11.7. HA Advanced Settings
The following cOS Core advanced settings are available for High Availability:
Sync Buffer Size
How much sync data, in Kbytes, to buffer while waiting for acknowledgments from the cluster
peer.
Default: 1024
Sync Packet Max Burst
The maximum number of state sync packets to send in a burst.
Default: 20
Initial Silence
The time in seconds to stay silent on startup or after reconfiguration. When the active unit in an
HA cluster believes the inactive unit is no longer reachable, it continues to send synchronization
traffic normally for a period of one minute in the expectation that the inactive unit will again
become reachable. In order not to flood the network unnecessarily, after one minute has
elapsed, the synchronization traffic is then only sent after repeated periods of silence. The length
of this silence is this setting.
Default: 5
Use Unique Shared Mac
Use a unique shared MAC address for each interface. For further explanation of this setting see
Section 11.3.5, “Unique Shared Mac Addresses”.
Default: Enabled
Deactivate Before Reconf
If enabled, this setting will make an active node failover to the inactive node before a reconfigure
takes place instead of relying on the inactive node detecting that the active node is not
operating normally and then taking over on its own initiative. Enabling this setting shortens the
time where no node is active during configuration deployments.
Default: Enabled
Reconf Failover Time
Number of non-responsive seconds before failover at HA reconfiguration. The default value of
zero means immediate reconfiguration.
Default: 0
