cnMatrix 6.2.1-r3 is Here – More Resilient, More Capable, Better Managed
We’re excited to announce the availability of Cambium Networks Enterprise cnMatrix Release 6.2.1-r3, delivering enhanced resiliency, broader Layer 3 capabilities, improved interoperability, and important stability fixes across the cnMatrix portfolio.
What’s New
VRRPv2 Support Across All Switch Models
High availability just got better. VRRPv2 is now supported on all cnMatrix switch models, enabling seamless gateway redundancy and improved network uptime across deployments.
Improved Transceiver Compatibility
To improve interoperability with third-party optics, EX3030RM-P and EX3052RM-P now automatically default to 10G operation when an SFP28 transceiver cannot be positively identified. This change provides more reliable connectivity while maintaining compatibility with a broader range of optics.
Auto-VLAN Support for Port Channels
Auto-VLAN functionality has been extended to port channels, simplifying deployments where aggregated links are used and reducing manual configuration effort.
Key Bug Fixes
This release resolves several important issues affecting performance, routing, cloud management, and network stability, including:
- Fixed incorrect link status indication on EX30xxRM-P fiber ports.
- Improved DNS resiliency by utilizing the secondary DNS server when the primary becomes unavailable.
- Addressed ARP resolution issues in large-scale deployments.
- Resolved cnMaestro configuration synchronization problems involving PIM and static routes.
- Fixed random default route loss on EX3024F operating as a Layer 3 core switch.
- Corrected segmentation faults related to PBA MAC-based policy processing.
- Fixed static route handling when DHCP-learned and manually configured routes share the same next hop.
Deployment Notes
Before upgrading, please keep these recommendations in mind:
- Starting with software version 6.1, cnMatrix uses two separate software images based on hardware platforms. Ensure the correct image is selected for your switch model.
- Upgrading to 6.2.1 or later requires cnMaestro version 5.2.0-r10 or newer.
- For USB upgrades from releases earlier than 6.0, Cambium recommends shortening the firmware filename before copying it to the USB drive.
Known Issues
Release 6.2.1-r3 includes a few known limitations:
- EX3024F: Flow control is currently not functional.
- EX3024F: 2.5 Gbps port speed is not supported. Use 1 Gbps or 10 Gbps SFP/SFP+ transceivers instead.
Why Upgrade?
With expanded high availability, improved optics interoperability, enhanced automation, and multiple critical stability fixes, cnMatrix 6.2.1-r3 provides a more reliable and scalable foundation for enterprise and service provider networks.
We encourage all customers using supported platforms to evaluate this release and plan their upgrades accordingly.
