Configuring the SIP Edge proxy server for a load balancer with MAC address forwarding
Configure the IBM® SIP Edge Proxy that sits in front of the Sametime® Media Manager components in a load-balancing environment.
About this task
If you choose MAC address forwarding, then you must provide a loopback adapter by completing the steps in this topic and its subtopics. This topic is only for MAC address forwarding.
If you want to use the IP forwarding method for load balancing, follow the instructions in Achieving High Availability with Websphere Application Server SIP Container and F5 BIG-IP Local Traffic Manager . These instructions are for the IP forwarding method.
Procedure
Complete the following steps on every SIP Edge Proxy
server to configure them for load balancing.
- Create a user-defined SIP port:
- On the SIP Edge Proxy server, log into the Integrated Solutions Console as the WebSphere® administrator.
- Click .
- In the Communications section, click Ports.
- Create a non-secure SIP port.
- Click New.
- Select User-defined Port.
- In Specify Port Name field enter PROXY_SIP_ADDRESS_LB.
- Enter a value for the Host field. This is the virtual IP (cluster address) that is configured on your load balancer.
- In the Port field enter the non-secure SIP port value (such as, 5060). This value corresponds to the port through which the load balanced servers are configured to accept traffic.
- Click OK and save the changes
- Return to the Ports screen
- To create a secure SIP port click New.
- Select User-defined Port.
- In the Specify Port Name field enter PROXY_SIPS_ADDRESS_LB.
- Enter a value for the Host field. This is the virtual IP (cluster address) that is configured on your load balancer.
- In the Port field type the secure SIP port value (such as, 5061). This value corresponds to the port through which the load balanced servers are configured to accept traffic.
- Click OK and save the changes. Repeat for each WebSphere Proxy Server. Note that all proxy servers that operate with a particular cluster, must use the same SIP ports.
- Modify the SIP Edge Proxy server transports:
- Back in the navigation tree, click .
- In the Proxy Settings section, click .
- Modify the transport chain for TLS by clicking SIPS_PROXY_CHAIN.
- Click TCP inbound channel in the Transport Channels section.
- From the Port list select PROXY_SIPS_ADDRESS_LB.
- Click OK and save the changes.
- Return to the SIP proxy server transports screen.
- Modify the transport chain for TCP by clicking SIP_PROXY_CHAIN.
- Click TCP inbound channel in the Transport Channels section.
- From the Port list select PROXY_SIP_ADDRESS_LB.
- Click OK and save the changes.
- Return to the SIP proxy server transports screen.
- Modify the transport chain for UDP by clicking UDP_SIP_PROXY_CHAIN.
- Click UDP inbound channel in the Transport Channels section.
- From the Port list select PROXY_SIP_ADDRESS_LB.
- Click OK, save the changes, and repeat for each WebSphere Proxy Server.
- Modify SIP proxy settings:
