Hi. We faced with this problem too.
What we have at this time:
1) Two 4500x in VSS.
SW-C4500X-CORE#sh switch virtual
Executing the command on VSS member switch role = VSS Active, id = 1
Switch mode : Virtual Switch

Local switch number : 1

Peer switch number : 2
Peer switch operational role : Virtual Switch Standby
Executing the command on VSS member switch role = VSS Standby, id = 2
Switch mode : Virtual Switch
Virtual switch domain number : 20
Local switch number : 2
Local switch operational role: Virtual Switch Standby
Peer switch number : 1
Peer switch operational role : Virtual Switch Active

2) We trying to get net-flow data about traffic using Flexible NetFlow.
Our FNF config looks like this
<...>
flow record r1
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
collect interface input
collect interface output
collect counter bytes
collect counter packets
!
!
flow exporter nfcoll
destination 192.168.6.52
transport udp 9996
!
!
flow monitor m1
exporter nfcoll
cache timeout active 60
record r1
!
!
<...>
interface TenGigabitEthernet2/2/1
no switchport
ip flow monitor m1 input
ip address 10.255.3.2 255.255.255.252
!
<...>
3) After that we prepare our netflow collector for recieving netflow data.
As a result we realized, that netflow data from interface Te2/2/1 is not exported.
And soon we realize that no flow data collected on interface, that belong to stanntdby switch.
Netwflow data collected on active switch interfcaces only.
More over when we try to view local netflow cache on active switch via CLI - we see nothing.
4) Also we try to view netflow status on standby box.
SW-C4500X-CORE#remote login module 11
Connecting to standby virtual console
Type "exit" or "quit" to end this session
SW-C4500X-CORE-standby-console#sh flow interface
SW-C4500X-CORE-standby-console#
So, as you can see: netflow monitor is not applied on our interface.
Now we trying to understand: is this a BUG or may be we incorrect configure netflow.
Please, somebody clarify this situation.
