Netris 4.16.0 Release Notes (Sep/02/2026)

What’s new in Netris 4.16.0?

This release brings centralized log forwarding to the switch fabric: syslog destinations are now configured once in an Inventory Profile and applied across every Netris-managed switch platform. It also adds support for Cumulus Linux 5.18.0, validation that rejects unworkable IPv6 Router Advertisement and route-map settings before they reach the fabric, along with fixes across VPC peering, V-Net configuration, ACL enforcement, and BGP session and port health reporting.

Features

  • Syslog Destination Configuration in Inventory Profiles. Inventory Profiles now support syslog destination configuration, enabling switches to forward system logs to central logging infrastructure with no per-switch manual setup. Multiple destinations can be configured per profile, each specified as an IPv4 address or a fully qualified domain name, with port — and each with its own transport protocol and minimum severity level. Supported across all Netris-managed switch platforms and configurable through both UI and API.

Enhancements

  • Per-field hardware object updates. Hardware objects can now be updated field by field through the Controller API, leaving attributes that are not included in the request untouched. Existing full-replacement updates continue to behave as before, so current automation is unaffected.

  • Cumulus Linux 5.18.0 support. Netris is now validated on Cumulus Linux 5.18.0.

Bug fixes

  • Fixed SoftGate installation hanging during the migration from Netplan to ifupdown on systems that do not ship a DHCP client package, such as Ubuntu 24.04.

  • Fixed a VLAN ID collision during switch port translation that could leave the agent retrying configuration indefinitely. Affected platforms: Arista.

  • Fixed a Site Default ACL Policy of Deny not being enforced for DNAT and IPv6 traffic. Affected platforms: SoftGate. Found in Netris 4.14 and later.

  • Fixed Netris DHCP traffic being dropped when a Site’s Default ACL Policy is set to Deny. Found in Netris 4.8 and later.

  • Fixed missing notifications when an External BGP session on a SoftGate goes down. Found in Netris 4.14 and later.

  • Fixed healthy switch ports being displayed in an unknown state. Affected platforms: all. Found in Netris 4.14 and later.

  • Prefix lists can no longer be deleted while still referenced by a route-map. Affected platforms: all. Found in Netris 4.14 and later.

  • IPv6 Router Advertisement settings are now validated so that the advertisement interval cannot exceed the router lifetime, and both values are checked against their supported ranges. Affected platforms: all. Found in Netris 4.15 and later.

  • Fixed the switch agent attempting to configure interfaces that the Netris Controller has not yet discovered or inventoried, resulting in an invalid configuration. Affected platforms: Arista. Found in Netris 4.14 and later.

  • Fixed VPC peering routes not being learned on switches that host only one of the two peered VPCs. Affected platforms: Cumulus. Found in Netris 4.15 and later.

  • V-Net configuration is now fully withdrawn from the switch when the corresponding object is removed or disabled, including:

    • anycast MAC address configuration when a gateway is removed from a V-Net

    • bridge member configuration on member ports when a V-Net is disabled

    Affected platforms: Cumulus. Found in Netris 4.15 and later.

Security fixes

No security fixes in this release.

Deprecation Notices

  • Switch fabric selection removed. Every site is now managed as a Netris-native fabric, and the fabric selector has been removed from Site configuration in the UI. The switchFabricProviders attribute has been removed from the Sites API. switchFabric is still returned on read, always as netris, and is ignored if supplied on create or update; it will be removed in a future release.
