После введения команд из блока конфигурации базового функционала на маршрутизаторе взведётся авария:
Core-R1
0/ME5200S:Core-R1# show alarms Wed Oct 15 00:36:48 2025 ID Code Type Device Severity Duration Description -------- ------------------------------------------------- ------------- -------- --------- ----------- ------------ 1 System has an unapplied configuration alarm trap local info 00h18m23s Some configuration will be applied after system reload.
Это результат изменения блока hw-module. Конфигурация этого модуля применяется после перезагрузки маршрутизатора. Целесообразно это сделать в самом начале.
В процессе конфигурации или по его окончании рекомендуется проконтролировать результаты настройки и корректность получаемых результатов.
Ниже на примере маршрутизатора Core-R1 показаны результаты некоторых диагностических команд.
Все настроенные интерфейсы сконфигурированы корректно, подняты и имеют все записи в arp-таблице:
