gbcast <2-100>
This command displays the present Gratuitous Broadcast (gbcast) value and allows you
to change it. The gbcast value sets the interval between GARP messages that are sent by
the active master to ensure that all end-hosts have the correct MAC address/IP address
mapping. Increasing the gbcast value cuts down on the gbcast traffic, but lengthens the
interval between end-host ARP cache updates.
The gbcast value is multiplied by the /cfg/net/vrrp/adint value to determine the interval
in seconds between GARP messages. For example, if your adint value is 10 and your
gbcast value is 3, the interval between GARP messages will be 30 (10 x 3) seconds. The
default gbcast value is 2.
afc y|n
This command is used to enable (
y
) or disable (
n
) Advanced Failover Checking (AFC).
When AFC is enabled, the system ARPs before initiating a failover caused by missed
VRRP advertisements.
prefmaster
This command allows you to specify which Switched Firewall in the cluster is the VRRP
Master. The preferred master always remains active when it has equal or better priority.
It goes into backup mode only when its links are down and regains its position once the
links are up.
