Сервер с CentOS 7, коммутатор D-Link DES 2810

Нужно сделать агрегацию каналов, с последующей нарезкой vlan-ов. Для этой цели в сервере стоит две одинаковый сетевые карточки и они подключены в свитч, который настроим позже.

Проверяем как увиделись карточки в системе:

# lspci | grep -i ether
04:00.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
04:01.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
04:02.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 10)
05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)

Проверяем есть ли модуль в системе:

# lsmod | grep bonding
bonding 152656 0

Создаем конф файл ifcfg-bond0:

# vi /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0
NAME=bond0
TYPE=Bond
BONDING_MASTER=yes
IPV6INIT=no
MTU=9000
ONBOOT=yes
USERCTL=no
NM_CONTROLLED=no
IPADDR=192.168.113.84

GATEWAY=192.168.113.1
DNS1=127.0.0.1

DNS3=8.8.8.8
DOMAIN=example.com
BOOTPROTO=none
BONDING_OPTS="mode=802.3ad xmit_hash_policy=layer2+3 lacp_rate=1 miimon=100"

Проверяем! Важно, что бы в секции в строке МАС адрес были не нули, так это будет означать, что обмен пакетами не происходит:

# cat /proc/net/bonding/bond0 | less
