Настройка Cisco оборудования - [56] :: В помощь системному администратору

JonJonson
1. пока инты не упали все отлично (ошибок нет) - когда упали к циске доступа нет!!!
2. все инты в авто.
3. модемы есть - но проблема решается, как указано, перезагрузкой циски и не троганием модемов!
alespopov
в прошивке может быть дело только если она сама посебе глючная (так сделана), но никаких подобных багов по ней в инете не нашел!
как было указано - менялось полностью железо!!! (прошивка перезаливалась само собой). Статистика памяти ровнейшая

ESX091
1. именно это и хочу выяснить!!! sla не перестает работать - как раз работает!!! и по логам как раз видно что его статус постоянно UP/DOWN на обоих провайдерских интерфейсах!!!
2. инты подключены независимо - один через модем прова, второй напрямую кабелем!
3. остаться на ночь нет возможности (в этом как раз проблема!) циска в др. городе за несколько сот км.
vlary
не о том!!! отсутствее local pbr в данном случае влияет только на построение тунелей!!! стат маршрутами ПРАВЕЛЬНО указано за каким провом какой конец тунеля искать!
