Use the cache timeout parameter to define an active or inactive timeout for the flow monitor. Name of the flow monitor, up to 64 characters. The flow exporters associated with the monitor then export data from theįlow cache to the flow exporter destination. The network traffic on the interface and stores it in the flow cache in a format defined by the flow record. A flow monitor configuration consists of a flow record, a flow cache, and The fields exported are based on the NetFlow Version 9 Flow-Record Format.A flow monitor is the part of the IP Flow Information Export (IPFIX) feature that performs network monitoring for the selected interface. Outgoing counter with length N x 8 bits for the number of packets associated with an IP Flow.Incoming counter with length N x 8 bits for the number of packets associated with an IP Flow.

Outgoing counter with length N x 8 bits for the number of bytes associated with an IP Flow.Incoming counter with length N x 8 bits for the number of bytes associated with an IP Flow.

TCP/UDP destination port number i.e.: FTP, Telnet, or equivalent.

TCP/UDP source port number i.e.: FTP, Telnet, or equivalent.

Data fields that an MX or Z-Series will export via NetFlow are: In NetFlow v9 the NetFlow exporter sends a schema outlining the fields that will be be included in subsequent NetFlow flow updates. One of the new NetFlow version 9 features is the use of templates. In this use case, Dashboard networks across a wide number of different Dashboard organizations can export NetFlow data to a common server for centralized traffic analysis and monitoring within a network operations center. In some cases, customers may have a very large number of managed networks, also distributed across many distinct Dashboard organizations.

Traffic analysis across a large number of Dashboard networks and organizations - The Cisco Meraki Dashboard provides a large suite of traffic analysis information and summary reports across multiple networks or for an entire Dashboard organization.NetFlow can subsequently be used to aggregate traffic data for both Cisco IOS and Meraki MX/Z-Series devices at a given location. Mixed Meraki & Cisco Deployments - NetFlow is supported within Cisco IOS on a large number of Cisco products.Services and applications that serve as NetFlow collectors are designed to receive the NetFlow data sent from exporters, aggregate the information, and provide data visualization and exploration toolsets.Įxporting NetFlow data about traffic on an MX or Z-Series network can be useful in a variety of scenarios, including the following: NetFlow data is sent from a flow exporter to a flow collector. NetFlow is a protocol for exporting metrics for IP traffic flows.
