if I try to connect a new access switch (Summit X440-48) to the core switch (BD8006) I read after some minutes the following entry in the log file:
MSM-A: Notify-threshold for L3 Protect packet count of 3500 reached
MSM-A: Added an ACL to port 4:1, srcIP 0.0.0.0 to destIP 10.72.50.100, protocol udp
After that several servers are not reachable (but the new access switch is reachable via ping). If I disconnect the new switch everything is fine.
So what is wrong?
