short_description: Manage the system attributes on Cisco IOS XR devices
|
|
description:
|
|
- This module provides declarative management of node system attributes
|
|
on Cisco IOS XR devices. It provides an option to configure host system
|
|
parameters or remove those parameters from the device active
|
|
configuration.
|
|
extends_documentation_fragment: iosxr
|
|
notes:
|
|
- Tested against IOS XR 6.1.2
|
|
options:
|
|
hostname:
|
|
description:
|
|
- Configure the device hostname parameter. This option takes an ASCII string value.
|
|
domain_name:
|
|
description:
|
|
- Configure the IP domain name
|
|
on the remote device to the provided value. Value
|
|
should be in the dotted name form and will be
|
|
appended to the C(hostname) to create a fully-qualified
|
|
domain name.
|
|
domain_search:
|
|
description:
|
|
- Provides the list of domain suffixes to
|
|
append to the hostname for the purpose of doing name resolution.
|
|
This argument accepts a list of names and will be reconciled
|
|
with the current active configuration on the running node.
|
|
lookup_source:
|
|
description:
|
|
- The C(lookup_source) argument provides one or more source
|
|
interfaces to use for performing DNS lookups. The interface
|
|
provided in C(lookup_source) must be a valid interface configured
|
|
on the device.
|
|
lookup_enabled:
|
|
description:
|
|
- Provides administrative control
|
|
for enabling or disabling DNS lookups. When this argument is
|
|
set to True, lookups are performed and when it is set to False,
|
|
lookups are not performed.
|
|
type: bool
|
|
name_servers:
|
|
description:
|
|
- The C(name_serves) argument accepts a list of DNS name servers by
|
|
way of either FQDN or IP address to use to perform name resolution
|
|
lookups. This argument accepts wither a list of DNS servers See
|
|
examples.
|
|
state:
|
|
description:
|
|
- State of the configuration
|
|
values in the device's current active configuration. When set
|
|
to I(present), the values should be configured in the device active
|
|
configuration and when set to I(absent) the values should not be
