Hello,
How can I monitor each port of an EtherSwitch?
I've already tried but, i have no result:
I've configured all ports into a VLAN1.
I've configured an IP Address for the card : Vlan1
So all PC or router connected in the EtherSwitch are in a same VLAN / LAN.
But when I monitor the router with the Netflow Analyzer, I cannot see the 16 ports of the EtherSwitch.
I just see the interface Vlan1.
But I want to monitor each port of the EtherSwitch.
Can you help me?
Many Thanks

Hello.
Please, which box do you using and which version, CatOS, IOS or Native IOS? Could you send me your netflow configuration? Did you also configure mls nde? Did you configure layer2-switched accounting?
For IOSes try the command:
ip flow ingress layer2-switched vlan
ip flow export layer2-switched vlan
However, from the IOS guide: A PFC3B or PFC3BXL running 12.2(18)SXE or higher is required for this command, which enables NDE for all traffic within the specified VLANs rather than just inter-VLAN traffic.
If you are using a CatOS you may use the following command:
set mls bridged-flow-statistics enable
Kind regards

Hello,
Thanks for the reply.
I'm using a 3825 with an IOS c3825-advipservicesk9-mz.124-11.T2
This is my Netflow configuration i've put into the router :
!!__________________________
!!
ip flow-cache entries 9996
ip flow-export source Vlan2
ip flow-export version 5
ip flow-export destination 192.168.0.52 9996
!! 192.168.0.52 is the PC monitor.
!!______________________________
I cannot put the "ip route-cache flow" command
into each port of the EtherSwitch.
I've tried your solution, but ios have not this command :
ip flow ingress layer2-switched
The following are possible on with this IOS
ip flow-aggregation
ip flow-cache
ip flow-capture
ip flow-egress
ip flow-export
ip flow-top-talkers
Many thanks
