Cumulus Linux 3.1 is released!


Userlevel 5
We are excited to announce the release of Cumulus Linux 3.1, which accelerates the architectural transition to 25/100G leaf-spine topologies from 10/40G for public and private cloud customers.

Architecting a network with 25/100G switches offers higher capacity and 2.5 times more bandwidth for almost the same cost as 10/40G while future proofing your investments. This release broadens our portfolio of 25/100G platforms across multiple ASICs to include new platforms from Mellanox, Edge-Core, and HPE.

To expedite the adoption of 25/100G leaf-spine topology, we are expanding our HCL to support the industry’s first dedicated 25G switch from Mellanox. Additional new platforms supported by this release include half-width 100G and 40G open Ethernet switches from Mellanox for hyper-converged and other lower density environments.

Cumulus Linux 3.1 includes wide range of new and enhanced software features, including VXLAN with VLAN-aware bridges and tunable forwarding table profiles.

Please refer to the release notes to get the details for all the new features.

very nice, quick question,
forwarding_table.profile, default vs v4-lpm-heavy, v6-lpm-heavy
doc isn't very clear about the difference, scale number looks same to me.
I am hoping to be able to support QinQ tunneling on a Cumulus box soon. I had heard that this was on the roadmap and may be available in 3.1 or 3.2. I checked the release notes for 3.1 and did not see any mention of QinQ. Is there any update on when or what version this may be supported?

Thanks!
+1 for qinq
