Netflow module on 4506


i've installed a netflow card, WS-F4531, on one of my 4506 switches but i'm not getting the reports i expected

the card is installed ok and all the commands are correct (so i'm told)

i'm using 3rd party software from crannog software to report the exported results

my problem:

i was expecting the same results as i get from my routers, i.e. per interface details but with the switch all i'm getting is per vlan and as i only run a single vlan on this switch the results mean little

has anyone tried this themselves and resolved it?

many thanks to anyone taking the time to reply
