重置身份服務引擎(ISE)情景可視性

簡介

本文檔介紹如何在ISE分散式部署上執行情景可視性的重置和同步。

問題

如果情景可視性GUI無法載入，並出現錯誤消息「無法載入情景可視性頁面」或儀表板計數器為空時所執行的過程。無法新增MAC地址，錯誤為「Unable to create the endpoint， Endpoint XX:XX:XX:XX:XX:XX exists」。當Context Visibility資料庫與該終結點的Oracle資料庫不同步時，會發生這種情況。

本文檔介紹如何在ISE分散式部署中執行情景可視性的重置和同步以解決這些問題。

解決方案

通過控制檯或SSH連線到主管理節點（為簡潔起見，省略了某些輸出），然後使用application configure ise命令，後跟選項[20] Reset Context Visibility並同意繼續y。 不要回答最後一個問題：

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 ] :

如果最後一個問題沒有回覆，請開啟SSH或控制檯到輔助管理節點，然後使用命令application configure ise，然後使用選項[20] Reset Context Visibility並同意繼續y。不要回答最後一個問題。

secondary-node/admin# application configure ise

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

如果沒有對最後一個問題的回覆，請使用Y在Primary Administration Node的SSH或控制檯中繼續。

[0]退出配置選單，使用Y在輔助管理節點的SSH或控制檯中繼續。

在兩個節點上執行上下文可見性重置後，在主管理節點上繼續同步：

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]退出配置選單。

確認索引引擎正在兩個管理節點上運行。
