在SD-WAN上配置SD-AVC

简介

本文档介绍如何在软件定义广域网(SD-WAN)上配置软件定义应用可视性与可控性(SD-AVC)。

先决条件

要求

Cisco 建议您了解以下主题：

• SD-WAN
• SD-AVC

Cisco vManage的虚拟机必须具备以下最低资源：

• RAM:32 GB
• 存储：500 GB
• vCPU:16

使用的组件

本文档中的信息基于以下软件和硬件版本：

• Cisco vManage 20.3.x版或更高版本。
• vManage版本20.6.3
• vBond版本20.6.3
• vSmart版本20.6.3
• 集成多业务路由器(ISR)4321/K9版本17.5.1a

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。

背景

什么是SD-AVC?

Cisco SD-AVC是思科应用可视性控制(AVC)的组件。 AVC将应用识别和性能监控功能整合到路由设备中，这些功能传统上作为专用设备提供。它作为集中式网络服务工作，可与网络中的特定设备协同工作。 

有关详细信息，请参阅SD-AVC功能和优点。

什么是思科云连接器？

Cisco Cloud Connector是思科提供的云服务，可改善流量分类。它使用有关公共Internet站点和服务使用的服务器地址的最新可用信息来改进SD-AVC流量分类。

配置

启用云连接器

1.打开Cisco API控制台，然后单击 My Apps & Keys.

注：设备托管的SD-AVC网络需要访问思科SD-AVC云服务器域:api.cisco.com、cloudsso.cisco.com、prod.sdavc-cloud-api.com。

2.单击 Register a New App 如图所示.

3.在 Name of your application 字段中，输入应用程序的描述性名称。

4.检查 Client Credentials 复选框。

5.检查 Hello API 复选框。

6.选中此复选框以同意服务条款。

7.单击 Register.Cisco API Console页面显示Client ID和Client Secret详细信息。请将此页保持打开以完成此图中所示的过程。

在vManage上启用SD-AVC云连接器

1.在vManage GUI部分，导航至 Administration > Settings > SD-AVC Cloud Connector 并点击 Edit.

2.对于SD-AVC云连接器，请点击 Enabled 单选按钮.在“启用云连接器”部分生成的这些字段中输入值，如图所示。

• 客户端ID
• 客户端密码
• 单位名称
• 亲和力
• 遥测（可选）

3.单击 Save 并验证此图中所示的通知。

在vManage上启用SD-AVC

1.导航至 Administration > Cluster Management > Service Configuration.点击 (...) More Actions 选择 Edit.

注意：请勿使用VPN 0隧道/传输或VPN 512接口启用SD-AVC。 可以使用vpn 0中的集群接口。 

2.在vManage IP Address部分，点击IP地址。  在VPN 0中选择非隧道IP地址。输入您的凭证，请检查 Enabled SD-AVC 复选框，然后单击 Update,如图所示.

3.确认更新后，单击 OK 以便重新启动设备，如图所示。

4.在vManage重新启动后，导航至 Administration > Cluster Management > Service Reachability.出现SD-AVC Reachable.

策略配置

启用SD-AVC后，您需要创建本地化策略并启用应用可视性。

1.导航到vManage GUI，然后选择 Configuration > Policies > Localized Policy > Add Policy.

2.导航至 Policy Overview,.如果 Policy Settings 部分，请检查 Application 复选框，然后单击 Save Policy.

3.导航至 Configuration > Templates.确定cEdge的模板名称，单击 (...) More Actions 选择 Edit 如图所示.

4.导航至 Additional Templates.从 Policy 下拉列表中，选择以前创建的本地化策略。

5.保存模板。

验证

使用本部分可确认配置能否正常运行。

1.在cEdge设备中，输入此命令以验证cEdge设备与SD-AVC控制器之间的连接。

故障排除

本部分提供的信息可用于对配置进行故障排除。

在vManage日志中，验证以下路径：

/var/log/nms/vmanage-server.log
/var/log/nms/containers/sdavc/avc/sdavc_application.log

输入此命令：

request nms container-manager {status | diagnostics}

在cEdge Cisco IOS^® XE中，输入以下命令：

Router#show avc sd-service info connectivity 
show avc sd-service info {export | import}
