ExtremeCloud IQ Site Engine 25.08.11 Release Notes

A PDF copy of these release notes can be found here.

ExtremeCloud IQ Site Engine includes all the features and functionality of Extreme Management Center as well as issues that have been resolved and configuration changes for this release.

If you are an existing Extreme Management Center customer, contact your representative to have your Extreme Management Center license migrated to an ExtremeCloud IQ Site Engine license. The ExtremeCloud IQ Site Engine license also includes licensing for ExtremeAnalytics.

IMPORTANT:

For upgrade and installation requirements, as well as configuration considerations, see ExtremeCloud IQ Site Engine Configuration and Requirements.
ExtremeCloud IQ Site Engine version 25.08.11 consumes licenses from Extreme Platform ONE or ExtremeCloud IQ in a connected deployment mode or from a license file in air gap deployment mode. ExtremeCloud IQ Site Engine is a subscription-based -only licensing model. Existing NMS licenses do not provide access to ExtremeCloud IQ Site Engine. You can view the status of your license by accessing Administration > Licenses after the installation is complete.
ExtremeCloud IQ Site Engine is not compatible with an ExtremeCloud IQ Connect level account. You must use a commercial or trial subscription.
ExtremeCloud IQ Site Engine is not compatible with ExtremeCloud IQ HIQ. You must use a standard VIQ or MSP account.
For the information shared between ExtremeCloud IQ Site Engine and ExtremeCloud IQ , see ExtremeCloud IQ Connection.

For information regarding the features supported by specific devices, see the Firmware Support Matrix. Version 25.08.11 of ExtremeCloud IQ Site Engine supports the devices listed in the matrix.

Devices that do not have serial numbers or MAC addresses in Extreme Management Center must be rediscovered after you upgrade to ExtremeCloud IQ Site Engine before they can be onboarded to ExtremeCloud IQ.

Connected mode only - If your number of devices exceeds your licenses available, ExtremeCloud IQ Site Engine transitions to a license violation state and your access to ExtremeCloud IQ Site Engine is locked. To resolve the license shortage you need to access the Extreme Networks portal or ExtremeCloud IQ to evaluate the quantities of available Pilot and Navigator licenses versus the number of licenses required by ExtremeCloud IQ Site Engine.

Licensing Changes

The following sections describe licensing changes in ExtremeCloud IQ Site Engine software releases.

Version 25.02.10

Starting in ExtremeCloud IQ Site Engine version 25.02.10 the new Extreme Platform ONE subscriptions are recognized if ExtremeCloud IQ Site Engine is onboarded to ExtremeCloud IQ or Extreme Platform ONE.

Version 23.02.10

Starting in ExtremeCloud IQ Site Engine version 23.02.10 each stack member consumes a license in connected mode. In connected mode, ExtremeCloud IQ Site Engine now reports stack members to ExtremeCloud IQ.

Version 21.09.10

For users upgrading from Extreme Management Center to ExtremeCloud IQ Site Engine, note that the XIQ-NAC subscription must be used instead of IA-ES- license.

Installation, Upgrade, and Configuration Changes

Installation Information

For license requirements for ExtremeCloud IQ Site Engine and devices, see Licensing.

For complete installation instructions, see ExtremeCloud IQ Site Engine Suite Installation.

Upgrading Without an Internet Connection

If your Linux system requires an operating system upgrade, you are prompted to upgrade using either an internet connection or locally (without an internet connection) if no additional Ubuntu packages need to be installed.

!!! ATTENTION !!! 

We can attempt to upgrade the OS without using the internet if there were no extra Ubuntu packages installed. If there were extraneous packages installed, the upgrade will fail with this method. 

Do you want to attempt a local in-place upgrade of the OS and reboot when complete? (Y/n)

Custom FlexViews

When reinstalling ExtremeCloud IQ Site Engine Console, the installation program saves copies of any FlexViews you created or modified in the <install directory>\.installer\backup\current\appdata\System\FlexViews folder.

If you are deploying FlexViews via the ExtremeCloud IQ Site Engine server, save them in the appdata\VendorProfiles\Stage\MyVendorProfile\FlexViews\My FlexViews folder.

Custom MIBs and Images

If you are deploying MIBs via the ExtremeCloud IQ Site Engine server, they are saved in the appdata\VendorProfiles\Stage\MyVendorProfile\MIBs\ folder.

If you are deploying device images (pictures) via the ExtremeCloud IQ Site Engine server, they are saved in the appdata\VendorProfiles\Stage\MyVendorProfile\Images\ folder.

Important Upgrade Information

A special MySQL to PostgreSQL Data Migration (For Upgrades from ExtremeCloud IQ Site Engine 24.2 to 24.7 and later) is required to upgrade ExtremeCloud IQ Site Engine from versions older than 24.07. The minimum version to upgrade Analytics Engines and Access Control Engines is 24.02.13.

NOTE:

ExtremeCloud IQ Site Engine Version 25.08.11 contains an OS upgrade. Internet connectivity is required to download custom packages.

The installer prompts "Do you want to use the Internet to perform the OS upgrade?". The offline upgrade path is supported when no custom packages are installed (answer N). The online upgrade is required when custom packages are manually installed (answer Y). An online upgrade is recommended when an online upgrade was used previously, however there is a risk of session timeout due to 15 minutes of screen inactivity.

To upgrade Access Control Engines and Application Analytics Engines you can use the directive --keepalive to decrease the chance of a session expiry timeout from 15 minutes of no screen activity.

From Version (currently running)	To Version (next step in upgrade path)
ExtremeCloud IQ Site Engine 24.07.x, 24.10.x. 25.02.x, 25.05.x	ExtremeCloud IQ Site Engine 25.08
ExtremeCloud IQ Site Engine 24.02.x	Fresh installation of ExtremeCloud IQ Site Engine 25.08 and follow the MySQL to PostgreSQL Data Migration (For Upgrades from ExtremeCloud IQ Site Engine 24.2 to 24.7 and later)
Application Analytics Engine, Access Control Engine 24.02.15	Application Analytics Engine, Access Control Engine 25.08
ExtremeCloud IQ Site Engine 23.04.12, 23.07.x, 23.11.x, 24.02.x	ExtremeCloud IQ Site Engine 24.02.15
ExtremeCloud IQ Site Engine 21.x, 22.x, 23.2.x 23.04.10, 23.04.11	ExtremeCloud IQ Site Engine 23.04.12
Extreme Management Center version 8.5.7	ExtremeCloud IQ Site Engine 24.02.15
Extreme Management Center version 8.2.x to 8.5.6	Extreme Management Center 8.5.7
Extreme Management Center version 8.0.x to 8.1.x	Extreme Management Center 8.3.3.11
NetSight version 7.1.4.1	Extreme Management Center 8.3.3.11
NetSight version 7.x	NetSight 7.1.4.1
NetSight version 6.3.0.186	NetSight 7.1.4.1
NetSight version 6.x	NetSight 6.3.0.186

	IMPORTANT:	A backup (Administration > Backup/Restore) of the database must be performed prior to the upgrade and saved to a safe location.

If you use LDAPS with a Fully Qualified Domain Name (FQDN) in the URL to authorize a user to the OneView, then ExtremeCloud IQ Site Engine presents the Server Certificate (located in Administration > Certificates > Server Certificate Information) to the LDAPS server. If the LDAPS server presents a certificate that does not match the LDAPS URL, then the certificate is rejected with the error “Certificate Unknown”.

The best practice is to use a trusted certificate if the LDAPS URL is defined with FQDN, otherwise the LDAPS server might not accept the LDAPs connection. The alternative option is to use an IP address in the LDAPS URL instead of FQDN.

Important Upgrade Considerations

If your network is using ExtremeAnalytics or ExtremeControl engines, or another add-on feature, you must first perform the ExtremeCloud IQ Site Engine upgrade to version 25.08.11 and then upgrade the feature.
To upgrade Traffic Sensor from version 21.x, a fresh installation is recommended. If the fresh installation cannot be used, then please check Knowledge Base for a special procedure.
If the online upgrade fails due to an Internet connectivity issue, fix the connectivity issue and rerun the upgrade.

IMPORTANT:

When performing an upgrade, be sure to back up the database prior to performing the upgrade, and save it to a safe location. Use the Administration > Backup/Restore tab to perform the backup.

When upgrading the ExtremeCloud IQ Site Engine server, ExtremeAnalyticsengine, or ExtremeControlengine to version 25.08.11, ensure the DNS server IP address is correctly configured.
When upgrading to ExtremeCloud IQ Site Engine version 25.08.11, if you adjusted the ExtremeCloud IQ Site Engine memory settings and want them to be saved on upgrade, a flag (-DcustomMemory) needs to be added to the /usr/local/Extreme_Networks/NetSight/services/nsserver.cfg file.

For example:
-Xms12g -Xmx24g -XX:HeapDumpPath=../../nsdump.hprof -XX:+HeapDumpOnOutOfMemoryError -XX:MetaspaceSize=128m -DcustomMemory

License Renewal

Upgrading to ExtremeCloud IQ Site Engine version 25.08.11 requires you to transition from perpetual to subscription-based license model. Existing NMS licenses do not provide access to ExtremeCloud IQ Site Engine. If your perpetual licenses were not transitioned to subscription-based licenses, contact your Extreme Networks Representative for assistance.

Free Space Consideration

When upgrading to ExtremeCloud IQ Site Engine version 25.08.11, a minimum of 15 GB of free disk space is required on the ExtremeCloud IQ Site Engine server

To increase the amount of free disk space on the ExtremeCloud IQ Site Engine server, perform the following:

Decrease the number of ExtremeCloud IQ Site Engine backups (by default, saved in the /usr/local/Extreme_Networks/NetSight/backup directory).
Decrease the Data Persistence settings (Administration > Options > Access Control > Data Persistence).
Remove unnecessary archives (Network > Archives).
Delete the files in the <installation directory>/NetSight/.installer directory.

Site Discover Consideration

Discovering devices via the Site tab using a Range, Subnet, or Seed discover might not successfully add all expected devices. To correct the issue, increase the Length of SNMP Timeout value on the Administration > Options > Site tab in the Discover First SNMP Request section.

ExtremeAnalytics Upgrade Information

Enabling or disabling the disk flow export feature might cause enforce operations to time out. Enforcing again resolves the issue.

When you delete an ExtremeXOS/Switch Engine device that is configured as a flow source via the Flow Sources table of the
Analytics > Configuration > Engines > Configuration tab from the Devices list on the Network > Devices tab, an error message is generated in the server.log. The message does not warn you that the device is in use as a flow source. Adding the device back in the Devices list on the Network > Devices tab or removing the device from the Flow Source table fixes the issue.

The Flow Sources table on the Analytics > Configuration > engine > Configuration tab may take a few minutes to load.

ExtremeControl Version 8.0 and later

Beginning in version 8.0, ExtremeControl may fail to join Active Directory when accessing as a Standard Domain User with Descendant Computer Objects ("Reset password" permissions only) group member.

To allow this functionality, add the following permissions:

Reset Password
Validated write to DNS host name
Validated write to service principal
Read and write account restrictions
Read and write DNS host name attributes
Write servicePrincipalName

Other Upgrade Information

Immediately after you install version 25.08.11 on the ExtremeControlengine, the date and time does not properly synchronize and the following error message displays:

WARNING: Unable to synchronize to a NTP server. The time might not be correctly set on this device.

Ignore the error message and the date and time automatically synchronize after a short delay.

Additionally, the following message might display during the ExtremeControl upgrade to version 25.08.11:

No domain specified

To stop domain-specific winbindd process, run /etc/init.d/winbindd stop {example-domain.com}

Upgrading ExtremeControl Engine to Version 25.08.11

General Upgrade Information

The EAP-TLS Certificates with SHA1 are considered weak and are not accepted anymore. The radius server fails to start with the SHA1 certificate. You can use a more secure certificate, such as SHA256.

You are not required to upgrade your ExtremeControl engine version to 25.08.11 when upgrading to ExtremeCloud IQ Site Engine version 25.08.11. However, both ExtremeCloud IQ Site Engine and ExtremeControl engine must be at version 25.08.11 in order to take advantage of the new ExtremeControl version 25.08.11 features. ExtremeCloud IQ Site Engine version 25.08.11 supports managing ExtremeControl engine versions 23.x and up to 25.08.11.

In addition, if your ExtremeControl solution utilizes a Nessus assessment server, you should also upgrade your assessment agent adapter to version 25.08.11 if you upgrade to ExtremeControl version 25.08.11.

You can download the latest ExtremeControl engine version at the Extreme Portal.

LDAPS servers with FQDN

If the LDAPS server URL uses a Fully Qualified Domain Name (FQDN), then the LDAPS client of Access Control Engine presents the internal Communication Certificate to the LDAPS server. If the LDAPS server URL uses a FQDN then the LDAPS client of ExtremeCloud IQ Site Engine presents the Server Certificate (located in Administration > Certificates > Server Certificate Information) to the LDAPS server. If the LDAPS server presents a certificate that does not match the LDAPS URL, then the certificate is rejected with the error “Certificate Unknown”

The best practice is to use trusted certificates if the LDAPS URL is defined with FQDN, otherwise the LDAPS server might not accept the LDAPS connection. If the LDAPS server URL uses an IP address then the LDAPS client (of both Access Control Engine and ExtremeCloud IQ Site Engine) does not present the Certificate to the LDAPS server.

Upgrading to Policy Manager 25.08.11

Policy Manager 25.08.11 only supports ExtremeWireless Controller version 8.01.03 and higher. If you upgrade to ExtremeCloud IQ Site Engine 25.08.11 prior to upgrading your controllers, then Policy Manager does not allow you to open a domain where the controllers already exist or add them to a domain. A dialog is displayed indicating your controllers do not meet minimum version requirements and that they must be upgraded before they can be in a domain.
Following an upgrade to Wireless Controller version 8.31 and higher, a Policy Manager enforce fails if it includes changes to the default access control or any rules that are set to contain. To allow Policy Manager to modify the default access control or set rules to contain, you must disable the "Allow" action in policy rules contains to the VLAN assigned by the role checkbox accessed from the Wireless Controller's web interface on the Roles > Policy Rules tab. This will allow the enforce operation to succeed.

Fabric Configuration Information

Certificate

Fabric Manager might be unavailable via ExtremeCloud IQ Site Engine after upgrading if the certificate is missing in ExtremeCloud IQ Site Engine Trust store.

To ensure Fabric Manager is available, enter the Fabric Manager certificate in the ExtremeCloud IQ Site Engine Trust store using Generate Certificate option. See Add Fabric Manager Certificate for the certificate procedure.

Authentication Key

When you provision authentication keys for Fabric Attach, the key cannot be read back for security reasons. When the key is read from the device, it always shows "****". For this reason, it might seem that there is a configuration mismatch when one does not exist.

Service Configuration Change

If you change a configured service via the Configure Device window that references one of the following, and then enforce those changes to the device, the configuration on the device might change unexpectedly:

MLT
SMLT
Port-specific settings to a port belonging to an MLT or SMLT

To prevent this merge, change rows in the Enforce Preview window where MLT or SMLT are in use from Current to Desired.

To correct the issue after enforcement, modify the service on the device via the CLI.

CLIP Addresses

Using the CLIP Addresses table in the Configure Device window, you can enter addresses in both IPv4 and IPv6 formats. However, ExtremeCloud IQ Site Engine version 25.08.11 only supports applying a single address (either IPv4 or IPv6) to a Loopback Interface.

Upgrading VSP-8600

When upgrading from Extreme Management Center version 8.2 to version 8.3. manually reload previously discovered VSP-8600 devices to gain access to Fabric Connect features.

Removing Fabric Connect Configuration

Removing a device's Fabric Connect configuration by setting the Topology Definition to <None> may fail if the device has Logical Interfaces assigned to ISIS.

Password Configuration

Fabric Manager fails to onboard in ExtremeCloud IQ Site Engine if the root password includes an ampersand (&) character. Additionally, if the Administration > Inventory Manager > SCP tab contains a password that includes an ampersand (&) in ExtremeCloud IQ Site Engine, the Fabric Manager firmware does not download successfully.

Ensure you use a password without an ampersand (&) character.

VRF Configuration

Fabric Engine SNMP performance is adversely affected as the number of VRF configurations increases. This issue can be resolved by upgrading toFabric Engine release 8.1.1 or later or VSP-8600 series version 6.3.3 or later.

Device Configuration Information

VDX Device Configuration

To properly discover interfaces and links for VDX devices in ExtremeCloud IQ Site Engine, enable three-tuple-if on the device.

NOTE:

To enable three-tuple-if on the device in ExtremeCloud IQ Site Engine:

Access the Network > Devices tab.
Right-click on the device in the Devices table.
Select Tasks > Config > VDX Config Basic Support.

Additionally, for ExtremeCloud IQ Site Engine to display VCS fabric , the NOS version must be 7.2.0a or later.

Rediscover VDX devices after upgrading to ExtremeCloud IQ Site Engine.

Fabric Engine Device Configuration

Topology links from Fabric Engine devices to other Fabric Engine or ERS devices might not display in a topology map (or might display inconsistently). To ensure topology map links display correctly, verify that the Fabric Engine device is configured to publish its management IP address in the autotopology (SONMP) data.

Ensure that the output of show sys setting command shows:

autotopology : on ForceTopologyIpFlag : true clipId-topology-ip : 0

If the output values displayed are different, configure the Fabric Engine device to publish management IP address in SONMP data by executing the following CLI commands:

(config)# autotopology (config)# sys force-topology-ip-flag enable (config)# default sys clipId-topology-ip

The Status of LAG links in maps will start working after the next polling following an upgrade to ExtremeCloud IQ Site Engine. You can initiate the polling of a device by performing a refresh/rediscovery of the device.

ERS Device Configuration

ERS devices might automatically change VLAN configurations you define in ExtremeCloud IQ Site Engine. To disable this, change the vlan configcontrol setting for ERS devices you add to ExtremeCloud IQ Site Engine by entering the following in the device command line:

CLI commands enable config term vlan configcontrol flexible

Additionally, configure all VLANs on the port for an ERS device with the same tag status (tagged or untagged). If enforcing to an ERS device on which a port has at least one VLAN as tagged, ExtremeCloud IQ Site Engine adds all untagged VLANs to the tagged VLAN list and clears the untagged VLAN list.

Creating an archive for ERS devices using the Network > Archives tab does not complete successfully if Menu mode (cmd-interface menu) is used instead of CLI mode (cmd-interface cli). See How To Set Default Management Interface To Either Menu or CLI Mode (https://extremeportal.force.com/ExtrArticleDetail?an=000077274) to create the archive.

SLX Device Configuration

When creating a ZTP+ Configuration for an SLX 9240 on which firmware version 18s.01.01 or 18s.01.02 is installed, the ZTP+ process fails if the Administration Profile value uses SSH or Telnet CLI credentials. ExtremeCloud IQ Site Engine indicates that the SSH or CLI profile is not supported by the device.

To create a ZTP+ configuration for an SLX 9240:

Create a new Device Profile with the CLI Credential set to < No Access >.

NOTE:

The SLX ZTP+ Connector does NOT support configuring CLI credentials on the device.

Create the ZTP+ Configuration and select the new Device Profile you created in Step 1 as the Administration Profile.
After the ZTP+ process successfully completes and the device is added to ExtremeCloud IQ Site Engine, select a Device Profile that uses the correct CLI credentials for the SLX device in the Administration Profile.

ExtremeXOS Device Configuration

ExtremeXOS/Switch Engine devices on which firmware version 30.3.1.6 is installed do not download and install new firmware versions successfully via the ZTP+ process. To correct the issue, access the Network > Firmware tab in ExtremeCloud IQ Site Engine, select the ExtremeXOS device you are updating via ZTP+, and change the Version field in the Details right-panel from builds/xos_30.3/30.3.1.6 to 30.3.1.6.

Firmware Upgrade Configuration Information

ExtremeCloud IQ Site Engine supports firmware downloads and uploads to devices using TFTP, FTP, SCP, and SFTP. However, before firmware images can be downloaded or uploaded from the server, ExtremeCloud IQ Site Engine needs the root path or directory for each of the protocols. The following default root paths for each protocol are configurable from the Administration > Options > Inventory Manager tab:

Protocol Root Path:

TFTP: /tftpboot/firmware/images/
FTP: /tftpboot/firmware/images/
SCP: /root/firmware/images/
SFTP: /root/firmware/images/

To upload firmware images that are 2 GB or less to the server, use the ExtremeCloud IQ Site EngineNetwork > Firmware tab. For files larger than 2 GB, use a third-party client (such as SCP, WinSCP, or FTP).

For example, to use SCP to upload a firmware image to the SCP root path on the server, enter the following:

scp <LOCAL_FIRMWARE_PATH> root@<ExtremeCloud IQ Site Engine_SERVER_IP>:/root/firmware/images
Where:
- <ExtremeCloud IQ Site Engine_SERVER_IP>= IP Address to ExtremeCloud IQ Site Engine Server
- <LOCAL_FIRMWARE_PATH>= fully qualified path to a firmware image on the client machine

Wireless Manager Upgrade Information

A High Availability pair cannot be added as a flow source if the WLAN(s) selected are not in common with both wireless controllers.

Server and Client System Requirements

IMPORTANT:

Wireless event collection is disabled by default in version 25.08.11 due to the increase in disk space usage required. To enable event collection, select Enable Event CollectionEvent Analyze. Then select Administration > Options > Event Analyze.

Internet Explorer is not supported in ExtremeCloud IQ Site Engine version 25.08.11.
