Ковырялись в конфигурации некоего свитча, имеющего публичный IP адрес, и на всякий случай, чтоб не заблокировать самих себя, отключили access list, который не дает соединяться с железкой кому попало. В логи тут же полезло:

В результате работа встала, все с интересом смотрели в логи. Потом надоело, конечно, ибо тупизна несусветная, и включили access list обратно.
