Cisco -- залипает PPP

Дано:

1. организовывается корпоративный VPN (MPLS).

2. В центральном офисе и в филиале установлены Cisco 2621XM.

3. Циски подключены к PE провайдера оборудованием последней мили.

4. между CE и PE бегает PPP.

5. Маршрутизация сделана экспортом через BGP в автономку провайдера.

 

Жалоба: Примерно раз в 6 часов отваливается канал (перестает ходить пинг) между CE и PE головного офиса.

 

Симптомы:

WAN-serial в UP, Line protocol тоже в UP. не ходят именно данные.

В логинг буфер пишется, что сериал падает, потом поднимается (падает по разным причинам -- 10 SES, LOS, LOF)

лечится либо звонком провайдеру, либо encap HDLC ... encap PPP на интерфейсе (т.е. передергиванием PPP).

wan-модуль меняли, не помогает.

ios меняли, не помогает.

ppp на hdlc меняли, не помогает.

у провайдера на оборудовании последней мили (miniSDH) в логах нет ни одной записи об ошибках.

 

вопрос: что это может быть? подскажите хотя бы направление, где копать.

sh contr e1 что говорит?

sh int что говорит?

На обоих сторонах.

 

Думаю, прежде всего копать clock source на E1.

Не поможет - смотреть дальше.

Неужто нет здесь цискарей?

 

===

Остановлюсь поподробнее.

Вкратце, схема такая:

 

{VPN} === [PE] --- E1 --- [LM] === [LM] --- E1 --- [CE] --- {LAN}

 

PE -- Provider's Edge (10.100.77.1)

E1 -- поток Е1

LM -- Оборудование "последней мили" (какой-то mSDH Huawei), подключен по оптике.

CE -- Customer's Edge (C2621XM) (10.100.77.2)

 

Дальше рассказываю про CE.
