    Enabling Netflow in Cisco 6509 Switch on physical interface????


      Hi All,

      I have managed to succesfully enable NetFlow on our Cisco 6509 switch and are monitoring network traffic only between VLANs.


      We currently have a LAN extension whereby I would like to monitor via NTA what sort of traffic is going down that link.


      I have tried to enable Netflow on the Physical GigabiEthernet port but the cisco switch does not allow me to enter a Gigabit Ethernet port but only VLANs?


      Is this a limitation on the cisco switch or am I just missing something? Please note that the LANExtension is in a VLAN that is being monitored but when you drill down in NTA on the specific port, its does not really show specific information I am looking for.


      Any ideas?
