Взялся за обновление ПО на коммутаторе Linksys SPS224G4, ну и задокументировать процесс...
Подключаемся через последовательный интерфейс (RS232) к консоли управления коммутатора и запускаем утилиту minicom [1]. Параметры подключения: 38400 8N1.
В процессе обновления нам понадобится настроенный TFTP-сервер. Здесь нам может пригодиться статься по настройке TFTP-сервера [2]. В дальнейшей работе отталкиваемся от того, что IP-адрес TFTP-сервера - 192.168.192.55.
TFTP-сервер скоммутирован в порт e1 коммутатора. Настроим доступ к TFTP-серверу:
SPS224G4# configure terminal
SPS224G4(config)# interface ethernet e1
SPS224G4(config-if)# switchport mode access
SPS224G4(config-if)# switchport access vlan 1
SPS224G4(config-if)# no shutdown
SPS224G4(config-if)# interface vlan 1
SPS224G4(config-if)# ip address 192.168.192.222 255.255.255.0 |
Перед обновлением прошивки, сохраним старую версию на сервере. Проверяем текущую версию ПО:
SPS224G4# show version
SW version 1.0.2 ( date 18-Nov-2008 time 12:38:16 )
Boot version 1.0.2 ( date 13-Nov-2007 time 14:11:51 )
HW version 00.03.00 |
Выполним копирование текущей версии software:
SPS224G4# copy image tftp://192.168.192.55/SPS224G4_1.0.2.ros
18-Nov-2008 17:51:11 %COPY-I-FILECPY: Files Copy - source URL flash://image destination URL tftp://192.168.192.55/SPS224G4_1.0.2.ros

Теперь обратная процедура - загрузка новой версии прошивки из файла ls_sps2xx_bx-10600.ros [3] (можно скачать по этой ссылке) на коммутатор:
SPS224G4# copy tftp://192.168.192.55/ls_sps2xx_bx-10600.ros image 18-Nov-2008 17:59:04 %COPY-I-FILECPY: Files Copy - source URL tftp://192.168.192.55/ls_sps2xx_bx-10600.ros destination URL flash://image !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 18-Nov-2008 18:00:17 %COPY-N-TRAP: The copy operation was completed successfully ! Copy: 3936707 bytes copied in 00:01:13 [hh:mm:ss] |
Перезагружаем коммутатор и проверяем версию прошивки:
SPS224G4# show version
SW version 1.0.6 ( date 29-Aug-2011 time 20:05:47 )
Boot version 1.0.2 ( date 13-Nov-2007 time 14:11:51 )
HW version 00.03.00 |
На этом процедуру обновления ПО на коммутаторе Linksys SPS224G4 считаем выполненой. Версию firmware обновили с версии 1.0.2 до версии 1.0.6.
