Добрый день,

 

Возник вопрос поддерживает ли cat65 LACP линк агрегацию меж несколькими одинаковыми моделями lane cards?

 

Спасибо за ответ!

да.

 

Делается так же как и обычный лацп.

 

а с разными? имеется ввиду с одинаковой link speed, но разным phys media, аля 1GbE copper и spf?

 

Честно говоря не пробовал. Но не вижу причин почему нет.

На этой недели могу воткнуть-проверить.

Не получится. Должен быть 1 type

 

хмм надо проверить, а с чем это связано? я например никаких причин не вижу чтоб лацп не работал.

SUP32 - если вы помните там 8 SFP портов, 9й - медный.

Переделал на активный SUP, сделал no shut и порт-ченнелу и физическим портам (воткнуть правда некуда)... ничего не ругалось.

 

Физически порты некуда воткнуть, свободного оптического кабелька нет под рукой.

вопрос именно о cross lane card LAG, на портах одной lane card или на самом супервизоре все работает :)

В общем: etherchannel работает на портах с любых карт с одинаковыми параметрами: размером буферов и очередями QOS

пример : Etherchannel из портов с активного и hot sup

пример : Etherchannel из портов 6416 в разных слотах

 

Ранее не работало, если размер буферов на картах различался (пример - попытка обьединения портов с 6416 и 6516а)

Но в последних IOS вроде заработал etherchannel между портами разных карт (sup32 и 6416), но не подтвержу.

Ну и cross точно так же работает. Вот на разных карточках проверить не могу ибо у меня все одинаковые.
