Confidential data in support archives is now always encrypted.
Starting with this version, Nozomi Networks sensors will refuse a manual installation of a new version if the upgrade path presented in the release notes is not followed. Additionally, if this is the case, the sensor will not install subsequent versions. In such a situation, connect to the sensor via secure shell (SSH) and verify that the /data/upgrade-failed file indicates only an installation path violation. If that is the case, remove the file and proceed with the version upgrade. Follow the mandatory installation path.
The SFP ports of the NS1R physical sensor now support traffic monitoring at 100 Mbps using HWA-TRS-T-P 100/1000 BaseT transceivers.
