产生告警信息板卡BJR-PE-T9K001-NPB01 10.243.11.1
最初出现时间2022-02-09 17:01:53  
故障截止目前仍未消除。**luqiuwen** commented on *2022-02-11T09:54:28.646+0800*:
与现场人员交流并通过远程协助方式获取以下信息:
* 故障的范围仅限于BJR-PE单板卡其他板卡正常工作。
* 流量情况约3Gbps3Mpps, 平均报文长度约100字节。

* 负载平衡情况:单线程负载远远大于其他线程负载,该线程大量丢包:

* 在该线程上捕包发现全部为VRRP广播报文这些报文所有分流要素全部一致具有相同的源地址、目的地址被分流到同一线程上。

现推测运营商侧错误配置导致的VRRP报文在网络内广播这种情况超出了设备的处理能力导致丢包。
这种情况暂无较好的解决方案。可以考虑的处置方法有:
# 因该报文对业务无明显的影响可以考虑在交换板上配置源IP-目的IP地址的规则放行该报文。
# 建议业主协调运营商消除错误配置。

在BJR-PE的SMBIO的service 0上增加如下规则
action transparent
  ip-mask add ruleid 1 ipv4-sip 10.135.237.138/32 ipv4-dip 224.0.0.18/32 static
增加规则后,异常流量放行,不再送入计算板。计算板已不丢包。
