Loop detected but feature not enabled
I'm getting this error on two our netgear switches. So on this switch it is showing the error you see below. I'm not sure what feature its referring to. I enabled layer 2 loop guard (from my understa...
Neither an error nor a supposed loop.
Message more or less clearly says some STP BPDU is ignored. This does indicate some STP activity, not the active loop guard sending out specifcly crafted frames whih are used to monitor the other ports ... this is what would report a real loop then.
schumaku Thank you for the reply. Forgive me as its my first time working with Netgear products. So correct me anywhere I'm wrong but If I'm to understand what you're saying, its that this is simply a message that is indicating that STP is doing its thing, ignoring PDUs that could cause a loop but its ignoring the PDU so it doesn't. I mean, out side of these log messages, I haven't noticed any issues with our network in terms of it being slow or coming to a halt.
If I'm correct in that assumption, my next question would be is how to get it to stop spamming it multiple times a second? I suppose I could disable spanning-tree notifications and enable it when I suspect an issue with it but I'd rather not do that but at the same time, it makes troubleshooting other issues via log messages a bit difficult as only so many log messages can be on that page so unless I catch the problem at the exact point in time, as soon as I refresh, all I see is the notification about ignored PDU
