2台华为交换机配置mlag

MLAG（Multi-Chassis Link Aggregation）是一种技术，可以在两个交换机之间创建逻辑链路聚合组，提供高可靠性和高可用性。下面是华为交换机配置MLAG的步骤：

1. 配置MLAG域和ID：在两个交换机上分别执行以下命令

[SwitchA] mlag
[SwitchA-mlag] domain mlag-domain
[SwitchA-mlag] cluster-id 1
[SwitchA-mlag] quit

[SwitchB] mlag
[SwitchB-mlag] domain mlag-domain
[SwitchB-mlag] cluster-id 1
[SwitchB-mlag] quit

2. 配置MLAG接口：在两个交换机上分别执行以下命令

[SwitchA] interface eth-trunk 1
[SwitchA-Eth-Trunk1] mlag 1
[SwitchA-Eth-Trunk1] quit

[SwitchB] interface eth-trunk 1
[SwitchB-Eth-Trunk1] mlag 1
[SwitchB-Eth-Trunk1] quit

3. 配置MLAG IP地址：在两个交换机上分别执行以下命令

[SwitchA] interface vlanif 1
[SwitchA-Vlanif1] ip address 192.168.1.1 24
[SwitchA-Vlanif1] mlag 1 peer-ip 192.168.1.2
[SwitchA-Vlanif1] quit

[SwitchB] interface vlanif 1
[SwitchB-Vlanif1] ip address 192.168.1.2 24
[SwitchB-Vlanif1] mlag 1 peer-ip 192.168.1.1
[SwitchB-Vlanif1] quit

4. 配置MLAG接口状态：在两个交换机上分别执行以下命令

[SwitchA] interface eth-trunk 1
[SwitchA-Eth-Trunk1] port link-type trunk
[SwitchA-Eth-Trunk1] port trunk allow-pass vlan 10
[SwitchA-Eth-Trunk1] mlag 1 peer-link
[SwitchA-Eth-Trunk1] quit

[SwitchB] interface eth-trunk 1
[SwitchB-Eth-Trunk1] port link-type trunk
[SwitchB-Eth-Trunk1] port trunk allow-pass vlan 10
[SwitchB-Eth-Trunk1] mlag 1 peer-link
[SwitchB-Eth-Trunk1] quit

5. 验证MLAG配置：在两个交换机上分别执行以下命令

[SwitchA] display mlag
[SwitchB] display mlag

以上步骤是华为交换机配置MLAG的基本步骤，具体配置可能会有所不同，需要根据实际情况进行调整。
