This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
Switch Miner (Cisco switch port mapper)
Switch Miner is a free lightweight open source command line utility for
Windows that acts as a switch port mapper/switch port discovery tool.
It helps network engineers discover the devices that are connected to
the all the ports of a switch. It will even discover neighboring
CDP and scan them also. Using SNMP it scans switches and creates excel
.xlsx or .csv files.
