Server Load Balancing > Binding Same Real Ports to Multiple VIP Ports

Binding Same Real Ports to Multiple VIP Ports
This feature provides the ability to bind same real ports to multiple VIP ports. This is useful when you want to bind more than one VIP to the same application service on real servers, and these real servers are listening on different ports.
NOTE: To bind twice to the same real port, you must configure an alias port.
NOTE: This command is backward-compatible with the real-port command.
To bind multiple ports to one real server port, follow these steps:
1.
ServerIron(config)# server real rs1
ServerIron(config-rs-rs1)# port 81
ServerIron(config-rs-rs1)# port 8081 <- alias port
 
2.
ServerIron(config)# server real rs2
ServerIron(config-rs-rs2)# port 82
ServerIron(config-rs-rs2)# port 8082 <- alias port
 
3.
ServerIronADX(config)# server virtual-name-or-ip vs1
 
4.
ServerIronADX(config-vs-vs1)# port http
 
5.
ServerIronADX(config-vs-vs1)# bind http rs1 81 rs2 82
 
6.
ServerIronADX(config)# server virtual-name-or-ip vs2
ServerIronADX(config-vs-vs2)#port http
 
7.
ServerIronADX(config-vs-vs2)# bind http rs1 8081 real-port 81 rs2 8082 real-port 82
 
Syntax: bind <virtual-port> <real-server-name> <alias-port> [real-port <real-port-num>]
