Netflow Analyzer with Cisco Sup2T

Netflow Analyzer with Cisco Sup2T

Hello,

 

we have on a VSS seven ethernet Layer 3 connections (OSPF) to our branch offices. As the Sup2T has improved netflow capabilities we have following configuration:

 

 

flow record CORE-FLOW

match ipv4 source address

match ipv4 destination address

match transport source-port

match transport destination-port

match flow direction

collect counter bytes

collect counter packets

collect timestamp sys-uptime first

collect timestamp sys-uptime last

!

!

flow exporter NETMANAG

destination 192.168.1.1

transport udp 9996

!

flow platform cache timeout fast

!

flow monitor CORE-MONITOR

record CORE-FLOW

exporter NETMANAG

 

 

interface GigabitEthernet2/3/1

description LAN 3856766

ip address xxx.xxx.xxx 255.255.255.252

ip flow monitor FLOW-MONITOR input

ip flow monitor FLOW-MONITOR output

ip ospf dead-interval 15

interface GigabitEthernet2/3/7

description LAN 3856773

  no switchport

ip address xxx.xxx.xxx 255.255.255.252

ip flow monitor FLOW-MONITOR input

ip flow monitor FLOW-MONITOR output

 

 

We use the NetFlow Analzer 9.6 Professional. There are two problems with the flows from this VSS:

 

1. All flows are being displayed as a single Interface (IfIndex-1) and not 7 separately interfaces.

2. The flows from the VSS are only ingress no egress flows are recorded

 

Is there something wrong with the configuration above?

 

Thank you.
