Configuring HA active-active FWLB

DRAFT: BROCADE CONFIDENTIAL

Configuring the management IP address and default gateway

You must add a management IP address to the ServerIron ADX and the IP address must be in the

same sub-net as the ServerIron ADX’s interfaces with the Layer 3 firewalls.

For the default gateway address, specify the IP address on the router’s interface with the

ServerIron ADX.

ServerIronADX(config)# ip address 10.10.1.111 255.255.255.0

ServerIronADX(config)# ip default-gateway 10.10.1.101

Syntax: ip address <ip-addr> <ip-mask>

Syntax: ip address <ip-addr>/<mask-bits>

Syntax: ip default-gateway <ip-addr>

Configuring the firewall port

When you configure the ServerIron ADX for IronClad FWLB, you must specify the port number of the

dedicated synchronization link between the ServerIron ADX and its active-active partner. To specify

the port, enter a command such as the following at the global CLI level.

ServerIronADX(config)# server fw-port 4/13

Syntax: [no] server fw-port <portnum>

If the link between the two ServerIron ADXs 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.

Configure firewall group parameters

Change the load balancing method from least connections to least connections per application

(optional)
