# Configuration

Device > Configure > Redundancy Framework Subsystem > Configuration

From this dialog box, you can configure the settings for the Redundancy Framework subsystem.

The following information is displayed:

- Redundancy Mode (cRFCfgRedundancyMode)

- Redundancy Mode Descr (cRFCfgRedundancyModeDescr)

- Maintenance Mode (cRFCfgMaintenanceMode)

- Notifications Enabled (cRFCfgNotifsEnabled)

- Admin Action Command (cRFCfgAdminAction)

The following list specifies buttons in this dialog box, as well as their function:

- Click OK to continue.

- Click Apply to save the changes in the dialog box.

- Click Cancel to close the dialog box.

- Click Refresh to update the contents of the dialog box.

- Click Print to print the contents of the dialog box.

- Click Help to access online help.

Redundancy Mode (cRFCfgRedundancyMode)

Indicates the redundancy type currently in effect.

Redundancy Mode Descr (cRFCfgRedundancyModeDescr)

Further describes the redundancy mode indicated by cRFCfgRedundancyMode. Implementation-specific terminology associated with the current redundancy mode may be presented here.

Maintenance Mode (cRFCfgMaintenanceMode)

Indicates whether redundant units can exchange synchronization messages with each other:

- When the value of this object is "true", the redundant system is considered to be in a maintenance mode of operation. When the value of this object is "false", the redundant system is considered to be in a normal (non-maintenance) mode of operation.

- In maintenance mode, the active unit does not communicate with the standby unit, and standby unit progression does not occur. When maintenance mode is disabled, the standby unit is reset to recover.

Notifications Enabled (cRFCfgNotifsEnabled)

Allows the enabling/disabling of Redundancy Framework subsystem notifications.

Admin Action Command (cRFCfgAdminAction)

Used to launch Redundancy Framework subsystem action commands. The commands are useful for maintenance and software upgrade activities.

Timers

The following information is displayed:

- Keepalive Threshold (cRFCfgKeepaliveThresh)

- Keepalive Timer (milliseconds) (cRFCfgKeepaliveTimer)

- RF Notification Timer (milliseconds) (cRFCfgNotifTimer)

Keepalive Threshold (cRFCfgKeepaliveThresh)

On platforms that support keep-alives, this object designates the number of lost keep-alives tolerated before a failure condition is declared. If this occurs, a SWACT notification is sent.

Note: This value is not applicable for platforms that do not support keep-alives.

Keepalive Timer (milliseconds) (cRFCfgKeepaliveTimer)

The value of this object is used to guard against lost keep-alives. The Redundancy Framework subsystem expects to receive a keep-alive within this period. If a keep-alive is not received within this time period, a SWACT notification is sent.

Note: This value is not applicable for platforms that do not support keep-alives.

RF Notification Timer (milliseconds) (cRFCfgNotifTimer)

As the standby unit progresses to the "standbyHot" state, asynchronous messages are sent from the active unit to the standby unit. These messages must then be acknowledged by the standby unit. If the active unit receives acknowledgement during the time period specified by this object, progression proceeds as normal. If the timer expires and an acknowledgement is not received by the active unit, a switch of activity occurs.

Note: The term "notification" refers to a Redundancy Framework notification, not an SNMP notification.
