为什么思科端口未连接但另一端出现

为什么思科端口未连接但另一端出现

我的 Cisco Catalyst 3850 上有一个 SFP 模块,它连接到另一个设备,另一个设备(供应商设备)上的端口已启动,但我的接口仍处于关闭状态。DOM 信息显示接收和传输 pegel,如果我在该接口上执行关闭命令,另一端将关闭。

这是该端口的配置:

interface GigabitEthernet1/0/8
 description port1
 no switchport
 ip address 10.1.1.80 255.255.255.254
end

但端口仍然处于关闭状态:

sh int gi1/0/8 status

Port      Name               Status       Vlan       Duplex  Speed Type 
Gi1/0/8   port1   notconnect   routed       full   1000 1000BaseLX SFP

在收发器详细信息页面上,一切正常:

#sh int gi1/0/8 transceiver detail

我更换了 SFP 模块,但情况仍然相同,更换端口也一样。我该如何解决此问题?

对我来说,有点奇怪的是,另一台设备上的端口已启动,但我的设备仍然处于关闭状态。

供应商喜欢禁用一切偶然情况。使用speed nonegotiate打开链接。
