Blocking Applications in IOS

Category:Cisco Systems -> Security

In Cisco IOS it is possible to block some kinds of p2p traffic like Skype or Bittorrent etc. All you need is just a simple rule for this:


class−map match−any p2p
match protocol skype
match protocol bittorrent

policy−map Disallow−p2p
class p2p 

int FastEthernet0
description Inbound
service−policy input Disallow−p2p 

If it doesn’t work, try upgrading IOS and try to avoid x.0 revisions.
