter the basic configuration mode and the command prompt is displayed as follows:

(Instant AP)(config)#

The Instant CLI allows CLI scripting in several other subcommand modes to allow the users to configure individual interfaces, SSIDs, access rules, and security settings.

You can use the question mark (?) to view the commands available in a privileged EXEC mode, configuration mode, or subcommand mode.

Although automatic completion is supported for some commands such as configure terminal, the complete exit and end commands must be entered at command prompt.

Applying Configuration Changes

Each command processed by the VC is applied on all the slaves in a cluster. The changes configured in a CLI session are saved in the CLI context. The CLI does not support the configuration data exceeding the 4K buffer size in a CLI session. Therefore, it is recommended that you configure fewer changes at a time and apply the changes at regular intervals.

To apply and save the configuration changes at regular intervals, execute the following command in the privileged EXEC mode:

(Instant AP)# commit apply

To apply the configuration changes to the cluster without saving the configuration, execute the following command in the privileged EXEC mode:

(Instant AP)# commit apply no-save

To view the changes that are yet to be applied, execute the following command in the privileged EXEC mode:

(Instant AP)# show uncommitted-config

To revert to the earlier configuration, execute the following command in the privileged EXEC mode.

(Instant AP)# commit revert

Example:

To apply and view the configuration changes:

(Instant AP)(config)# rf dot11a-radio-profile (Instant AP)(RF dot11a Radio Profile)# beacon-interval 200 (Instant AP)(RF dot11a Radio Profile)# no legacy-mode (Instant AP)(RF dot11a Radio Profile)# dot11h (Instant AP)(RF dot11a Radio Profile)# interference-immunity 3 (Instant AP)(RF dot11a Radio Profile)# csa-count 2 (Instant AP)(RF dot11a Radio Profile)# spectrum-monitor (Instant AP)(RF dot11a Radio Profile)# end

(Instant AP)# show uncommitted-config

rf dot11a-radio-profile beacon-interval 200 no legacy-mode dot11h interference-immunity 3 csa-count 2 spectrum-monitor

(Instant AP)# commit apply

Using Sequence-Sensitive Commands

The Instant CLI does not support positioning or precedence of sequence-sensitive commands. Therefore, it is recommended that you remove the existing configuration before adding or modifying the configuration details for sequence-sensitive commands. You can either delete an existing profile or remove a specific configuration by using the no… commands.

The following table lists the sequence-sensitive commands and the corresponding no commands to remove the configuration:

Banner and Loginsession Configuration using CLI

Starting from Instant 6.5.0.0-4.3.0.0, the Banner and Loginsession Configuration feature is introduced in the W-IAP, wherein the text banner can be displayed at the login prompt when users are on a management (Telnet or SSH) session of the CLI, and the management session can remain active even when there is no user activity involved.

The banner command defines a text banner to be displayed at the login prompt of a CLI. Instant supports up to 16 lines text, and each line accepts a maximum of 255 characters including spaces.

To configure a banner:

(Instant AP)(config)# banner motd <motd_text>

Example of a text banner configuration:

(Instant AP)(config)# banner motd "######welcome to login instant###########" (Instant AP)(config)# banner motd "####please start to input admin and password#########" (Instant AP)(config)# banner motd "###Don't leak the password###" (Instant AP)(config)# end (Instant AP)# commit apply

To display the banner:

(Instant AP)# show banner

Dell Networking W-Series Instant 6.5.1.0-4.3.1.0 | User Guide Setting up a W-IAP | 22

The loginsession command configures the management session (Telnet or SSH) to remain active without any user activity.

To define a timeout interval:

(Instant AP) (config) #loginsession timeout <val>

<val> can be any number of minutes from 5 to 60, or any number of seconds from 1 to 3600. You can also specify a timeout value of 0 to disable CLI session timeouts. The users must re-login to the W-IAP after the session times out. The session does not time out when the value is set to 0.

Chapter 4

Automatic Retrieval of Configuration

This chapter provides the following information:

l Managed Mode Operations on page 24

l Prerequisites on page 24

l Configuring Managed Mode Parameters on page 25

l Verifying the Configuration on page 26

Managed Mode Operations

W-IAPs support managed mode operations to retrieve the configuration file from a server through the File Transfer Protocol (FTP) or FTP over Secure Sockets Layer (FTPS), and automatically update the W-IAP configuration.

The server details for retrieving configuration files are stored in the basic configuration of the W-IAPs. The basic configuration of a W-IAP includes settings specific to a W-IAP, for example, host name, static IP, and radio configuration settings. When a W-IAP boots up, it performs a GET operation to retrieve the configuration (.cfg) file from the associated server using the specified download method.

After the initial configuration is applied to the W-IAPs, the configuration can bechanged at any point. You can configure a polling mechanism to fetch the latest configuration by using an FTP or FTPS client periodically. If the remote configuration is different from the one running on the W-IAP and if a difference in the configuration file is detected by the W-IAP, the new configuration is applied. At any given time, W-IAPs can fetch only one configuration file, which may include the configuration details specific to a W-IAP. For configuring polling mechanism and downloading configuration files, the users are required to provide credentials (username and password). However, if automatic mode is enabled, the user credentials required to fetch the configuration file areautomatically generated. To enable automatic configuration of the W-IAPs, configure the managed mode command parameters.

Prerequisites

Perform the following checks before configuring the managed mode command parameters:

l Ensure that the W-IAP is running Instant 6.2.1.0-3.4 or later versions.

l When the W-IAPs are in the managed mode, ensure that the W-IAPs are not managed by W-AirWave.
