Step-by-Step
Procedure
To configure sFlow technology:
1.
Configure the IP address of the collector:
[edit protocols sflow]
user@switch#
set collector 10.204.32.46
NOTE: You can configure a maximum of 4 collectors.
2.
Configure the UDP port of the collector. The default UDP port assigned is 6343.
[edit protocols sflow]
user@switch#
set collector udp-port 5600
3.
Enable sFlow technology on a specific interface:
[edit protocols sflow]
user@switch#
set interfaces ge-0/0/0
NOTE: You cannot enable sFlow technology on a Layer 3 VLAN-tagged
interface.
You cannot enable sFlow technology on a link aggregation group (LAG)
interface--that is, an aggregated Ethernet interface with a name such
as ae0. You can enable sFlow technology on the member interfaces
that make up the LAG.
4.
Specify how often the sFlow agent polls the interface:
[edit protocols sflow]
user@switch#
set polling-interval 20
NOTE: The polling interval can be specified as a global parameter also.
Specify 0 if you do not want to poll the interface.
5.
Specify the rate at which packets must be sampled:
[edit protocols sflow]
user@switch#
set sample-rate 1000
Results Check the results of the configuration:
[edit protocols sflow]
user@switch# show
polling-interval 20;
