华为ce12800交换机m-lag（V-STP模式）配置举例

配置## 标题思路

采用如下的思路配置M-LAG双归接入IP网络：

1.在Switch上配置上行接口绑定在一个Eth-Trunk中。

2.分别在SwitchA和SwitchB上配置V-STP、DFS Group、peer-link和M-LAG接口。

3.分别在SwitchA和SwitchB上配置LACP M-LAG的系统优先级、系统ID。

4.分别在SwitchA和SwitchB上配置VLANIF接口IP地址和MAC地址，作为接入设备的双活网关。

5.分别在SwitchA、SwitchB和SwitchC上配置OSPF功能，保证三层互通。

6.分别在SwitchA和SwitchB上配置Monitor Link关联上行接口和下行接口，避免因上行链路故障导致用户侧流量无法转发而丢弃。

在V-STP场景下，为防止接口因生成树协议计算结果被阻塞，可以通过配置主接口实现三层互通或者去使能IP网络侧的生成树协议。

配置Switch。

[*SwitchC-10GE1/0/1] ip address 10.3.1.2 24

[*SwitchC-10GE1/0/1] quit

[*SwitchC] interface 10ge 1/0/2

[*SwitchC-10GE1/0/2] undo portswitch

[*SwitchC-10GE1/0/2] ip address 10.4.1.2 24

[*SwitchC-ospf-1-area-0.0.0.0] quit

[*SwitchC-ospf-1] quit

6.分别在SwitchA和SwitchB上配置Monitor Link关联上行接口和下行接口

配置SwitchA。[~SwitchA] monitor-link group 1

[*SwitchA-mtlk-group1] port 10ge 1/0/1 uplink

[*SwitchA-mtlk-group1] port eth-trunk 10 downlink 1

[*SwitchA-mtlk-group1] quit

[*SwitchA] commit

配置SwitchB。[~SwitchB] monitor-link group 1

[*SwitchB-mtlk-group1] port 10ge 1/0/1 uplink

[*SwitchB-mtlk-group1] port eth-trunk 10 downlink 1

[*SwitchB-mtlk-group1] quit

[*SwitchB] commit

结果查看

查看DFS Group编号为1的M-LAG信息。

[~SwitchA] display dfs-group 1 m-lag

             : Local node

Heart beat state : OK

Node 1 *

Dfs-Group ID : 1

Priority : 150

Address : ip address 10.1.1.1

State : Master

Causation : -

System ID : 0025-9e95-7c31

SysName : SwitchA

Version : V100R006C00

Device Type : CE12800

Node 2

Dfs-Group ID : 1

Priority : 120

Address : ip address 10.1.1.2

State : Backup

Causation : -

System ID : 0025-9e95-7c11

SysName : SwitchB

Version : V100R006C00

Device Type : CE12800

查看SwitchA上的M-LAG信息。

[~SwitchA] display dfs-group 1 node 1 m-lag brief

- Local node

M-Lag ID Interface Port State Status

1 Eth-Trunk 10 Up active(*)-active

查看SwitchB上的M-LAG信息。

[~SwitchA] display dfs-group 1 node 2 m-lag brief

- Local node

M-Lag ID Interface Port State Status

1 Eth-Trunk 10 Up active-active(*)

通过以上显示信息可以看到，"Heart beat state"的状态是"OK"，表明心跳状态正常；SwitchA作为Node 1，优先级为150，"State"的状态是"Master"；SwitchB作为Node 2，优先级为120，"State"的状态是"Backup"。同时"Causation"的状态是"-"，Node 1的"Port State"状态为"Up"，Node 2的"Port State"状态为"Up"，且Node 1和Node 2的M-LAG状态均为"active"，表明M-LAG的配置正确。
