sflow agent
Use sflow agent to configure an IP address for the sFlow agent.
Use undo sflow agent to remove the configured IP address.
Syntax
sflow agent { ip ip-address | ipv6 ipv6-address }
undo sflow agent { ip | ipv6 }
Default
No IP address is configured for the sFlow agent. 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 IP address for it. However, the device does not save the automatically selected IP address in the configuration file.

Usage guidelines
HP recommends that you manually configure an IP address for the sFlow agent.
Only one IP address can be specified for the sFlow agent on the device.
Examples
# Specify IP address 10.10.10.1 for the sFlow agent.
<Sysname> system-view
[Sysname] sflow agent ip 10.10.10.1

Default command level
2: System level
Parameters
collector-id: Specifies an ID for the sFlow collector. You can configure up to 10 sFlow collectors.
ip ip-address: Specifies an IPv4 address for the sFlow collector.
ipv6 ipv6-address: Specifies an IPv6 address for the sFlow collector.
description text: Configures a description for the sFlow collector. The default description is "CLI Collector."
datagram-size size: Specifies the maximum length of the sFlow data portion in an sFlow packet. The value ranges from 200 to 3000 bytes and defaults to 1400 bytes.
port port-number: Specifies the port number of the sFlow collector, in the range of 1 to 65535. The default port number is 6343.
time-out seconds: Specifies the aging time of the sFlow collector, in the range of 1 to 2147483647, in seconds. When the aging time expires, all the settings of the sFlow collector are restored to the default. For an sFlow collector with the aging timer configured, the system does not save its configuration in the configuration file. By default, the sFlow collector never ages out.
Examples
# Specify the following parameters for sFlow collector 2:
· Destination IP address: 3.3.3.1.
· Port number: The default.
· Description: netserver.
· Aging time: 1200 seconds.

Views
Interface view
Default command 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 samples packets as follows:
· Randomly samples a packet, like the 10th packet, from the first 4000 packets.
· Samples the 4010th packet the next time, and so on.
random: Specifies the random sampling mode. For example, if the packet sampling interval is set to 4000, the device might randomly sample packets as follows:
· One packet from the first 4000 packets.
· Two from the next 4000 packets.
· None from the third 4000 packets.
However, the device generally samples one packet from 4000 packets on the average.
Usage guidelines
This command is supported only on Ethernet and WLAN-ESS interfaces, instead of logical interfaces (Ethernet subinterfaces and VLAN interfaces) and network management interfaces.
Examples
# Specify the fixed sample mode on WLAN-ESS 1.
<Sysname> system-view
[Sysname] interface WLAN-ESS 1
[Sysname-WLAN-ESS1] sflow sampling-mode determine

sflow sampling-rate
sflow sampling-rate
Use sflow sampling-rate to specify the number of packets out of which flow sampling will sample one packet on an interface.

undo sflow sampling-rate
Default

Default command level
2: System level
Parameters
interval: Specifies the number of packets out of which flow sampling will sample one packet on the interface. The value range for this argument is 1000 to 5000.
Usage guidelines
This command is supported only on Ethernet interfaces, instead of logical interfaces (such as Ethernet subinterfaces and VLAN interfaces) and network management interfaces.
The bigger the value of the interval argument, the lower the sampling rate.
Examples
# Configure WLAN-ESS 1 to sample one packet out of 4000 packets.
<Sysname> system-view
[Sysname] interface WLAN-ESS 1
[Sysname-WLAN-ESS1] sflow sampling-rate 4000

Default
No source IP address is specified for sFlow packets.
