Upgrade Considerations


Before upgrading please review the Upgrade Considerations and the Rolling Back Software pages. Several modifications have been made to the process for verifying configurations, which will impact existing configurations.

  • I95-43243/IN-460 Upgrade and Rollback: Upgrading or rolling back a system (conductor peer or router) with the interactive installer install128t, that is managed by a conductor may result in the system becoming unresponsive. It is highly recommended that upgrades be performed through the conductor UI. Manual upgrades and rollbacks may not be resilient to failures. See Rolling Back Software for more information on these operations.

  • I95-42452 Conductor Upgrade Time: Upgrades to version 5.4 and above can take up to 40 minutes due to the number of rpms being upgraded. Please plan accordingly.

  • I95-42624 Upgrade Installer: Before upgrading to, or installing version 5.4 and above, update the Installer to at least version 3.1.0. Failing to upgrade the installer may result in a rollback failure, should a rollback be necessary at any time. The Installer typically prompts you update when a new version is available. Select Update when prompted.

  • Plugin Upgrades: If you are running with plugins, updates are required for some plugins before upgrading the conductor to SSR version 5.4.0 or higher. Please review the Plugin Configuration Generation Changes for additional information.

Release 6.0.0-56

Release Date: July 18, 2022

New Features

  • I95-35794 IP TTL Handling: The SSR's handling of SVR traffic can be configured to adjust the TTL value on hops between SSR routers. This adjustment can prevent situations where the TTL expires on packets flowing through multiple hops and then out to the Internet to their final destination. For more information, see TTL Handling.

  • I95-40373 Appliance Image-based Installation: An image-based ISO installation process has been implemented for users who manage their network using the Mist Cloud. For a full description of this feature, see Image-Based Installation.

  • I95-44267 NIST FIPS Validated Cryptography: FIPS Enforcement Mode has been added to both the new image-based and existing package-based installation processes. See Image-Based Installation for FIPS activation steps as part of the image-based installation. Refer to FIPS Enforcement Mode for details using the legacy package-based installation.

  • I95-46411 PPPoE over VLAN interface status missing in show commands: Added atttribute to show the missing information.

  • I95-46822 Revertible failover traffic not restored when reverse traffic is present: For a "revertible-failover" service policy, when the preferred path is restored and a session no longer traverses an internode dogleg path, it was taking several seconds for traffic to be restored when forward traffic is present; in situations where only reverse traffic is present, traffic may not be restored. This issue has been resolved.

  • I95-46826 Carrier detection logic not recognizing disaster recovery modem: Updated the carrier detection logic to properly recognize the carrier when a modem is attached to a disaster recovery cell tower.

  • WAN-1191 - Incorrect interface Port Mapping for Silicom Madrid supported platforms: This update corrects the port mappings. It is recommended that the latest image be used for all image-based installs. For information about Image-based installs and where to download the latest ISO, please refer to Image-Based Installation.


  • I95-46684 Image-based Installer / Interactive Installer: When using the image-based 6.0 installation, be aware that if Interactive Install is selected, intialize128t does not launch automatically on first boot. This must be run manually; log in to the console as root using the default credentials, and type initialize128t to perform interactive initialization. This will be resolved in a future release.

  • I95-47095/MIST-66000 LAN Redundancy breaks WAN Redundancy (Mist-managed): If you need to convert a LAN or WAN interface from non-redundant to redundant or from redundant to non-redundant, the affected nodes must be restarted.

  • MIST-65629 Traffic Shaping (SSR Only) option not available (Mist-managed): Traffic engineering may not be properly enabled in a high availability configuration for Mist-managed SSR's. This issue is under investigation.
