问题描述：
S5560 每个端口都做了vlan，前1-6个端口分别下联二层交换，其他端口作1个VLAN 供服务器组使用。
前一周突然出现部分断网，查找发现有一台二层交换下的设备无法获取到IP，测试二层无法ping通，无法登录，当时认为是二层问题，重置后 导入配置，显示成功，重启后 查看配置是没有的，折腾多次都没用，后续直接当傻瓜交换机，不要任何配置，接在其他二层上 却能正常使用。
后续华三工程师让我测试下 三层是否能获取到地址， 结果不管是下联二层接口 还是服务器组端口 都无法获取到ip， 我连接到服务器vlan 手动ip也无法上网，然后 华三工程师怀疑是三层故障问题，当时也把三层配置给他看过 没发现问题。刚刚打完华三电话 准备提个单子， 结果刚过保 不支持电话。。。。。 大佬们给看看是啥原因，
