При запросе таблицы всё отображается корректно вроде бы

Но вот, когда запрашиваю конкретный OID, получаю ошибку

snmpget -v 1 -c public localhost ROSCHAT-M0-MIB::serviceState.2
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: ROSCHAT-M0-MIB::serviceState.2

Подскажите, как формировать таблицу, чтобы получить доступ к OID таблице?

Ссылка

Да вроде нормальная таблица.
А по числовому OID удается получить значение поля?

Я бы что еще сделал:
1) Попробовал (сильно) другую версию snmp-net;
2) Попробовал почистить MIB от trap'ов и вообще от всего, не относящегося к искомой таблице. Посмотрел, заработало бы так (нет ли конфликтов каких).

Разобрались

После долгих и мучительных разбирательств, заработало. Нужно было сделать так

self.serviceTable = self.agent.Table(
            oidstr  = mib+"serviceTable",
	    indexes = [
		self.agent.Integer32()
	    ],
	    columns = [
		(1, self.agent.Integer32(), True),
		(2, self.agent.DisplayString(""), True),
		(3, self.agent.Integer32(), True),
		(4, self.agent.TimeTicks(), True)
	    ],            
	    extendable = True
        )
