Quick Steps for Configuring sFlow
Follow the steps below to create an sFlow receiver session.
1
To create a sFlow receiver session, use the sflow receiver command by entering sflow
receiver , followed by the receiver index, name, and the IP address. 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 32-29 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 Rate Sample-Header-Size
