Learn about the Lumen policy on border gateway protocol (BGP) prefix announcements for network services.
Traceroute is used by networking professionals to discover the path network traffic takes. Learn more about traceroute and how it can help you troubleshoot issues with your service.
Lumen uses industry-standard testing to help ensure that your ethernet-enabled services perform correctly at turn-up and continue to meet your business needs. This article covers those testing methodologies.
Learn more about traceroutes and how it handles timeouts and unreachables in analyzing your network traffic.
Learn about TCP windowing and how it relates to TCP performance over WAN connections.
As a foundation to using traceroute to diagnose issues with your network traffic flow, learn more about how traceroute works.
Learn more about traceroute and how to read the output to help you analyze network traffic flow.
Learn how traceroute can be helpful in diagnosing issues with your network traffic.
Learn more about traceroute and important function of IP routing; routing isn’t always symmetrical and, in the case of the Internet, it’s often asymmetrical.
Learn more about traffic shaping, when to use it, and where to apply it to analyzing your network traffic.
If you have two, or more, redundant Lumen MPLS circuits, you can configure your router for failover. Doing this requires a one-time, configuration change, which you can do yourself.
Traffic shaping is configurable on many vendors and platforms. In this article we cover some of the more common vendors/platforms and how to configure traffic shaping on these network devices.
Learn when traceroute can mislead you in diagnosing network traffic issues.
Learn how to resolve throughput issues related to your MAC address. If your MAC address begins with a 4 or a 6, this could contribute to packet reordering over your Lumen service—which may cause slow speeds.
You can run two types of circuit tests for your Lumen services in Control Center: a non-intrusive, performance metric test and an intrusive test.
You can view a list of the circuit tests you've run as well as their status in Control Center. Circuit testing history is updated hourly. If a non-intrusive performance metrics test returns an error, you'll be prompted to create a repair ticket and schedule an intrusive test.
In Control Center, you can run a non-intrusive performance metrics test if you're having trouble with a circuit to diagnose the problem. Depending on the results of the test, you can request an intrusive test to further diagnose the problem or open a repair ticket to request that Lumen resolve the issue. You must run this non-intrusive test on a circuit first and then you can request an intrusive test.
Use this guide to help you through your activation and to ensure you can begin using your new Lumen services as quickly as possible.
