This looks like the VLAN interface is going up/down in operational state. If there are no interface (and no clients) in a specific VLAN, the VLAN will go 'operationally down'. What you can do is set the VLAN state to 'operstate up'. I think this can be only done from the CLI:
(MM01) [] (config) #interface vlan 1
(MM01) ^[] (config-submode)#operstate
operstate Interface Operation state
(MM01) ^[] (config-submode)#operstate up
That will keep the VLAN 'up' regardless if there are interfaces or clients in the VLAN.

Subject: Alerts Interface flapping
Hello fellow AirHeads!!
I have an issue where I'm getting alerts for an interface flapping in quick secession. When looking at all the interfaces in the MM cli there are no interfaces flapping in the logs. Also, the show network cmd doesn't display any data.
My question is, how can I use the only information the alert gives me, the ifindex, to find the actual interface that is trigging the alert? The current version is 8.2.13.0
