Configuring the Real Servers
To configure the real servers shown in Figure 8.2 on page 8-3, enter the following commands on the internal
ServerIron (ServerIron B).
NOTE: In FWLB-to-SLB configurations, you must define the real servers as remote servers unless Proxy ARP is
enabled on the internal router.
USING THE CLI
ServerIronB(config)# server real-name RS1 192.168.2.50
ServerIronB(config-rs-RS1)# port http
ServerIronB(config-rs-RS1)# exit
ServerIronB(config)# server real-name RS2 192.168.2.60
ServerIronB(config-rs-RS2)# port http
ServerIronB(config-rs-RS2)# exit
The server real-name command adds a real server. The port command enables a TCP or UDP port on the
server. In this case, the port http command enables TCP port 80 (HTTP).
NOTE: You can use the server real-name command if Proxy ARP is enabled on the internal router. Otherwise,
you must use the server remote-name command to add the real servers instead of the server real-name
command.
Syntax: [no] server remote-name <text> <ip-addr>
Syntax: [no] port <port> [disable | enable]
Syntax: [no] port <port> [keepalive]
For information about the optional parameters with the port command, see the "Health Checks" chapter in the
ServerIron TrafficWorks Server Load Balancing Guide.
Configuring the Virtual Server
To configure the virtual server shown in Figure 8.2 on page 8-3, enter the following command on the internal
ServerIron (ServerIron B).
USING THE CLI
ServerIronB(config)# server virtual-name www.brocade.com 192.168.1.2
ServerIronB(config-vs-www.brocade.com)# port http
The server virtual-name command adds the virtual server. The port command enables a TCP or UDP port on
the server.
Syntax: [no] server virtual-name <text> [<ip-addr>]
Binding the Real Server to the Virtual Server
To bind the real servers to the virtual server, enter the following commands on the internal ServerIron
(ServerIron B). Notice that the port binding takes place on the Virtual Server configuration level.
USING THE CLI
ServerIronB(config)# server virtual www.foundrynet.com
ServerIronB(config-vs-www.brocade.com)# bind http RS1 http
ServerIronB(config-vs-www.brocade.com)# bind http RS2 http
ServerIronB(config-vs-www.brocade.com)# exit
Syntax: [no] bind <port> <real server name> <port>
Enabling FWLB-to-SLB
To enable FWLB-to-SLB, enter the following command on the internal ServerIron (ServerIron B).
