+# Configure PML recovery
+
+Starting in the Slingshot Host Software (SHS) 11.1.0 release, PML recovery is supported for edge links. Edge links of earlier SHS versions will flap instead of recovering.
+
+PML recovery is disabled by default and must be enabled on the fabric before configuring it on the host. See the [PML recovery on the fabric](#./pml-recovery-on-the-fabric) section.
+
+PML recovery enables links to recover from transient faults that would otherwise cause the link to flap, without packet loss and only a brief delay in transmission. This can stabilize the fabric by reducing occasional random disruptions.
+
+Links that frequently PML recover require hardware action like repeat flappers. Monitor `HsnPmlRecoveryDetected` and `HsnLinkFlapDetected` Redfish events to identify maintenance candidates. See the "PML recovery summary events" section of the _HPE Slingshot Administration Guide_ for more information.
+
+Recovery must be enabled on both ends of a link. Use `ethtool` to enable it on the host as follows.
+
+```screen
+ethtool --set-priv-flags disable-pml-recovery off
+```
+
+## PML recovery on the fabric
+
+PML recovery is available for the HPE Slingshot fabric.
+See the "Configure PML recovery" section in the _HPE Slingshot Installation Guide_ for the environment you are installing.
