CSCF Policy Rules Configuration Mode Commands


CSCF Policy Rules Configuration Mode Commands
 
 
The CSCF Policy Rules Configuration Mode is used to manage CSCF AoR and service policy profiles within the system.
 
Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
 
allow-noauth
Configures the policy to allow unauthenticated access. Default is disabled.
Product
SCM
Privilege

Syntax
[ default | no ] allow-noauth
default | no
Disables the allow-noauth functionality for this policy.
Usage
Use this command to allow access to subscribers without authenticating them.
 
allow-unsecure
Configures the policy to allow access to the system without a security association. Default is disabled.
Product
SCM
Privilege
Administrator
Syntax
[ default | no ] allow-unsecure
default | no
Disables the allow-unsecure functionality for this policy.
Usage
Use this command to enable the policy to provide subscriber access to system without a security association.
 
authorization
Configures the policy to allow early bandwidth authorization. Default is disabled.
Product
SCM
Privilege
Administrator
Syntax
[ default | no ] authorization early-bandwidth
default | no
Disables the early bandwidth authorization functionality for this policy.
Usage
Use this command to enable the policy to provide early bandwidth authorization.
 
end
Exits the current mode and returns to the Exec Mode.
Product
All
Privilege
Administrator
Syntax
end
Usage
Change the mode back to the Exec mode.
 
enforce-codec-policy
Enters the Enforce Codec Policy Command Mode where allowed static and dynamic codec lists are managed.
Product
SCM
Privilege
Administrator
Syntax
[ default | no ] enforce-codec-policy
default | no
Disables the codec policy.
Usage
Use this command to enter the Enforce Codec Policy Configuration Mode.
Entering this command results in the following prompt:
[context_name]hostname(config-policy-enforce-codec)#
CSCF Enforce Codec Policy Mode commands are defined in the Enforce Codec Policy Configuration Mode Commands chapter in this guide.
 
exit
Exits the current mode and returns to the previous mode.
Product
All
Privilege
Administrator
Syntax
exit
Usage
Return to the previous mode.
 
max-cscf-concurrent-sessions
Configures the maximum number of concurrent sessions allowed per subscriber.
Product
SCM
Privilege
Administrator
Syntax
max-cscf-concurrent-sessions number
default max-cscf-concurrent-sessions
number
Default: 5
Specifies the number of concurrent sessions allowed per subscriber for this policy. number must be an integer from 1 to 100.
default
Resets defaults for this command.
Usage
Use this command to set the maximum number of allowed sessions per subscriber for this policy.
If enabled, the subscriber-policy-override command in the CSCF Service Configuration Mode overrides the service-level policy.
Example
The following command sets the maximum number of concurrent sessions for a subscriber using this policy to 7:
max-cscf-concurrent-sessions 7
 
policy
Configures the overload response for this policy. When the P-CSCF/A-BG becomes congested, this overload policy is used to reject subsequent sessions or redirect them to another server.
Product
SCM (P-CSCF, A-BG)
Privilege
Administrator
Syntax
policy overload { redirect address1 [ weight weight1 ] [ address2 [ weight weight2 ] ] ... | reject [ use-reject-code { admin-prohibited | insufficient-resources } ] }
default policy overload
no policy overload redirect address1[address2] ...
redirect address1 [ weight weight1 ] [ address2 [ weight weight2 ] ] ...
Specifies that upon policy overload, the system will redirect the session to another CSCF.
address1 must be expressed in dotted decimal notation for IPv4 or colon notation for IPv6.
weight weight1: Defines the priority of the redirect address.
weight1 must be an integer from 1 to 10. Default is 1.
reject [ use-reject-code { admin-prohibited | insufficient-resources } ]
Specifies that upon policy overload, the system will reject the session. This is the default setting.
use-reject-code: Specifies that a reject code will be returned upon policy overload.
default policy overload
Resets defaults for this command.
no policy overload redirect address1 [ address2 ] ...
Removes configured policy overload redirect address(es).
Usage
Use this command to define the response to an overload condition on the P-CSCF/A-BG using this AoR policy.
Example
The following command configures the policy overload response to redirect to a series of CSCFs with IP address of 1.2.3.4, 1.2.3.5, and 1.2.3.6 with respective priorities (weights) of 1, 3, and 2:
policy overload redirect 1.2.3.4 weight 1 1.2.3.5 weight 3 1.2.3.6 weight 2
 
qos
Configures QoS bandwidth settings for uplink and downlink.
Product
SCM
Privilege
Administrator
Syntax
qos bandwidth { downlink| uplink } [ peak value ]
bandwidth { downlink| uplink }
downlink: Configures the downlink bandwidth.
uplink: Configures the uplink bandwidth.
peak value
Peak value of bandwidth in kilobits per second (kbit/s).
value must be an integer from 1 to 99999999.
Usage
The P-CSCF/A-BG fills the required bandwidth for downlink and uplink from the Session Description Protocol (SDP) in the message when communicating with an external policy server via Rx/Tx/Gq. Use this command to configure the peak uplink and downlink bandwidth to be used when the SDP does not contain bandwidth.
Example
Set the peak uplink bandwidth to 256 kbit/s:
qos bandwidth uplink peak 256
 
video-sessions
Configures the policy to allow video bearers. Default is disabled.
Product
SCM
Privilege
Administrator
Syntax
[ default | no ] video-sessions
default | no
Disables the “allow video sessions” feature.
Usage
Use this command to allow video session via this policy.
