Extreme switch stack 구성 – 수동(?) 설정.

익스트림 스위치 스택 구성 – 수동 구성

스위치 모델: x440-24p 2대.

이전 글에서는 익스트림 스위치의 스택을 easysetup 을 사용하여 구성했다.

스택 케이블 연결후, 모든 스위치에서

* X440-24p.2 # configure stacking protocol standard
This command will take effect at the next reboot of the specified node(s).

enable stacking 명령을 내린후, easy setup 에서 No를 선택한다.(기본값임)

* X440-24p.3 # enable stacking
You have not yet configured all required stacking parameters.
Would you like to perform an easy setup for stacking operation? (y/N)

Stacking has been enabled as requested.
This command will take effect at the next reboot of the specified node(s).

스택 구성을 확인 해 보면 아래처럼 보인다.

* X440-24p.1 # show stacking
Stack Topology is a Daisy-Chain
This node is not in an Active Topology
Node MAC Address    Slot  Stack State  Role     Flags
------------------  ----  -----------  -------  ---
*00:04:96:8b:f8:1d  -     Disabled     Master   ---
 00:04:96:8f:ee:61  -     Disabled     Master   ---
* - Indicates this node
Flags:  (C) Candidate for this active topology, (A) Active Node
        (O) node may be in Other active topology

Master 노드로 사용할 스위치에서 아래 과정을 진행한다. daisy-chain 구성에서 master node는 2번 포트에 연결된 스위치가 되어야 한다고 한다.

스택 MAC address 설정

위에서 * 표시가 되어 있는 스위치가 콘솔 연결된 스위치 이므로, MAC 주소를 확인할 수 있다.

* X440-24p.2 # configure stacking node-address 00:04:96:8b:f8:1d mac-address

슬롯 번호 설정

* X440-24p.3 # configure stacking node-address 00:04:96:8b:f8:1d slot-number 1
This command will take effect at the next reboot of the specified node(s).
* X440-24p.4 # configure stacking node-address 00:04:96:8f:ee:61 slot-number 2
This command will take effect at the next reboot of the specified node(s).

redundancy 설정. master 노드 장애시 backup 노드 지정. 여기서는 두대로 구성하므로, minimal을 선택했음.

* Slot-1 Stack.6 # configure stacking redundancy ?
  maximal         Maximal redundancy (master-capability on all nodes)
  minimal         Minimal redundancy (master-capability on two nodes)
  none            No redundancy (master-capability on one node)

* Slot-1 Stack.6 # configure stacking redundancy minimal
This command will take effect at the next reboot of the specified node(s).

재부팅 한다. reboot stack-topology 명령을 내리면 연결된 모든 스위치가 재부팅된다.

* X440-24p.8 # reboot stack-topology
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!
The system is going down NOW!
Sending SIGKILL to all processes
Requesting system reboot

재부팅후, 마스터 노드에서 스택 구성을 확인 해 보면,

* Slot-1 Stack.1 # show stacking
Stack Topology is a Daisy-Chain
Active Topology is a Daisy-Chain
Node MAC Address    Slot  Stack State  Role     Flags
------------------  ----  -----------  -------  ---
*00:04:96:8b:f8:1d  1     Active       Master   CA-
 00:04:96:8f:ee:61  2     Active       Backup   CA-
* - Indicates this node
Flags:  (C) Candidate for this active topology, (A) Active Node
        (O) node may be in Other active topology

백업노드에서 확인. 백업노드의 프롬프트는 #가 아니라 >로 표시된다.

* Slot-2 Stack.1 >
* Slot-2 Stack.1 > show stacking
Stack Topology is a Daisy-Chain
Active Topology is a Daisy-Chain
Node MAC Address    Slot  Stack State  Role     Flags
------------------  ----  -----------  -------  ---
 00:04:96:8b:f8:1d  1     Active       Master   CA-
*00:04:96:8f:ee:61  2     Active       Backup   CA-
* - Indicates this node
Flags:  (C) Candidate for this active topology, (A) Active Node
        (O) node may be in Other active topology

이제, 마스터 노드에서 필요한 설정을 하고 사용하면된다.
