Configuring SIP SLB
1
Configure a SIP virtual server
Follow the steps given below to configure SIP Server Load Balancing virtual redirect-proxy servers
and virtual proxy domains, and bind real severs to virtual servers.
1. Configure a virtual proxy-domain-name and IP address for Domain 1 and enter the virtual
server configuration mode.
ServerIronADX(config)# server virtual-name-or-ip proxy-domain-1 1.1.6.9
Syntax: [no] server virtual-name-or-ip <name> <ip address>
2. Specify the SIP port and SIP switch.
ServerIronADX(config-vs-proxy-domain-1)# port sip sip-switch
Syntax: [no] port sip sip-switch
This "must have" command enables sip switch for this virtual port.
NOTE
You can also specify the logical SIP port number 5060 or the keyword sip.
3. Configure a domain and specify a SIP domain name and dummy user.
ServerIronADX(config-vs-proxy-domain-1)# port sip sip-user-name sipuser
domain-name domain-1
Syntax: [no] port sip [sip-user-name <user-name> [domain-name <domain-name>]]
NOTE
The domain name is now optional. If you do not specify a domain name, the server IP address
is used.
4. Bind real SIP registrar servers.
ServerIronADX(config-vs-proxy-domain-1)# bind sip registrar-1 sip registrar-2
sip
Syntax: bind sip <registrar-name> bind sip <registrar-name> sip
5. Bind real SIP proxy servers.
ServerIronADX(config-vs-proxy-domain-1)# bind sip proxy-server-1 sip
proxy-server-2 sip
6. Return to global configuration mode.
ServerIronADX(config-vs-proxy-domain-1)# exit
Configuring health check
SIP Health Check can be performed by either the SIP REGISTER or OPTIONS method. Configure the
method according to your needs. The default method is REGISTER.
To configure SIP Health Check correctly, you must configure the sip-domain-name and dummy-user
at the virtual port level. SIP Health Check is only enabled at Layer 7 using UDP as the transport
layer.
