Transport Udp Load-Share (Netflow-Lite Exporter Submode) - Cisco Catalyst 4500 Series Command Reference Manual

transport udp load-share (netflow-lite exporter submode)

transport udp load-share (netflow-lite exporter submode)
NetFlow-lite is only supported on the Catalyst 4948E and Catalyst 4948E-F Ethernet switches.
Note
To specify the number of destination ports to load balance on for a NetFlow-lite collector, use the
transport udp load-share command. To delete a transport UDP, use the no form of this command.
Syntax Description

Defaults 1
Command Modes

Usage Guidelines The CLI for UDP destination port load sharing allows you leverage multiple receive packet queues in
current server NICs, where the collector is running. This is an optional parameter. When number >= 2
is configured, a switch exports datagrams with a UDP destination port number that "round robins"
between a set of consecutive destination UDP port numbers starting with the base udp port number and
ending with base udp port number + num ports-1. Typically, netflow templates are sent on the base UDP
port number and the packet sample netflow records are sent on the remaining UDP ports. So, the
collector provides optimized processing for templates or metadata and packet sample records on a
socket.
Examples This example shows how to specify a UDP transport destination port for a NetFlow-lite collector:
Switch# config terminal
Switch(config)# netflow-lite exporter exporter1
Switch(config-netflow-lite-exporter)# destination 5.5.5.6
Switch(config-netflow-lite-exporter)# source 5.5.5.5
Switch(config-netflow-lite-exporter)# transport udp 8188
Switch(config-netflow-lite-exporter)# transport udp load-share
Switch(config-netflow-lite-exporter)# ttl 128
Switch(config-netflow-lite-exporter)# cos 7
Switch(config-netflow-lite-exporter)# dscp 32
Switch(config-netflow-lite-exporter)# template data timeout 1
Switch(config-netflow-lite-exporter)# options sampler-table timeout 1
Switch(config-netflow-lite-exporter)# options interface-table timeout 1
