To Set Up Traffic Separation

1. Set the address attribute of SIP listeners and HTTP listeners to the external address of the mutli-homed machine.

   Use the following commands:

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.sip-service.sip-listener.sip-listener1.address=\${EXTERNAL_LISTENER_ADDRESS}

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.http-service.http-listener.http-listener1.address=\${EXTERNAL_LISTENER_ADDRESS}

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.sip-service.sip-listener.sip-listener2.address=\${EXTERNAL_LISTENER_ADDRESS}

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.sip-service.http-listener.http-listener2.address=\${EXTERNAL_LISTENER_ADDRESS}

2. Set the listener type of these listeners as external, so that they listen for traffic from User Agents and not for the converged load balancer proxying.

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.sip-service.sip-listener.sip-listener1.type=external

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.http-service.http-listener.http-listener1.type=external

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.sip-service.sip-listener.sip-listener2.type=external

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.sip-service.http-listener.http-listener2.type=external

3. Create the system properties EXTERNAL_LISTENER_ADDRESS and INTERNAL_LISTENER_ADDRESS.

   • asadmin create-system-properties --user admin --port 4848 --passwordfile password.txt --target cluster1 EXTERNAL_LISTENER_ADDRESS=0.0.0.0:INTERNAL_LISTENER_ADDRESS=0.0.0.0

   • asadmin create-system-properties --user admin --port 4848 --passwordfile password.txt --target server EXTERNAL_LISTENER_ADDRESS=0.0.0.0:INTERNAL_LISTENER_ADDRESS=0.0.0.0

4. Create new listeners for listening to internal traffic.

   • asadmin create-sip-listener --user admin --port 4848 --passwordfile password.txt --target cluster1 --siplisteneraddress 0.0.0.0 --siplistenerport 25060 internal-sip-listener

   • asadmin create-http-listener --user admin --port 4848 --passwordfile password.txt --target cluster1 --listeneraddress 0.0.0.0 --defaultvs server --listenerport 28080 internal-http-listener

5. Set the address attribute of these new listeners to the internal address.

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.sip-service.sip-listener.internal-sip-listener.address=\${INTERNAL_LISTENER_ADDRESS}

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.http-service.http-listener.internal-http-listener.address=\${INTERNAL_LISTENER_ADDRESS}

6. Set the type attribute of these new listeners to internal.

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.sip-service.sip-listener.internal-sip-listener.type=internal

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1–config.http-service.http-listener.internal-http-listener.type=internal

7. Configure the IP address of the cluster instances.

   • asadmin create-system-properties --user admin --port 4848 --passwordfile password.txt --target instance101 EXTERNAL_LISTENER_ADDRESS=10.12.152.29:INTERNAL_LISTENER_ADDRESS=192.168.2.1

   • asadmin create-system-properties --user admin --port 4848 --passwordfile password.txt --target instance102 EXTERNAL_LISTENER_ADDRESS=10.12.152.39:INTERNAL_LISTENER_ADDRESS=192.168.2.3

   • asadmin create-system-properties --user admin --port 4848 --passwordfile password.txt --target instance103 EXTERNAL_LISTENER_ADDRESS=10.12.152.49:INTERNAL_LISTENER_ADDRESS=192.168.2.4

8. Restart the node agent and the cluster.

9. If you are using a hardware load balancer for spraying the SIP traffic to the individual instances, you need to set the external-sip-address and external-sip-port attributes to point to the hardware load balancer.

   If you are using only one hardware load balancer for all SIP listeners, set the attributes of the SIP container.

   • asadmin create-system-properties --user admin --port 4848 --passwordfile password.txt cluster1-config.sip-container.external-sip-address=yourlbaddress

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1-config.sip-container.external-sip-port=yourlbport

   If you are using multiple hardware load balancers, set the attributes of each of the SIP listeners:

   • asadmin create-system-properties --user admin --port 4848 --passwordfile password.txt cluster1-config.sip-service.sip-listener.sip-listener1.external-sip-address=yourlbaddress

   • asadmin set --user admin --port 4848 --passwordfile password.txt cluster1-config.sip-service.sip-listener.sip-listener1.external-sip-port=yourlbport
