RE: deny access

Always an ACL puts a "deny any any" at the end, so be careful to put your
ACL with all the permits before the end, or you may end up closing your
access to everything (maybe even your router).

For QoS, with ACL, you can look at the rate-limit command (at the interface
configuration) usage, which defines by bandwith size perecentage, how much
bandwith will be used and what will happen if the link becomes too used. The
? will help you understand the command, since it has many options.

regards

OA

HI
Simply create an deny access list to block this IP.

Access-list 101 deny ip source ip destination ip



Thanks & Regards,
