Examples This example shows how to specify a sampled header size:
Switch# config terminal
Switch(config)# netflow-lite sampler sampler1
Switch(config-netflow-lite-sampler)# packet-rate 32
Switch(config-netflow-lite-sampler)# packet-section size 128
Switch(config-netflow-lite-sampler)# packet-offset 16
Switch(config-netflow-lite-sampler)# exit
Switch(config)# exit
Switch#
Switch# show netflow-lite sampler sampler1
Netflow-lite Sampler sampler1:
Id : 1
Packet Sampling rate: 1 out of 32
Packet Section Size: 64 bytes
Packet offset: 16 bytes
You can verify your settings with the show netflow-lite sampler privileged EXEC command.
