Есть сервер, с ОС Centos 6.4. У провайдера иногда пропадает интернет, и сервер не обновляет параметры сети, не получает IP и т.д, и по этому его приходится постоянно перезагружать. Может есть какой-нибудь скрипт, который будет при появлении интернета, обновлять параметры. Так как не обновляется сеть при повторном появлении интернета

Имеются 2 сетевые карты, объединённые в BOND-инг (4) + имеется коммутатор

Коммутатор стоит в режиме:

Link Aggregation Algorithm = IP-Destination

На нём есть доступные алгоритмы:

На коммутаторе есть алгоритмы:
mac_source
mac_destination
mac_source_dest
ip_source
ip_destination
ip_source_dest
l4_src_port
l4_dest_port
l4_src_dest_port

Каждый день, примерно в 6 утра отваливается сеть! Причём до 6 утра всё нормально!
