Cisco developer sandbox lab

Cisco sandbox

sandbox 提供給咱們一個免費的開發平臺，能夠基於該平臺作不少和思科網絡設備、軟件有關的代碼開發、腳本測試、自動化配置等工做：

• 學習研究網絡知識，提高本身
• 學習研究思科設備、軟件提供的API接口
• 全天候支持
• 提供虛擬機、模擬器、以及真實網絡設備等選擇
• 最重要的是，以上全免費

首次進入sandbox，連接爲：devnetsandbox.cisco.com/RM/Topology，登陸便可使用，支持不少種登陸方式：

Sandbox 支持多種登陸方式

Sandbox提供2種模式的lab

截止至2018年末，sandbox提供了約68個labs，按運行申請模式不一樣分爲：

• Regular 58個，須要預留單獨使用，個性化配置
• Always_On 10個，共享模式，一直在線提供訪問，不容許修改配置

Always_On 特色

該類lab比較簡單，爲了解cisco sandbox提供一種快捷的實現方式：

• 不須要申請和預留，隨時可使用
• 無需初始化配置
• 共享訪問
• API支持

若是須要個性化的設置和複雜的網絡拓撲結構，則須要申請使用regular sandbox。

可編程的NX-OS lab

NX-OS Programmability是其中一個Always on sandbox，該lab提供nexus 3k/9K 的各類不一樣的設備訪問方式，實現：

• 測試設備的可重複利用的、可編程的腳本自動化工具
• 測試NXAPI接口，包括CLI、REST
• 測試netconf
• YANG model
• restconf（草稿標準）

咱們能夠經過首頁找到該LAB，詳細的信息請訪問網頁。

簡單的訪問方法

因爲是共享lab，訪問方式比較簡單和固定：

• Nexus 9000v Host : sbx-nxos-mgmt.cisco.com
• SSH Port: 8181
• NETCONF Port: 10000
• NXAPI Ports: 80 (http) & 443 (HTTPS)
• RESTCONF Port : 443 (HTTPS)
• Credentials（demo帳戶）:
  • Username: admin
  • Password: Admin_1234!

若是須要嘗試一下經過nxapi訪問設備，能夠在瀏覽器中輸入地址：sbx-nxos-mgmt.cisco.com ，使用上述「demo帳戶」的用戶名和密碼登陸，便可以顯示Nexus 9K sandbox。

如圖顯示命令"show interface brief"的輸出：

經過NXAPI CLI訪問設備，並顯示命令：show interface brief

咱們也可使用ssh登陸設備

ssh admin@sbx-nxos-mgmt.cisco.com -p 8181
