community.network.ce_sflow module – Manages sFlow configuration on HUAWEI CloudEngine switches.

Note

This module is part of the community.network collection (version 5.0.2).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.network.

To use it in a playbook, specify: community.network.ce_sflow.

Synopsis

  • Configure Sampled Flow (sFlow) to monitor traffic on an interface in real time, detect abnormal traffic, and locate the source of attack traffic, ensuring stable running of the network.

Aliases: network.cloudengine.ce_sflow

Parameters

Parameter

Comments

agent_ip

string

Specifies the IPv4/IPv6 address of an sFlow agent.

collector_datagram_size

string

Specifies the maximum length of sFlow packets sent from an sFlow agent to an sFlow collector. The value is an integer, in bytes. It ranges from 1024 to 8100. The default value is 1400.

collector_description

string

Specifies the description of an sFlow collector. The value is a string of 1 to 255 case-sensitive characters without spaces.

collector_id

string

Specifies the ID of an sFlow collector. This ID is used when you specify the collector in subsequent sFlow configuration.

Choices:

  • "1"

  • "2"

collector_ip

string

Specifies the IPv4/IPv6 address of the sFlow collector.

collector_ip_vpn

string

Specifies the name of a VPN instance. The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. The value _public_ is reserved and cannot be used as the VPN instance name.

collector_meth

string

Configures the device to send sFlow packets through service interfaces, enhancing the sFlow packet forwarding capability. The enhanced parameter is optional. No matter whether you configure the enhanced mode, the switch determines to send sFlow packets through service cards or management port based on the routing information on the collector. When the value is meth, the device forwards sFlow packets at the control plane. When the value is enhanced, the device forwards sFlow packets at the forwarding plane to enhance the sFlow packet forwarding capacity.

Choices:

  • "meth"

  • "enhanced"

collector_udp_port

string

Specifies the UDP destination port number of sFlow packets. The value is an integer that ranges from 1 to 65535. The default value is 6343.

counter_collector

string

Indicates the ID list of the counter collector.

counter_interval

string

Indicates the counter sampling interval. The value is an integer that ranges from 10 to 4294967295, in seconds. The default value is 20.

export_route

string

Configures the sFlow packets sent by the switch not to carry routing information.

Choices:

  • "enable"

  • "disable"

sample_collector

string

Indicates the ID list of the collector.

sample_direction

string

Enables flow sampling in the inbound or outbound direction.

Choices:

  • "inbound"

  • "outbound"

  • "both"

sample_length

string

Specifies the maximum length of sampled packets. The value is an integer and ranges from 18 to 512, in bytes. The default value is 128.

sample_rate

string

Specifies the flow sampling rate in the format 1/rate. The value is an integer and ranges from 1 to 4294967295. The default value is 8192.

sflow_interface

string

Full name of interface for Flow Sampling or Counter. It must be a physical interface, Eth-Trunk, or Layer 2 subinterface.

source_ip

string

Specifies the source IPv4/IPv6 address of sFlow packets.

state

string

Determines whether the config should be present or not on the device.

Choices:

  • "present" ← (default)

  • "absent"

Notes

Note

  • This module requires the netconf system service be enabled on the remote device being managed.

  • Recommended connection is netconf.

  • This module also works with local connections for legacy playbooks.
