Hello,
I'm new to the forum and would like to ask a question regarding STP topology, hoping that someone could have an idea of what may be going on with our network.
We currently have 100+ HP 1910s and 1920s switches and most of them are showing lots of messages saying "Instance 0's port [Uplink port] was notified of a topology change." I have done research already without anything conclusive. It seems that there is a lot of traffic on the network, maybe some ARP scans, etc.
Any clues?
Thanks.
