Sample configuration for Cisco Catalyst 6800

This article provides a sample configuration for Cisco Catalyst 6800 series switch.

Legend:

• xx.xx.xx.xx  is your destination collector ( Orion)
• VLAN 1 is where the data will come from (any VLAN used for management or interface will also work)
• Port 2055 is for NetFlow v9
• Port 2070 is for NetFlow v5
   

Below is a sample configuration for Cisco Catalyst 6800 switch. For details, see the Cisco Catalyst 6800 Series Switches home page on the Cisco website. 
 

1. Execute the following commands:

   flow exporter NFexporter
   destination XX.XX.XX.XX             
   source Vlan 1
   transport udp 2055
   !
   
   flow monitor NFmonitor
   exporter NFexporter

2. Add the flow records for Orion.
   Note:  This step can be removed if the collector accepts the data as Cisco default. Otherwise, you will need to call TAC to help you modify this part. This will only work for Cisco CAT 6800.

   flow record NFrecord
   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

3. Add the flow record:

   flow monitor NFmonitor
   record NFrecord

4. Add the interfaces you need to add NetFlow to:

   interface TenGigabitEthernet1/1
   ip flow monitor NFmonitor input
   ip flow monitor NFmonitor output
   
   !
   
   
   !
   interface TenGigabitEthernet2/1
   
   ip flow monitor NFmonitor input
   ip flow monitor NFmonitor output
