- Manages Eth-Trunk specific configuration parameters on HUAWEI CloudEngine switches.
|
|
author: QijunPan (@CloudEngine-Ansible)
|
|
notes:
|
|
- C(state=absent) removes the Eth-Trunk config and interface if it
|
|
already exists. If members to be removed are not explicitly
|
|
passed, all existing members (if any), are removed,
|
|
and Eth-Trunk removed.
|
|
- Members must be a list.
|
|
options:
|
|
trunk_id:
|
|
description:
|
|
- Eth-Trunk interface number.
|
|
The value is an integer.
|
|
The value range depends on the assign forward eth-trunk mode command.
|
|
When 256 is specified, the value ranges from 0 to 255.
|
|
When 512 is specified, the value ranges from 0 to 511.
|
|
When 1024 is specified, the value ranges from 0 to 1023.

min_links:
|
|
description:
|
|
- Specifies the minimum number of Eth-Trunk member links in the Up state.
|
|
The value is an integer ranging from 1 to the maximum number of interfaces
|
|
that can be added to a Eth-Trunk interface.
