When the switch shuts down, it sends an attachment notification with the state delete and the IP address
before closing the NMSP connection to the MSE. The MSE interprets this notification as disassociation
for all the wired clients associated with the switch.
If you change a location address on the switch, the switch sends an NMSP location notification message
that identifies the affected ports and the changed address information.
