Netris 4.17.0 Release Notes (Sep/15/2026)

What’s new in Netris 4.17.0?

Netris 4.17.0 extends BGP Session and Peer-Port Decoupling to Dell SONiC, turns on FRR logging on SoftGates and adds the FRR logs to the Netris tech-support bundle, and improves the NVIDIA UFM integration’s deployment and PKey membership handling. It also adds support for Cumulus Linux 5.18.1, validation that rejects DHCP Relay together with L3VPN mode on V-Nets, along with fixes across VPC peering, DHCPv6 Relay on Arista, BGP session placement on Cumulus, Maintenance Mode on Arista, Controller Health, SoftGate health monitoring, the NAT API, and the Dashboard and Inventory Profile pages.

Features

No new features were added in this release.

Enhancements

  • BGP Session and Peer-Port Decoupling (Dell SONiC). On Dell SONiC, configure a BGP session on one switch while the port facing the BGP peer resides on another switch, giving you full flexibility in how BGP sessions are distributed across the fabric — independent of where peer connectivity physically lands. Works with any peer type (firewall, router, or server), and existing same-switch BGP configurations continue to work unchanged.

  • FRR logging on SoftGate. SoftGate now enables FRR logging by default, including BGP neighbor state changes, and the Netris tech-support bundle collects the FRR logs together with the rest of the SoftGate diagnostics.

  • NVIDIA UFM integration. Improvements to the Netris-UFM plugin, including:

    • The plugin integration credentials are now preserved when upgrading the UFM plugin.

    • You can now deploy additional UFM plugin instances by copying the ufm deployment folder and editing the deploy.yaml manifest.

    • The Netris UFM plugin now keeps all of a host’s InfiniBand HCAs in their assigned PKey. Previously, one or more adapters could disappear from the PKey after a host reboot, when UFM assigned duplicate module index values to adapters on the same host during rediscovery.

  • Cumulus Linux 5.18.1 support. Netris is now validated on Cumulus Linux 5.18.1.

Bug fixes

  • Fixed V-Net settings incorrectly accepting DHCP Relay or DHCPv6 Relay when L3VPN mode is enabled, a combination that is not supported.

  • Fixed the check_ratio monitor on SoftGates constantly reporting a high value.

  • Fixed VPC peering being configured on switches in a fabric where only one of the peered VPCs is present when a VPC spans multiple fabrics. Affected platforms: all.

  • Fixed DHCPv6 Relay not delivering addresses to servers in a V-Net. Affected platforms: Arista.

  • Fixed mismatched bridge and VNI configuration between switches when a BGP session is placed on one switch and its peer port on another. Affected platforms: Cumulus. Found in Netris 4.14 and later.

  • Fixed Controller Health not reporting when no license is applied or the license has expired.

  • Fixed the syslog server field in Inventory Profiles showing an IPv6 example address although IPv6 syslog destinations are not supported.

  • Fixed Maintenance Mode having no effect on switches. Affected platforms: Arista. Found in Netris 4.6 and later.

  • Fixed the Dashboard showing conflicting agent status between the summary widgets and the alarm list. Found in Netris 4.16 and later.

  • Fixed the SNMP and NetQ sections being expanded by default when editing an Inventory Profile. Found in Netris 4.15 and later.

  • Fixed the NAT API rejecting the protocol values shown in its own validation error message and Swagger example.

  • Fixed the validation error for the DHCPv4 Relay server field not being displayed when editing a V-Net. Found in Netris 4.16 and later.

Security fixes

No security fixes in this release.
