Configuring the LI Call Data Channel (CDC)

Configuring the Node Number LI

As user 'Calea', use the following commands to configure LI:

% set addressContext default intercept  
   nodeNumber <integer>

Note
  • If the CDC is configured through the EMS, the node number is configured automatically by the EMS.
  • If the CDC is configured through the SBC, the node number must be configured along with the CDC on the SBC.

Configuring the Default LI in the I-SBC or S-SBC

Use the following command to establish the LI call data channel configuration in the I-SBC or S-SBC.

% set addressContext default intercept callDataChannel <callDataChannel_name>
   interceptStandard <etsi | packetcable | packetcablePlusEtsi | threeGpp>
   ipInterfaceGroupName <ipInterfaceGroup_name>
   kaTimer <kaTimer_value>
   priIpAddress <IP_Address>
   priMode <active | outofservice | standby>
   priPort <priPort_number>
   priState <disabled | enabled>
   retries <value>
   secIpAddress <IP_Address>
   secMode <active | outofservice | standby>
   secState <disabled | enabled>
   vendorId <none | ss8 | utimaco | verint>

 

The following is an example of how to configure the default LI in the I-SBC.

% set addressContext default intercept callDataChannel <callDataChannel_name> ipInterfaceGroupName <ipInterfaceGroup_Name> interceptStandard <etsi | packetcable | packetcablePlusEtsi | threeGpp> kaTimer <kaTimer_value> priIpAddress <IP_Address> priMode active priPort <priPort_number> priState enabled retries 3 secIpAddress <IP_Address> secMode standby secState enabled vendorId <none | ss8 | utimaco | verint>

Configuring the Default LI in the M-SBC

Use the following command to establish the LI call data channel configuration in the M-SBC.

% set addressContext default intercept callDataChannel <callDataChannel_name>
   interceptStandard < etsi | packetcable | packetcablePlusEtsi | threeGpp>
   kaTimer <kaTimer_value>
   priIpAddress <IP_Address>
   priMode <active | outofservice | standby>
   priPort <priPort_number>
   priState <disabled | enabled>
   retries <value>
   secIpAddress <IP_Address>
   secMode <active | outofservice | standby>
   secState <disabled | enabled>
   vendorId <none | ss8 | utimaco | verint>

Configuring the SBC Core IPsec

As user ''Admin'', use the following commands to configure IPsec:

Note
  •  This optional configuration is needed if secure connection is required between the SBC and the Mediation Server.  
  • The SBC does not support IPsec for media interception over UDP.
  • The SPD entry is required to create the following entries:

    • localIdentity ipAddress – The SBC Interface Group IP associated with the LI CDC.

    • remoteIdentity ipAddress – The Mediation Server IP configured in the LI CDC.

  • The Recommended setting for LI IPsec mode is 'transport'.

Info

For more information on IPsec configuration, refer to the section IP Security - CLI.

Viewing the Default LI Configuration Statistics

As user 'Calea', use the following command in System-level mode to retrieve the LI statistics:

> show status addressContext default intercept interceptCallDataChannelStatistics
interceptCallDataChannelStatistics default { 
    primaryChannelStatus    inService;
    secondaryChannelStatus  outOfService;
    StartSuccess            0;
    StartFailures           0;
    StopSuccess             0;
