module: ce_info_center_trap
short_description: Manages information center trap configuration on HUAWEI CloudEngine switches.
description:
- Manages information center trap configurations on HUAWEI CloudEngine switches.
author:
- wangdezhuang (@QijunPan)
notes:
- This module requires the netconf system service be enabled on the remote device being managed.
- Recommended connection is C(netconf).
- This module also works with C(local) connections for legacy playbooks.
options:
state:
description:
- Specify desired state of the resource.
default: present
choices: ['present','absent']
trap_time_stamp:
description:
- Timestamp format of alarm information.
choices: ['date_boot', 'date_second', 'date_tenthsecond', 'date_millisecond', 'shortdate_second',
'shortdate_tenthsecond', 'shortdate_millisecond', 'formatdate_second', 'formatdate_tenthsecond',
'formatdate_millisecond']
trap_buff_enable:
description:
- Whether a trap buffer is enabled to output information.
default: no_use
choices: ['no_use','true','false']
trap_buff_size:
description:
- Size of a trap buffer.
The value is an integer ranging from 0 to 1024. The default value is 256.
module_name:
description:
- Module name of the rule.
The value is a string of 1 to 31 case-insensitive characters. The default value is default.
Please use lower-case letter, such as [aaa, acl, arp, bfd].
channel_id:
description:
- Number of a channel.
The value is an integer ranging from 0 to 9. The default value is 0.
trap_enable:
description:
- Whether a device is enabled to output alarms.
default: no_use
choices: ['no_use','true','false']
trap_level:
description:
- Trap level permitted to output.
choices: ['emergencies', 'alert', 'critical', 'error', 'warning', 'notification',
'informational', 'debugging']
