All the http traffic will match this rule. Below you can see "set connection" applied to class http_traffic that matches port 80. Will this work? All the http traffic will match class inspection_default and how will http traffic again match against class http_traffic? Query 2 hostname(config)# class-map im_inspect_class_map hostname(config-cmap)# match default-inspection-traffic hostname(config)# policy-map type inspect im im_policy_all hostname(config-pmap)# class yahoo_file_block_list hostname(config-pmap-c)# match service file-transfer hostname(config-pmap)# class yahoo_im_policy hostname(config-pmap-c)# drop-connection hostname(config-pmap)# class yahoo_im_policy2 hostname(config-pmap-c)# reset hostname(config)# policy-map global_policy_name hostname(config-pmap)# class im_inspect_class_map hostname(config-pmap-c)# inspect im im_policy_all match default-inspection-traffic. What does default-inspection-traffic match. Does it match any traffic or only the ports that the ASA can inspect. If you check in ASA, the default-inspection-traffic does not have a por defined for IM. asa/king(config-cmap)# match ? mpf-class-map mode commands/options: access-list Match an Access List any Match any packet default-inspection-traffic Match default inspection traffic: ctiqbe----tcp--2748 dns-------udp--53 ftp-------tcp--21 gtp-------udp--2123,3386 h323-h225-tcp--1720 h323-ras--udp--1718-1719 http------tcp--80 icmp------icmp ils-------tcp--389 mgcp------udp--2427,2727 netbios---udp--137-138 radius-acct---udp--1646 rpc-------udp--111 rsh-------tcp--514 rtsp------tcp--554 sip-------tcp--5060 sip-------udp--5060 skinny----tcp--2000 smtp------tcp--25 sqlnet----tcp--1521 tftp------udp--69 waas------tcp--1-65535 xdmcp-----udp--177 If it doesn't have a port for IM, how will it be inspected?
