はじめに
以前、restconf_get モジュールで Cisco IOS XE のインターフェース情報を取得してみる という記事で、Ansible で RESTCONF 経由で情報取得する Playbook をご紹介しました。
この記事では RESTCONF ではく、netconf_get モジュールでCisco IOS XE の情報を取得する Playbook をご紹介します。
サンプルは、 running-config、インターフェース状態、ルーティングテープルの取得です。
- 環境
- ■ 準備
- ■ Playbookサンプル1: running-config を取得
- ■ Playbookサンプル2: インターフェースの状態を取得
- ■ サンプル3: ルーティングテーブルの取得
- ■ おわりに
環境
- Cisco IOS-XE (16.11)
- Ansible 2.9.9
■ 準備
Playook 実行に必要なファイルを作成しますす。
インベントリファイル
ホスト情報を示すインベントリファイルを作成します。
inventory.ini
[ios] ios1 ansible_host=ios-xe-mgmt.cisco.com
変数定義ファイル
インベントリファイルで定義したグループ ios が利用する変数を定義するファイルを作成します。
group_vars/ios.yml
# ansible_network_os: ios # 不要 ansible_connection: netconf ansible_port: 10000 ansible_user: developer ansible_password: dummy
| 変数名 | 説明 |
|---|---|
ansible_connection |
一番のポイントです。netconf コネクションプラグインを利用するために netconf を指定します。 |
ansible_port |
NETCONF 接続に利用するポートです。netconf コネクションプラグインの場合のデフォルトは 830 です。ここでは環境の都合で 10000 を指定します。 |
ansible_user |
ユーザー名を指定します。 |
ansible_password |
ここではダミーの値を記載しています。必要に応じて ansible-vault で暗号化します。 |
■ Playbookサンプル1: running-config を取得
source オプションで running を指定すると、running-config を NETCONF / YANG 形式で取得できます。

■ Playbookサンプル2: インターフェースの状態を取得
filter オプションで、XMLで階層を指定すると取得する情報を絞れます。
インターフェースの情報は以下のようなフィルターをかけます。（参考: ietf-interfaces.yang）
<interfaces-state xmlns="urn:ietf:params:xml:ns:yang:ietf-interfaces"> </interfaces-state>
コマンドでいうと、show interfaces あたりでしょうか。

netconf_get モジュールでは、display オプションで json を指定することで、表示を JSON にすることができます。前に pip install jxmlease しておく必要があります。

■ サンプル3: ルーティングテーブルの取得
ルーティングテーブルを取得したい場合は、以下のようなフィルターをかけます、（参考: ietf-routing.yang）
<routing-state xmlns="urn:ietf:params:xml:ns:yang:ietf-routing"> </routing-state>
先程指定した display: json をここでも指定します。

■ おわりに
RESTCONF 同様、NETCONF は 構造化データを扱えるため、assert モジュールによる状態確認や、レポートに応用しやすいと思いました。
