Chapter 1 Configuring Inspection for Voice and Video Protocols
Skinny (SCCP) Inspection
The log keyword, which you can use alone or with one of the other keywords, sends a system log
message.
The rate-limit message_rate argument limits the rate of messages.
Step 6
You can specify multiple class or match commands in the policy map. For information about the order
of class and match commands, see the “Defining Actions in an Inspection Policy Map” section on
page 1-4 .To configure parameters that affect the inspection engine, perform the following steps:
a.
To enter parameters configuration mode, enter the following command:
hostname(config-pmap)# parameters
hostname(config-pmap-p)#
b.
To enforce registration before calls can be placed, enter the following command:
hostname(config-pmap-p)# enforce-registration
c.
To set the maximum SCCP station message ID allowed, enter the following command:
hostname(config-pmap-p)# message-ID max hex_value
Where the hex_value argument is the station message ID in hex.
d.
To check RTP packets flowing on the pinholes for protocol conformance, enter the following
command:
hostname(config-pmap-p)# rtp-conformance [enforce-payloadtype]
Where the enforce-payloadtype keyword enforces the payload type to be audio or video based on
the signaling exchange.
e.
To set the maximum and minimum SCCP prefix length value allowed, enter the following command:
hostname(config-pmap-p)# sccp-prefix-len {max | min} value_length
Where the value_length argument is a maximum or minimum value.
f.
To configure the timeout value for signaling and media connections, enter the following command:
hostname(config-pmap-p)# timeout
The following example shows how to define an SCCP inspection policy map.
hostname(config)# policy-map type inspect skinny skinny-map
hostname(config-pmap)# parameters
hostname(config-pmap-p)# enforce-registration
hostname(config-pmap-p)# match message-id range 200 300
hostname(config-pmap-p)# drop log
hostname(config)# class-map inspection_default
hostname(config-cmap)# match default-inspection-traffic
hostname(config)# policy-map global_policy
hostname(config-pmap)# class inspection_default
hostname(config-pmap-c)# inspect skinny skinny-map
hostname(config)# service-policy global_policy global
