Dear Team,

Could you please share us the configuration guide for the NetFlow Router. The current configuration is as below:

 

flow record NETFLOW-RECORD-IN
match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match interface input
collect interface output
collect counter bytes long
collect counter packets long
collect timestamp sys-uptime first
collect timestamp sys-uptime last
!

NAME: "CISCO3945-CHASSIS", DESCR: "CISCO3945-CHASSIS"

flow record NETFLOW-RECORD-OUT
match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match interface input
collect interface output
collect counter bytes long
collect counter packets long

Second that, check the interface(s) configuration.    

Also wanted to point out, looks like your trying to do both a netflow inbound and outbound policy.   Best practices say to do "inbound" on all your interfaces rather than inbound and outbound on any one interface.   Not sure if that model does bidirectional netflow either.   But, doing both inbound and outbound on more than one interface will double some of your flows in NTA...
