Wireless management vlan

i was realy happy we finaly got this feature on the EPMP.

but im having a problem.

the wireless vlan management interface falls asleep, it doesnt send any data and therefore i cant reach it after a while.

it seems to dissappear from the ap bridge, because if i ssh to the SM on its public ip and do a ping through the management network, it wakes up

the SM's that seem to have this problem is in NAT mode
