individual match commands. Enter an integer from 2 to 1024 as the line

This section describes how to configure a Layer 7 SIP inspection policy map. The
Layer 7 policy map configures the applicable SIP inspection actions executed on
the network traffic that matches the classifications defined in a class map. You
then associate the completed Layer 7 SIP inspection policy with a Layer 3 and
Layer 4 policy map to activate the operation on a VLAN interface (see the
"Defining Layer 3 and Layer 4 Application Protocol Inspection Policy Actions"
section).
