module: slxos_l3_interface
author: "Matthew Stone (@bigmstone)"
short_description: Manage L3 interfaces on Extreme Networks SLX-OS network devices.
description:
- This module provides declarative management of L3 interfaces
on slxos network devices.
notes:
- Tested against slxos 15.2
options:
name:
description:
- Name of the L3 interface to be configured eg. Ethernet 0/2
ipv4:
description:
- IPv4 address to be set for the L3 interface mentioned in I(name) option.
The address format is <ipv4 address>/<mask>, the mask is number
in range 0-32 eg. 192.168.0.1/24
ipv6:
description:
- IPv6 address to be set for the L3 interface mentioned in I(name) option.
The address format is <ipv6 address>/<mask>, the mask is number
in range 0-128 eg. fd5d:12c9:2201:1::1/64
aggregate:
description:
- List of L3 interfaces definitions. Each of the entry in aggregate list should
define name of interface C(name) and a optional C(ipv4) or C(ipv6) address.
state:
description:
- State of the L3 interface configuration. It indicates if the configuration should
be present or absent on remote device.
default: present
choices: ['present', 'absent']
