Sflow Sampling-Rate - HP 6125G Command Reference Manual

Default level
2: System level
Parameters
determine: Specifies the fixed sampling mode. For example, if the flow sampling interval is set to 4000
(by using the sflow sampling-rate command), the device randomly samples a packet, like the tenth
packet, from the first 4000 packets. The next time the device samples the 4010th packet, and so on.
random: Specifies the random sampling mode. After the sampling interval is specified with the sflow
sampling-rate command, a device samples zero, one, or multiple packets from each group of sampled
packets. Generally, one packet is sampled from each group of sampled packets. For example, with the
packet sampling rate set to 4000, the device may sample one packet from the first 4000 packets, two
from the next 4000 packets, and none from the third 4000 packets, but generally the device samples one
packet from 4000 packets.
Description
Use sflow sampling-mode to specify the packet sampling mode.
Use undo sflow sampling-mode to restore the default.
The default mode is random.
This command is supported only on physical Ethernet interfaces, but not on logical interfaces (such as
VLAN interfaces).
Related commands: sflow sampling-rate.
NOTE:
The switch does not support the flow sampling mode determine.
