Cisco 6506 проблема с port-channel

Заменили 3750 на 6506 sup32, почемуто в port-ch1 скорость не поднимается выше 1 gbit/s, там 4 линка, с другой стороны dlink 3100-24ts. До замены циски всё работало. Просветлился по port-channel, ничего нового не узнал и проблему не могу решить. Есть идеи?

трафик льется равномерно по портам ?

 

port-channel load-balance src-dst-ip стоит ?

 

что за карта линейная ? разнесите порты. 1 9 17 24

port-channel load-balance src-dst-ip не стоял, поставил - не помогло.

Разнёс по портам, эффект есть. Сейчас не 1 gbit/s, а 1.2 gbit/s, но опять уперлось.

Трафик льется равномерно по всем четырем

zhenya Спасибо добрый человек за указанное направление. За полчаса до часа пик всё сделали.

 

нашёл эту доку

Проблема в модулях WS-X6148-GE-TX они не прокачивают на порт шанелях больше гига

Взяв 3 медиаконвертера, 6 sfp и 1 медный патчкорд я подключился к модулю

WS-SUP32-GE-3B

 

И скорость на портшанеле попёрла.

Ну реально - вынос мозга.

 

Подскажите что купить вместо WS-X6148-GE-TX ? Чтобы не было проблем с превышением объёма подписки с etherchannel.

WS-X6516-GE-TX не имеет таких ограничений(1 gbit/s на etherchannel), но в ней мало портов. Более многопортовые адекватные карты для sup 32 подсказать не могу, ибо сами пока не нашли

Я вот думаю это проблема только с etherchannel или весь модуль WS-X6148-GE-TX больше гига не прокачивает?

 

Во время обнаружения проблемы у меня было 2 portchannel и у каждого скорость была как раз по половинке 500мбит/с .

Модуль больше прокачает. Проблемы с etherchannel на этом модуле.

The WS-X6148-GE-TX and WS-X6148V-GE-TX switching modules do not support more than

1 Gbps of traffic per EtherChannel.

Что купить - делайте выводы из доки ниже :)

Link to cisco doc

Удачи :)
