HA Parameters

Defines the DiffServ value for HA Maintenance traffic flowing on the HA Maintenance interface.

The valid value is 0 (lowest priority or best-effort service) to 63 (highest priority). The default is 46.

Note: For the parameter to take effect, a device restart is required.

Defines the duration (in seconds) to delay the transition from HA non-operational state, which occurs during HA synchronization between active and redundant devices, to HA operational state. This feature may be useful, for example, to delay HA switchover when using switches with spanning tree protocol (STP) that take a long time until their ports (to which the redundant device is connected) is ready. In such a scenario, if this feature were not enabled (i.e., 0), after synchronization there would be no connectivity between the redundant device's network interface and the switch.

The valid value is 0 to 180. The default is 0.

Enables the device to send a SIP re-INVITE message with the local IP address of the new active device after a High-Availability (HA) switchover, for current calls. This allows the device to maintain the current calls from the active to redundant device (now active) after a switchover.

Note:

Specifies the MAC address of one of the two devices in the HA system.

For more information, see Quick-and-Easy Initial HA Configuration.

Note: When downloading an ini file from a device that is operating in HA mode, the parameter is the MAC address of the active device.

Specifies the MAC address of one of the two devices in the HA system.

For more information, see Quick-and-Easy Initial HA Configuration.

Note: When downloading an ini file from a device that is operating in HA mode, the parameter is the MAC address of the redundant device.

Defines a name for the active 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".

Note: When the device sends alarms to OVOC, this name is displayed at the beginning of the alarm description in OVOC, for example, "(SBCSITE01): Proxy lost. looking for another proxy". However, the name is not displayed for the alarms retrieved (from the device's Active Alarms table) when OVOC initially connects to the device.

Defines a name for the redundant device, which is displayed on the Home page to indicate the redundant device.

The valid value is a string of up to 128 characters. The default value is "Device 2".

Note: When the device sends alarms to OVOC, this name is displayed at the beginning of the alarm description in OVOC, for example, "(SBCSITE02): Proxy lost. looking for another proxy". However, the name is not displayed for the alarms retrieved (from the device's Active Alarms table) when OVOC initially connects to the device.

Defines the Maintenance interface address of the redundant device in the HA system.

By default, no value is defined.

Note: For the parameter to take effect, a device restart is required.

Enables HA switchover based on HA priority.

For more information on the HA switchover mechanism, see Device Switchover upon Failure.

Defines the priority of the active device used in the HA Preempt mechanism.

The valid value is 1 (lowest priority) to 10 (highest priority). The default is 5.

Note:

Defines the priority of the redundant device used in the HA Preempt mechanism.

The valid value is 1 (lowest priority) to 10 (highest priority). The default is 5.

Note:

Enables the HA Network Monitor feature, which checks connectivity with network destinations, using pings. When a user-defined number of destinations fail the connectivity test (see 'Network Monitor Threshold' parameter), an HA switchover occurs.
