1.华为交换机手工/LACP模式链路聚合配置
1.1配置手工模式链路聚合(默认模式)
如下,将华为交换机的GigabitEthernet 1/0/1到GigabitEthernet 1/0/3三个物理接口捆绑成一个逻辑接口(Eth-Trunk 1),并设置该逻辑接口为Trunk类型,允许VLAN 10和VLAN 20的数据通过。这样的配置在网络中常用于提高带宽利用率、实现负载均衡和增强网络可靠性。
[HUAWEI] interface eth-trunk 1 # 进入Eth-Trunk 1接口配置模式
[HUAWEI-Eth-Trunk1] trunkport gigabitethernet 1/0/1 to 1/0/3 # 添加成员接口到Eth-Trunk 1
[HUAWEI-Eth-Trunk1] port link-type trunk # 设置端口类型为Trunk
[HUAWEI-Eth-Trunk1] port trunk allow-pass vlan 10 20 # 配置允许通过的VLAN
[HUAWEI-Eth-Trunk1] quit
1.2配置LACP模式的链路聚合
LACP(链路聚合控制协议),它是一种用于在以太网链路上实现链路聚合的协议,它允许交换机之间通过LACP协议报文协商聚合参数,从而确保链路聚合的正确性和有效性。通过添加成员接口,这些接口将共同工作,实现带宽的聚合和负载的分担。
[HUAWEI] interface eth-trunk 1 # 进入Eth-Trunk 1接口配置模式
[HUAWEI-Eth-Trunk1] mode lacp # 设置Eth-Trunk的负载分担模式为LACP
[HUAWEI-Eth-Trunk1] trunkport gigabitethernet 1/0/1 to 1/0/3 # 添加成员接口到Eth-Trunk 1
[HUAWEI-Eth-Trunk1] port link-type trunk # 设置端口类型为Trunk
[HUAWEI-Eth-Trunk1] port trunk allow-pass vlan 10 20 # 配置允许通过的VLAN 10和VLAN 20
[HUAWEI-Eth-Trunk1] quit
2.H3C交换机二层静态聚合/动态聚合配置
在H3C网络设备中,配置链路聚合(也称为端口聚合或端口捆绑)时,通常会使用bridge-aggregation接口来创建一个聚合组。需要注意的是,H3C设备中bridge-aggregation接口的具体名称和配置方式可能会根据设备的型号和操作系统版本有所不同,下面仅为示例。
2.1二层静态聚合配置举例
# 创建二层聚合接口1
[H3C] interface bridge-aggregation 1
[H3C-Bridge-Aggregation1] quit
# 分别将端口GigabitEthernet1/0/1至GigabitEthernet1/0/3加入到聚合组1中
[H3C] interface gigabitethernet 1/0/1 # 进入GigabitEthernet 1/0/1接口配置模式
[H3C-GigabitEthernet1/0/1] port link-aggregation group 1 # 将GigabitEthernet 1/0/1接口添加到链路聚合组1
[H3C-GigabitEthernet1/0/1] quit
[H3C] interface gigabitethernet 1/0/2
[H3C-GigabitEthernet1/0/2] port link-aggregation group 1
[H3C-GigabitEthernet1/0/2] quit
[H3C] interface gigabitethernet 1/0/3
[H3C-GigabitEthernet1/0/3] port link-aggregation group 1
[H3C-GigabitEthernet1/0/3] quit
# 配置二层聚合接口1为Trunk端口,并允许VLAN 10和20的报文通过
[H3C] interface bridge-aggregation 1
[H3C-Bridge-Aggregation1] port link-type trunk
[H3C-Bridge-Aggregation1] port trunk permit vlan 10 20
[H3C-Bridge-Aggregation1] quit
2.2二层动态聚合配置
在动态模式下,链路聚合通常依赖于某种链路聚合控制协议(如LACP)来自动发现和配置聚合组成员。这意味着,当物理接口配置为加入聚合组并启用LACP时,它们会自动协商并成为聚合组的一部分,而无需手动配置每个接口。
# 创建二层聚合接口1,并配置该接口为动态聚合模式
[H3C] interface bridge-aggregation 1 # 进入bridge-aggregation接口配置模式
[H3C-Bridge-Aggregation1] link-aggregation mode dynamic # 设置链路聚合模式为动态
[H3C-Bridge-Aggregation1] quit
# 分别将端口GigabitEthernet1/0/1至GigabitEthernet1/0/3加入到聚合组1中
[H3C] interface gigabitethernet 1/0/1 # 进入GigabitEthernet 1/0/1接口配置模式
[H3C-GigabitEthernet1/0/1] port link-aggregation group 1 # 将GigabitEthernet 1/0/1接口添加到链路聚合组1
[H3C-GigabitEthernet1/0/1] quit
[H3C] interface gigabitethernet 1/0/2
[H3C-GigabitEthernet1/0/2] port link-aggregation group 1
[H3C-GigabitEthernet1/0/2] quit
[H3C] interface gigabitethernet 1/0/3
[H3C-GigabitEthernet1/0/3] port link-aggregation group 1
[H3C-GigabitEthernet1/0/3] quit
# 配置二层聚合接口1为Trunk端口,并允许VLAN 10和20的报文通过
[H3C] interface bridge-aggregation 1
[H3C-Bridge-Aggregation1] port link-type trunk
[H3C-Bridge-Aggregation1] port trunk permit vlan 10 20
[H3C-Bridge-Aggregation1] quit
3.锐捷交换机配置静态/动态模式链路聚合
同样,锐捷网络交换机的链路聚合(也称为端口聚合或端口捆绑)是一种高级网络功能,旨在通过将多个物理端口捆绑成一个逻辑端口(Aggregate Port,简称AP)来提供更高的带宽、增加冗余和提高网络的可靠性。
