Does Placing an Upstream Device into Maintenance Mode Suppress Alarms for Downstream Devices?
Release : 20.2.x
Component : SPCAEM - Events and Alarms
It does not and this is functioning as designed. Placing an upstream device into Maintenance mode will have no effect on the fault isolation to the down-stream devices. If you wish to have the downstream devices not generate alerts, they also need to be placed in maintenance mode.
