sflow-create

This command is used to create an sFlow Agent on the network. You can configure an sFlow Agent with a scope local only (on the local switch).

Syntax   sflow-create

name name-string

Specify a name for the sFlow.

type ingress|egress

Specify the type of packet for the sflow Agent. Specify ingress to capture incoming packets, and egress for outgoing packets.

sample-type raw|cooked

Specify the sample type for the sFlow Agent. Raw indicates that the packet retains the link level header, and cooked indicates that link level header is removed.

ports port-list

Specify the list of ports to capture packets.

sample-rate 256-16000

Specify the sFlow sample rate. The value ranges from 256-16000, and the default value is 4096.  Enter zero (0) if you want to disable sFlow sampling.

counter-polling-interval 0..120

Specify the sFlow interface statistics for counter polling interval.  This is the periodic sampling or polling counters associated with a data source.

trunc-length trunc-length-number

Specify the truncated length of the captured packet.

agent-id ip-address

Specify the IP address of the sFlow agent.

Note: While creating the sFlow, do not configure both the sample-rate, and counter-polling-interval to zero (0). If you do so, an error message: sflow-create: Sample-rate/counter-polling-interval both can't be 0 is displayed. However, later, you can change both values to zero (0) using the sflow-modify command if desired.

When you configure the sample-rate, and counter-polling-interval to zero (0) using the sflow-modify command, then no packets are sent out for sFlow monitoring.

Defaults   The sample-rate default value is 4096.

Usage   sFlow Agents capture packets on the network, and send them to the sFlow Collector for analysis. Use this command to configure an sFlow Agent.

Examples  To configure an sFlow Agent, SF-agent1, with the sample type raw on ports 21-25, use the following command:
