AR2240端口协商

发布时间:  2017-05-15 浏览次数:  79 下载次数:  0
问题描述

1、版本信息:V200R007C00SPC500+V200R007SPH009

2、网络拓扑:不涉及。

3、配置脚本:不涉及。

4、故障现象:AR2240C的光电复用口使用电口和传输设备对接,ospf邻居建立成功,网络正常;一会儿时间网络中断,查看ospf的邻居状态就变成Init状态。

处理过程

1、将光电复用口强制成电口,在做端口强制;

[AR2240C-01-GigabitEthernet0/0/5]combo-port copper

[AR2240C-01-GigabitEthernet0/0/5]und negotiation auto

根因

1、端口协商成半双工模式;导致ospf邻居建立不起来。

解决方案

1、将光电复用口强制成电口,在做端口强制;

[AR2240C-01-GigabitEthernet0/0/5]combo-port copper

[AR2240C-01-GigabitEthernet0/0/5]und negotiation auto

2、强制后的状态:
[NXXS-YCFGS-AR2240C-01-GigabitEthernet0/0/5]dis int g 0/0/5
GigabitEthernet0/0/5 current state : UP
Line protocol current state : DOWN
