COPS-based CLF Configuration

In the following configuration examples, we assume that your baseline configuration passes SIP traffic, with the Oracle Communications Session Border Controller in the role of an Access Oracle Communications Session Border Controller . In this example, you will configure additions to the ream configuration and the new external policy server configuration.

SIP Interface Configuration

To configure the SIP interface configuration for CLF support:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type session-router and press Enter to access the session-related configurations.
```
ORACLE(configure)# session-router
```
Type sip-interface and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(media-manager)# sip-interface
ORACLE(sip-interface)#
```
Type select and the number of the pre-configured sip interface you want to configure for CLF. This should be the ingress SIP interface for
```
ORACLE(sip-interface)# select 1
ORACLE(sip-interface)#
```
ext-policy-svr—Set this parameter to the same name as the External Policy Server configured that you configured for the CLF server.
default-location-string—Set this parameter to the default location string you want inserted into a P-Access-Network-Info header for when the CLF server does not return a unique location string.
Save your work using the ACLI done command.

To configure the external policy server for use with a CLF:
In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type media-manager and press Enter to access the media-related configurations.
```
ORACLE(configure)# media-manager
```
Type ext-policy-server and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.
```
ORACLE(media-manager)# ext-policy-server
ORACLE(ext-policy-server)#
```
name—Set this parameter to an applicable name for this CLF instance of the external policy server. The value of this parameter will be entered in the SIP interface configuration element to reference this CLF.
state—Set this parameter to enabled to enable this CLF. The default value is enabled. The valid values are:
- enabled | disabled
operation-type—Set this parameter to admission-control for the Oracle Communications Session Border Controller to communicate with a CLF. The default value is disabled.
protocol—Set this parameter to COPS to connect with a CLF via the COPS protocol. The default value is C-SOAP. The valid values are:
- COPS—Standard COPS implementation. COPS client type is 0x7929 for CLF, and 0x7926 for PDP/RACF usage as defined in the operation-type parameter.
- A-COPS—Vendor specific protocol. COPS client type is 0x4AC0 for admission-control operation-type.
address—Set this parameter to the IP address or FQDN of the CLF.
port—Set this parameter to the port which the CLF uses for COPS transactions. The standard port for COPS is 3288. The default value is 80. The valid range is:
- Minimum—0
- Maximum—65535
realm—Set this parameter to the realm in which the CLF exists.
num-connections—Set this parameter to the number of connections the Oracle Communications Session Border Controller will create with the CLF. The default value is 1. The valid range is:
- Minimum—0
- Maximum—65535
reserve-incomplete—Set this parameter to enabled if you want the Oracle Communications Session Border Controller to send a COPS REQ message to the CLF that does not include the endpoint’s true port number. A value of 0 will be used for the port number. The default value is enabled. The valid values are:
- enabled | disabled
