When I issue the command, show mls netflow usage, I saw this output, Netflow table usage notification disabled?
So how do I turn on this feature?

Use the following commands.
mls netflow
This enables NetFlow on the supervisor.
mls nde sender version 7
mls aging long 64
This breaks the long standing flows into one-minute segments.
mls aging normal 32
This ensures that flows that have finished are exported in a timely manner.
mls flow ip interface-full
mls nde interface
If you have Supervisor Engine 720, you need to execute the above two commands to put the interface information in the netflow packets.
ip flow ingress layer2-switched vlan
ip flow export layer2-switched vlan
The above two commands will help to enable NetFlow data export on PFC.
Apart from this please configure the routing module (MSFC) to enable netflow data export.(ip route-cache flow - on all interfaces)

Hello,
try the following command:
mls netflow usage notify 75 180
(Catalyst send a waring to the sylog when
TCAM is over 75% during the last 180 seconds...)
I hope that it helps...
Kind regards

I am sorry, I thought NetFlow export was disabled. I have not read the question correctly.
