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.

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.

You gave a grade of "B".  

From the grading guidelines:

B is the grade given for acceptable solutions, or a link to an acceptable solution. A B grade means the solution given lacked some information or required you to do a good amount of extra work to resolve the problem. When closing the question, the asker should explain why a B grade was awarded.
