阻断dot1x报文的方法

现场由于dot1x报文过多，导致现场交换机的pon芯片负载过高业务异常，需要先把dot1x报文先丢弃恢复业务

目前看到slot10的pon芯片都发生了多次updown

  ====dis hardware internal epon olt chipstatus chassis 1 slot 10 chip 0==== 

    CHIPID    STATUS    DOWN_CNT    UP_CNT    LOAD_CNT    CHIP_GEMODE

      0       UP           34         81        47         0

====================================================================

  ====dis hardware internal epon olt chipstatus chassis 1 slot 10 chip 1==== 

    CHIPID    STATUS    DOWN_CNT    UP_CNT    LOAD_CNT    CHIP_GEMODE

      1       UP           35         60        26         0

====================================================================

  ====dis hardware internal epon olt chipstatus chassis 1 slot 10 chip 2==== 

    CHIPID    STATUS    DOWN_CNT    UP_CNT    LOAD_CNT    CHIP_GEMODE

      2       UP           35         61        26         0

====================================================================

而且slot 10单板的SC_Q_CORE队列已经满了，出现队列put_error丢包。

怀疑是大量的dot1x报文冲击的olt的pon芯片，造成pon芯片updown。

建议在与olt相连的核心设备的聚合口配置包过滤，把dot1x（0x888e）报文丢掉。
