This is true. But here is a scenario we are seeing. Here is our setup first.
Customer is on Vlan4 which is bridged to VLAN10. Both vlan's are on the sam=
e switch. If data is streaming in on vlan10 to the vlan4 bridge, then we sw=
itch the customer to vlan10, the streaming data will continue on to the bri=
dge server and the customer will not be able to transfer data until that st=
ream dies or if the timer just happens to be expiring for that MAC. So we n=
eed to clear the mac. I did a brctl setageing 3 to set the timer lower. But=
what effect could this have when I have some 50k to 100k mac's known by th=
e bridging server?

No API exists but the first transmit (gratuitous ARP?) would
move the entry.
