求smart link配置步骤

您好，请知：

以下是smart-link的配置举例：

1.6  Smart Link典型配置举例

1.6.1  单Smart Link组配置举例

1. 组网需求

·     在图1-2所示的组网中，Device C和Device D为Smart Link设备，Device A、Device B和Device E为相关设备。Device C和Device D上VLAN 1～30的流量分别双上行到Device A。

·     通过配置，在Device C和Device D上分别实现双上行链路的灵活备份。

4. 验证配置

通过使用display smart-link group命令可以查看设备上Smart Link组的信息：

# 显示Device C上Smart Link组的信息。

[DeviceC] display smart-link group 1

Smart link group 1 information:

  Device ID       : 000f-e23d-5af0

  Preemption mode : None

  Preemption delay: 1(s)

  Control VLAN    : 10

  Protected VLAN  : Reference Instance 1

  Member                  Role      State   Flush-count     Last-flush-time

  -----------------------------------------------------------------------------

  GE1/0/1                 PRIMARY   ACTIVE  5               16:45:20 2012/04/21

  GE1/0/2                 SECONDARY STANDBY 1               16:37:20 2012/04/21

通过使用display smart-link flush命令可以查看设备上收到的Flush报文信息：

# 显示Device B上收到的Flush报文信息。

[DeviceB] display smart-link flush

 Received flush packets                             : 5

 Receiving interface of the last flush packet       : GigabitEthernet1/0/3

 Receiving time of the last flush packet            : 16:50:21 2012/04/21

 Device ID of the last flush packet                 : 000f-e23d-5af0

 Control VLAN of the last flush packet              : 10
