[no] device-ha2 srv-monitor
Enables or disables (no) service monitoring. When enabled, the passive
Zyxel Device takes over when a monitored service daemon on the active
Zyxel Device fails.
[no] device-ha2 connchk-monitor
Enables or disables (no) connection check monitoring. When enabled, the
passive Zyxel Device takes over when a monitored interface on the active
Zyxel Device fails.
device-ha2 failover connchk-hold-
time <60..86400>
Sets a minimum time period between failovers to mitigate failover flapping.
Failover flapping occurs when the active and passive devices keep
switching due for example to a faulty up-link connection.
device-ha2 heartbeat period <1..10>
fail-tolerance <1..10>
Sets when failover is activated on the passive Zyxel Device. Zyxel Device will
change to active mode if it doesn’t receive a heartbeat after heartbeat
period x fail-tolerance seconds.
heartbeat period: the number of seconds (1-10) allowed for absence of
a heartbeat signal.
fail-tolerance: the number of heartbeat failures allowed.
device-ha2 license-sync
serial_number
Sets the serial number of the Zyxel Device (active or passive) with the
Device HA Pro subscribed license.
device-ha2 virtual-mac
zynos_style_mac_address
Specifies the Virtual MAC address of a port on the active Zyxel Device.
Virtual MAC is a shared MAC address which is owned by the active Zyxel
Device. All traffic can communicate with this shared MAC address, allowing
the backup Zyxel Device to pick up traffic seamlessly.
zynos_style_mac_address: The first (wan0) MAC address of the Zyxel
Device. A Zyxel-style MAC address must use the Zyxel OUI (Organizationally
Unique Identifier) such as 00-13-49-XX-XX-XX.
device-ha2 failover-count <5 ..50>
Sets the maximum number of times a Zyxel Device can change from active
to passive mode. The Zyxel Device won’t change to passive mode if it’s
already changed to passive mode failover-count times. This is to prevent
too many changes between active and passive mode.
device-ha2 failover reset-interval
<1..30>
Sets the time period after which the failover counter can be reset (1-30
days). The default is 5 days. For example, if the failover-count is 5 and
the
failover reset-interval is 30, then Zyxel Device can change
from active to passive mode at most 5 times within 30 days.
device-ha2 ap-firmware-sync
Sets the active device to upload the latest AP firmware to the passive
device after the active device discovers and downloads the latest AP
firmware from the cloud server.
device-ha2 firmware-update check-
timeout
Sets how long the active device will wait for a reply ping from the passive
device indicating it has fully rebooted.
check-timeout
: 1 - 3,600 seconds with 1,800 as the current default
device-ha2 firmware-update delay
Sets how long the active device will wait before updating its firmware after
receiving a reply ping from the passive device.
delay time: 1 - 300 seconds with 10 as the current default
show device-ha2 activation
Displays whether or not Device HA Pro is activated.
show device-ha2 mode
Displays whether this Zyxel Device is the active or passive device.
HA mode: Active | Passive.
show device-ha2 device-status
Displays if this Zyxel Device is active or passive, heartbeat link status, this
Zyxel Device serial number, Virtual MAC address and synchronization
progress.
show device-ha2 passive device-
status
Displays the passive Zyxel Device heartbeat link status, the passive Zyxel
Device serial number, Virtual MAC address and synchronization progress.
