Chapter 61 Configuring NetFlow-lite
Display Commands
The system automatically determines the average packet size at an interface based on observation of
input traffic and uses that value in rate DBL sampling.
Valid range of packet sizes that can be used by the algorithm is 64 - 9216 bytes. A value of 0 is taken to
mean that automatic determination of average packet size is desired.
The sampler and exporter must be valid for packet sampling. If any mandatory parameters are missing,
a warning message indicating that sampler or exporter is invalid is displayed.
Display Commands
To view the configured value of the minimum mask, use the following commands for each aggregation
scheme, as needed:
The following example shows how to displays information about a sampler:
Switch# show netflow-lite sampler low-rate
Netflow-lite Sampler low-rate:
Description: Sampler
Sampling rate: 1 out of 256
Packet Section Size: 64 bytes
Packet offset: 0 bytes
The following example shows how to display information about a particular packet and per monitor stats
on a physical port:
Switch# show netflow-lite monitor 1 interface gi1/3
Interface GigabitEthernet1/3:
Netflow-lite Monitor-1:
Active: TRUE
Sampler: sampler1
Exporter: exporter1
Average Packet Size: 0
Statistics:
Packets exported: 0
Packets observed: 0
Packets dropped: 0
Command Purpose
Switch# show netflow-lite sampler
sampler_name
Displays information about a sampler.
Switch# show netflow-lite monitor monitor
interface interface_name
Switch# show netflow-lite monitor monitor
vlan vlan_id
The following commands display information
about a particular packet and per monitor stats.
The interface can be either a physical port or a
VLAN.
They display the following packet sampling
statistics:
• Total # of packet (samples) exported
• Total # of packet (samples) dropped due to
lack of local resources
• Total# of packets seen at the monitor
Switch# show netflow-lite exporter
exporter_nsme
Displays information about the collector and
global stats.
