Procurve error log stp

Hello,
I have many logs entry on my switch that indicate port 15 is blocked by stp, then is now on-line.
It does that on some ports of my switchs, but not always the same.
There are some entries, then it goes to other port.
What do you think that mean ?
Tanks

It's normal. When a port comes up, spanning tree blocks it before putting it in a forwarding state.

On some hosts, the port will bounce while the host is booting up which causes the blocked, on-line, off-line, blocked, on-line sequence.

Don JohnstonInstructorCommented:
Whatever host is connected to port 23 is generating frames with an illegal source MAC address. Could be the NIC, NIC driver or even an app running on the host.
