Имеется 2 контроллера WLC в составе кластера Active/Standby с firewall failover для резервирования с резервированием функционала WLC. Необходимо обновить ПО без прерывания сервисов в схеме.

Необходимо подключиться к обновляемому устройству по консольному кабелю или, предварительно настроив доступ по SSH (Подробнее см. в разделе Настройка доступа SSH, Telnet справочника команд CLI).)

Загружаем Загрузите ПО (firmware-файл) на сервисный маршрутизатор ESR c использованием одного из протоколов удаленной загрузки файлов.

Блок кода
wlc-2# copy tftp://<tftp-server-ip>:/<firmware-file> system:firmware \|******************************************\| 100% (0B) Firmware updated successfully.

Далее необходимо выбрать образ ПО обновленной версии для следующей загрузки. Перезагрузить сервисный маршрутизатор.

После перезагрузки видим будет показано сообщение о том, что наши версии с мастером не совпадaют:

Блок кода
2026-02-26T10:07:08+07:00 %CLUSTER-W-SYNC_FIRMWARE_WARN: unit 1 'wlc-1' SW version not synced with local

Также, проверить синхронизацию можно командой командой show cluster sync status:

Блок кода
System part Synced ---------------------- ------ candidate-config Yes running-config Yes SW version No licence Yes licence (After reboot) Yes date Yes

2. Теперь для проверки корректности работы на новом ПО необходимо перевести наш Backup-маршрутизатор в активный, т.е. перенести нагрузку на него.
Для этого применяем примените команду clear vrrp-state на Active на Active маршрутизаторе.

Блок кода

wlc-1# clear vrrp-state 
2026-02-26T10:10:34+07:00 %VRRP-I-INSTANCE: VRRP5 Entering BACKUP state
2026-02-26T10:10:34+07:00 %VRRP-I-INSTANCE: VRRP9 Entering BACKUP state

2026-02-26T10:10:34+07:00 %VRRP-I-INSTANCE: VRRP6 Entering BACKUP state

УбеждаемсяУбедитесь, что сменилась активная роль в кластере командой — командой show cluster status:

Блок кода

wlc-30-1# sh cluster status 
Unit   Hostname               Role         MAC address         State            IP address

Также можно убедиться, что наши сервисы не прервались и мастерство сменилось командой — командой show high-availability state:

Блок кода

3. В случае если весь требуемый функционал на актуальной версии ПО работает корректно, обновляем обновите оставшееся устройство командой sync cluster system force на active force на active устройстве, она начнет процесс синхронизации: автоматически обновит ПО standby устройства и перезагрузит.

Блок кода

2026-02-26T10:22:15+07:00 %CLUSTER-I-SYNC_SYSTEM_INFO: from unit 1 'wlc-30-1': system will be rebooted to apply all changes

Если Если необходимо обратно вернуть мастерство - – снова применяем команду примените команду clear vrrp-state на Active маршрутизаторе.

4. В противном случае, возвращаем верните мастерство на устройство, которое работает на старом ПО и снова выполняем выполните команду sync cluster system force для отката ПО на втором устройстве.
