Network port flapping detection and notification

Port flapping is a condition where network ports have gone down and come up in quick succession. Stacking ports and Link Aggregation Group (LAG) ports both have flap detection and notification. These features are available on the HPE Virtual Connect SE 40Gb F8 Module for HPE Synergy and HPE Virtual Connect SE 100Gb F32 Module for HPE Synergy interconnects.

When LAG flapping is detected on uplink or downlink ports, or port flapping on stacking ports, alerts are displayed on the Interconnects screen. The alert lists the ports that triggered the port flapping. These alerts are cleared automatically if the flapping is not detected for a predefined amount of time.

NOTE:

Downlink ports must be associated with a Virtual Port Link Aggregation Group (VPLAG) ID to detect if the LAG is flapping.
