What’s New in This Release

Authentication

Authentication with LDAP

AMP users can be authenticated using LDAP in addition to TACACS and RADIUS. This option is

configurable on the AMP Setup > Authentication page. When enabled, users can specify the primary and

secondary host name and port servers, the connection type, the key and role attributes, and the bind

password. This implementation also supports verification of the server's certificate when the Connection

Type is specified as start-tls. The server certificate can be added on the Device Setup > Certificates

page. After this is added, users can specify optional or require in the Verify Server Certificate drop

down menu.

More information about LDAP authentication can be found in RFC 4513.

Authentication Priority

Local and remote authentication priority order is now user selectable. If Local is selected, then remote

authentication will only be attempted if the user is not present. If Remote is selected, then the local

database is searched if authentication on the remote server fails. The order of remote authentication is

RADIUS first, followed by TACACS, and finally LDAP.

Recurring Configuration Changes

Users now have the option to schedule configuration options (such as disabling radios) as recurring.

Scheduling provides a way for you to inform users on your network of upcoming down-time and helps with

planning tasks such as upgrading. Click on Save and Apply, Import Settings, or Reboot on the APs/

Devices > Manage (for device maintenance) or on the Groups > Basic page (for group maintenance) to

view a prompt for setting the changes as recurring.

Configurable Client Diagnostics

The thresholds used for Client diagnostics are now configurable. Select a connected client from the APs/

Devices page to view the client. Navigate to the Diagnostics tab, and click the Thresholds button on the

lower-right corner of the page to adjust the threshold values for Good and Fair. The new values will be

applied globally to diagnostic views for all other AirWave user roles.

PAGE 2
Suppressing Alerts if the Upstream Device is Down A new setting available on the Device Down trigger suppresses alerts if the upstream device is down. The behavior of existing triggers is preserved upon upgrade to 7.5, but the setting is enabled by default for new triggers. AirWave users can combine the new setting with the Minutes Down threshold to allow enough time for AirWave to determine the state of the upstream device.
PAGE 3
New Diagnostics Graph The 7.5.4 release introduces a new graph on the System > Performance page. The graph shows the current number of Web server connections and the current number of database connections over a period of time. This new graph provides better visibility into errors that may occur due to Web server connection limits.
PAGE 4
 When e-mailing an Uptime Report, users can now select whether the sort order should be based on the lowest uptime or the highest.  An option is provided under AMP Setup > General > Additional AMP Services to configure a collection of syslog messages and traps. Customers who are concerned about the effect that syslog collection may have on performance of their AirWave server can either adjust how their controllers are configured to send data or they can disable processing the data in AirWave.
PAGE 5
Aruba AirMesh Enhancements AirMesh enhancements for 7.5 fall into one of two categories: Monitoring and Configuration. AirMesh Monitoring  New AirMesh products were released in March 2012 with the new bootloader “APBoot ” label, which is consistent with the other Aruba APs. AirWave helps to identify this new from the old SKUs (such as “Redboot ”) by displaying the bootloader information now on the APs/Devices > Monitor and APs/Devices > List pages as well as in the Inventory Report.

Table 12 Known Issues in AirWave 7.5.0 (Continued) ID Description DE11264 A VisualRF floor plan may occasionally show multiple device types with the same MAC address. DE11309 In VisualRF, be sure to drag new building icons away from the very upper-left corner of the canvas. Failing to do so can cause inconsistent right-click menus to display. Specifically, you may right-click on the building and see options specific for the background/canvas rather than for the building.
PAGE 20
Table 12 Known Issues in AirWave 7.5.0 (Continued) ID Description DE11986 In some cases, Device events (traps) can correlate to a client rather than an AP. This can occur, for example, when a RAP-2 device is plugged into a RAP-5 device. In this case, the RAP-2 has its own clients, but will now also appear as a wired client of the RAP-5.
