As data center networks become increasingly complex and virtualized, the need for a unified, automated policy-based approach to managing them grows. Cisco Application Centric Infrastructure (ACI) is designed to meet this challenge by providing a single point of policy definition and enforcement for the entire network.
In this article, we will take a look at how ACI LAG Suspend Individual works, and how it can be used to improve the availability of your data center network.
When a link in a LAG is not functioning properly, it can be suspended by ACI so that traffic is no longer sent over that link. This ensures that only healthy links are used, and that traffic is not interrupted or lost.
ACI LAG Suspend Individual is a feature that is particularly useful in high-availability environments, where it is important to minimize the risk of data loss. By automatically suspending links that are not functioning properly, ACI can help to ensure that traffic is always sent over the best possible path.
In order to use ACI LAG Suspend Individual, you must first configure a LAG. This can be done using the ACI GUI or CLI. Once a LAG has been created, you can then add links to it.
Once you have added links to a LAG, you can configure ACI LAG Suspend Individual by going to the Link Aggregation Groups page in the ACI GUI. From here, you can select the LAG that you want to configure, and then click the “Edit” button.
In the Link Aggregation Group Configuration window, you will see a section called “Link Suspension”. Here, you can select the “Enable Link Suspension” checkbox to enable the feature.
Once you have enabled Link Suspension, you can then configure how many links must be down before traffic is no longer sent over the LAG. This is done by setting the “Minimum Active Links” option.
For example, if you set the “Minimum Active Links” option to 2, then traffic will only be sent over the LAG if at least 2 links are up. If one or more links are down, traffic will be rerouted so that it is not sent over the LAG.
Once you have configured ACI LAG Suspend Individual, it will automatically suspend links that are not functioning properly. This will help to ensure that traffic is always sent over the best possible path, and that data is not lost.
