Доброго утра!
Принял хозяйство и начал приводить в порядок. Задача номер один развести по вланам и столкнулся с проблемой.
Существует стек Dell 6248 (3 switch), к нему подключены два HP2910-48G(А2),связанные между собой оптикой.
Подключение
HP Aggrregation Group 1
1/g46(Dell)- P45(HP)
2/g46(Dell)-P46(HP)
3/g46(Dell)-P47(HP)
HP Aggrregation Group 2
1/g47(Dell)- P45(HP)
2/g47(Dell)-P46(HP)
3/g47(Dell)-P47(HP)
По типу кольцо получается, по схеме видно, прилагается.
Management HP уже нет, его не стало до меня.
STP включен.
Ping не стабилен, потери в среднем 50%. И не только с HP, но и с серверов и машин в той же подсети. Я не могу понять почему?
Кабеля целые, железо тоже!
Куда смотреть?
?
PS Прошу прощения конфиги немного кривые, в процессе разбора подписывания, для наглядности и настройки, и достались в таком состоянии. Существуют еще подсети которые живут сами собой для взаимосвязи специфических железок. Просто прописаны адрес с масками и как то они работают. И Их увы трогать нельзя.
Конфиги прилагаю. Прошу не пинать процесс на рабочей схеме уронить НЕЛЬЗЯ!

Но форуме Dell-a есть конфиги портов настроены Trunk-Trunk, реале сейчас General(dell)-Trunk(HP) в принципе ничего критичного не вижу.
Еще добавлена строка
spanning-tree portfas
Иногда включают Port Fast
Что посоветуете???
Куда смотреть куда копать!!!?
