The tasks under the first item (Configure SLB parameters on the Internet ServerIron) are described in the
following sections. The remaining tasks are identical to the tasks for configuring basic FWLB for Layer 3 firewalls.
For more information about these tasks, see “Configuring Basic Layer 3 FWLB” on page 4-1.
Configuring the SLB Parameters
In an SLB-to-FWLB configuration, all SLB configuration takes place on the Internet ServerIron. The ServerIron on
the private side of the firewalls does not contain any SLB configuration information. This section describes how to
configure the Internet ServerIron to provide SLB for the real servers and virtual server shown in Figure 8.1 on
page 8-2.
NOTE: This section describes basic SLB configuration tasks. For advanced configuration features, see the
ServerIron TrafficWorks Server Load Balancing Guide.
Configuring the Real Servers
To configure the real servers shown in Figure 8.1 on page 8-2, enter the following commands on the Internet
ServerIron (ServerIron A).
NOTE: In SLB-to-FWLB configurations, you must define the real servers as remote servers.
USING THE CLI
ServerIronA(config)# server remote-name RS1 192.168.2.50
ServerIronA(config-rs-RS1)# port http
ServerIronA(config-rs-RS1)# exit
ServerIronA(config)# server remote-name RS2 192.168.2.60
ServerIronA(config-rs-RS2)# port http
ServerIronA(config-rs-RS2)# exit
The server remote-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: If you use the server real-name command instead of the server remote-name command, the real
servers are added as local servers. Use the server remote-name command. You must add them as remote
servers for SLB-to-FWLB.
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 Check" chapter in the
ServerIron TrafficWorks Server Load Balancing Guide.
Configuring the Virtual Server
To configure the virtual server shown in Figure 8.1 on page 8-2, enter the following command on the Internet
ServerIron (ServerIron A).
USING THE CLI
ServerIronA(config)# server virtual-name www.brocade.com 192.168.1.2
ServerIronA(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>]
