Heavy Networking 690: LACP Is Not Link Aggregation – With Tony Bourke
On today’s Heavy Networking we talk LACP and link aggregation. While bonding two or more links together to act as a single virtual link has been done for decades, LACP and link aggregation aren't the same thing, and the distinction matters. Our guest to get into the differences is network instructor Tony Bourke.

Quickly see differences between Zone Versions with Version Comparisons
On the week of July 10, 2023, we launched a new capability for Zone Versioning - Version Comparisons. With Version Comparisons, you can quickly get a side by side glance of what changes were made between two versions. This makes it easier to evaluate that a new version of your zone’s configuration is correct before deploying to production.
A quick recap about Zone Versioning
Zone Versioning was launched at the start of 2023 to all Cloudflare Enterprise customers and allows you to create and manage independent versions of your zone configuration. This enables you to safely configure a set of configuration changes and progressively roll out those changes together to predefined environments of traffic. Having the ability to carefully test changes in a test or staging environment before deploying them to production, can help catch configuration issues before they can have a large impact on your zone’s traffic. See the general availability announcement blog for a deeper dive on the overall capability.
Why we built Version Comparisons
Diff is a well known and often used tool by many software developers to quickly understand the difference between two files. While originally just a command line utility it is now ubiquitous across Continue reading
Subscription and Host Metric Changes in Ansible Automation Platform 2.4
What and Why?
Our customers use Ansible Automation Platform across a multitude of platforms, in a plethora of ways. Providing an accurate accounting and reporting capability is sometimes difficult across the various types of use cases we encounter.
If you have traditionally used the platform with infrequently changing or more static types of managed hosts, you’re probably pretty much covered. If however, you administer a more diverse and dynamic set of hosts, there may be occasions where you require more flexibility, when accounting for managed hosts against your purchased subscription.
That’s why in Ansible Automation Platform 2.4, we’ve introduced a new Host Metrics dashboard tab with the ability to:
- View high level automation run details per managed host
- The first and last time automated (this metric already existed)
- The number of times automation has been run or attempted to be run against a host (new in 2.4)
- The number of times a managed host has been deleted (new in 2.4)
The ability to view the number of times automation has been run on hosts is a simple but really useful metric:
- Instantly see your most commonly automated hosts
- See which hosts exist in Continue reading
Linux Is The Next Platform, But Who Pays To Maintain It?
Red Hat has once again dropped another huge boulder into the normally serene – or at least relatively calm – open source waters. …

Hedge 186: Hardware Root of Trust
The idea of a root of trust is somewhat foreign to network engineers—what is it, and why would it be important? Michael and Marcus from Hedgehog join Tom Ammon and Russ White to discuss how hardware roots of trust work, what problems they are designed to solve for network hardware, and the current state of this technology.

Deploy real-time network dashboards using Docker compose
This article demonstrates how to use docker compose to quickly deploy a real-time network analytics stack that includes the sFlow-RT analytics engine, Prometheus time series database, and Grafana to create dashboards.
git clone https://github.com/sflow-rt/prometheus-grafana.git cd prometheus-grafana ./start.shDownload the sflow-rt/prometheus-grafana project from GitHub on a system with Docker installed and start the containers. The start.sh script runs docker compose to bring up the containers specified in the compose.yml file, passing in user information so that the containers have correct permission to write data files in the prometheus and grafana directories.
All the Docker images in this example are available for both x86 and ARM processors, so this stack can be deployed on Intel/AMD platforms as well as Apple M1/M2 or Raspberry Pi. Raspberry Pi 4 real-time network analytics describes how to configure a Raspberry Pi 4 to run Docker and perform real-time network analytics and is a simple way to run this stack for smaller networks.
Configure sFlow Agents in network devices to stream sFlow telemetry to the host running the analytics stack. See Getting Started for information on how to verify that sFlow telemetry is being received.
Out-of-band Management – Useful Beyond Catastrophe
I was lucky enough to participate in Tech Field Day Extra at Cisco Live a couple weeks months ago. This event brings independent thought leaders together with a number of IT product vendors that were at Cisco Live to share information and opinions. I was not paid to attend, but the organizers did provide some meals while I was there. There is no expectation of providing any content, so the fact that I’m mentioning it says something. It was a great event and worth a few hours to check out the videos. Thanks to Gestalt IT for getting me involved. OpenGear was there, and it was good to see some new faces and hear some new ideas.
For those that live under a rock don’t know, OpenGear traditionally provides out-of-band (OOB) management solutions via hardware appliances that run independently of your network. They, like other vendors in that space, can connect to the cellular data network of choice and provide access to your gear when something fails (what OpenGear calls “worst day”). Over 99.9% of the time, though, you would never use your OOB devices. They’re just going to sit there doing nothing until that day that something fails Continue reading
