Сброс настроек на маршрутизаторе Mikrotik RB751U-2HnD

Перед настройкой любого сетевого оборудования ранее находившегося в эксплуатации необходимо убедиться в том что старые параметры не используются. Проще всего выполнить процедуру сброса настроек, т.н. factory default. На маршрутизаторах Mikrotik RB для этого достаточно, подключившись по telnet к командной строке маршрутизатора, выполнить команду: /system reset-configuration

После сброса маршрутизатор по умолчанию содержит следующую конфигурацию:

#| ether1 is renamed to ether1-gateway
#| DHCP client and masquerade is set on ether1-gateway
#| ether2 is renamed to ether2-master-local and configured as switch master port for ether3-ether5
#| ether2-master-local and wlan1 are bridged
#| wireless is set as access point in 2412MHz using both chains and extension channel enabled.
#| IP address 192.168.88.1/24 and DHCP server is set on bridge interface
#| DHCP servers address pool is 192.168.88.10-192.168.88.254
