Я использую OpenWRT (пробовал все 3 последние версии) в TP-LINK WDR3600 с установленными утилитами snmpd и snmp. Я могу получить (хотя кажется, что MIB отсутствуют), но не могу установить OID.

Есть подсказки? Спасибо
OID, установленные в файле конфигурации, становятся доступными только для чтения, поэтому iso.3.6.1.2.1.1.5.0 доступен для записи, только если sysName не задано в config. Чтобы иметь значимые MIB, которые могли писать в них и производить эффект, нужно загрузить их или расширить сам агент.
