Добрый день !

Дано:

1. Коммутатор PoE Cisco SG300-28MP (SW version 1.4.0.88 (софт последний));

2. Грозозащита PoE Nag-1.1P;

3. IP камеры Beward, Tantos.

Схема:

Коммутатор --> в него воткнута грозозащита --> в грозозащиту воткнута IP камера. Грозозащита заземлена, коммутатор заземлён, стойка телекоммуникационная заземлена, всё заземлёно от одной земли.

Проблема:

В вышеуказанной схеме начинается кратковременное дёрганье портов с какой-то периодичностью, см.ниже (для примера показано дёрганье одного порта (всего их девять)):

24-Oct-2014 14:42:57 %LINK-W-Down: gi18, aggregated (1)

24-Oct-2014 14:42:59 %LINK-I-Up: gi18, aggregated (1)

24-Oct-2014 14:46:11 %LINK-W-Down: gi18

24-Oct-2014 14:46:13 %LINK-I-Up: gi18

24-Oct-2014 14:49:53 %LINK-W-Down: gi18, aggregated (2)

 

Примечание. Картинка с камеры в этот момент не прерывается. Логи быстро переполняются этой требухой. Без грозозащиты порты не дёргаются.

Просьба помочь разобраться с этой проблемой.
