Quick Steps for Configuring sFlow
Follow the steps below to create a sFlow receiver session.
1.      To create a sFlow receiver session, use the sflow agent command by entering sflow receiver, followed by the receiver index, name, and the address to be monitored. For example:
 
-> sflow receiver 1 name Golden address 198.206.181.3
 
2.     Optional. Configure optional parameters. For example, to specify the timeout value “65535” for sFlow receiver session on address 198.206.181.3, enter:
 
-> sflow receiver 1 name Golden address 198.206.181.3 timeout 65535
 
Note. Optional. To verify the sFlow receiver configuration, enter show sflow receiver, followed by the
sFlow receiver index. The display is similar to the one shown below:
 
-> show sflow receiver
Receiver 1
Name = Golden
Address = IP_V4 198.206.181.3
UDP Port = 6343
Timeout = 65535
Packet Size= 1400
DatagramVer= 5
For more information about this command, see “sFlow” on page 41-29 or the “sFlow Commands” chapter
in the OmniSwitch CLI Reference Guide.
 
Follow the steps below to create a sFlow sampler session.
1.     To create a sFlow sampler session, use the sflow sampler command by entering sflow sampler, followed by the instance ID, port list, receiver, and the rate. For example:
 
-> sflow sampler 1 2/1-5 receiver 1 rate 2048

 
2.     Optional. Configure optional parameters. For example, to specify the sample-hdr-size value “128” for sFlow sampler instance 1 on ports 2/1-5, enter:
 
-> sflow sampler 1 2/1-5 receiver 1 rate 2048 sample-hdr-size 128
 
Note. Optional. To verify the sFlow sampler configuration, enter show sflow sampler, followed by the
sFlow sampler instance ID. The display is similar to the one shown below:
 
-> show sflow sampler 1
 
Instance      Interface     Receiver      Sample-rate   Sample-hdr-size
---------------------------------------------------------------------
1             2/ 1          1             2048          128
1             2/ 2          1             2048          128
1             2/ 3          1             2048          128
1             2/ 4          1             2048          128
1             2/ 5          1             2048          128
 
For more information about this command, see “sFlow” on page 41-29 or the “sFlow Commands” chapter
in the OmniSwitch CLI Reference Guide.
 
Follow the steps below to create a sFlow poller session.
 
1.     To create a sFlow poller session, use the sflow poller command by entering sflow poller, followed by the instance ID, port list, receiver, and the interval. For example:
 
-> sflow poller 1 2/6-10 receiver 1 interval 30
 
Note. Optional. To verify the sFlow poller configuration, enter show sflow poller, followed by the sFlow poller instance ID. The display is similar to the one shown below:\
 
-> show sflow poller
Instance Interface Receiver Interval
-------------------------------------------
1        2/ 6      1        30
1        2/ 7      1        30
1        2/ 8      1        30
1        2/ 9      1        30
1        2/ 10     1        30
