> [ default | no ] allow-unsecure
> default | no
> Disables the allow-unsecure functionality for this policy.

> Administrator
> Syntax
> [ default | no ] authorization { early-bandwidth | prov-response }
> early-bandwidth

> prov-response
> Enables AAR for provisional responses like 18X.
> default | no
> Disables the early bandwidth or provisional response authorization functionality for this policy.
> Usage
> Use this command to enable the policy to provide early bandwidth or provisional response 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.

> • | admin-prohibited: Specifies that the “admin-prohibited” reject code will be returned upon policy overload.

> • | insufficient-resources: Specifies that the “insufficient resources” reject code will be returned upon policy overload. This is the default reject code.

> 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.
