UI Unification

Nozomi Networks is unifying the user experience across its products, including N2OS and Vantage. The goal is to make the interaction with our systems more consistent and to simplify the operations performed by the user.

N2OS 23.1.0 sets the new navigation bar by default. The new navigation bar was introduced in 23.0.0 and in Vantage at the same time. Its goal is to give a quicker access to the most used areas of the products. The old navigation bar can still be enabled through a toggle in the drop-down user menu. However, the old navigation bar will be removed in a future release.

The "Assets" page (previously "Asset view") has received graphical enhancements, as is the case also for the alert details dialog. The "Network view" and "Process view" pages have been renamed to "Network" and "Process" respectively. The favicon of the webinterface is now different for Guardian and CMC.

LACP and EtherChannel

Physical Guardian now supports Monitoring ports with Static EtherChannel, on an experimental basis, enabling link aggregation with "EtherChannel on mode" between N2OS and Cisco 9300 switches with firmware v17.6.3.

Physical Guardian and CMC sensors now support Management port with Link Aggregation Control Protocol LACP IEEE 802.3ad standard on an experimental basis, enabling Ethernet channels between N2OS and switches. Available for Cisco 9300 switches with firmware v17.6.3 and ARUBA 2530 switches with firmware vYA16.11.

Reliability Improvements

Versions 22.6.2 and 23.0.0 introduced important enhancements that improved dramatically the reliability and life span of our physical appliances, particularly Remote Collector. Version 23.1.0 continues this trend by implementing important updates to the range of supported hardware.

The memory management for the n2os_rc process has been improved, solving a few cases of crashes due to out-of-memory situations.

The version upgrade process has received stability improvements, solving a case in which multiple reboots were necessary to complete the update.

The data reset operation is now quicker and more reliable, including the feature that allows to play a trace with the "delete all data" toggle enabled, solving a case where this operation could timeout on machines with low resources.

Some filesystem directories have received performance and consistency improvements. Quarantined files are now kept in a RAM drive when the system host has sufficient memory. The traces are now kept in the /var/traces directory.

Support for RUGGEDOM sensors is reintroduced via the release N2OS 23.1.0. Full compatibility with the APE1808 platform has been restored. The recommended upgrade path is to upgrade to N2OS 22.6.2 and then immediately upgrade to N2OS 23.1.0, skipping N2OS 23.0.0, which does not support RUGGEDCOM and cannot be installed on these sensors.
