Cisco ASA Series CLI Configuration Guide
Chapter 1 Configuring Inspection for Voice and Video Protocols
H.323 Inspection
b.
Specify the action you want to perform on the matching traffic by entering the following command:
hostname(config-pmap-c)# {[ drop [ send-protocol-error ] |
drop-connection
[
send-protocol-error
]|
mask
|
reset
] [
log
] |
rate-limit
message_rate }
Not all options are available for each match or class command. See the CLI help or the command
reference for the exact options available.
The drop keyword drops all packets that match.
The send-protocol-error keyword sends a protocol error message.
The drop-connection keyword drops the packet and closes the connection.
The mask keyword masks out the matching portion of the packet.
The reset keyword drops the packet, closes the connection, and sends a TCP reset to the server
and/or client.
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.
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 .
Step 7
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 enable call setup betweeen H.323 Endpoings, enter the following command:
hostname(config)# ras-rcf-pinholes enable
You can enable call setup between H.323 endpoints when the Gatekeeper is inside the network. The
ASA includes options to open pinholes for calls based on the
RegistrationRequest/RegistrationConfirm (RRQ/RCF) messages. Because these RRQ/RCF
messages are sent to and from the Gatekeeper, the calling endpoint's IP address is unknown and the
ASA opens a pinhole through source IP address/port 0/0. By default, this option is disabled.
c.
To define the H.323 call duration limit, enter the following command:
hostname(config-pmap-p)# call-duration-limit time
Where time is the call duration limit in seconds. Range is from 0:0:0 ti 1163:0;0. A value of 0 means
never timeout.
d.
To enforce call party number used in call setup, enter the following command:
hostname(config-pmap-p)# call-party-number
e.
To enforce H.245 tunnel blocking, enter the following command:
hostname(config-pmap-p)# h245-tunnel-block action {drop-connection | log}
f.
To define an hsi group and enter hsi group configuration mode, enter the following command:
hostname(config-pmap-p)# hsi-group id
Where id is the hsi group ID. Range is from 0 to 2147483647.
To add an hsi to the hsi group, enter the following command in hsi group configuration mode:
