如何在CISCO路由器上禁止BT下载
作者:
方法有多种,常见的有:
1、找出ip做端口限速(这样做比较麻烦)
2、用NBAR(非常好用)
但是重新启动需要重新调用 tftp://130.130.122.123/bittorrent.pdlm 这个文件,所以还是用flash卡比较好。如果不调用文件,那就会发生没有match protocol bittorrent
ip nbar pdlm tftp://130.130.122.123/bittorrent.pdlm
class-map match-all bit
match protocol bittorrent
policy-map limit-bit
