Exactly. The docs say about the "ip flow export layer2-switched ..."
command:

"Before you use this command on Catalyst 6500 Series Switches that are
configured with Supervisor Engine 720, you must ensure that a
corresponding VLAN interface is available and has a valid IP address."

But hey, if that is it, then why didn't TAC point it out? ;-)
