This release of Extreme Networks A3 adds several features and includes several bug fixes.
The upgrade process is a very CPU intensive task. Before upgrading, make sure that each of the cluster node has sufficient idle CPU cycles. If messages similar to those below are displayed in the GUI window after upgrade, then either configuration files could not be backed up within the 2 minute window or configuration changes occurred while the system was trying to perform a backup. If this is the case, you will need to try again with the system in a more quiescent state.
Gathering cluster information... done!
Checking health of cluster nodes... done!
Backing up cluster data... error at <IP address>
Cluster update was unsuccessful.
Changes in Behavior or Appearance
This version of A3 features the following changes in behavior and appearance:
sensitive help has been added to A3. It works in two ways:
|A3-2600||For EXOS switches, the Clients list now correctly reports "Device Port Description" colummn as "ifAlias (ifName)" or "ifName" if "ifAlias is empty.|
|A3-2901||An LDAP Browser authentication option has been added to the Tools > Authentication menu.|
|A3-2911||The following options are not supported by VOSS devices and should
not be enabled:
|A3-2921||A Lite version of DOWNLOAD TECH DATA is now available, for use under direction by Extreme Networks personnel. When Lite Mode is selected the tech data bundle will only include the configuration files and any current and previous day log files. It is intended to package only those files which are relevant for troubleshooting more recently observed issues.|
|A3-2960||A Monit tool has been added to the Tools > Network Tools menu. It is a utility for managing and monitoring A3 processes, files, directories and file systems. Monit conducts automatic maintenance and repair and can execute meaningful actions in error situations. Monit is automatically disabled during an upgrade and will need to be manually re-enabled after the upgrade completes.|
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:
|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 Extreme Networks 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.|
|When you remove a node from an A3 cluster, it can neither rejoin the cluster, nor function as a standalone and must be discarded.|
The following are known issues in this release of Extreme Networks A3:
|Prior to upgrading from a pre-V3.x version, Extreme Networks 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 ExtremeCloud IQ 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 can be necessary if an administrator can not log into the A3 cloud GUI from HiveManager.|
|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.|
|A3-99||When creating an Active Directory entry, the identifier must be alpha-numeric with no spaces.|
|A3-125||After a successful Join AD Domain, a spurious "An error occurred while contacting the server" can be shown.|
|A3-910||If the initial setup is not completed by the time the current DHCP lease expires, A3 loses its IP address.|
|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. Enter any value.|
|A3-1180||Authentication tests do not change prompts to be applicable with the Authentication Source. Enter appropriate values into the Username and Password fields.|
|A3-1277||When two SSID filters are used in a single connection profile, 802.1x logins fail.|
|A3-2249||Administrative rules cannot be configured for EAP-TLS authentication.|
|A3-2510||A3 servers with prior versions can be allowed to join a cluster.|
|A3-2579||The Captive Portal redirection delay can be too short. The redirection can have occurred in spite of an error message.|
|A3-2624||There is no way to delete a Role in the A3 GUI.|
|A3-2653||Backup from the Backup & Restore page must be done on the primary A3 node.|
|A3-2722||The copy to clipboard option for the Tech Data logs does not work.|
|A3-2748||The Restart services popup can remain open after the operation is complete.|
|A3-2785||When using the graphics Network View, hovering over an A3 server can show "PacketFence" instead of A3.|
|A3-2933||The Tools top level menu is not available when the A3 GUI is access from ExtremeCloud IQ.|
The following issues have been addressed in this release of Extreme Networks A3:
|A3-2661||A CA certificate path is no longer required when configuring a provisioner.|
|A3-2871||The dNSHostName attribute has been added Authentication Sources > AD > Search attributes.|
|A3-2833||A disconnected wireless client entry can now be deleted from the Clients page.|
