用于控制 Worm_MSBlast.A 蠕虫的传播
rule deny udp source any destination any destination-port eq 1434
下面的不出名的病毒端口号 （可以不作）
rule deny tcp source any destination any destination-port eq 1068
rule deny tcp source any destination any destination-port eq 5800
rule deny tcp source any destination any destination-port eq 5900
rule deny tcp source any destination any destination-port eq 10080
rule deny tcp source any destination any destination-port eq 455
rule deny udp source any destination any destination-port eq 455
rule deny tcp source any destination any destination-port eq 3208
rule deny tcp source any destination any destination-port eq 1871
rule deny tcp source any destination any destination-port eq 4510
rule deny udp source any destination any destination-port eq 4334
rule deny tcp source any destination any destination-port eq 4331
rule deny tcp source any destination any destination-port eq 4557
然后下发配置
packet-filter ip-group 100
目的：针对目前网上出现的问题，对目的是端口号为1434的UDP报文进行过滤的配置方法，详细和复杂的配置请看配置手册。
NE80的配置：
NE80(config)#rule-map r1 udp any any eq 1434
//r1为role-map的名字，udp 为关键字，any any 所有源、目的IP，eq为等于，1434为udp端口号
