54.3.5 HA Ping Parameters
The High Availability (HA) Ping parameters are described in the table below.
Table 54-21: HA Ping Parameters
Parameter Description
HA Device Name
configure system >
high-availability >
unit-id-name
[HAUnitIdName]
Defines a name for the device, which is displayed on the Home page to
indicate the active device.
The valid value is a string of up to 128 characters. The default value is
"Device 1" for the active device and "Device 2" for the redundant device.
HA Remote Address
configure system >
high-availability >
remote-address
[HARemoteAddress]
Defines the Maintenance interface address of the redundant device in
the HA system.
By default, no value is defined.
HA Revertive
configure system >
high-availability >
revertive-mode
[HARevertiveEnabled]
Enables HA switchover based on HA priority.

[0] Disable (default) = A switchover over to the redundant device is
done only if a failure occurs in the currently active device.

[1] Enable = A switchover over to the redundant device is done if a
failure occurs in the currently active device. However, a switchover to
the device with the highest priority (configured by the HAPriority
parameter) occurs whenever the device recovers from a failure.
Therefore, whenever possible, the highest priority device is the active
one.
For more information on the HA switchover mechansim, see Device
Switchover upon Failure on page 524.
HA Priority
configure system >
high-availability >
priority
[HAPriority]
Defines the priority of the device used in the HA Revertive mechanism.
The valid value is 1 (lowest priority) to 10 (highest priority). The default is
5.
Note:

The parameter is applicable only if you configure the 'HA Revertive'
parameter to
Enable .

You must configure each device in the HA system with different
parameter values (priorities).
HA Monitoring Parameters

reply is received from a ping and the previous ping was successful, a
switchover occurs to the redundant device.

[0] Disabled (default)

[1] Enabled
Web: HA Network
Reachability Destination
Address
[HAPingDestination]
Defines the IP address of the destination that the device pings.
The default is 0.0.0.0.

Reachability Source
Interface Name
