ENA can collect flow data from devices that use either 16-bit or 32-bit interface indexing.
ENA can also collect flow data from devices running the following supported flow versions:
- NetFlow v5.
- Sampled NetFlow v5.
- NetFlow v6.
- NetFlow v7.
- NetFlow v9, support for the most commonly used templates.
- Sampled NetFlow v9.
- IPFIX, comparable support to that delivered for NetFlow v9.
- Netstream v5.
- Netstream v9.
- sFlow v4.
- sFlow v5.
- JFlow, for Juniper.
- VMware NSX based flows containing VXLAN information.
ENA can receive JFlow, NetFlow and IPFIX on any port(s). By default, it listens on ports 2055 and 9996, because these are the default ports for those protocols. You can add new ports or change existing ports, so long as they don't conflict with other ports taken by other processes/applications. You can also delete some ports if you do not want the port to be used.
ENA can receive sFlow on port 6343 only. By default, it listens on this port. You can remove the receiver on this port number to disable sFlow receiving.
ENA supports NetFlow monitoring on Cisco ASA devices, dependent on the particular Cisco ASA version:
|Cisco ASA Version||ENA support|
ENA supports VMware NSX SDN flow monitoring (i.e. VXLAN overlays). You can break down VXLAN flow information in the Flow dashlet with general flow attributes, and the following specific attributes:
- Top Conversations (inside VXLAN)
- Top Applications (inside VXLAN)
- Top Ports (inside VXLAN)
- Top Hosts (inside VXLAN)
- Top Listeners (inside VXLAN)
- Top Talkers (inside VXLAN)
- Top Protocols (inside VXLAN)
