Chapter 1 Configuring Inspection of Basic Internet Protocols
hostname(config-pmap)# class class_map_name
hostname(config-pmap-c)#
•
Specify traffic directly in the policy map using one of the match commands described in
you use a match not command, then any traffic that does not match the criterion in the match not
command has the action applied.
You can specify multiple class or match commands in the policy map. For information about the order
of class and match commands, see the
page 1-4.
Step 7
Specify the action you want to perform on the matching traffic by entering the following command:
hostname(config-pmap-c)# {drop-connection | reset | log}
Where the drop-connection action closes the connection. The reset action closes the connection and
sends a TCP reset to the client. The log action sends a system log message when this policy map matches
traffic.
The following example shows how to define an IM inspection policy map.

hostname(config)# regex loginname2 "Kevin\@yahoo.com"
