extreme switch stack 구성 – EasySetup 사용.
* 작업 스위치 모델: x440-24p
* 공장초기화 상태에서 진행함.
1. 스택 케이블 연결전 확인사항.
Stack 구성을 하면 설정이 삭제되므로, 명령을 내리기 전에 설정을 백업 받아둔다.
연결전 모든 스위치의 라이센스, OS 버전이 동일해야 한다.
OS 버전이 다르다면 동일하게 맞추어준다.(OS 업그레이드는 https://blog.boxcorea.com/wp/archives/2585 를 참고)
각각의 스위치에서 아래 명령으로 확인 한다.
라이센스 확인
* X440-24p.1 # show license
Enabled License Level:
Edge
Enabled Feature Packs:
None
OS버전확인

2. 스택 케이블을 연결하고(매뉴얼에는 전원을끄고 연결하라고 나오지만 전원켠 상태에서 연결했다) 상태를 확인한다. 케이블은 아래 사진처럼 교차로 연결한다.
* X440-24p.4 # show stacking
Stack Topology is a Daisy-Chain

(O) node may be in Other active topology
3. 스택으로 구성 할 모든 스위치에서 아래 명령을 내린다.
* X440-24p.5 # configure stacking protocol standard This command will take effect at the next reboot of the specified node(s).
4. Master 노드로 사용할 스위치에 콘솔 접속하여 스택을 활성화한다. (EasySetup 을 사용하는 경우)
* X440-24p.2 # enable stacking You have not yet configured all required stacking parameters. Would you like to perform an easy setup for stacking operation? (y/N) Yes Executing "configure stacking easy-setup" command... For every node in the 2-node stack, this command will: - enable stacking - configure a stack MAC address - choose and configure a slot number (this node will be assigned to slot 2) - configure redundancy to none (slot 1 will be the master node) - configure the stacking protocol to enhanced Upon completion, the stack will automatically be rebooted into the new configuration. Warning: If stacking is already configured, this command will alter that configuration. Warning: This stack is a daisy chain. It is highly recommended that the stack be connected as a ring before running this command. Warning: There are unsaved configuration changes. You may wish to save them before proceeding. Do you wish to proceed? (y/N) Yes Stacking configuration is complete. Rebooting...
이제 재부팅이 끝나고 나면 스위치 전면 ‘Stack No.’ 에 노드 번호가 표시된다.
로그인 프롬프트가 login 으로 바뀔때까지 지루하지만 기다려야한다.
(pending-AAA) login: Authentication Service (AAA) on the master node is now available for login. login:
노드 1로 콘솔 접속하면 easysetup이 실행된다. (기본값을 입력하여 끝내고) 스택 상태를 확인해보면,

노드 1에서 설정 진행후 저장하고 재부팅하고 사용하면 된다.
* Slot-1 Stack.6 # save No default configuration database has been selected to boot up the system. Save configuration will set the new configuration as the default database. Do you want to save configuration to primary.cfg? (y/N) Yes Saving configuration on master ...................... done! Saving configuration on Standbys (Slots: 2). Configuration saved on Standby (Slot 2): done! The selected configuration file is now "primary.cfg". By default, this file will be used for saving the configuration which will take effect after the next switch reboot. Slot-1 Stack.7 # reboot Are you sure you want to reboot the stack? (y/N) Yes
5. 스택 해체는 아래처럼!
* Slot-1 Stack.6 # disable stacking This command will take effect at the next reboot of the specified node(s). * Slot-1 Stack.7 # reboot No default configuration database has been selected to boot up the system. Save configuration will set the new configuration as the default database. Do you want to save configuration changes to currently selected configuration file (primary.cfg) and reboot? (y - save and reboot, n - reboot without save, <cr> - cancel command) Yes Saving configuration on master ................... done!
