community.network.flowadm module – Manage bandwidth resource control and priority for protocols, services and zones on Solaris/illumos systems

Note

This module is part of the community.network collection (version 3.3.0).

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.flowadm.

Synopsis

• Create/modify/remove networking bandwidth and associated resources for a type of traffic on a particular link.

Parameters

Parameter	Comments
dsfield string	Identifies the 8-bit differentiated services field (as defined in RFC 2474). The optional dsfield_mask is used to state the bits of interest in the differentiated services field when comparing with the dsfield value. Both values must be in hexadecimal.
link string	Specifiies a link to configure flow on.
local_ip string	Identifies a network flow by the local IP address.
local_port string	Identifies a service specified by the local port.
maxbw string	Sets the full duplex bandwidth for the flow. The bandwidth is specified as an integer with one of the scale suffixes(K, M, or G for Kbps, Mbps, and Gbps). If no units are specified, the input value will be read as Mbps.
name aliases: flow string / required	A flow is defined as a set of attributes based on Layer 3 and Layer 4 headers, which can be used to identify a protocol, service, or a zone.
priority string	Sets the relative priority for the flow. Choices: low medium ← (default) high
remote_ip string	Identifies a network flow by the remote IP address.
state string	Create/delete/enable/disable an IP address on the network interface. Choices: absent present ← (default) resetted
temporary boolean	Specifies that the configured flow is temporary. Temporary flows do not persist across reboots. Choices: no ← (default) yes
transport string	Specifies a Layer 4 protocol to be used. It is typically used in combination with local_port to identify the service that needs special attention.

Examples

- name: Limit SSH traffic to 100M via vnic0 interface
  community.network.flowadm:
    link: vnic0
    flow: ssh_out
    transport: tcp
    local_port: 22
    maxbw: 100M
    state: present

- name: Reset flow properties
  community.network.flowadm:
    name: dns
    state: resetted

- name: Configure policy for EF PHB (DSCP value of 101110 from RFC 2598) with a bandwidth of 500 Mbps and a high priority
  community.network.flowadm:
    link: bge0
    dsfield: '0x2e:0xfc'
    maxbw: 500M
    priority: high
    flow: efphb-flow
    state: present

local_port integer	flow’s local port Returned: if local_port is defined Sample: 1337
maxbw string	flow’s maximum bandwidth Returned: if maxbw is defined Sample: “100M”
name string	flow name Returned: always Sample: “http_drop”
priority string	flow’s priority Returned: if priority is defined Sample: “low”
remote_Ip string	flow’s remote IP address Returned: if remote_ip is defined Sample: “10.0.0.42”
state string	state of the target Returned: always Sample: “present”
temporary boolean	flow’s persistence Returned: always Sample: “True”
transport string	flow’s transport Returned: if transport is defined Sample: “tcp”
