We are using cisco ASA in multi-context mode. So we have created two port-channels and 2 ports are assigned to each port-channel, then we have created sub interfaces of port channel and have assigned them to multi-context ASA. We can configure netflow under each context but what we are looking for is to configure netflow under system context so that we can see total amount of traffic hitting on the port-channels other than traffic hitting on port-channel sub interfaces under each context.

Please let me know if this is possible, any help will be highly appreciated.

Thanks,

LD
