重置身份服务引擎(ISE)情景可视性

简介

本文档介绍如何在ISE分布式部署上执行情景可视性的重置和同步。

问题

如果情景可视性GUI加载失败，并出现错误消息“无法加载情景可视性页面”或仪表板计数器为空，则建议执行此过程。无法添加MAC地址，错误为“Unable to create the endpoint， Endpoint XX:XX:XX:XX:XX:XX exists。当Context Visibility数据库与该终端的Oracle数据库不同步时，会出现这种情况。

本文档介绍如何在ISE分布式部署中执行情景可视性的重置和同步以解决这些问题。

解决方案

通过控制台或SSH连接到主管理节点（为了简洁，某些输出已做相应修改），然后执行application configure ise命令，后跟选项[20] Reset Context Visibility' 并同意继续y。 不要回答最后一个问题：

primary-node/admin# application configure ise

Selection configuration option
~
[20]Reset Context Visibility
[21]Synchronize Context Visibility With Database
~

20
This will remove all data from Context Visibility. Do you want to proceed [y/n]: y
Checking ISE persona
 - Done
Reset of indexing engine on this node needs to be run only after running it on Secondary Admin Node(secondary-node)
Is reset indexing engine started on Secondary Admin Node(secondary-node) [ Y/N ] :

如果最后一个问题没有回复，请打开SSH或控制台到辅助管理节点，然后执行命令application configure ise，然后执行选项[20] Reset Context Visibility并同意继续y，请不要回复最后一个问题。

secondary-node/admin# application configure ise

Selection configuration option
~
[20]Reset Context Visibility
[21]Synchronize Context Visibility With Database

使用Y在主管理节点的SSH或控制台中继续回答最后一个问题，并且没有回复。

[0]从配置菜单退出，并使用Y在辅助管理节点的SSH或控制台中继续。

[0]退出配置菜单。

在两个节点上执行情景可视性重置后，继续在主管理节点上执行同步：

primary-node/admin# application configure ise

Selection configuration option
~
[20]Reset Context Visibility
[21]Synchronize Context Visibility With Database
~

21
This will synchronize Context Visibility with database. Do you want to proceed [y/n]: y

[0]退出配置菜单。

确认索引引擎正在两个管理节点上运行。
