Just to note -- The maintenance mode DOES roll down to the interface without this setting enabled.
Please be careful and take note of performance if you enable this as this adds maintenance alarms to the database for the interfaces. If you have maintenance alarms enabled and you utilize this option on many devices with lots of interfaces, you may create a performance problem due to the amount of maintenance alarms.
Just to give an example, if I have a router with 200 interfaces and I do NOT use this setting, when I put the device into maintenance mode, there is 1 maintenance alarm. With this setting on, there will be 201 maintenance alarms.
Thanks for the clarification.
If maintenance mode does roll down to Interfaces, then what is the purpose of this "rollMMAlarmToIF" attribute?
When would someone need/want to have this ON?
It’s more of a visual thing. So if you happen to be looking at the interface in a GC, upon first/quick glance you may not realize it’s in MM. Using that setting turns the icon brown, so that it’s more obvious (but in turn, it creates an alarm). ☺
