samples sent to the sFlow Collector. Under heavy load, this sample loss could be significant and
could therefore affect the accuracy of the sampling analysis.
Example Configuration
The general procedure for configuring sFlow includes:
1. Configure your sFlow Collector information to be used by the sFlow Agent on the switch. Up
to eight Collectors can be configured. The information is stored in the sFlowReceiverTable.
2. Enable and configure sFlow packet flow sampling instances on each port.
3. Enable and configure sFlow counter sampling poller instances on each port.
The following is an example of the commands used to configure sFlow:
# configure sFlow Collector 1
# accept defaults for datagram size and port
set sflow receiver 1 owner enterasys timeout 180000
set sflow receiver 1 ip 192.168.16.91
#
#configure packet sampling instances on ports 1 through 12
#assign to sFlow Collector 1
set sflow port ge.1.1-12 sampler 1
set sflow port ge.1.1-12 sampler maxheadersize 256
set sflow port ge.1.1-12 sampler rate 2048
#
#configure counter poller instances on ports 1 through 12
#assign to sFlow Collector 1
set sflow port ge.1.1-12 poller 1
set sflow port ge.1.1-12 poller interval 20
