Controlling PCF and SMF Interaction

PCF and SMF interaction for subscriber calls is enabled by default. To disable the PCF interaction with SMF, use the following sample configuration:

config 
   profile dnn dnn_profile_name 
      pcf-interaction { false | true } 
      end 

NOTES:

  • profile dnn dnn_profile_name : Specify the DNN profile name. dnn_profile_name must be an alphanumeric string.

  • pcf-interaction { false | true } : Disable or enable the interaction with PCF.

    • false : SMF does not interact with PCF.

    • true : SMF interacts with PCF wherever applicable as part of all call flows. This is the default configuration.

Configuration Example

The following is an example configuration.

config
profile dnn intershat1
pcf-interaction false
end

Configuration Verification

Check the pcf-interaction configuration to determine if PCF interaction with SMF is enabled or disabled. To verify the configuration, use the following command at the Exec mode:

show running-config profile dnn intershat1 

You can also verify the feature configuration using the following show command at the Global Configuration mode.

show full-configuration profile dnn intershat1 

The following is an example output of the show running-config profile dnn intershat1 command.

[smf] smf# show running-config profile dnn intershat1
profile dnn intershat1

The following is an example output of the show full-configuration profile dnn intershat1 command.

[smf] smf(config)# show full-configuration profile dnn intershat1
profile dnn intershat1
 dns primary ipv4 209.165.200.239
 dns primary ipv6 fd01:976a::9

 pcscf-profile    PCSCF_Prof_2
 ssc-mode 1

 upf apn intershat1
 pcf-interaction  false
exit 

In the preceding examples, pcf-interaction false is displayed, indicating that SMF does not interact with PCF.
