Re: To block URLs on cisco 7507 router

you can do this by enabling the Nbar on interface and then make class-map test do match protocol http url "*hotmail*"

then make policy-map test

class test

drop

apply the service on interface.

Re: To block URLs on cisco 7507 router

I have done same thing as:

class-map match-all test

match protocol http url "youtube"

!

!

policy-map test

class test

set ip dscp default

enable ip nbar protocol-discovery on Fa5/1/1

following are access-list applied on fa5/1/1

40 deny ip any any dscp default (105222matches)

50 permit ip any any log (868 matches)

But it blocks all the site not even youtube.I am unable to open any site like yahoo,google,rediff etc.

Please tell me..

Re: To block URLs on cisco 7507 router

You're denying all IP traffic with a DSCP of 0, which is what most traffic is by default.

Try something like this-

class-map match-all test

match protocol http host *youtube.com*

policy-map test

class test

drop

You can remove the the ACL line 40 & 50.

Hope that helps.

Re: To block URLs on cisco 7507 router

Take a look at Method 3 on the link you provided, that would be a way to do it as well.
