当网络时断时续,网页弹出各种出错ping内网关request out时断时续,考虑网络arp病毒;装个arp防火墙,找出攻击源,离线杀其毒,清除网内ARP表,然后路由,绑定arp网关及各主机对应mac,有效解决arp病毒广播,划分vlan或实行主机pppoe拔号上网,

主机上相关操作

cmd 里

@echo off

arp -d

arp -s ip mac

arp -a

路由上(cisco)

clear ip arp

arp ip mac arpa int f0/1

dhcp snooping enable

ip source binding vlan 10 ip mac int f0/1

show arp|include 攻击源mac

华为、H3C路由器上
