Configuring HA FWLB
May 31, 2012 © 2012 Brocade Communications Systems, Inc. 5 - 7
ServerIron(config)# ip address 10.10.1.111 255.255.255.0
ServerIron(config)# ip default-gateway 10.10.1.101
Syntax: ip address <ip-addr> <ip-mask>
or
Syntax: ip address <ip-addr>/<mask-bits>
Syntax: ip default-gateway <ip-addr>
Configuring the Partner Port
When you configure the ServerIron for IronClad FWLB, you need to specify the port number of the dedicated
synchronization link between the ServerIron and its active-active partner. To specify the port, enter a command
such as the following at the global CLI level:
ServerIron(config)# server fw-port 4/13
Syntax: [no] server fw-port <portnum>
If the link between the two ServerIrons is a trunk group (recommended for added redundancy), specify the port
number of the primary port. The primary port is the first port in the trunk group.
Configuring the Additional Data Link (the Always-Active Link)
The default port-based VLAN, VLAN 1, contains all the ServerIron ports by default. In configurations such as the
one shown in Figure 5.1 on page 5-5, the ports of the additional data link between the ServerIrons in each pair
also are in this VLAN. For this type of configuration, you must perform the following configuration steps for the
default VLAN:
• Disable the Spanning Tree Protocol (STP)
• Enable the always-active option
To disable STP and enable the always-active feature, enter the following commands:
ServerIron(config)# vlan 1
ServerIron(config-vlan-1)# no spanning-tree
ServerIron(config-vlan-1)# always-active
ServerIron(config-vlan-1)# exit
ServerIron(config)#
Syntax: [no] vlan <num>
Syntax: [no] spanning-tree
Syntax: [no] always-active
NOTE: To use the always-active feature, you also must enable the L2-fwall feature at the firewall group
configuration level.
Configuring the Router Port
High-availability FWLB configurations require that you identify the ports on the ServerIron that are attached to the
router(s).
To identify the router port, enter a command such as the following:
ServerIron(config)# server router-ports 4/12
Syntax: [no] server router-ports <portnum>
