Configuring the sFlow agent and sFlow collector
information
Step Command Remarks
1. Enter system view.
system-view
N/A
2. (Optional.)
Configure an IP
address for the
sFlow agent.
sflow agent
{
ip
ip-address |
ipv6
ipv6-address }
By default, no IP address is configured for the
sFlow agent. The device periodically checks
whether the sFlow agent has an IP address. If
not, the device automatically selects an IPv4
address for the sFlow agent but does not save
the IPv4 address in the configuration file.
NOTE:
• As a best practice, manually configure an IP
address for the sFlow agent.
• Only one IP address can be configured for
the sFlow agent on the device, and a newly
configured IP address overwrites the
existing one.
3. Configure the
sFlow collector
information.

[
vpn-instance
vpn-instance-name
] {
ip
ip-address |
ipv6
ipv6-address }

By default, no sFlow collector information is
configured.
4. (Optional.) Specify
the source IP
address of sFlow
packets.
sflow source
{
ip
ip-address
|
ipv6
ipv6-address } *
By default, the source IP address is determined
by routing.
Configuring flow sampling
Perform this task to configure flow sampling on an Ethernet interface. The sFlow agent performs the
following tasks:
1. Samples packets on that interface according to the configured parameters.
2. Encapsulates the packets into sFlow packets.
3. Encapsulates the sFlow packets in the UDP packets and sends the UDP packets to the
specified sFlow collector.
To configure flow sampling:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter Layer 2 Ethernet
interface view.
interface
interface-type
interface-number
N/A
3. (Optional.) Set the flow
sampling mode.
sflow sampling-mode
{
determine
|
random
}
The default setting is random.
The
determine
keyword is not
supported in the current software
version. It is reserved for future
support.
