Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 528)

For complete information on the sFlow CLI commands for the Brocade switch, refer to the Network OS
Command Reference.
To configure sFlow globally, perform the following steps in global configuration mode.
1. Enter the configure terminal command to change to global configuration mode.
switch# configure terminal
2. Globally enable the sFlow protocol.
switch(config)# sflow enable
3. Designate the IP address (up to five addresses) for the sFlow collector server. Optionally, you can
designate the port number.
NOTE
Both IPv4 and IPv6 addresses are supported. However, each address must be entered individually
by means of a separate sflow collector command.
switch(config)# sflow collector 10.10.138.176 6343
switch(config)# sflow collector fd00::1900:4545:3:200:f8ff:fe21:67cf port 6343
switch(config)# sflow collector fd00::200:f8ff:fe21:67cf
4. Set the sFlow polling interval (in seconds).
switch(config)# sflow polling-interval 35
5. Set the sFlow sample-rate.
switch(config)# sflow sample-rate 4096
6. Return to privileged EXEC mode.
switch(config)# end
7. Confirm the sFlow configuration status by using the show sflow or show sflow all commands.
switch# show sflow
sFlow services are: enabled
Global default sampling rate: 32768 pkts
Global default counter polling interval: 20 secs
Collector server address Number of samples sent
------------------------ --------------------------------
fd00::1900:4545:3:200:f8ff:fe21:67cf 0
fd00::200:f8ff:fe21:67cf 0
10.10.138.176 0
switch# show sflow all
sFlow services are: enabled
Global default sampling rate: 32768 pkts
Global default counter polling interval: 20 secs
Collector server address Number of samples sent
------------------------ --------------------------------
fd00::1900:4545:3:200:f8ff:fe21:67cf:6343 0
fd00:fd00::200:f8ff:fe21:67cf: 0
10.10.138.176: 6343 0
8. Clear any existing sFlow statistics to ensure accurate readings.
switch# clear sflow statistics
Configuring sFlow for interfaces
After the global sFlow configuration, sFlow must be explicitly enabled on all the required interface
ports.
NOTE
When sFlow is enabled on an interface port, it inherits the sampling rate and polling interval from the
global sFlow configuration.
