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
Use the fw-vrrpe-priority command in the fw-group configuration mode.
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.
