The device periodically checks the existence of the sFlow agent address. If the sFlow agent has no IP address configured, the device automatically selects an interface IP address for the sFlow agent but does not save the selected IP address. NOTE: • HP recommends configuring an IP address manually for the sFlow agent. • Only one IP address can be specified for the sFlow agent on the device. By default, the device presets a number of sFlow collectors. Use the display sflow command to display the parameters of the preset sFlow collectors. Optional Not specified by default.

Configuring the sFlow agent and sFlow collector
Step
Command
Remarks
1.
Enter system
view.
system-view
N/A
2.
Specify the IP
address for the
sFlow agent.
sflow agent
{
ip
ip-address
|
ipv6
ipv6-address
}
Optional
Not specified by default. The device
periodically checks the existence of the sFlow
agent address. If the sFlow agent has no IP
address configured, the device automatically
selects an interface IP address for the sFlow
agent but does not save the selected IP address.
NOTE:
•
HP recommends configuring an IP address
manually for the sFlow agent.
•
Only one IP address can be specified for the
sFlow agent on the device.
3.
Configure the
sFlow collector.
sflow collector
collector-id
{ {
ip
ip-address
|
ipv6
ipv6-address
}
|
datagram-size
size
|
description
text
| port
port-number
|
time-out
seconds
} *
By default, the device presets a number of sFlow
collectors.
Use the
display sflow
command to display the
parameters of the preset sFlow collectors.
4.
Specify the
source IP
address of sent
sFlow packets.
sflow source
{
ip
ip-address
|
ipv6
ipv6-address
} *
Optional
Not specified by default.

by default.
4.
Set the interval for flow
sampling.
sflow sampling-rate
interval
Not set by default.
5.
Set the maximum copied
length of a sampled packet.
sflow flow max-header
length
Optional
By default, up to 128 bytes of a sampled
packet can be copied. You are
recommended to use the default value.
6.
Specify the sFlow collector for
flow sampling.
sflow flow collector
