Nearest Switch Test
An integral part of discovery is locating the switches on
the network. The Nearest Switch test uses SNMP to

that the instrument is connected to. After the nearest
switch is discovered, its active ports are monitored for
utilization and errors.
1. To check the status of the nearest switch, tap
