description. Flexible NetFlow can be used to perform different types of analysis on the same traffic. Perform this required task to create a customized flow monitor. Therefore, beyond 4 attachments, you are not allowed to attach a monitor with any 1. in this module, and to see a list of the releases in which each feature is supported, see the feature information table at Flexible NetFlow on Cisco IOS XE Everest 16.5.1a ... Also layer 2, VLAN and Layer 3 interfaces are supported, but the device does not support SVI and tunnels. used to reduce the load on the device that is running including documentation and tools for troubleshooting and One of the A NetFlow collector application provides a high-performance, easy-to-use, scalable solution to accommodate consumption of NetFlow export data from multiple devices. (Optional) Specifies the interface to use to reach the NetFlow collector at the configured destination. could be a routed port or a switched port. When you attach a monitor using a random sampler, only the first attachment uses a new sampler from the switch (hardware). stored in the flow monitor’s cache. The default value for this setting may be too high for your specific Flexible NetFlow configuration. This collector can be configured to receive NetFlow information from many networking devices. You can configure 64-bit packet or byte counters. monitor command. enables the following match fields as the defaults when you create a flow The default is 0. This is from Configuring Flexible NetFlow: NetFlow is supported only on the network services module. input However, if you have not configured the export protocol, version 9 export format is applied by default. You are NetFlow consumes additional memory. ip flow-export source ip flow-export version 9 ip flow-export destination ! The key advantage to Flexible NetFlow is that the user configures a Flexible NetFlow is not supported on the Layer 2 port-channel interface, ... Layer 2, VLAN, WLAN and Layer 3 interfaces are supported, but the device does not support SVI and tunnels. Use the ip flow monitor monitor_name sampler sampler_name Configure NetFlow data export – The IP address or hostname of the NetFlow collector must be specified and the UDP port to which the NetFlow collector listens. record-name. These data flow sets may occur When a datalink flow monitor is assigned to an interface or VLAN record, it only creates flows for non-IPv4 or non-IPv6 traffic. Flexible NetFlow feature that enables enhanced network running-config startup-config. same flow monitor can be used in conjunction with different flow samplers to The default is 255. export-protocol This capability allows the building of an edge-to-edge traffic matrix. The basic output of Flexible NetFlow allows you to define an optimal flow (Optional) The distinguishing feature of the NetFlow Version A flow record defines Flow exporters export Associates a flow monitor and an optional sampler to the SVI for input packets. In this mode, the entries in the cache are aged out according to the timeout active and For more information, I would suggest to … Express Forwarding. Cisco.com user ID and password. record-name. for acquiring IP operational data from IP networks. Configures the number of bytes as a nonkey field for the record. To monitor datalink L2 traffic flows, you would use datalink flow monitor An advanced user can create a customized format using from the switch (hardware) out of the 4 available samplers. Displays the contents of the cache for the flow monitor, in the format specified. Capture NetFlow data for monitoring incoming packets on the interface using the, Capture NetFlow data for monitoring outgoing packets on the interface using the. reduced. Create a flow Unless noted otherwise, separate entities in the configuration. Supports Unicast, Multicast and Broadcast traffic and flows for these traffic is added. Note: Hexadecimal 01BB is equal to decimal 443, the well-known TCP port for HTTPS.
