我有一台 Debian Jessie 服务器，该服务器带有两个板载 1Gbps NIC 的 Intel i350，我想使用 802.3ad 协议将其桥接到我的 HP 1920G 48 端口管理型交换机。
这是我正在运行的内核
~ % uname -a
Linux ltsp 4.9.0-0.bpo.3-amd64 #1 SMP Debian 4.9.30-2+deb9u5~bpo8+1 (2017-09-28) x86_64 GNU/Linux
我已经为 802.3ad 设置了交换机的 LACP 端口 3 和 4，但是当我尝试连接我的绑定网络时，它会抱怨“端口配置不适合连接”。
在我的 /etc/modules 中我有
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
loop
vhost_net
bonding
我已经安装了 ifenslave
sudo apt install ifenslave-2.6
这是 /etc/network/interfaces 文件
auto lo
iface lo inet loopback
# bond0 is the bonding NIC and can be used like any other normal NIC.
# bond0 is configured using static network information.
auto bond0
iface bond0 inet static
address 192.168.200.5
gateway 192.168.200.1
netmask 255.255.255.0
dns-nameservers 8.8.8.8
dns-search lan
# Use IEEE 802.3ad LACP bonding protocol
bond-mode 4
bond-miimon 100
bond-slaves none
#eth2 is manually configured, and slave to the “bond0” bonded NIC
allow_hotplug eth2
auto eth2
iface eth2 inet manual
bond-master bond0
bond-primary eth2
#eth3 ditto, thus creating a 2-link bond.
allow_hotplug eth3
auto eth3
iface eth3 inet manual
bond-master bond0
输出结果

这不管用。我无法在 192.168.200.5 上 ping 这台机器。我这里漏掉了什么？
更新 2018/08/23
尝试在模块文件中设置粘合属性。
编辑 /etc/modules

GigabitEthernet1/0/3 和 GigabitEthernet1/0/4 是我要绑定的端口。您可以看到它们是链路聚合组的一部分。
更新：查看日志文件
要检查日志文件，我必须通过 Web 后端“设备 -> 系统日志”执行此操作，并在我的测试粘合机上重新启动网络后，我得到了以下四行；
Aug 28 10:59:06:287 2018 IFNET Error LINK_UPDOWN GigabitEthernet1/0/4 link status is UP.
Aug 28 10:58:56:005 2018 IFNET Error LINK_UPDOWN GigabitEthernet1/0/3 link status is UP.
Aug 28 10:58:43:066 2018 IFNET Error LINK_UPDOWN GigabitEthernet1/0/3 link status is DOWN.
Aug 28 10:58:33:338 2018 IFNET Error LINK_UPDOWN GigabitEthernet1/0/4 link status is DOWN.
答案1
您的各个接口和Bridge-Aggregation1接口的配置彼此之间有足够的差异，从而阻止它们成为链路聚合的一部分。您的配置应如下所示：
interface Bridge-Aggregation1
port link-type trunk
port trunk permit vlan 1
link-aggregation mode dynamic
