Currently, only the sFlow agent function is supported on the device.
Operation of sFlow
sFlow operates as follows:
1) With sFlow enabled, a physical port encapsulates sampled data into packets and sends them to
the sFlow agent.
2) The sFlow agent periodically collects the statistics of all sFlow enabled ports.
3) When the sFlow packet buffer overflows or the one-second timer expires, the sFlow agent sends
sFlow packets to the specified sFlow collector.
Configuring sFlow
The sFlow feature enables the remote sFlow collector to monitor the network and analyze sFlow
packet statistics.
Follow these steps to configure sFlow:
To do… Use the command… Remarks
Enter system view system-view —
Specify the IP address of the
sFlow agent
sflow agent { ip ip-address | ipv6
ipv6-address }
Required
Not configured by default.
Specify the IP address and port
number of the sFlow collector
sflow collector { ip ip-address |
ipv6 ipv6-address } [ port
port-number ]
Required
Not specified by default.
Set the counter sampling interval
at which the sFlow agent collects
the statistics of sFlow enabled
ports
sflow interval interval-time
Optional
20 seconds by default.
Enter interface view

—
Enable sFlow in the inbound or
outbound direction
sflow enable { inbound |
outbound }
Required
Not enabled by default.
Specify the sFlow sampling mode
sflow sampling-mode
{ determine | random }
Optional
