在SMC日志中解决"；无法找到"；的密钥

简介

本文档介绍如何解决 Secure Network Analytics Manager Central Management.

先决条件

要求

本文档没有任何特定的要求。

使用的组件

本文档中的信息基于以下软件和硬件版本：

• Secure Network Analytics Manager 版本7.1.1或更高版本

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

此问题出现在内部服务中 Central Management 需要凭证，例如 SNMP v3. 

上未显示错误 Central Management 页面本身。

此部署具有主管理器和辅助管理器。

此 /lancope/var/logs/containers/svc-central-management.log 主Manager上的文件包含行条目 "unable to find secret for" 条目。

问题

在主管理器中看到此错误 /lancope/var/logs/containers/svc-central-management.log 文件，当配置更改辅助管理器配置时。任何可配置为使用身份验证的中央管理配置部分均可发生这种情况。

在主Manager上，检查 /lancope/var/services/cm/configuration/{idofsecondarysmcdirectory}/config.json 文件。使用 jq . /lancope/var/services/cm/configuration/idofsecondarysmcdirectory/config.json 命令。

primary-smc#: jq .configurableElements.snmpAgent /lancope/var/services/cm/configuration/{idofsecondarysmcdirectory}/config.json

解决方案

导航至 Central Management > Actions > Edit Appliance Configuration > Network Services 然后输入 Encryption Password  和 Authentication Password  选择SNMP版本V3时，“SNMP代理”部分中的值。完成后，选择 Apply Settings.

SNMPv3代理配置
