# CSCF ISC Template Configuration Mode Commands

The CSCF ISC Template Configuration Mode is used to configure the IMS Service Control (ISC) interface within the system.

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
cnsa

Core Network Service Authorization (CNSA) related commands used to create media profile and service ids.
Platform:

ASR 5000
Product:

SCM (S-CSCF)
Privilege:

Administrator
Syntax

    cnsa { media-profile-id profile_id | service-id service_id  [ service_id ]...[ service_id ] }no cnsa { media-profile-id | service-id [ service_id ]  [ service_id ]...[ service_id ] }

media-profile profile_id

Specifies the cnsa media profile id.

profile_id must be an integer from 0 to 10.

The media profile id is assigned to a service policy using the cnsa-media-profile command under CSCF Service configuration.

IMPORTANT:

You can only create one media profile id per ISC template.
service-id service_id

Specifies the cnsa service id(s). These ids represent URN parameters which are ICSI (IMS Communication Service Identifier) values that are mapped to a service profile through a media profile id.

service_id must be from 1 to 79 alpha and/or numeric characters.
no cnsa { media-profile-id | service-id [ service_id ] [ service_id ]... [ service_id ] }

Removes a media profile or service id(s).
Usage:

Use this command to configure cnsa media profile ids and service ids. Information for core network authorization is received from HSS. It contains a list of service ids and a media profile id. Since the media profile id is an integer value, the S-CSCF needs to have a static database that contains the mapping between the integer value and the subscribed media profile. The media profile id is assigned to this service policy using the cnsa-media-profile command under CSCF Service configuration.

The S-CSCF selects the service profile based on the media profile id set and the policies, such as enforce-codec-policy and video-sessions, will be matched with the incoming request. Other policies, if configured, will be ignored in this scenario.
Example:
The following command defines the media profile id as 2:

    cnsa media-profile-id 2

The following command defines several service ids:

    cnsa service-id xxx:exampletelephony.version1 xxx:abc.com

end

Exits the current mode and returns to the Exec Mode.

IMPORTANT:

Filter criteria can be assigned to more than one ISC template.
Usage:

Use this command to configure the filter criteria to be used by this template.
Example:
The following command identifies the filter criteria 1:

    filter-criteria id 1
