Здравейте,
имам 20 компютъра, вързани в един суич, които трябва да се свързват постоянно с един LTSP сървър с максимално допустима скорост.
Суичът е Mikrotik CSS326-24G-2S+RM - 24 гигабитови порта и 2 SFP +
На сървъра сложих Supermicro AOC-STGN-i1S, което е с чип  Intel 82599ES - 1 SFP + порт
Сървърът е с Ubuntu 12.04
И системата работи, но не съвсем.
Около 10 пъти на ден мрежовата връзка се разпада за около секунда-две
Код:
Sep  8 08:54:05 LtspServer kernel: [832875.459449] ixgbe 0000:01:00.0 eth2: NIC Link is Down
Sep  8 08:54:07 LtspServer kernel: [832877.460694] ixgbe 0000:01:00.0 eth2: NIC Link is Up 10 Gbps, Flow Control: TX
Разстоянието между суича и сървъра е 20 метра и респективно не се продават готови SFP-та със заработен кабел и се чудя дали това може да е проблемът. Ползвам SFP + с оптични кабели.
На някакъв форум прочетох, че трябвало да се ползва специален кабел с   Intel 82599ES, но дали е вярно - не знам. Готовите кабели са 3 или 5 метра. Тъй или иначе ще ми е трудно да преместя микротика по-близо до сървъра.
Някой ако е имал подобен проблем, моля да сподели как го е решил.

Първо какви са ти SFP модулите и второ - какво казват микротик логовете. Защото аз имам постоянно проблеми с микротик и сфп модули, които не са техни.

Няма грешки на микротика.
А sfp тата не ги знам какви какъв модел са, но са означени като SFP+ short range

В ето тази тема https://communities.intel.com/thread/103283 казват, че зависи от кабела и sfp-тата.
Мама му стара, не ми се опъват 20 кабела на 50 метра, че да приближа микротика.

В посочената тема пише, че проблема се дължи на шум от reference clock -а  --> https://communities.intel.com/message/409039#409039

А не може ли Mikroтik-а да отиде по-близо до комповете ?

може, ама трябва да пусна нови кабели от компютрите до микротика. Сегашните са по 20 метра, трябва да ги махна и да сложа нови по 40 примерно, което си е играчка.
Окачени тавани, кабелни скари - грозна картина

А това, че проблемът е reference clock, не знам какво мога да направя. Какво е reference clock - нещо в sfp модула ли?

Изхвърли микротика, и бягай далече от него!
Това е съвсем сериозно!

Онази тема според мен не се вписва точно при теб.
По скоро е свързана с фирма(компания), която разработва мрежов контролер на базата на чипа 82599, очевидно са имали проблем с linkstate при 10 Gbit,
Накрая са установили, че проблема е създаден заради използването на некачествен осцилатор за reference clock в мрежоввия им контролер.

Опитай да промениш нещо в постановката при теб: оптични пач корди, SFP трансивъри...

Re: проблем с 10 Gb/s мрежов адаптер
« Отговор #10 -: Сеп 09, 2017, 21:33 »
Ако имаш познати техници в някой интернет доставчик, помоли ги да ти замерят влакната с power meter. Първо се мери, ако има проблеми се чисти и после пак се мери. Процедурата се повтаря и от двата края. Когато влакното се включва в SFP модула, трябва да се внимава върха да не опре никъде, иначе множе да се зацапа и започват проблемите.

В наще среди не съм чувал, някой да използва mikrotik като суич. Вече има втора ръка Cisco на достъпна цена с 10Gb модули.

Точно за това искам тази информация от отгоре - без да се викат техници да се проверят нещата. Това са важните параматри:
Код:
        Optical diagnostics support               : Yes
        Laser bias current                        : 24.984 mA
        Laser output power                        : 0.5650 mW / -2.48 dBm
        Receiver signal average optical power     : 0.4670 mW / -3.31 dBm
        Module temperature                        : 48.80 degrees C / 119.83 degrees F
        Module voltage                            : 3.2669 V
Същата информация е достъпна и от микротика. Като се покажат и двете тук ще се види дали има оптичен проблем.

Благодаря за отговорите.
Точно това не ми го дава

Код:
ethtool -m eth2
ethtool: bad command line argument(s)
For more information run ethtool -h

Иначе разликите с твоята карта са

BRADATA - Advertised pause frame use: Symmetric
AZ - Advertised pause frame use: No

Код:
ethtool -a eth2
Pause parameters for eth2:
Autonegotiate: off
RX: off
TX: on

Спрял съм flow контрола, че микротика даваше грешки.
Но понеже проблемът се проявява десетина пъти на ден, предполагам, че става дума за някаква хардуерна глупост. Освен това се случва и в извънработно време, когато компютрите са изключени, така че не е от претоварване.

Пробвай с друга лан карта. Щом във форума на интел казват, че проблема се дължал на 'лош' reference clocк и проблема се оправил след смяна на clock device-a (некакво чипче) покрай 82599EN значи проблема много вероятно да е точно това.

Цитат
Then, I measured a reference clock and found the cause for this issue....... So I replaced clock device near a 82599EN .... And I confirmed that the link up status is kept on 10Gbps.

Такива проблеми от вида ту го има, ту го няма и то от време на време... са много гадни щото много трудно се хващат. Нещо работи на границата на спецификацията. От друга страна ако има такъв 'рядък' проблем проиводителя на хардуера, колкото и да е марков, никога няма да си признае....Ще разправят за несъвместимости и т.н.

Тъй че ако можеш пробвай с друг хардуер.

Аз имах доста проблеми с микротишките CCR неща докато не си купих микротишки SFP-та. В интерес на истината не съм тествал SFP+ връзки, но факта, че са капризни на гигабитови SFP-та е показателен. Дори оригинални CISCO SFP-та водят до забивания и рестарти.
Имай го предвид.
Пробвай също така да видиш DDM информацията на SFP-то под линукс. Важно е. А ако няма такава функционалност - по-добре го смени. Аз ползвам HiTech от КСТ.
