Comment:        Due to a spanning tree reconfiguration, the following switches have lost connectivity:

aco-sw-ml-204a-a
		aco-sw-ml-204a-b		
		aco-sw-ml-120b-b 
		aco-sw-ml-303c-a
			aco-sw-ml-303c-b
		aco-sw-ml-120b-a
		aco-sw-ml-110-a
			aco-sw-ml-110-b
		aco-sw-ml-204a-c


Currently investigating issue.

Update: Due to 2 switches 'aco-sw-ml-204a-b' and 'aco-sw-ml-110-b' needing a reload to change from RSTP to MSTP protocol, MSTP - Instance-1 was missing from the configuration. This caused the switches to loose network connectivity. Once Instance 1 was configured on location, network connectivity was restored. All ML building Switches were offline due to switch 'aco-sw-ml-204a-a' improperly rebooting and not loading its primary image. A hard reset fixed this issue.
