华为CE交换机：配置ERPS多实例

2026年 4月 7日 交换机 SE_YT

配置ERPS多实例

组网需求

在ERPS组网中，一个物理环上只能配置一个ERPS环，也只能指定一个阻塞点。当ERPS环处于完整状态时，阻塞端口会阻止所有的用户报文通过，这导致所有用户报文在ERPS环上只能通过一条路径传输，阻塞端口另一侧的链路空闲，造成了带宽浪费。

如图 ERPS单环多实例组网图所示，在DeviceA～DeviceD上配置两个ERPS实例，ERPS环1和ERPS环2，ERPS环1阻塞DeviceB的P1端口，ERPS环2阻塞DeviceA的P2端口，实现负载分担并提供链路备份。

本例中interface1、interface2分别代表100GE1/0/1、100GE1/0/2。

华为CE交换机：配置ERPS多实例

配置思路

采用如下的思路配置ERPS单环多实例：

  1. 配置加入ERPS环的所有端口类型为Trunk型。

  2. 创建ERPS环，并配置控制VLAN和保护实例。

  3. 将二层端口加入ERPS环并配置端口角色。

  4. 配置ERPS环的Guard Timer和WTR Timer定时器。

  5. 配置DeviceA～DeviceD二层转发功能。

操作步骤

  1. 配置加入ERPS环的所有端口类型为Trunk型。 

    # 配置DeviceA。DeviceB、DeviceC、DeviceD的配置与DeviceA类似，详见配置脚本。

    <HUAWEI> system-view
[~HUAWEI] sysname DeviceA
[~HUAWEI] commit
[~DeviceA] interface 100ge 1/0/1
[*DeviceA-100GE1/0/1] portswitch
[*DeviceA-100GE1/0/1] port link-type trunk
[*DeviceA-100GE1/0/1] quit
[*DeviceA] interface 100ge 1/0/2
[*DeviceA-100GE1/0/2] portswitch
[*DeviceA-100GE1/0/2] port link-type trunk
[*DeviceA-100GE1/0/2] quit
[*DeviceA-100GE1/0/2] commit

     

  2. 创建ERPS环1、ERPS环2并配置两个ERPS环的保护实例，配置ERPS环1的控制VLAN ID为10，ERPS环2的控制VLAN ID为20，ERPS环1传递VLAN100～VLAN200的数据报文，ERPS环2传递VLAN300～VLAN400的数据报文。 

    # 配置DeviceA。DeviceB、DeviceC、DeviceD的配置与DeviceA类似，详见配置脚本。

    [~DeviceA] erps ring 1
[*DeviceA-erps-ring1] control-vlan 10
[*DeviceA-erps-ring1] protected-instance 1
[*DeviceA-erps-ring1] quit
[*DeviceA] stp region-configuration
[*DeviceA-mst-region] instance 1 vlan 10 100 to 200
[*DeviceA-mst-region] quit
[*DeviceA] erps ring 2
[*DeviceA-erps-ring2] control-vlan 20
[*DeviceA-erps-ring2] protected-instance 2
[*DeviceA-erps-ring2] quit
[*DeviceA] stp region-configuration
[*DeviceA-mst-region] instance 2 vlan 20 300 to 400
[*DeviceA-mst-region] quit
[*DeviceA-mst-region] commit

     

  3. 将二层端口加入ERPS环并配置端口角色，分别将DeviceA的端口100GE1/0/1和DeviceB的端口100GE1/0/2配置为RPL owner。 

    # 配置DeviceA。

    [~DeviceA] interface 100ge 1/0/1
[*DeviceA-100GE1/0/1] stp disable
[*DeviceA-100GE1/0/1] erps ring 1
[*DeviceA-100GE1/0/1] erps ring 2 rpl owner
[*DeviceA-100GE1/0/1] quit
[*DeviceA] interface 100ge 1/0/2
[*DeviceA-100GE1/0/2] stp disable
[*DeviceA-100GE1/0/2] erps ring 1
[*DeviceA-100GE1/0/2] erps ring 2
[*DeviceA-100GE1/0/2] quit
[*DeviceA] commit
    # 配置DeviceB。

    [~DeviceB] interface 100ge 1/0/1
[*DeviceB-100GE1/0/1] stp disable
[*DeviceB-100GE1/0/1] erps ring 1
[*DeviceB-100GE1/0/1] erps ring 2
[*DeviceB-100GE1/0/1] quit
[*DeviceB] interface 100ge 1/0/2
[*DeviceB-100GE1/0/2] stp disable
[*DeviceB-100GE1/0/2] erps ring 1 rpl owner
[*DeviceB-100GE1/0/2] erps ring 2
[*DeviceB-100GE1/0/2] quit
[*DeviceB] commit

    # 配置DeviceC。DeviceD的配置与DeviceC类似，详见配置脚本。

    [~DeviceC] interface 100ge 1/0/1
[*DeviceC-100GE1/0/1] stp disable
[*DeviceC-100GE1/0/1] erps ring 1
[*DeviceC-100GE1/0/1] erps ring 2
[*DeviceC-100GE1/0/1] quit
[*DeviceC] interface 100ge 1/0/2
[*DeviceC-100GE1/0/2] stp disable
[*DeviceC-100GE1/0/2] erps ring 1
[*DeviceC-100GE1/0/2] erps ring 2
[*DeviceC-100GE1/0/2] quit
[*DeviceC] commit

     

  4. 配置ERPS环的Guard Timer和WTR Timer定时器。 

    # 配置DeviceA。DeviceB、DeviceC、DeviceD的配置与DeviceA类似，详见配置脚本。

    [~DeviceA] erps ring 1
[~DeviceA-erps-ring1] wtr-timer 6
[*DeviceA-erps-ring1] guard-timer 100
[*DeviceA-erps-ring1] quit
[*DeviceA] erps ring 2
[*DeviceA-erps-ring2] wtr-timer 6
[*DeviceA-erps-ring2] guard-timer 100
[*DeviceA-erps-ring2] quit
[*DeviceA] commit

     

  5. 配置DeviceA～DeviceD二层转发功能。 

    # 配置DeviceA。DeviceB、DeviceC、DeviceD的配置与DeviceA类似，详见配置脚本。

    [~DeviceA] vlan batch 100 to 200 300 to 400
[*DeviceA] interface 100ge 1/0/1
[*DeviceA-100GE1/0/1] undo port trunk allow-pass vlan 1
[*DeviceA-100GE1/0/1] port trunk allow-pass vlan 100 to 200 300 to 400
[*DeviceA-100GE1/0/1] quit
[*DeviceA] interface 100ge 1/0/2
[*DeviceA-100GE1/0/2] undo port trunk allow-pass vlan 1
[*DeviceA-100GE1/0/2] port trunk allow-pass vlan 100 to 200 300 to 400
[*DeviceA-100GE1/0/2] quit
[*DeviceA] commit

     

  6. 验证配置结果 

    # 在网络稳定后，在设备上执行display erps，查看设备加入的ERPS环的端口和环的概要信息。以DeviceB为例。
