Странное поведение Catalyst 3750G-12S

[sol]

Коллеги, увидел странную вещь, не знаю что и думать.

Есть стек из двух 3750G-12S. Куча оптических линков. Само собой на не родных транссиверах и

service unsupported-transceiver

errdisable recovery тоже включен по всем причинам и таймер тоже задан.

 

Коммутатор приземляет небольшую пачечку ip unnumbered.  Около 60 шт.

 

Теперь фабула:

Первый раз при ребуте стека, второй раз при флапе оптического интерфейса, в смысле физики, интерфейс поднимался штатно, а вот vlan интерфейсы, чьи виланы приходят из него в коммутатор оставались в состоянии down. Причём, не все, а некоторые.

Down + Up на интерфейсе исправляет ситуацию мгновенно.

 

В логах при этом ничего интересного нет.

Вот интерфейсы погасли и вместе с ними ушли в down vlan интерфейсы. Всё как и должно быть.

А вот интерфейс поднялись:

Хорошо видно, что поднялись не все vlan из тех, которые упали.

А вот пришёл я и выключил-включил интерфейсы.

Видно, что в этот раз поднялись все виланы.

 

Софт в стеке c3750-ipservicesk9-mz.122-55.SE11.bin

 

[fox_m]

Не уверен, что поможет, но попробуйте на сетке включить mac-persistent. Заставляет использовать старый ID стека при ребуте мастера. 

 

stack-mac persistent timer 0

 

и ребут нудно сделать после этого, насколько я помню.
