背景
局域网中大概有600-700台使用的电脑,最近有个别电脑出现网络偶尔性闪断的情况,造成业务无法正常进行。经过重做水晶头等方式,确定了线路是正常的。还是无法解决。处理步骤
一、查看交换机的日志发现,交换机里面有大量的接口异常信息。Apr 25 2021 18:10:18 MT037 %%01MSTP/4/SET_PORT_FORWARDING(l)[316]:In MSTP process 0 instance 0, MSTP set port GigabitEthernet0/0/35 state as forwarding.

备注:
配置流量抑制示例 配置流量抑制后的广播、未知单播和组播报文的速率为接口速率的 % 1. 进入接口视图<Quidway> system-view [Quidway] interface gigabitethernet 2/0/122. 配置广播流量抑制
[Quidway-GigabitEthernet2/0/12] broadcast-suppression 803. 配置组播流量抑制
[Quidway-GigabitEthernet2/0/12] multicast-suppression 804. 配置未知单播流量抑制
[Quidway-GigabitEthernet2/0/12] unicast-suppression 805. 验证配置结果 执行命令display flow-suppression interface查看GE0/0/1接口下的流量抑制配置情况。
