CLI를 사용하여 SD-WAN에서 UTD 엔진 설치 및 제거

소개

이 문서에서는 SDWAN 라우터에서 CLI를 통해 UTD(Unified Threat Defense)를 설치 및 제거하는 절차에 대해 설명합니다.

사전 요구 사항

요구 사항

다음 주제에 대한 지식을 보유하고 있으면 유용합니다.

• Cisco SD-WAN(Software-defined Wide Area Network)
• Cisco IOS® XE 명령줄 인터페이스(CLI)

사용되는 구성 요소

이 문서는 다음 소프트웨어 및 하드웨어 버전을 기반으로 합니다.

• 라우터 ISR4461/K9
• 소프트웨어 버전 17.3.4
• 컨트롤러 모드의 라우터

이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다. 이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다. 현재 네트워크가 작동 중인 경우 모든 명령의 잠재적인 영향을 미리 숙지하시기 바랍니다.

배경 정보

이 단계는 cedge가 CLI 모드에 있거나 vManage와 cedge 간에 제어 연결이 없을 때 적용해야 합니다.

그러나 제어 플레인이 있고 cedge가 vManage 모드인 경우 이 다른 문서를 검토하십시오.

개념

이 문서의 구체적인 요구 사항은 다음과 같습니다.

• Cisco vManage Release 20.3 이상
• Cisco Integrated Services Router 4431 릴리스 17.3.4

지원되는 플랫폼에 대한 자세한 내용은 SDWAN 지원 플랫폼 및 제한 사항에 대한 UTD로 이동합니다.

구성

UTD 제거

사전 검사

이것은 cedge 라우터가 이전 UTD 제거와 어떻게 다른지를 보여주는 예입니다.

* 디바이스가 컨트롤러 모드에 있고 템플릿이 첨부되어 있지 않지만 UTD 컨피그레이션이 적용됩니다.

참고: UTD 컨피그레이션을 제거하려면 먼저 해당 컨피그레이션을 제거해야 합니다.

설정

1. UTD 서비스를 중지합니다.

cedge#config-transaction
cedge(config)# app-hosting appid utd
cedge(config-app-hosting)# no start
cedge(config-app-hosting)# commit
Commit complete.

참고: UTD 상태는 시작이 적용되지 않으면 실행에서 배포됨으로 변경됩니다.

cedge#show app-hosting list
App id                                   State
---------------------------------------------------------
utd                                      DEPLOYED	
cedge#

2. UTD 구성을 제거합니다.

cedge#config-transaction

3. 확인

이것은 UTD 컨피그레이션이 제거된 후 cedge 라우터가 어떻게 작동하는지 보여주는 예입니다.

cedge#show running-config | section iox
cedge#show running-config | section VirtualPortGroup0
cedge#show running-config | section VirtualPortGroup1
cedge#show running-config | section utd
cedge#
cedge#show platform software utd global
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>

참고: 컨피그레이션이 제거되었지만 UTD에 설치된 것이 표시됩니다. 이는 예상된 결과입니다.

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

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

Total virtual services activated : 0
<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:
Name : UTD-Snort-Feature
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. UTD 엔진을 제거합니다.

팁: UTD 엔진을 제거하려면 iox 및 앱 호스팅 appid utd가 활성화되어야 합니다.

다음은 iox 및 앱 호스팅 활성화 없이 UTD를 삭제하면 발생하는 일의 예입니다.

cedge#app-hosting uninstall appid utd    >>>> No action is taken.
cedge#

다음은 UTD를 성공적으로 제거하는 예입니다.

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 20:25:50.268: %IM-6-IOX_RECONCILE_INFO: R0/0: ioxman: App-hosting application reconcile process 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#

다음을 확인합니다.

다음 명령을 실행하여 UTD가 제거되었는지 확인합니다.

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
IOS-XE Recommended UTD Version: 1.0.16_SV2.9.16.1_XE17.3

cedge#show virtual-service

구성

UTD 설치

사전 검사

UTD 지원 버전을 검토하고 bootflash에 다운로드합니다.

cedge#
cedge#show utd engine standard version
IOS-XE Recommended UTD Version: 1.0.16_SV2.9.16.1_XE17.3

cedge#

설정

1. iox 및 앱 호스팅 활성화

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. UTD 엔진을 설치합니다.

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.

*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. UTD 엔진이 설치되어 있는지 확인합니다. 다음 명령을 실행합니다.

참고: DEPLOYED 상태는 UTD가 설치되었지만 구성되지 않았음을 의미합니다. RUNNING 상태는 UTD Installed and configured를 의미합니다.

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

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. UTD를 RUNNING 상태로 만들려면 IPS/URL을 구성합니다. 이 예는 Lab의 예입니다.

5. 구성이 완료되었는지 확인합니다.

cedge#show run | section utd

다음을 확인합니다.

1. show logging을 실행하고 다음에 표시된 것과 유사한 로그를 얻었는지 확인합니다.
