Configuring SIP SLB

Example
Displaying SIP virtual server connection rate
Use the show server sip-hash proxy vs command to display the hash table for a virtual server.
ServerIronADX(config)# show server sip-hash proxy-domain-1
Syntax: show server sip-hash <virtual-server-name>
Example
Stateful SIP session handling in the event of a proxy server failure
ServerIron can seamlessly handle failure of proxy servers while running in stateful mode. The
ServerIron can be enabled to re-route subsequent SIP packets on an existing flow for a failed proxy
server to an available healthy proxy server. However, note that the backend SIP proxy server should
have the capability of handling such SIP calls which were originally serviced by a different proxy
server.
This feature is generally useful when backend proxy servers are configured in cluster configuration.
Enter the following command.
ServerIronADX(config)# server sip enable-session-failover-on-server-failure
Syntax: [no] server sip enable-session-failover-on-server-failure
ServerIronADX# show server sip-conn proxy-server-1
