Link Down Error

Hello,

Bit of an Extreme novice but I have installed ridgeline to monitor our 50+ extreme XOS switches and im seeing a lot of alarms for "Link Down", there coming in very regularly and looking closer at the switches logs it seems be numerous ports and there running at odd speeds.

Is this just devices being turned on / off, if it is it seems to happening a bit too often or could there be an issue that's making a lot of the ports across my network go up and down and if so any pointers on how to fault find?

Thanks, Andrew

Hey aengland

Most of the time these are user ports. One thing to check is to do a show port info detail on your uplink or critical ports and see if the link up/down counters are incrementing.

In ridgeline it is useful to create port groups for you uplink ports or critical devices ports and only configure link down alarms for those port groups not all ports.

Let me know if his helps
