Device>Configure> Multi-Layer Switching>NetFlow Data Export

Use the NetFlow Data Export feature to filter criteria and export netflow data for analysis at a specified host running the NFFC or NF Collector application.

Filters for Netflow Data Export:

Destination IP Address (cseNetflowLSExportDataDest)

The destination network address in the NetFlow LAN for switching traffic data.

Destination Netmask (cseNetflowLSExportDataDestMask)

The IP subnet mask to be applied to its corresponding destination IP address.

Destination Port Number (this variable is a subset of the Destination IP Address (cseNetflowLSExportDataDest) MIB)

The destination port number in the NetFlow LAN for switching traffic data.

Source IP Address (cseNetflowLSExportDataSource)

The source network address in the NetFlow LAN for switching traffic data.

Source Netmask (cseNetflowLSExportDataSourceMask)

The IP subnet mask to be applied to its corresponding source IP address.

Source Port Number (this variable is a subset of the source IP address (cseNetflowLSExportSourcePort) MIB)

The source port number in the NetFlow LAN for switching traffic data.

Destination Host:

Netflow Data Export (cseNetflowLSExportStatus)

The status of the Netflow LAN Switching data export feature; enabled or disabled.

Host IP Address (cseNetflowLSExportHost)

The network IP address of the host to which Netflow LAN Switching statistics are exported.

IP Transport Number (cseNetflowLSExportTransportNumber)

The UDP port number to be used for exporting the Netflow LAN Switching statistics.

Command Line Alternative:

You can use the CLI command line (via the Telnet button in CiscoView’s button bar) to enable the NetFlow data export feature, to specify the filter criteria, and to name the destination host for exported NetFlow traffic data.

To specify filter criteria for the data to be exported, use:

set mls ne flow [destination <ip_addr_spec>] [source <ip_addr_space>] [src_port <port_number>] [dst_port <port_number>]

To enable or disable the Netflow Data Export feature , use:

set mls nde <disable|enable>.

To specify the destination host to which data is exported, use:

set mls nde <host_ip|host_name><port_number>.
