netflow filter interface

Enables port-based netflow packet filtering.

netflow filter interface <name> <address> permit
 
        [ input-interface | output-interface ]
 
        [ <ifIndex> | <ifDescr> | <interface-address>
 

 
no netflow interface name> <address> permit
 
        [ input-interface | output-interface ]
 
        [ <ifIndex> | <ifDescr> | <interface-address>
 

 
no netflow interface
 

• name-- name of SNMP agent (see polling snmp-agent to see how you create this name on CNA)
• address--IP address (a.b.c.d format) of the device sending netflow to CNA
• ifIndex-- interface index
• ifDescr-- interface name
• interface-address-- ip address (a.b.c.d format) of the interface on the sending device

Must be in EFC configuration mode (config-efc), which requires privileged-level access.

Available for use multiple times in the configuration.

none

Use the netflow filter interface command to create netflow packet filters which will tell CNA to accept netflow packets from specific router/switch interfaces. If there are no filters specified for a particular device, then all packets will be accepted from that device. If there is at least one filter configured for a device, then netflow packets will be accepted from only the interfaces on that device which you have specified with this command.

If you specify ifIndex instead of ifDescr or interface-address then CNA will not need to query the sending device to determine the actual numbering of the interface. In this case, the SNMP agent name will not be used, and the output from show stat link-monitor will not include this filter since there is no need to SNMP poll to acquire the index.

Use the no form of the command to restore the default.
