Firewall load balancing enhancements

1

Syntax: [no] client-max-conn-limit <name>

Enter the name of the max connection policy for <name>.

NOTE

When the policy is bound to a VIP, the policy limits the number of connections that a client can have
on any real server on the network.

Firewall load balancing enhancements

This section contains the following sections:

“Enabling firewall strict forwarding”

“Enabling firewall VRRPE priority”

“Enabling track firewall group”

“Enabling firewall session sync delay”

Enabling firewall strict forwarding

To enable load balancing only when traffic is going to a firewall, use the following command.

ServerIronADX(config)# server fw-strict-fwd

Syntax: server fw-strict-fwd

Use the server fw-strict-fwd command in the global configuration mode. Without this command,
when the ServerIron receives traffic that matches the firewall flow session and the traffic is not
received from a firewall, then the ServerIron assumes that it needs to be load balanced to a
firewall.

This command checks to ensure that traffic is going to a firewall and only then does the ServerIron
load balance it to a firewall.

Enabling firewall VRRPE priority

To configure VRRPE state to track the firewall group state, use the following command.

ServerIronADX(config)# server fw-g 2

ServerIronADX(config-tc-2)#fw-vrrpe-priority

ServerIronADX(config-tc-2)#

Syntax: fw-vrrpe-priority <priority>

Use the fw-vrrpe-priority command in the fw-group configuration mode. <priority > is the VRRPE
priority associated with current firewall group state. Valid values are 1 to 255.

NOTE

This command can be used with the track-fw-group command below to force VRRPE state to track
the firewall group state for a specific vrid.
