Note

For PCSI LI configuration, refer to Configuring Distributed SBC for Lawful Interception as it is supported only on the D-SBC.

 

Configuring the Call Data Channel

To configure PCSI LI:

Configuring the Node Number

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 SBC Core IPsec

### enable IPsec on the IP interface group
  
set addressContext default ipInterfaceGroup LIG1 enabled

Configuring CDC with IP Interface Group

To configure the IP Interface Group, execute the following command:

set addressContext default intercept callDataChannel CDC ipInterfaceGroupName LIG1

commit

Configuring CDC for Media Interception

The PCSI LI supports configuring up to 8 mediation servers under the CDC.

set addressContext default intercept callDataChannel CDC interceptStandard mediationServer MS1
commit

Configuring CDC for Media Interception over TCP

set addressContext default intercept callDataChannel CDC mediationServer MS1 media tcp ipAddress fc22:3200::230:7 portNumber 8765 dscpValue 0

Viewing PCSI LI Configuration

Enter the show commands to view the configurations.

Viewing the Intercept Details

To view the intercept details, execute the following command:

> show status addressContext default intercept callDataChannel
callDataChannel CDC {
    mediationServerMediaStatus MS1 {
        tcpChannelstatus inService;
        tcpPacketsSent   0;
        tcpPacketsLost   0;
        udpPacketsSent   0;
        udpPacketsLost   0;
    }
}
[ok]

Viewing the CDC Configuration

To view the CDC configuration, execute the following command:

show addressContext default intercept callDataChannel CDC
interceptStandard    packetcable;
vendorId             ss8;
ipInterfaceGroupName LIG1;
mediationServer MS1 {
    media {
        tcp {
            ipAddress  10.54.6.1;
            portNumber 8765;
            dscpValue  0;
            mode       inService;
            state      enabled;
        }
    }
