几周前我堆叠了两台 3750G Cisco 交换机,一切正常。但是,昨天我还安装了第二条堆叠电缆,以进行全面优化。但是,它似乎没有注册。
Cisco3750#sh switch stack-ports
Switch # Port 1 Port 2
-------- ------ ------
1 Ok Down
2 Ok Down
我谷歌了一下,找到了这两个。这是启用第二条堆叠电缆的正确方法吗?
switch 1 stack port 2 enable
switch 2 stack port 2 enable
下午 4 点编辑:另一次搜索显示要交叉电缆(十字交叉)。不确定这里发生了什么,但上述启用命令没有奏效。
Each 3750 switch’s back has two stack ports 1 and 2.
Suppose you want to connect two switches with two stack cables:
1st switch port 1 connects to 2nd switch port 2.
1st switch port 2 connects to 1st switch port 1.
The stack cables will be crossed.
更新 #2 晚上 10:30
关机,按建议将堆叠电缆绕成环路,然后开机。显示环路(端口 1 到端口 2,反之亦然),但第二根电缆仍未注册。
