Xpeed 320 / Странные пинги между ними.

[tentura]

Вот как интересно ходят пинги после замены PairGain 300S на Xpeed 320.

Дальность небольшая, протокол 1490 Bridged Ethernet LMI on

 

пакеты вобщем-то доходят все, но некоторые с задержкой 20-60 секунд!

 

Может, это фича а не баг и кто-то уже встречался?

Бывало, лечили.

Может софт надо свежий залить,

но по моему - надо включить в порт, который залочен на 10 мегабит.

Куча железа не может нормально договариваться с китайскими коммутаторами дешевыми.

В общем, спрошу на днях точно.

[Sirco]

Ну не знаю что ты там будеш спрашивать - у меня мнение что данный пакет пропал

и модемы самостоятельно его повторно переприняли - вот вся и лажа .

Почему это не воспринялось как ошибка , комп не сказал что он потерялся - да потому что он (комп) не давал запроса на повторную передачу ...

Рекомендация - проверь канал на отсутствие тресков , шумов ,...

[Sirco]

Нагу

И нечего на Интел бочку котить - в хабе который стоит в Xpeed 320 стоит микросхемка

Левел Оне - дочерняя компания Интел ;-) А ты китайцы ;-)

[tentura]

С одной стороны свитч от Bay (нормальный), с другой фря с Intel Ether Express.

 

Вопрос в том - где этот пакет проживает свои 20-60 секунд....

[Nag]

tentura,

О. Так зажми порты на 10 мегабит, поиграй с дуплексами.

Может кажется несвязанным - но именно эти меры однажды помогли (если не мой склероз).

[tentura]

только что сделали. непомогло.

[Sirco]

Вопрос в том - где этот пакет проживает свои 20-60 секунд....

Ну так я ж обяснял :

Пакет потерялся между модемами и они на канальном уровне решили

его перепринять - вот он и возникает через 20 - 60 сек .

 

Может и не так - но мне так кажеться ;-)
