The clue is inside your cut'n'paste from the output:

" Actual flows can be seen on line cards only
  Do "attach <slot>" and re-enter the show command
"

so do either:

	attach 2 (if the card is in slot 2)
	show ip ca flow

or (encouraged):

	execute-on slot 2 show ip ca flow

then u get the right information you are looking for
