Cisco Cisco ASA for Nexus 1000V Series Switch

Each ASA node in the cluster establishes its own connection to the NetFlow collector(s) and advertises 
its templates independently. The collector uses the source IP address and source port of the packet to 
differentiate between the NetFlow exporters. 

To decode some of the field values that the ASA populates, direct interaction with the device may be 
required. We recommend that you use a dynamic mechanism such as expect scripts to obtain the required 
information from the CLI of the device that issued the event. 

The device supports console, Telnet, and SSH secure shell access; however, SSH is the recommended 
method because of performance and security. 

You can also decode the Interface ID fields using SNMP GET requests from the device interface MIB. 
This is the only field that has MIB support.

You may use the show interface detail command to obtain a list of all the interfaces on the device. This 
output includes a line under each interface that corresponds to the Interface ID value sent in the NetFlow 
fields. In the following example, the interface number is 8.
