25.3.3. Сопоставление имен сетевых устройств каналам
Параметр
DEVICE= в файле ifcfg не содержит соответствия имен сетевых устройств и подканалов; они определены в файле правил /etc/udev/rules.d/70-persistent-net.rules.
При настройке нового сетевого устройства в System z новое правило будет автоматически добавлено в этот файл и выделено следующее незанятое имя устройства. Переменные
NAME= позволяют изменить автоматически присвоенные значения.
Пример файла
/etc/udev/rules.d/70-persistent-net.rules:
# This file was automatically generated by the /lib/udev/write_net_rules
# program run by the persistent-net-generator.rules rules file.
#
# You can modify it,as long as you keep each rule on a single line.
