instrumentation monitor pkts-to-closed-ports

[APBOB]

Hello,

Where I can find detailed information on how works detection, where switch detects (on which Ethernet port, or detection is on MNG CPU port, or on which VLAN etc) how to troubleshoot "instrumentation monitor pkts-to-closed-ports". I have a lot of records related to "00830 inst-mon: ST1-CMDR: Limit for Pkts to closed ports (XXX) is exceeded (XXX)" and can't find any normal troubleshooting information on this in documentation, expect "Number of packets sent to closed switch TCP/UDP ports which could be related to ports scan". Capturing the data on each VLAN (I have 49) and check which device could generate such traffic isn't not an option...

Thanks in advice!
