Configuring flow sampling – H3C Technologies H3C MSR 50 User Manual
Page 164

Step Command
Remarks
Not specified by default. The device periodically checks
whether the sFlow agent has an IP 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 IP address.
389.
Configure an
IP address for
the sFlow
agent.
sflow agent { ip ip-address |
ipv6 ipv6-address }
NOTE:
•
H3C recommends that you configure an IP address
manually for the sFlow agent.
•
Only one IP address can be specified for the sFlow
agent on the device.
sflow collector collector-id
{ { ip ip-address | ipv6
ipv6-address } |

description text | port
port-number | time-out
seconds } *
By default, the device presets a certain number of sFlow
collectors.
390.
Configure the
sFlow
collector
information.
Use the display sflow command to display the
parameters of the preset sFlow collectors.
Optional.
391.
Specify the
sFlow version. sflow version { 4 | 5 }
The default sFlow version is 5.
392.
Specify the
source IP
address of
sFlow
packets.
Optional.
sflow source { ip ip-address |
ipv6 ipv6-address } *
Not specified by default.

Specify the number of packets
out of which flow sampling
samples a packet on the
interface.
sflow sampling-rate rate
Required.
Optional.
397.
Set the maximum number of
bytes of a packet (starting
from the packet header) that
flow sampling can copy.
The default setting is 128 bytes.
H3C recommends that you use the
default value.

Specify the sFlow collector for
flow sampling.
No collector is specified for flow
sampling by default.
