Switch's port Gi1/0/2 was blocked. This happens every few minutes. Why?
There is no loop in the network. Spanning tree is active.
How do I find out which device is causing this block to happen?
Hi @ChrisDV
Thanks for posting in our business forum.
This log means a loop has been detected. STP intervenes and stops the loop. That's why.
If you believe there is no loop, I am out of options.
You remove this device/cable from the port 1/0/2 and it'll stop. That's the fix.
@Clive_A Definitely no loop. And the problem moves around each switch. If I disable one, the blocking action moves to another AP and another switch.
