    Столкнулся с интересной проблемой:

    В логах Cisco Catalyst вижу постоянные запросы от сервера NetXMS по SNMPv3
    При этом в самом netxms везде настроен SNMPv2. Других приложений/сервисов на хосте нет.

      Насколько постоянные? Во время configuration poll сервер может перебирать разные версии протоколов.

        Примерно так. В моем случае этл 90% сообщений в логе. Можно как-то отключить "перебор" версий протокола? Для ноды явным образом настроен SNMPv2.

          На интерфейсе сколько IP Если несколько выбери ближайщий по пути следования к серверу.

            В качестве "target" используется loopback коммутатора. IP адресов на нем как у дурака махорки, но их использование не совсем подходит ( интерфейс могут отключить, например руками или из-за аварии или может поменяется маршрутизация и тогда ближайший перестанет ближайшим )

            Чесно говоря не совсем понимаю каким образом это решит проблему

              Похоже на configuration poll. Перепроверю логику работы - в теории сначала должна пробоваться текущая версия протокола.
