最佳答案
你提供的日志显示:端口 Twenty-FiveGigE1/1/10
(也显示为 WGE1/1/10
)频繁上下线、LACP 超时、聚合状态切换。以下是详尽的解析与排查建议。
以下是关键事件的时间序列:
时间顺序 | 日志事件 |
---|---|
✅ PHY Up | 接口物理层状态变为 up(连上) |
✅ Line protocol Up | 二层协议状态 up(链路通) |
❌ LACP Timeout | LACP 协议收不到对端 PDU,端口从聚合组中移除 |
❌ PHY Down | 接口物理层 down(断开) |
❌ Line protocol Down | 二层状态也 down |
🔁 重复上述过程 | 接口多次重复 up/down、加入/退出聚合组 |
类别 | 原因 | 说明 |
---|---|---|
🧩 物理问题 | 光模块或光纤故障 | 接触不良、弯折、插拔不牢导致 link flap(频繁上下) |
🔌 电源或设备问题 | 槽位电源不稳、板卡异常 | 会导致端口异常重置 |
🌐 配置不一致 | 聚合配置(LACP 模式、速度、双工)不一致 | LACP 协议异常,收不到 PDU |
⏱️ 收发延迟 | 对端设备未响应及时 | LACP 报文超时(默认超时是 3 秒) |
🔍 LLDP 邻居信息反复变化 | 表示设备间链路频繁变化 | 支持侧验证链路是否抖动 |
❌ 对端接口异常 | 对端接口配置错误、被 shutdown、或是 flap | 影响本端接口稳定性 |
检查光纤跳线是否插紧
更换光模块/跳线进行排查
使用命令查看收光功率是否异常:
display transceiver interface Twenty-FiveGigE1/1/10 verbose
检查是否有 low rx power、los(光丢失)、温度异常 等告警
本端:
display this interface Ten-GigabitEthernet1/1/10
display link-aggregation verbose
对端(如连接的是交换机 A):
display current-configuration interface Ten-GigabitEthernet1/0/27
⚠️ 检查聚合模式是否一致(dynamic/active/passive)
debugging link-aggregation event
debugging link-aggregation lacp
注意:调试期间请在业务低峰启用,建议短时间观察后关闭 undo debugging all
display cpu-usage
display health
display interface Ten-GigabitEthernet1/1/10
查看是否存在 CPU 占用异常、接口报错、CRC 错误、巨帧、输入错误等。
使用:
display version
并与 H3C 官网或官方 TAC 工程师确认是否当前版本存在 LACP 协议异常 bug 或兼容性问题。
操作 | 命令 |
---|---|
强制 LAG 接口为静态模式(绕过 LACP) | link-aggregation mode manual |
临时下线故障成员端口 | shutdown interface Twenty-FiveGigE1/1/10 |
限制 LACP 超时时间提升容错 | lacp timeout long (默认 fast) |
这类频繁的端口 flap、LACP 超时通常是 物理层或配置层问题,极少是软件 bug;
若为业务核心链路,建议临时先停用该 member port 保持聚合稳定;
后续建议对链路、模块、配置全面核查,必要时联系 H3C 开 case。
如你能提供:
对端设备型号和端口
当前 display current-configuration interface
和 display link-aggregation verbose
输出
(0)
可能光模块有问题
聚合组内参考端口接收对端的LACPDU超时
LAGG/6/LAGG_LACP_RECEIVE_TIMEOUT: -Slot=1; LACPDU reception timed out on member port WGE1/1/10 in aggregation group BAGG110.
