Netris 4.10.0 Release Notes (May/19/2026)

What’s new in Netris 4.10.0?

Warning

Monitoring data loss will occur when upgrading to Netris 4.10.0. Time-series data store changes from Graphite to VictoriaMetrics. The database is reinitialized during the upgrade, resulting in the loss of historical monitoring data. Future Netris releases will include a migration tool to preserve monitoring data during upgrades.

Features

  • Inventory Switch Role. Operators can now explicitly define each switch’s role (generic, leaf, spine, super-spine), which influences how the BGP underlay and EVPN address family are configured in the fabric. Existing switches are automatically assigned a role based on their location naming convention during the upgrade process. Inferring the switch role from the switch name is deprecated starting with Netris 4.10.0. See Adding Switches for more details.

  • Inventory Profile: Fabric Type. Adds a new Fabric Type (east-west, north-south, out-of-band, and general-purpose) property to Inventory Profiles, allowing administrators to define the fabric tier and traffic directionality for each profile. See Fabric Settings for more details.

  • Inventory Profile: Reference Architecture. Adds a new Reference Architecture selector to Inventory Profiles, allowing administrators to associate a profile with a recommended deployment pattern. See GPU Cluster Specific Settings for more details.

  • Hardware Multi-Plane Support. Adds support for multi-plane hardware configurations. See GPU Cluster Specific Settings for more details.

  • IP Address Family can be selected at Vnet level. Allows administrators to specify the IP address family (IPv4, IPv6, or dual-stack) at the Vnet level.

Enhancements

  • Graphite to VictoriaMetrics Migration. Replaces Graphite with VictoriaMetrics as the time-series database for monitoring data, improving performance and scalability.

  • Server Cluster Scalability. Improved the server cluster add/edit API to support creating clusters with a large number of servers (2000+) in a single operation.

  • Swagger API Documentation. Updated the Swagger API definitions with all missing API endpoints.

  • UFM Integration Enhancements. Added support for UFM synchronization debugging, dry-run mode, and change of reconciliation interval.

Bug fixes

  • Fixed L4LB not working when 1:1 DNAT rules are configured for the same backend IPs.

  • Fixed switch model not displaying correctly in the controller inventory for Cumulus Linux switches.

  • Fixed IPv4 and IPv6 addresses displaying concatenated without proper separation in the UI Network Links view.

  • Fixed IPv6 VPC peering not working as expected in multi-cluster topologies, a regression introduced in 4.9.0.

  • Fixed CloudStack agent not cleaning up VRF interfaces after the last VM in a VRF VNet is migrated or deleted.

  • Fixed suboptimal routing with VPC peering and EVPN Multihoming on Cumulus by implementing proper local leaking logic.

  • Fixed agent applying incomplete configurations for adaptive routing, a regression introduced in 4.8.0.

Security fixes

No security fixes in this release.
