The default policy map is the "global" policy-map. If you want to send the traffic on all interfaces, through the SSM module, you dont need to create a new policy-map, you only need to create the class mathing the traffic you need to send via SSM module. Then you can include this class also in the policy-map applied globally.
With above said, assuming you have default policy-map config, if I implement following commands to divert all traffic via SSM module:
access-list ips-acl permit ip any any
class-map ips-class
match access-list ips-acl
policy-map global_policy
class ips-class
ips inline fail-open
Thus final policy-map configuration would look like:
policy-map global_policy
class inspection_default
inspect h323 h225
inspect h323 ras
inspect rsh
inspect rtsp
inspect esmtp
inspect sqlnet
inspect skinny
inspect sunrpc
class ips-class
ips inline fail-open
service-policy global_policy global
Alternatively, I cann apply the ips class to altogether a new policy-map but I cant apply this policy-map globally. I can apply the new policy-map to a particular interface though.
Hope that helps.
