New Features and Enhancements

The following new features and enhancements were added in release 3.0.0 of Extreme Networks A3:

This version of A3 features the following changes in behavior and appearance:

A3-2316: Online Help Now Available:

The A3 Help function can be invoked from the A3 GUI via the button on the toolbar at the top of the page. The topics available includes: Release Notes (this document), Hot Topics, GUI Help, Theory of Operation, Installation Guide, and Network Devices Configuration Guide.

A3-1555: Enhanced GUI:

The A3 GUI has been enhanced with modern controls. All functionality has been maintained, albeit with different usage. Refer to the online help for more details.

A3-tbd: Change in terminology for nodes and violations:

The term Nodes is replaced with Clients, both in the top level menu and throughout the GUI. The term Violations is replaced with Security Events.

A3-1856: HiveManager has a new A3 > Inventory menu item that lists all A3 instances that are associated with a Cloud account. Clicking on one of the instances allows A3 instances to be managed and configured from the cloud. The cloud-based A3 GUI duplicates the A3-resident GUI with just a few exceptions.

A3-1555: A3 now provides optimized facilities for requesting and installing certificates for use with HTTPS and RADIUS. CSRs (Certificate Signing Requests) can be generated and sent to commercial certificate authorities; returned certificates are pasted into GUI forms. An interface to Let's Encrypt (https://letsencrypt.org/) is provided for generation of a free 90-day certificate.

A3-2185: A3 OVA images now calls for the Extreme Networks recommended 16 GB of memory.

A3-2040: When installing an A3 instance, clustering mode is automatically enabled. This allows later addition of A3 servers to the cluster.

A3-2153: A3 web services previously accessed through Configuration > Integration are no longer available.

Software Limitations

Limitations are not necessarily software issues, but might affect workflow, and are presented here for your reference and consideration.

The following are known software limitations in this release of Extreme Networks A3:

Description
When setting up a cluster, only one node should be added to the cluster at a time. Additional nodes should only be added after the previous join process has completed.
When linking to an Aerohive cloud account, reports only include data from that moment onward, and do not include historical data prior to linking.
You cannot change the management network interface of an A3 cluster using the UI after initial configuration. Ensure the accuracy of your setup when you initially configure the management network interface.
Administrators might not be able to log in to A3 if the clock on the A3 system is not accurate.
After adding an Active Directory domain, always restart A3 services in the following order to prevent service dependency issues: radiusd, radsniff, netdata, pfstat.
In a cluster environment, all configuration must be performed through the cluster's VIP address.
When you remove a node from an A3 cluster, it can neither rejoin the cluster, nor function as a standalone and must be discarded.

Known Issues

There are no known issues in this release.

The following are known issues in this release of Extreme Networks A3:

ID Description
  Prior to upgrading, Aerohive recommends powering down your server or cluster members. If the RAM associated with the A3 VM still uses the old default of 8 GB, it should be increased to 16 GB.
  This issue pertains to A3 instances in which the A3 server or cluster was connected to HiveManager prior to the upgrade. After performing the upgrade, the administrator should log into the local A3 GUI and unlink the server or cluster from Hive Manager. The setting for this is at Configuration > System Configuration > Cloud Integration. After a moment, the server can be relinked to the HiveManager account. This may be necessary if an administrator can not log into the A3 cloud GUI from HiveManager.
A3-1224 The A3 Tools page does not appear properly on some macOS versions.
A3-1179 A3 sometimes prompts the admin to enter a user name and password when performing authentication tests using sources that do not require this type of authentication.
A3-920 When an admin restarts an entire cluster, one of the cluster node databases sometimes cannot start properly.
A3-910 If the initial setup is not completed by the time the current DHCP lease expires, A3 loses its IP address.
A3-860 When an admin attempts to restore a cluster from VM snapshots, A3 sometimes does not start properly.
A3-857 A3 does not start properly after an admin removes an active node from a multiple-node cluster that has an inactive node.
A3-1691 DNS Settings configured using the UI are overwritten by new adding new physical interfaces through the VM.
  Profile installation on macOS requires the captive web portal to be opened using the Safari browser.
  The Network Detection feature of the Captive Portal is always enabled, regardless of the setting of the switch in Configuration > Advanced Access Configuration > Captive Portal.
A3-2332 When a service is restarted in a cluster, it must be individually started on all members. GUIs must be opened for all cluster members, although administration is occurring on the Master.
