Chapter 1 Overview Congratulations on successfully installing Dell Networking W-AirWave 8.2.x! So where do you go from here? This document is designed to help you with your initial setup. It also provides information on common configuration options and daily monitoring practices. Refer to the following sections: l "Initial Setup" on page 5 l "Common Configuration Options" on page 19 l "Monitoring Practices" on page 31 Initial Setup Dell Networking W-AirWave 8.2.
Figure 1: Device Setup > Add Page Illustration 2. Select Add. The Device Communications and Location sections appear (see Figure 2). 6 | Overview Dell Networking W-AirWave 8.2.
Figure 2: Device Setup > Add > Device Communications and Location Sections 3. Complete the Device Communications and Location settings for the new device. Settings can differ from device to device based on the type of device and the features that the device supports. In several cases, the default values in the Device Communication page from any given device are derived from the Device Setup > Communication page. 4. In the Location field, select the appropriate group and folder for the device. 5.
Discovering New Devices In addition to manually adding devices, devices connected to your network can automatically be discovered and added. AirWave performs device discovery using the following methods. These methods are described in greater detail in the Dell Networking W-AirWave 8.2.x User Guide. l SNMP/HTTP Discovery Scanning – This is the primary method for discovering devices. Refer to "Configuring and Running a Scan Set" on page 8 for information about how to utilize this feature.
d. Select Add when you are finished, and repeat these steps for each scan set that you want to create. Discovered devices use the default credentials configured on the Device Setup > Communication page for each vendor-specific device. Refer to "How Do I Define Credentials for Devices that Communicate with AirWave?" on page 15 for more information. 4. Running a scan set. a. Navigate to the Device Setup > Discover page and select the check boxes for each scan to run. b. Click Scan. c.
Put devices in Monitory Only + Firmware Upgrades mode when they are added to a newly established device group. This avoids overwriting any important existing configuration settings. 5. Click Add. You can go to the APs/Devices > List page and select the folder that contains the newly added devices. This enables you to verify that the devices have been properly assigned.
l SNMPv3 user name l Telnet user name l Telnet password l Enable password l SNMP port You can download and customize a file. 1. To import a CSV file, go to the Device Setup > Add page. 2. Click the Import Devices via CSV link. The Upload a list of devices page displays. See Figure 4. Figure 4: Device Setup > Add > Import Devices via CSV Page Illustration 3. Select a group and folder into which to import the list of devices. 4. Click Choose File and select the CSV list file on your computer. 5.
Select the pencil icon next to an interface, to select to be non-monitored or monitored as an interface. AirWave collects this information and displays it on the APs/Devices > Monitor page in the Interface section. AirWave supports MIB-II interfaces and polls in/out byte counts for up to two interfaces. AirWave also monitors sysUptime. Adding a Dell Controller Dell Networking W-Series controllers can be discovered during a scan or can be added manually.
You can add up to four addresses. Adding as a Trap Host To ensure the AirWave server is defined as a trap host, access the command line interface of each controller (master and local), enter enable mode, and issue the following commands: (Controller-Name) # configure terminal Enter Configuration commands, one per line.
l Security settings - VLANs, WEP, 802.1X, ACLs, and so forth l Radio settings - data rates, fragmentation threshold, RTS threshold, DTIM, preamble, and so forth. When configuration changes are applied at a group level, they are assigned automatically to every device within that group. These changes must be applied to every device while in Managed mode. When you first configure AirWave, only a group named Access Points is available.
How Do I Define Credentials for Devices that Communicate with AirWave? On the Device Setup > Communication page, you can configure AirWave to communicate with your vendorspecific devices, and you can set SNMP polling information. The configuration defines the default credentials for future devices; it does not impact existing devices. See Figure 5.
Community strings and shared secrets must have read-write access in order for AirWave to configure the devices. Without read-write access, AirWave can monitor the devices only; it cannot apply any configuration changes. 2. Specify SNMP Settings. a. Specify an SNMP Timeout value. This is the number of seconds that AirWave will wait for a response from a device after sending an SNMP request, so a smaller number is more ideal. b. Enter a value for SNMP Retries.
4. Click Audit. The configuration state changes from Mismatched to Verifying. Note that this process can take several minutes to complete. After the audit is complete, the configuration state should change from Verifying to Good. Importing Group Settings to Resolve Mismatches Some mismatches can occur because the controller's group settings do not match the desired configuration. In this case, importing group settings can resolve the mismatch. 1.

Chapter 2 Common Configuration Options This section describes common configuration options for triggers, reports, and alerts that you might use on a daily basis.
l Up - When a device comes up, its Device Down alerts are acknowledged. l Up and Down - Like above, and in addition if the device goes down, it's Device Up alerts are acknowledged. Alert Suppression It's important to understand the "Suppress Until Acknowledged" setting for triggers. l If suppression is set to No, then AirWave will send out an alert every time it detects the symptom. For example, if an AP were down, we would send an alert every time we poll for Thin AP Status, typically every 5 minutes.
Device Down Trigger Since there is a different severity when a controller goes down versus when an AP goes down versus a switch, we recommend to set up three separate device down triggers, one for each class of device. Figure 7 shows an example of a Controller Down Trigger. Figure 7: Controller Down Trigger Device Up Trigger Adding a Device Up trigger with the Auto Acknowledge feature enabled helps with the workflow by acknowledging Device Down alerts when devices come back up.
Figure 9: Channel Utilization Trigger Rogue Reclassified Trigger Use this trigger for things that are classified as rogue or greater. Connected Clients Trigger This is sometimes called the "stolen iPad" trigger. If a device is missing, set up a trigger with its MAC address, and this will send an alert whenever the device is seen on the network. For some customers, disabling alert suppression makes sense for this trigger.
Figure 10: Client RADIUS Authentication Issues Trigger All Triggers The following triggers are available in AirWave 8.2.5.1.
Which Reports Should I Use? AirWave includes a powerful, industry leading reporting feature, with customizable reports on devices, clients, the wireless and wired network, and security. This section describes some of the best practices in using reports. This section includes the following topics: l "Creating Report Definitions" on page 24 l "Report Types" on page 25 l "Recommended Reports" on page 30 Creating Report Definitions You can use the following features when defining reports.
Report Types AirWave has multiple predefined reports that contain one or more sections of data, (also called widgets). The most commonly used reports are the Dell License, Device Summary, Inventory, Client Details, AppRF, and RF Health reports . You can also create a custom report by combining individual widgets from multiple report types.

Chapter 3 Monitoring Practices With AirWave, you can monitor devices on your network with the click of a button and see real-time statistics as well as historical information. Diagnostic summaries highlight anomalies and situations that can affect end-user network performance. AirWave includes monitoring views designed to aggregate critical information for the help desk, as well as the high-end monitoring functions network engineers need.
Figure 12: APs/Devices > List (partial view) Monitoring Data for Wired Devices (Routers and Switches) The monitoring page for routers and switches includes basic device information at the top. Beneath that are graphs that display the number of clients and their usage. A menu in each graph allows you to change the graph to view CPU and Memory utilization data. All managed wired devices include an Interfaces subtab, as shown in Figure 13. 32 | Monitoring Practices Dell Networking W-AirWave 8.2.
Figure 13: APs/Devices > Interfaces Page for Wired Devices (partial view) . The top of the Interfaces page includes a summary of all interfaces. In the case of stacked switches, the master includes the interfaces of all the members, including its own. The physical and virtual interfaces are displayed in separate tables, labeled Physical Interfaces and Virtual Interfaces. VLANs are listed below the interface. The Interfaces page for AirMesh APs includes VLANs as part of the Virtual Interfaces.
Figure 14: Monitoring Page Top-level Data Common to all Device Types The alert summary and recent events sections are the same regardless of the device type, and these sections appear toward the bottom of these pages. A link to the Audit Log is available on the bottom of this page. A portion of this page is shown in Figure 15.
Figure 16: Interface Monitoring Page for a Wired Device An Interface Monitoring page has three sections. The Interface Information table at the top of the page displays specific details about the interface, the Usage and Interface Frame Counters graphs appear in the middle of the page, and the Connected Clients table at the bottom of the page lists the user name, role, MAC address, association time and signal quality for any connected clients.
Figure 17: Drill Down to View Client Data Click any user name in the Clients popup window to open the Clients > Diagnostics page and view additional detailed information about the selected client. Viewing Syslog Messages AirWave allows you to specify an external syslog server for storing audit and system events. After the external server is set up, everything written to the AirWave Event Log and audit logs will be sent to a specified syslog server.
