Hi,all:
my config like this:
Class Map match-all 1 (id 3)
Match protocol dns
Class Map match-all 2 (id 4)
Match protocol http host "*cisco.com*"
Class Map match-all 3 (id 5)
Match not class-map 1
Match not class-map 2
Policy Map 1
Class 1
Class 2
Class 3
drop
I want deny all web access except to cisco.com
If i not use "drop" command in class 3,i can see packets match stats in class 2 when i use command "show policy-map interface";but if i use "drop" command in class 3,all http packets will be droped,i can't access the cisco.com,and there is any packets match stats in class 2,but class 1 and class 3's match stats grow up correct,i try some other way for class 3,like:
class 3
match class class-default
or
class 3
match any
or
class 3
match access-group xxx
but all fail,the router drop all http packets as long as "drop" command be used in class3.
please help me,thx

Hello,
If you looking to block all web access except ciso.com site, then you need to use REGEX. Here is a document that could be helpful.

Hope this helps.
