Description

This string tells us the source of the last topology change. This may be a MAC Address, if the bridge has received a TC BPDU, from another STP bridge, if it detected the change itself, then this will be a reason string indicating the cause of the TC. If no such TC has occurred then the string will have the value 'NONE…
