Verifying System Failover Configuration

LYSH@MyHostName# configure
configure# failover show

Configuring System Failover

Note that if there the System Failover configuration already exists, it will overwrite.

LYSH@MyHostName# configure
configure# failover add 192.168.0.1/24 eth0 mykey 192.168.0.2 active 120
configure# failover show
vip=192.168.0.1/24
iface=eth0
secret=mykey
host=192.168.0.2
initmode=active
curmode=
curmode_dt=-
peermode=
peermode_dt=-
deadtime=120
state=disabled
last_error_msg=No error

Enabling System Failover

The System Failover does not work before enabling the System Failover.

LYSH@MyHostName# configure
configure# failover enable
configure# failover show
vip=192.168.0.1/24
iface=eth0
secret=mykey
host=192.168.0.2
initmode=active
curmode=
curmode_dt=-
peermode=
peermode_dt=-
deadtime=120
state=enabled
last_error_msg=No error

Disabling System Failover

To stop the System Failover, use the disable command. If you enable the System Failover after disabling it, the System Failover works again.

LYSH@MyHostName# configure
configure# failover disable
configure# failover show
vip=192.168.0.1/24
iface=eth0
secret=mykey
host=192.168.0.2
initmode=active
curmode=
curmode_dt=-
peermode=
peermode_dt=-
deadtime=120
state=disabled
last_error_msg=No error

Deleting System Failover configuration

Note that if you deleted it, the System Failover does not work before configuring it.

LYSH@MyHostName# configure
