Netflow Analyzer doesn't work after vlan changed

Hi All,

firstly, my english is poor, i'm sorry...

we have use netflow analyzer since 2007.
last day our ISP change our vlan ID. then netflow doesnt work.

we have a cisco 6509.

our config: (before change)

ip flow-cache timeout active 1
ip flow ingress layer2-switched vlan 3-4,6,9-16,18-22,24-28,33,36,51,100-102,108-121,152
mls ip multicast flow-stat-timer 9
mls aging long 64
mls aging normal 32
mls flow ip interface-full
no mls flow ipv6

interface Vlan116
description XXX
ip address XXX.xxx.xxx
ip route-cache flow

ip flow-export source Vlan116
ip flow-export version 9
ip flow-export destination xxx.xxx.xxx.xxx 9800
no ip http server

our config (after change)

ip flow-cache timeout active 1
ip flow ingress layer2-switched vlan 3-4,6,9-16,18-22,24-28,33,36,51,100-102,108-115,117-121,152,160
mls ip multicast flow-stat-timer 9
mls aging long 64
mls aging normal 32
mls flow ip interface-full
no mls flow ipv6

interface Vlan160
description XXX
ip address XXX.xxx.xxx
ip route-cache flow

ip flow-export source Vlan160
ip flow-export version 9
ip flow-export destination xxx.xxx.xxx.xxx 9800
no ip http server

no server change, no IOS change, no port change, only vlan ID change.

in netflow analyzer dashboard graph doesnt work.

what can i do?

thans for all
