为Cisco 3850收到了一堆框,将用于构建高可用性切换环境的交换堆栈。

对于2960系列,有关于它的帖子:

思科催化剂WS-C3850-48T-S和组件(未填充)

思科 Catalyst WS-C3850-48T-S和盒子中的组件

思科催化剂WS-C3850-48T-S回来

思科催化剂WS-C3850-48T-S正面
思科 Catalyst 3850插入电源堆叠电缆和数据堆叠电缆

思科 Catalyst 3850 10G模块(C3850-NM-2-10G)

1.连接物理电源堆栈电缆和数据堆叠电缆:

确保将数据堆叠电缆插入正确的方向。机架中的其他设备可能会阻止您的视图,以查看是否已完全插入数据电缆。

2.连接只需一个电源线

4.验证堆栈电缆连接:
Switch#show switch stack-ports 

Switch#   Port1     Port2     
----------------------------
1         OK        OK        
2         OK        OK 

Switch#show switch stack-ring speed 

Stack Ring Speed        : 480G
Stack Ring Configuration: Full
Stack Ring Protocol     : StackWise




笔记:

  • 控制台端口:可以通过堆栈中的任何控制台端口访问活动控制台。
  • 堆叠成员优先级:用于堆构件A更高的优先级值将增加它当选有源开关和保持其堆栈构件数的概率。优先级值可以是1到15.默认优先级值为1.您可以使用show switch exec命令显示堆栈成员优先级值。
  • 有源开关选举:有源开关被选出或重选基于这些因素之一,在列出的顺序:
    • 当前是主动开关的开关。
    • 具有最高堆栈成员优先级值的开关。
    • 开关具有最短的启动时间。
    • 具有最低MAC地址的开关。
  • 思科建议将最高优先级值分配给您喜欢成为活动交换机的开关。这可确保如果发生重新选择,则将开关被重新选择为活动开关。
  • 您可以在交换机上使用ACTV LED,看看交换机是否是活动开关。
    • 离开
      开关不是主动开关。

      笔记     对于独立式开关,此LED已关闭。
      绿色的
      开关是有源开关。
      琥珀色
      主动开关选举期间出错。
      闪烁绿色
      交换机是数据堆栈的备用成员,如果当前主动开关发生故障,则假定有效职责。
