Enable LEDBAT For SCCM SUP and DP

In this article, you’ll learn how to enable LEDBAT for SCCM software update points (SUP) and distribution points (DP).

You can enable Windows Low Extra Delay Background Transport (LEDBAT) for your software update points. This is a new feature introduced in SCCM 2203 release.

LEDBAT adjusts download speeds during client scans against WSUS to help control network congestion. It is a very useful feature in Configuration Manager.

To enable LEDBAT for SCCM software update points, you must first upgrade to SCCM 2203. The LEDBAT feature for SUP is available only with Configuration Manager version 2203.

You can enable Windows Low Extra Delay Background Transport (LEDBAT) for your software update points and distribution points that run Windows Server 2016 or later.

If you have a site system that has both the distribution point and software update point roles, you must configure LEDBAT independently on the roles.

For example, if you only enable LEDBAT on the distribution point role, the software update point role doesn’t inherit the same configuration. You’ll have to enable LEDBAT on SUP separately.

In this guide, I will show you how to enable LEDBAT on SCCM DP and SCCM SUP separately.
