Juniper vSRX(15.1X) を VirtualBox で動かす (original : 2015/12/11)
この記事は某所で 2015/12/11 に書いたもののコピーです。
そのため 2017/05/13 時点ではやや古い情報も含まれています。
- Juniper さんの vSRX ダウンロード規約が変わっていそう (詳細は未確認)
.
概要
本項でやること
- KVM、VMware ESX 向けの 60 日間 trial 版が公開されている Juniper vSRX を VirtualBox に入れる
- 公式にはサポートされない手順なので、自己責任で
- JUNOS の基本的な操作は省略(ある程度知っている人向け)
環境情報
- ホスト： Windows7 + VirtualBox 4.3.18
- Juniper vSRX: JUNOS 15.1X49-D15.4
vSRX?
- Juniper SRX の 仮想版
- 以前は Firefly Perimeter として公開されていた
- DPDK 対応などの機能強化を果たして、ほぼ別物として名前も Firefly から vSRX になった
- 参考 2014年03月時点での Firefly Perimeter ロードマップなど
- version が 12.1X となっているものは Firefly で 15.1X となっているものは vSRX
- だが、最近は旧 Firefly も vSRX と呼ばれていたりして、ややこしい
手順
vSRX イメージファイル取得
- Trial 版ダウンロードページ | Juniper または ダウンロードページ | Juniper にアクセス
vSRX VMware Appliance with IDE virtual diskを選択してmedia-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide.ovaをダウンロード2015/11/23現在の最新版
ovf 形式にファイル変換
- 取得したovaファイルを ovf 形式にする (以下例では VMwarePlayer などに同梱されている ovftool を使用)
>ovftool.exe media-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide.ova \convert\media-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide.ovf Opening OVA source: media-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide.ova The manifest validates Opening OVF target: \convert\media-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide.ovf Writing OVF package: \convert\media-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide.ovf Transfer Completed Source is signed but could not verify certificate (possibly self-signed) Completed successfully
media-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide.ovf media-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide-disk1.vmdk media-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide.mf
変換したファイルに小細工(インポートエラーが出ないように)
media-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide.mfファイルは別ディレクトリに除外しておくmedia-srx-ffp-vsrx-vmdisk-15.1X49-D15.4.ide.ovfの line 82 を以下のように上書き編集(%iid%->2)
編集前
<Item ovf:configuration="4GvRAM">
<rasd:AllocationUnits>byte * 2^20</rasd:AllocationUnits>
<rasd:Description>Memory Size</rasd:Description>
<rasd:ElementName>Memory</rasd:ElementName>
<rasd:InstanceID>%iid%</rasd:InstanceID>
<rasd:ResourceType>4</rasd:ResourceType>
<rasd:VirtualQuantity>4096</rasd:VirtualQuantity>
編集後
<Item ovf:configuration="4GvRAM">
<rasd:AllocationUnits>byte * 2^20</rasd:AllocationUnits>
<rasd:Description>Memory Size</rasd:Description>
<rasd:ElementName>Memory</rasd:ElementName>
<rasd:InstanceID>2</rasd:InstanceID>
<rasd:ResourceType>4</rasd:ResourceType>
<rasd:VirtualQuantity>4096</rasd:VirtualQuantity>
VirtualBox に ovf をインポート
ファイル->仮想マシンのインポートで先の編集した ovf ファイルを指定
- 以降の画面キャプチャはインポート後の設定からとってきたもの
- どうやら
アダプタータイプは一回起動したあとは勝手に準仮想化ネットワーク(virtio-net)にされるようだ アダプター 1が JUNOS 側から見るとfxp0(管理用ポート)になる
コンソール画面から初期設定
- 起動する
- 無事に起動できたら、コンソールログインして以下を設定する
# root password の設定(必須) set system root-authentication plain-text-password -> 対話型で入力 # ユーザ作成とパスワード設定 set system login user <username> class super-user set system login user <username> authentication plain-text-password # ssh 有効化 set system services ssh root-login deny set system services ssh protocol-version v2
- 必要に応じて、以下手順でデフォルトのファイアウォールモードからルータモード(いずれも俗称)に切り替える(要再起動)
ssh して状態確認

bagpipe-bgp インストール～簡易動作確認 (original : 2015/11/08)
この記事は某所で 2015/11/08 に書いたもののコピーです。
そのため 2017/05/13 時点ではやや古い情報も含まれています。
概要
本項でやること
- bagpipe-bgp をインストールして軽く動作確認するところまでです
- 一般的に OpenStack Neutron と組み合わせて使うようですが、ここでは OpenStack は登場しません
- OSS で手軽に EVPN を試せそう、というのがモチベーションです
環境情報
$ uname -a Linux as65000-l1 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=14.04 DISTRIB_CODENAME=trusty DISTRIB_DESCRIPTION="Ubuntu 14.04.3 LTS"
手順

bagpipe-bgp service 登録(～自動起動設定)
$ cd bagpipe-bgp/ $ ./install_bagpipe_bgp.sh *** WARNING: This script must be run as root *** $ sudo ./install_bagpipe_bgp.sh $ sudo service bagpipe-bgp status BGP component is running.
- 自動起動したい場合は、サンプルが同梱されているので、これを配置すればよかろう(ここでは未実施)
$ ls -al bagpipe-bgp/etc/init.d/ total 16 drwxrwxr-x 2 kotetsu kotetsu 4096 Nov 8 01:25 . drwxrwxr-x 3 kotetsu kotetsu 4096 Nov 8 01:25 .. -rwxrwxr-x 1 kotetsu kotetsu 2518 Nov 8 01:25 bagpipe-bgp -rwxrwxr-x 1 kotetsu kotetsu 1545 Nov 8 01:25 bagpipe-fakerr
bagpipe-bgp 設定ファイルの編集
メイン設定ファイル (/etc/bagpipe-bgp/bgp.conf)
/etc/bagpipe-bgp/bgp.conf- ネットワーク環境に合わせて
[BGP]の項目を編集- iBGP しか使えないことに注意
$ ls -al /etc/bagpipe-bgp/ total 24 drwxr-xr-x 2 root root 4096 Nov 8 01:57 . drwxr-xr-x 83 root root 4096 Nov 8 01:57 .. -rw-r--r-- 1 root root 3099 Nov 8 01:57 bgp.conf -rw-rw-r-- 1 root root 3099 Nov 8 01:25 bgp.conf.template -rw-r--r-- 1 root root 1615 Nov 8 01:57 log.conf -rw-rw-r-- 1 root root 1615 Nov 8 01:25 log.conf.template $ cat /etc/bagpipe-bgp/bgp.conf [BGP] local_address=10.0.1.2 peers=10.0.1.1 my_as=65000 enable_rtc=False (略) $ diff /etc/bagpipe-bgp/bgp.conf /etc/bagpipe-bgp/bgp.conf.template 2,5c2,5 < local_address=10.0.1.2 < peers=10.0.1.1 < my_as=65000 < enable_rtc=False --- > local_address=192.168.100.177 > peers=192.168.0.101 > my_as=64512 > enable_rtc=True
log 出力設定ファイル (/etc/bagpipe-bgp/log.conf)
/etc/bagpipe-bgp/log.conf[logger_engine]だけ出力レベルを WARNING からDEBUGに変更(様子を観察するため)- デフォルトでは
/var/log/bagpipe-bgp/bagpipe-bgp.logに出力される
$ cat /etc/bagpipe-bgp/log.conf (略) [logger_engine] level=DEBUG propagate=0 qualname=bagpipe.bgp.engine handlers=rotatingFile parent=bgp (略) $ diff /etc/bagpipe-bgp/log.conf /etc/bagpipe-bgp/log.conf.template 25c25 < level=DEBUG --- > level=WARNING
bagpipe-bgp 起動～状態確認
ここからの例では起動の前に、適当な iBGP neighbor を用意しておきます。
起動
serviceで普通に扱うだけ- 要 root 権限
$ sudo service bagpipe-bgp start Starting BGP component... $ sudo service bagpipe-bgp restart Restarting BGP component... stopping.........starting $ sudo service bagpipe-bgp status BGP component is running.
ログ確認
- デフォルトのログ設定ではさほど出力されないが、前述の通り
[logger_engine]の level を DEBUG に変えたので、やたら出ている

おまけ CLI's tab 補完(bash 用) 導入
- 'gobgp' 各種コマンドを Tab 補完できるようになるので、入れておくと便利
$ cd ~/gobgp $ wget https://raw.githubusercontent.com/osrg/gobgp/master/tools/completion/gobgp-completion.bash $ ls -al total 56 drwxrwxr-x 2 kotetsu kotetsu 4096 Nov 7 23:32 . drwxr-xr-x 6 kotetsu kotetsu 4096 Nov 7 22:07 .. -rw-rw-r-- 1 kotetsu kotetsu 41832 Nov 7 23:32 gobgp-completion.bash -rw-rw-r-- 1 kotetsu kotetsu 354 Nov 7 22:10 gobgpd.conf $ source ~/gobgp/gobgp-completion.bash
おわり
- インストールしただけなので別に…
Arista EOS の python コード読み始め (original : 2015/05/06)
この記事は某所で 2015/05/06 に書いたもののコピーです。
そのため 2017/05/13 時点ではやや古い情報も含まれています。
概要
本項でやること
EOS の読んでおきたいコードをメインに、ディレクトリ構造を追いました。本項単体では何も得られない僕向けの内容です。マニュアルで得られない情報をコードやコメントから読み取るのって、楽しいんですよね(死んだ魚の目)。
以下のようなことをやるための前戯の意味もあります。
- 自分だけの CLI コマンドを実装( Understanding EOS CLI implementation 参照)
- EOS を介さずに sysdb を直接突く (後述)
- RPM をインストールして EOS の extension として動かして機能拡張( Packaging and installing EOS extensions 参照)
sysdb に関しては、直接突くための SDK が公式で公開されているのですが、EOS 側にインストール必要な rpm が Guest アカウントでは Download 権限がなかったです(2015/05/03 時点)。
そこで EOS の python コードを読めば(その中で sysdb を呼び出している筈なので)、SDK がなくても突けるのではないかと考えました(未施行)。
Arista EOS?
Arista EOS 自体については、以下の本をオススメしときますね。

環境
2015/04 にリリースされたばかりの 4.15.0F が、vEOS にも早速来ていました。ウヒョー！
- Aboot-veos：Aboot-veos-2.1.0
- OS：vEOS-4.15.0F
- CPU：1core
- Memory：1024MB
サマリ
| path | 内容 |
|---|---|
| /mnt/flash | OS ファイルや startup-config ファイルが配置されているディレクトリ |
| /mnt/flash/.extensions | extension として読み込ませる rpm を配置するディレクトリ |
| /usr/bin/[A-Z]* | Arista 固有 agent 群 |
| /usr/lib/python2.7/site-packages/*.py | EOS コア系処理 |
| /usr/lib/python2.7/site-packages/SysdbPlugin/*.py | Sysdb 構成 |
| /usr/lib/python2.7/site-packages/CliPlugin/*.py | EOS CLI コマンドの定義をしている python スクリプト群 |
| /usr/lib/python2.7/site-packages/MlagPlugin/*.py | MLAG 関係の sysdb 読み書きをしている python スクリプト群 |
なので /usr/lib/python2.7/site-packages/ 配下を固めて手元に持ってきて、適当なエディタにぶち込んで読んでます。
詳細
EOS CLI から bash に降りる
こんな感じで。

Python が入っていない NW 機器も Ansible で (一応) 制御できる (original : 2015/02/15)
この記事は某所で 2015/02/15 に書いたもののコピーです。
そのため 2017/05/13 時点ではやや古い情報も含まれています。(以下一例)
Ansibleのバージョンが当時の1.8から2.3くらいまであがっているので、挙動が異なる部分がある筈
.
概要
本項でやること
target に python が入っていなくても ssh 接続可能ならば Ansible で一応制御できる、ということを軽く確認します。 Linux ベースではないネットワーク機器(Cisco IOS etc)などで使える筈です。
気をつけること(≒結論)
ansible：1.8.2 では、以下を満たせばいける筈です。
gather_factsはnoにすること- コマンド実行 module は
rawを使うこと (shellやcommandではない) sshのcommandで target にリモートコマンド実行できること
参考情報(公式より)
何でコマンド実行 module として raw を使うのか
Ansible の config ファイルで使える ssh 系のオプション設定
環境情報
Ansible
target device (NW機器)
Python が入っていない NW 機器代表として Juniper Firefly を使いました。 FreeBSD ベースではありますが。

ansible.cfg
ssh 接続に Paramiko と OpenSSH のいずれを使うか、という話がありますが…今回はオプションが豊富な OpenSSH を使っています。
[defaults] transport=ssh [ssh_connection] ssh_args= -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o ControlMaster=no -o ControlPersist=60s scp_if_ssh=false
Playbook
単純に ssh の command で show version | no-more を実行して、結果を debug で表示させるだけです。

雑記
VyOS と Arista で VXLAN 相互接続 (original : 2014/12/24)
この記事は某所で 2014/12/24 に書いた記事のコピーです。
そのため 2017/05/11 時点ではやや古い情報も含まれています。
概要
また Arista ですか？ いえ、これは VyOS Advent Calendar 2014 の記事です。
本項でやること
VyOS と Arista で VXLAN 相互接続します。
とはいえ、interoperability で色々痛い目にあってきた人が思うような苦難は全く無いです。
Arista と VyOS では VXLAN で使おうとする dstPort 番号が異なるのですが、VyOS の記事なので敢えて VyOS 側でこれを変えます。
# デファクトスタンダードな openvswitch ではなく、何でニッチなアレ同士で…というツッコミは不可。
前段
VXLAN とは?
VXLAN 相互接続で気にすべき点
事前の鍵交換 phase やらの面倒ごとが無いシンプルなプロトコルなので、2 台で相互接続する分には左程気をつける点は無いです。
今年の Shownet では、各メーカの箱モノで相互接続実験とかやっていて、(以下のスライド 68-75)
これを見ても気にする点は以下くらいだと分かります。
- BUM トラフィック転送方法 (Unicast or Multicast)
- UDP dstport 番号 (4789 or 8472)
- VXLAN カプセリング時の 802.1q tag 取扱い (除去 or そのまま)
1 つ目は製品によってマチマチです。RFC では Multicast 実装が示されています。
2 つ目は、本項でも気にしています。draft で「IANA から UDP ポート番号割り当ててもらわないと～」と言っている時代が長かったからなのか、Linux VXLAN では 8472 が今も使われています。その内どうにかしないと、ってスタンスではあるようです。( Linux/drivers/net/vxlan.c 参照)
現在は IANA から 4789 を割り当てられているので、最近はそれを使っている・過去の経緯を考慮して dstport 変更可能な製品が多いです。
3 つ目は RFC で取り除けと言ってます↓。本項では、access VLAN しか使っていないので、見ていません。
a VTEP SHOULD NOT include an inner VLAN tag on tunnel packets
本項で取り扱う VTEP 実装
VyOS
VyOS なので基本的に Linux ベースです。
VyOS に VXLAN 取り込んだよ、って話は作者の以下資料を参照して下さい。
VXLAN の dstport に関して(の悩みどころ)はスライド 23 に書かれています。
VyOS 1.1.1 現在は普通に動かすと、dstport 8472 で動きます。
Arista
VXLAN が動かない機器群を収容して、自分が VTEP をやる Hardware VTEP です。(本項で使うのは Software 版ですが…)
デフォルトの dstport は 4789 ですが、設定で変更して既存の 8472 に歩み寄ることができます。本項ではやりませんが。
とりあえず、メーカが出している分かり易い資料は以下です。
Arista EOS 自体については、以下の本をオススメしときますね。

環境情報など
構成図/環境
以下の構成でやります。全て箱庭の仮想環境です。
赤いテナントと青いテナントを Isolation します、的な。
ルータは multicast routing 出来れば、何でも良いです(VyOS 1.1.1 では不可だけど実装予定には入っているみたい)。 ノードは何でも良いです。
ホスト環境
- ホスト：Windows7 + VirtualBox 4.3.18
VyOS 環境 (VTEP)
- OS：VyOS 1.1.1
- CPU：1Core
- Memory：256MB
Arista 環境 (VTEP)
- Aboot-veos：Aboot-veos-2.1.0
- OS：vEOS-4.14.2F
- CPU：1core
- Memory：1024MB
Firefly 環境 (ルータ)
- OS：12.1X47-D10.4
- CPU：2core
- Memory：2048MB
ノード環境 (4台共)
事前準備
VyOS のデプロイ
以下を参考に作っておきます。2014/12/24 現在の最新版である 1.1.1 を使います。
Arista(vEOS) のデプロイ
以下リンクを参考に作っておきます。公式に、各種ハイパーバイザごとの導入手順詳細とかもあります。
Firefly のデプロイ～ルータモードに変更
以下リンクを参考に作っておきます。(これは VMPlayer 版ですが、各種ハイパーバイザ使えます。)
あと、デフォルトだと firewall 的な動作をして鬱陶しいので、以下を参考にルータモード(俗称)に切り替えておきます。
Ubuntu のデプロイと設定
ノードの OS は別に問わないので、好きに作って IP アドレス設定だけすれば OK です。 VLAN tag とかも食いません。
設定
VyOS の VXLAN 設定
modprobe vxlan に udp_port オプション追記
事前に Linux Kernel と VyOS バージョン確認しておきます。

VXLAN の Kernel module を modprobe する時点で dstport をデフォルトの 8472 から 4789 に変更されるように、以下ファイルを書き換えます。
kotetsu@vyos# ls -alh /opt/vyatta/share/vyatta-cfg/templates/interfaces/vxlan total 20K drwxr-xr-x 3 root root 4.0K Dec 23 00:53 . drwxr-xr-x 16 root root 4.0K Dec 8 06:44 .. -rw-r--r-- 1 root root 1.1K Dec 23 00:53 node.def -rw-r--r-- 1 root root 1.1K Oct 30 17:43 node.def.orig drwxr-xr-x 13 root root 4.0K Dec 8 06:44 node.tag kotetsu@vyos:~$ sudo diff /opt/vyatta/share/vyatta-cfg/templates/interfaces/vxlan/node.def /opt/vyatta/share/vyatta-cfg/templates/interfaces/vxlan/node.def.orig 14c14 < [ -d /sys/module/vxlan ] || sudo modprobe vxlan udp_port=4789 --- > [ -d /sys/module/vxlan ] || sudo modprobe vxlan
CLI で設定
では構成図のように順次設定していきます。

VyOS が認識しないといけない Arista 側の VTEP IP アドレスは、Arista の Loopback アドレスになるので、StaticRoute を追加しておきます。 #これだと拡張が面倒なので、実環境では DefaultRoute か動的ルーティングを使うことが多い気がします。
set protocols static route 172.16.3.1/32 next-hop '172.16.2.254'
commit ～ save して設定確認しておきます。

以下のように VXLAN インターフェースの source-interface には、Loopback Interface しか適用できません。VyOS などの dev と同じノリで物理IFを指定できるかと思いきや…。

このままだと VTEP は 239.0.0.1 宛の通信をどこに投げればいいのか分からないので、Multicast Routing の設定をします。

雑感
Arista の REST(っぽい) API を ruby や Ansible で突いてみよう (original : 2014/12/14)
この記事は某所で 2014/12/14 に書いたもののコピーです。
そのため 2017/05/13 時点ではやや古い情報も含まれています。(以下一例)
Ansibleのバージョン1.8系、今となっては古い- 今は
Arista公式がRuby用のライブラリを公開している(当時はなかった) - 本記事でとりあげた
Arista公式のAnsibleモジュールは、今は「Ansible の Core Module に入っている方を使ってね」と言っている
.
概要
もう expect して正規表現でシコシコしないで良いんですか！？やった～！！
本項でやること
Arista の REST API である eAPI を触ります。
http or https で REST 叩けてリクエストやレスポンスの JSON を弄れれば、クライアント実装は何でも良いですが以下を試します。
- arista-eapi (ruby の gem)
- arista.eos (Arista 公式が出している Ansible モジュール)
いずれも「Arista EOS の REST API(eAPI) を操作することに特化」しており、これを使うと Arista の操作が楽々だ～というのを見ます。
両方で「現在の設定情報を取得して、それを基に設定投入」という操作を試します。
vEOS や ruby や ansible 本体のセットアップについては、記載しません。
Arista EOS?
この本をオススメしときますね。

eAPI とは?
公式 "Introduction to Managing EOS Devices – Setting up Management" の記載から抜粋します。
Arista EOS provides multiple APIs, of which Extensible API (eAPI) is a RESTFUL programmatic interface based on the JSON structured format via HTTP or HTTPS, to simplify interactions with any Arista EOS.
情報取得や設定投入が出来ます。
リクエスト内に CLI コマンドをそのまま埋め込んで投げると、JSON で構造化されたレスポンスを得られます。
環境情報など
構成図・環境
以下の構成でやります。
Arista(vEOS) 含め全て仮想 OS です。
物理?構成は一般的なデータセンタネットワークのそれで、Arista の Multi-Chassis Link Aggregation (MLAG)を使っています。
本項では MLAG の詳細は説明しません & 設定内容もベストプラクティスではないです。
ruby 環境は nwman というノードで、Ansible 環境は ansible というノードで動かしますが、分けているのは単に元々あった環境の都合です。
ホスト環境
- ホスト：Windows7 + VirtualBox 4.3.18
ruby 環境
- OS：CentOS release 6.5
- ruby：ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux]
- gem：arista-eapi (0.11.1)
- gem：json (1.8.1)
- gem：rest-client (1.7.2)
Ansible 環境
Arista 環境
- vEOS Aboot-veos：Aboot-veos-2.1.0
- vEOS OS：vEOS-4.14.2F
- vEOS CPU：1core
- vEOS Memory：1024MB
eAPI 操作内容、利用 API
今回は上記構成にて「VLAN 30 と同じトポロジで VLAN 31 を作る」という操作をします。つまり
- 対象機の VLAN 状態を取得して「VLAN 30 が存在するか」・「存在する場合、VLAN 30 をどこの物理 IF に trunk で通しているか」を判断
- 1 で VLAN 30 が存在する場合、VLAN 31 を作る
- 1 で VLAN 30 が存在する場合、VLAN 30 を通している全物理 IF に VLAN 31 を追加で通す
- 2-3 を実施した場合、メモリに設定保存
てな流れです。
同じことを ruby と Ansible 両方で試します。
1 では "show vlan" をリクエストに埋め込んで状態取得します。
レスポンスの例は以下の感じです。(後述の "Exploler" で実行したコピペ)
{ "jsonrpc": "2.0", "result": [ { "sourceDetail": "", "_meta": { "execDuration": 0.04, "execStartTime": 1417437611.14 }, "vlans": { "1": { "status": "active", "name": "default", "interfaces": { "Ethernet2": { "annotation": "port channel configuration", "privatePromoted": false }, "Port-Channel1": { "privatePromoted": false }, "Ethernet1": { "annotation": "port channel configuration", "privatePromoted": false } }, "dynamic": false } } } ], "id": "CapiExplorer-123" }
事前準備
vEOS x4 (spine001/002, leaf001/002)のデプロイ
以下リンクを参考に作っておきます。公式に、各種ハイパーバイザごとの導入手順詳細とかもあります。
vEOS x4 で eAPI 有効化
有効化設定
公式 "Introduction to Managing EOS Devices – Setting up Management" の "1.10 eAPI" 通りで。
本項ではプロトコルに HTTP を使います。(HTTPS で vEOS 自己証明書の対応するのが面倒ってだけの理由です。)
デフォルトは HTTPS で、以下は HTTP で動かす例です。
leaf001#conf t leaf001(config)#management api http-commands leaf001(config-mgmt-api-http-cmds)#no protocol https leaf001(config-mgmt-api-http-cmds)#protocol http leaf001(config-mgmt-api-http-cmds)#no shutdown
http が動いていることを確認します。
leaf002#show management api http-commands Enabled: Yes HTTPS server: shutdown, set to use port 443 HTTP server: running, set to use port 80 VRF: default Hits: 0 Last hit: never Bytes in: 0 Bytes out: 0 Requests: 0 Commands: 0 Duration: 0.000 seconds URLs -------------------------------------- Management1 : http://192.168.101.53:80
ブラウザで eAPI 簡易動作確認
vEOS の Management に疎通可能な端末のブラウザで http[s]://<ip_address_switch>/ にアクセスします。
認証は vEOS に作ってあるアカウント/パスワードで。
"Command Documentation" では参照(show)系 API の仕様が見られます。設定系はなかったです。
"Explorer" ではリクエストのパラメータを少し入力するだけで簡易に試せます。(ブラウザの RestClient アドオン的な)
"Overview" ではエラーコードの説明などが見られます。スタートアップガイド的な。
2014/12/14 現在、eAPI ドキュメントは Web 上やマニュアルとしては整備されていなくて、ここで見られる情報が一番豊富だと思います。
しかし公式の QA (Supported Commands for eAPI? ) を見ると、今後マニュアルが整備されるのかも知れません。
vEOS セットアップ(その他)～実行前 config
詳細は省略しますが、VLAN や物理IF などの設定を構成図のようにセットアップしました。
ruby 版も Ansible 版も、これが実行前 config になります。

ruby (arista-eapi gem) 版
どんな gem?
Arista 公式が出しているものではないです。
特徴は以下の感じです。
- REST 周りの処理、リクエスト生成、JSON レスポンスのパースをしてくれる (ので、ユーザがやりたいことだけコーディングできる)
- リクエストのコマンド群やレスポンスは Array で表現される
- レスポンスの JSON は symbolize された Hash で取得できる
- 任意のコマンドを実行できる run メソッドと、コマンドを書かずに簡易に情報取得可能なメソッド(2014/12 現在は version だけ)がある
run メソッドさえあれば困ることはないので、本項ではそれでやります。
インストール
普通に gem install で入れました。
# gem install arista-eapi # gem list *** LOCAL GEMS *** arista-eapi (0.11.1) json (1.8.1, 1.7.7) mime-types (2.4.3) netrc (0.8.0) rest-client (1.7.2)
スクリプト
- sample_eapi.rb
#!/usr/bin/env ruby require 'arista/eapi' require 'stringio' require 'io/console' device_list = Array.new() File.open(ARGV[0]) do |f| f.each_line do |line| device_list << line end end print ("username :") username = $stdin.gets.to_s.chomp! print ("password :") password = STDIN.noecho(&:gets).to_s.chomp! device_list.flatten.each do |target| target.chomp! puts "\n--------------------- Start #{target} ---------------------\n" array_interfaces = Array.new() device = Arista::EAPI::Switch.new(target, username, password, protocol = 'http') results = device.run(["show vlan"]) unless (results.nil? || results[0].nil? || results[0][:vlans].nil? || results[0][:vlans][:"30"].nil?) then results[0][:vlans][:"30"][:interfaces].each_key do |interface_name| array_interfaces << interface_name.to_s end # create vlan & set interface switchport unless array_interfaces.nil? then results << device.run(["enable", "configure", "vlan 31"]) puts "Created vlan 31..." array_interfaces.each do |interface| results << device.run(["enable", "configure", "interface #{interface}", "switchport trunk allowed vlan add 31"]) puts "Added trunk vlan 31 to #{interface}" end results << device.run(["enable", "write memory"]) puts "wrote memory!!" end end puts "\n--------------------- End #{target} ---------------------\n" end
device_list.list はこんな感じで。
192.168.101.50 192.168.101.51 192.168.101.52 192.168.101.53
内容補足
require 'arista/eapi'で arista-eapi をインポート- 実行対象は device_list ファイルに外出し、スクリプト実行時に引数で渡す (処理はシーケンシャル)
- eAPI 認証用の username と password は標準入力で interactive に
- 結果は標準出力のみ
- 設定投入時など、エラーハンドリングは割と適当 (results という Array に格納しているだけ)
実行～状態確認
$ ruby eapi_sample.rb device_list_arista.list username :kotetsu password : --------------------- Start 192.168.101.50 --------------------- Created vlan 31...

Ansible (arista.eos Role) 版
Ansible 初心者なので、Ansibler の皆様からの突っ込み大歓迎です。
どんな Role？
Arista が公式で出している EOS(vEOS でも良い)用の Ansible role です。
github の README を見ると手っ取り早いですが、特徴は以下。
eos_commandという任意のコマンドを実行できるモジュールと、eos_<機能名>という抽象化されてコマンドを直接書く必要ないモジュール(限定的ではある)が含まれている- Ansible リモート実行仕組み(Ansible quickstart のスライド16が分かり易い)を前提としていて、EOS 側で python スクリプトが実行されるので eAPI のクライアントも EOS 側になる(127.0.0.1 にリクエスト)
本項では汎用性が高い eos_command のみを使います。
セットアップ
vEOS に ssh 公開鍵をバラまく
公式 README に従います。
Ansible では interactive にパスワードを入力させる仕組みもあるようなので、それを使う場合には本手順は不要だと思います。
実行対象全台に実行します。
今回は手動で実行しましたが、Ansible で鍵をバラまく方法もあったり(未試行)、Arista の場合 ZTP でやってしまう手もあるかと。
まずは、vEOS で SCP 転送用のユーザ(ansible)とディレクトリを作ります。
spine001>en spine001#bash Arista Networks EOS shell [kotetsu@spine001 ~]$ [kotetsu@spine001 ~]$ sudo useradd -d /persist/local/ansible -G eosadmin ansible [kotetsu@spine001 ~]$ echo password | sudo passwd --stdin ansible Changing password for user ansible. passwd: all authentication tokens updated successfully.

ansible 側から、ansible 実行時に使う公開鍵を SCP で vEOS 全台に転送します。
再起動時に ansible ユーザが作られる(& SCP 転送で使った一時的なパスワードはなくなる)ように、各 vEOS の /mnt/flash/rc.eos を作成します。
$ scp /home/kotetsu/.ssh/id_rsa.pub ansible@192.168.101.50:.ssh/authorized_keys
Password:
$ ssh ansible@192.168.101.50
Arista Networks EOS shell
[ansible@spine001 ~]$ vi /mnt/flash/rc.eos

ansible 用 hosts ファイル作成
ベストプラクティス はガン無視して、適当な work ディレクトリに作りました。
なんか Ansible オレオレベストプラクティス とかもあるし、使い方によってディレクトリ構成のベストプラクティスも変りそうですね?
[spine] 192.168.101.[50:51] [leaf] 192.168.101.[52:53] [arista_all] spine leaf

ansible から sftp で vEOS に疎通確認します。

内容補足
- eAPI 認証用の username, password は何と
vars:にベタ書き！！ roles:で今回セットアップしたarista.eosを指定hosts:で実行対象をhostsに書いたarista_allつまり全台指定vlan30.exist?という task で leaf002 は Failure になり、それ以降の設定系 task は実行されない。途中で止まらないように、当該 task でignore_errors: Trueにしている。(whenとか使って頑張ろうとしたがﾓｺﾞﾓｺﾞ)

上記には残っていませんが、初めて ansible で vEOS に playbook を流した時には library のインストールとかの task も動いて changed もカウントされます。
vEOS 実機を見ると以下の感じです。ログの設定次第で、もう少し細かい logging 情報が見られるかもです。

REST と netconf のメーカ実装動向(2014/12/14 時点)
最近はようやく構造化された情報取得が出来るアレコレを実装した NW 機器が増えてきて、利用者としては嬉しいことです。
自分が抑えている範囲では、以下の感じです。(SNMP や OpenFlow は除外)
- Juniper JUNOS：netconf と最近は一部ハイエンド機器で REST
- Brocade NOS：netconf と最近は REST
- Cisco NX-OS：netconf
- Arista EOS：REST
- F5 BIG-IP：SOAP(iControl) と最近は REST
- 日立電線 Apresia Aeos：最近は netconf (ただし、parse しにくい CLI 出力がそのまま埋め込まれているレスポンスなので、正規表現で頑張れ)
- Vyos：REST 実装予定らしい
- 故 Vyatta Core：有償版では REST 対応していたらしい
何かしら統一されるとベターですけどねー。
それと、今回紹介した 2 つはいずれも ShowNet2014 活動レポート (pdf) のスライド 62 で言うところの py-junos-eznc と同じ位置づけ(特定メーカのNetwork OS に特化して便利な機能を提供するライブラリ)ですね。
雑感
- リクエストに CLI コマンドそのまま埋め込む実装は、敬遠されそうな一方で「API 未実装だからこの機能は使えない…自分で追加実装しないと」っていう面倒ごとは起き難くて(CLI で出来ることは大抵出来る)、悪くないと思います。
- レスポンスが構造化されていると、走査が楽で良いですねー。ただ、深い階層のデータをスマートに弄るのはムズいので修行しましょう。
- 構造化されたレスポンスで…ってなると、netconf とかも良いですね。snmp はちょっと…。ただ、XML より JSON の方が人間にとっては可読性も高いし、扱い易いかも。
- 自動化系ツールでいうと、最近は chef や puppet に対応する NW 機器もポロポロ(Juniper QFX とか Arista とか)ありますね。ただ、エージェント必須型のやつは昔ながらの NW 機器で使えないし、事前準備が大変すぎて、個人的にはちょっと…。Ansible も今回とりあげた範囲では「Python 2.6 以上必須」になる動きですが、やり方次第ではそれも不要になるので許容範囲です。
- ruby の方はスクリプトでちょちょいと繰り返しや条件指定出来て良いですね。Ansible(& jinja2) はそこの表現が初心者には敷居が高かったです。
- とはいえ、システム全体を統合管理することを考えると、Ansible の Role,Module 型の作りは良いと思います。最近は何でもプラグインで追加実装できる、ってのが当然のようになってきてますよね。
- これが俺の SDN だ (きっぱり
