Catalyst 9000交换机上的SLP智能传输故障排除
简介
本文档介绍如何使用Catalyst 9000交换机上的智能传输对使用策略(SLP)的智能许可进行故障排除。
先决条件
要求
思科建议您了解并熟悉以下主题：
-
在Cisco IOS® XE设备上使用策略的智能许可。
使用的组件
本文档中的信息基于以下软件和硬件版本：
- Catalyst 9200
- Catalyst 9300
- Catalyst 9400
- Catalyst 9500
- Catalyst 9600
- Cisco IOS XE 17.9.1及更高版本
注意：有关在其他思科平台上启用这些功能所使用的命令，请参阅相应的配置指南。
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。
背景信息
使用策略的智能许可是智能许可的增强版本，其设计的主要目标是提供许可解决方案，确保您的网络运营保持不间断。它不是破坏性的，而是建立合规性关系，说明您购买和使用的硬件和软件许可证。
为使智能许可报告正常工作，Catalyst 9000交换机与思科智能软件管理器(CSSM)连接以报告许可证使用情况。CSSM是一个集中式平台，用于管理所有思科软件许可证并审核使用情况，这有助于规划未来的许可需求。
Catalyst 9000交换机可通过多种拓扑连接到CSSM，但本文档重点介绍交换机直接连接到CSSM的特定拓扑。这意味着交换机必须能够与托管在Internet上的CSSM连接并建立连接。
在此直接连接拓扑中，有两个传输选项：Smart Transport和Call Home，建议使用Smart Transport。此外，智能传输支持使用HTTPS代理并允许选择特定VRF来处理与CSSM的智能许可通信。
使用智能传输时，Catalyst 9000交换机在HTTPS消息中与CSSM以JavaScript对象表示法(JSON)格式交换许可证使用信息。此信息称为RUM报告，由交换机发送，来自CSSM的响应称为ACK。
此拓扑的最小报告频率被限制为一天。这意味着产品实例每天最多发送一个RUM报告，从而防止针对某些许可证生成和传输过多的报告。这有助于解决因RUM报告超量生成导致的内存相关问题和系统减速。
如果需要，您可以在特权EXEC模式下使用license smart sync命令来覆盖此限制
配置
按照以下步骤使用智能传输配置SLP:
-
将智能配置为传输类型，并使用默认URL。
Switch#configure terminal
Switch(config)#license smart transport smart
Switch(config)#license smart url default
注意：如果将VRF用于智能传输
license smart vrf，则需要配置。 -
为DNS解析和HTTP客户端连接配置DNS服务器和源接口。
Switch(config)#ip domain lookup
Switch(config)#ip name-server 10.31.104.74
Switch(config)#ip domain name cisco.com
Switch(config)#ip domain lookup source-interface Vlan10
注意：如果将VRF用于智能传输，则需要使用这些命令的VRF变体。
-
如果需要，请配置HTTPS代理。
Switch(config)#license smart proxy address 192.168.217.105
Switch(config)#license smart proxy port 80
注意：可以使用代理服务器的IP地址或主机名配置代理服务器。
-
在虚拟帐户中生成令牌。要完成此步骤，请按照本文档中概述的流程操作。
-
在交换机上安装信任代码。
Switch#license smart trust idtoken NGFkODgzMGUtZmNkMS00NTRjLWI5MjUtYjI0YWYzZjU1ZGQzLTE3NDAyNjU5%0AODA0NTV8VXVHVjdvVjByejY1aVZYa0lCVkl12345FSk9WZTdDb3lhZEZT%0ANjkyST0%3D%0A all force [OK]
使用CSSM成功建立信任后，将显示类似如下的系统日志。
*Jan 24 23:19:05.144: %SMART_LIC-6-TRUST_INSTALL_SUCCESS: A new licensing trust code was successfully installed on P:C9300-48UN,S:<SN>.
此外
show license status，还显示信任代码安装时间。Switch#show license status | i Trust Trust Code Installed: Jan 24 23:19:05 2025 UTC <--- Trust code was installed
最后，虚拟帐户事件日志显示交换机已添加。
显示设备的虚拟帐户事件日志。
故障排除
如果使用CSSM建立信任失败，将显示指示失败原因的系统日志。
*Jan 24 15:17:46.341: %SMART_LIC-3-COMM_FAILED: Communications failure with the Cisco Smart Software Manager (CSSM) : <Reason>
通信失败的可能原因包括：
-
无法解析服务器主机名/域名：DNS未解析智能传输URL或代理服务器主机名。验证DNS服务器的名称解析配置和可达性。
-
连接超时：已尝试连接，但没有响应。使用数据包捕获验证正在建立与CSSM的HTTPS连接，并检查设备（如代理服务器或防火墙）是否正在阻止连接。如果使用代理服务器，请确保使用正确的端口。
按照以下步骤和验证命令对使用智能传输的SLP进行故障排除：
-
验证智能许可事件日志。

要验证交换机是否正在与CSSM建立HTTPS连接，可以捕获数据包。这是使用代理服务器成功连接的数据包捕获示例。

使用代理服务器成功与CSSM建立HTTPS连接的数据包捕获。 -
如果数据包捕获显示HTTPS连接正在尝试建立，但失败，则可能是因为TLS或SSL握手失败。这些调试可用于进一步调查。

如果任何时候需要从交换机删除已安装的信任代码，则可以执行智能许可工厂重置。此过程需要重新加载。重置出厂设置后，可以安装新的信任代码。使用此命令可删除所有许可信息，包括策略。
