本文檔介紹通過SDWAN路由器的CLI安裝和解除安裝統一威脅防禦(UTD)的過程。
思科建議您瞭解以下主題:
本檔案是根據以下軟體和硬體版本所編制:
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除(預設)的組態來啟動。如果您的網路運作中,請確保您瞭解任何指令可能造成的影響。
當cedge處於CLI模式或vManage和cedge之間沒有控制連線時,需要應用這些步驟。
但是,如果您有控制平面,並且您的邊緣處於vManage模式,則繼續檢視此其他文章。
本文檔的具體要求包括:
有關支援的平台的更多資訊,請導航至SDWAN支援的平台和限制的UTD。
以下是解除安裝UTD之前的cedge路由器示例。
*裝置處於控制器模式,未連線任何模板,但應用了UTD配置。

UTD Global state
=========================
Engine : Standard
Global Inspection : Disabled
Operational Mode : Intrusion Detection
Fail Policy : Fail-open
Container technology : LXC
Redirect interface : Not specified
UTD interfaces
No interfaces are protected by UTD
<snipped>
附註:雖然組態已移除,UTD仍會顯示installed。這是意料之中的。
cedge#show utd engine standard version
UTD Virtual-service Name: utd
IOS-XE Recommended UTD Version: 1.0.16_SV2.9.16.1_XE17.3
IOS-XE Supported UTD Regex: ^1\.0\.([0-9]+)_SV(.*)_XE17.3$

<snipped>
cedge#show app-hosting list
The process for the command is not responding or is otherwise unavailable >>>> Expected because UTD config was removed but UTD engine remains installed
** Before to remove Configuration **
cedge#show virtual-service version name utd running
Virtual service utd running version:

Version : 1.0.16_SV2.9.16.1_XE17.3
** After configuration is removed **
cedge#
cedge#show virtual-service version name utd running
Virtual service utd running version:
Name : UTD-Snort-Feature
Version : None
4.刪除UTD引擎。
提示:您需要啟用iox和應用宿主appid utd才能解除安裝UTD引擎。
以下範例顯示了在未啟用iox和應用託管啟用的情況下刪除UTD會發生的情況。
cedge#app-hosting uninstall appid utd >>>> No action is taken.
cedge#
以下是成功解除安裝UTD的範例。
cedge#config-transaction
cedge(config)# iox
cedge(config)# app-hosting appid utd
cedge(config-app-hosting)# commit
Commit complete.
cedge(config-app-hosting)#
*Mar 3 20:25:24.889: %UICFGEXP-6-SERVER_NOTIFIED_START: R0/0: psd: Server iox has been notified to start

*Mar 3 20:25:51.956: %IM-6-IOX_ENABLEMENT: R0/0: ioxman: IOX is ready.
cedge#
cedge#app-hosting uninstall appid utd
Uninstalling 'utd'. Use 'show app-hosting list' for progress.
cedge#
*Mar 3 20:26:31.653: %VIRT_SERVICE-5-INSTALL_STATE: Successfully uninstalled virtual service utd
*Mar 3 20:26:32.706: %IM-6-INSTALL_MSG: R0/0: ioxman: app-hosting: Uninstall succeeded: utd uninstalled successfully
cedge#
運行以下命令以驗證是否刪除了UTD。
cedge#show app-hosting list
No App found
cedge#show virtual-service version name utd running
% Error: Virtual-service utd is not found
cedge#show utd engine standard version

cedge#show virtual-service
Virtual Service Global State and Virtualization Limits:

<snipped>
檢視UTD支援的版本,然後將其下載到bootflash中。
cedge#
cedge#show utd engine standard version
IOS-XE Recommended UTD Version: 1.0.16_SV2.9.16.1_XE17.3

cedge#
1.啟用iox和應用託管。
cedge#config-transaction
cedge(config)# iox
cedge(config)# app-hosting appid utd
cedge(config-app-hosting)# commit
Commit complete.
cedge(config-app-hosting)#
*Mar 3 20:25:24.889: %UICFGEXP-6-SERVER_NOTIFIED_START: R0/0: psd: Server iox has been notified to start

*Mar 3 20:25:51.956: %IM-6-IOX_ENABLEMENT: R0/0: ioxman: IOX is ready.
cedge#
2.安裝UTD引擎。
cedge#app-hosting install appid utd package bootflash:secapp-utd.17.03.04a.1.0.16_SV2.9.16.1_XE17.3.x86_64.tar
Installing package 'bootflash:secapp-utd.17.03.04a.1.0.16_SV2.9.16.1_XE17.3.x86_64.tar' for 'utd'. Use 'show app-hosting list' for progress.
cedge#
*Mar 3 21:07:43.529: %VMAN-5-PACKAGE_SIGNING_LEVEL_ON_INSTALL: R0/0: vman: Package 'secapp-utd.17.03.04a.1.0.16_SV2.9.16.1_XE17.3.x86_64.tar' for service container 'utd' is 'Cisco signed', signing level cached on original install is 'Cisco signed'
*Mar 3 21:07:56.332: %VIRT_SERVICE-5-INSTALL_STATE: Successfully installed virtual service utd
*Mar 3 21:07:56.922: %IM-6-INSTALL_MSG: R0/0: ioxman: app-hosting: Install succeeded: utd installed successfully Current state is deployed
cedge#
3.確保已安裝UTD引擎。運行下一命令。
附註:DEPLOYED狀態指已安裝但未配置的UTD。RUNNING state表示UTD Installed and configured。
cedge#show app-hosting list
App id State
---------------------------------------------------------
utd DEPLOYED
cedge#show virtual-service version name utd running
Virtual service utd running version:
Name : UTD-Snort-Feature
Version : None >>>> "None", it is expected due to the fact that no config yet
cedge#show utd engine standard version
UTD Virtual-service Name: utd
IOS-XE Recommended UTD Version: 1.0.16_SV2.9.16.1_XE17.3
IOS-XE Supported UTD Regex: ^1\.0\.([0-9]+)_SV(.*)_XE17.3$
UTD Installed Version: 1.0.16_SV2.9.16.1_XE17.3 >>>> UTD Package installed
cedge#
cedge#show virtual-service
Virtual Service Global State and Virtualization Limits:
Infrastructure version : 1.7
Total virtual services installed : 1 >>>> Installed 1 but Activated 0 as expected
Total virtual services activated : 0
4.要使UTD處於運行狀態,請繼續配置IPS/URL。這是來自實驗室的一個示例。
