Cisco Cisco ASA for Nexus 1000V Series Switch

The destination keyword indicates that a NSEL collector is being configured. The interface-name 
argument is the name of the ASA and ASA Services Module interface through which the collector is 
reached. The ipv4-address argument is the IP address of the machine running the collector application. 
The hostname argument is the destination IP address or name of the collector. The udp-port argument is 
the UDP port number to which NetFlow packets are sent. 

You can configure a maximum of five collectors. After a collector is configured, template records are 
automatically sent to all configured NSEL collectors.

Make sure that collector applications use the Event Time field to correlate events. 

Repeat the first step to configure more collectors.

To configure flow-export actions through Modular Policy Framework, perform the following steps:

Define the class map that identifies traffic for which NSEL events need to be exported. 

Example:

ciscoasa(config-pmap)# class-map flow_export_class

The flow_export_class argument is the name of the class map.

Choose one of the following options:

Configure the ACL to match specific traffic. 

Example:

ciscoasa(config-cmap)# match access-list flow_export_acl

The flow_export_acl argument is the name of the ACL.

Match any traffic.

Example:

ciscoasa(config-cmap)# match any

Define the policy map to apply flow-export actions to the defined classes.

Example:

ciscoasa(config)# policy-map flow_export_policy
