cluster-config
Use cluster-config to manage basic SLB interaction with clustered SBCs.
Constraints
Only systems with SLB configured support cluster-config.
Parameters
The cluster-config configuration element contains the following parameters:

-
Enter the log level.
- Default: CRITICAL
- Values: ZERO | NONE | EMERGENCY | CRITICAL | MAJOR | MINOR | WARNING | NOTICE | INFO | TRACE | DEBUG | DETAIL

-
Enable or disable the automatic rebalancing of the cluster when a new SBC becomes available.
- Default: enabled
- Values: enabled | disabled
- source-rebalance-threshold
-
Enter the percentage of advertised registration capacity an SBC must be above to be considered a source of rebalanced endpoints.
- Default: 50
- Min: 0 | Max: 100
- dest-rebalance-threshold
-
Enter the percentage of advertised registration capacity an SBC must be below to be considered a destination of rebalanced endpoints.

- Default: 500
- Valid value: 0
- Min: 50 | Max: 4294967295
- session-multiplier
-
Enter a factor that when multiplied by an SBC's licensed session limit, determines the maximum number of endpoints that the SBC can support (that is, its maximum occupancy).
- Default: 10
- Min: 1 | Max: 100
- atom-limit-divisor
-
Enter a factor of contacts to endpoints that can be used in occupancy and occupancy rate calculations.
- Default: 1
- Min: 0 | Max: 4294967295
- rebalance-skip-ahead
-
Restrict the target set of SBCs eligible for rebalancing to those whose re-registration is not scheduled within the number of milliseconds specified by this parameter.
- Default: 0
- Min: 0 | Max: 4294967295
- rebalance-max-refresh
-
Restrict the target set of SBCs eligible for rebalancing to those whose re-registration is not scheduled until after the number of milliseconds specified by the parameter.
- Default: 0
- Min: 0 | Max: 4294967295
- ignore-tgt-svcs-on-rebalance
-
Not currently supported.
- Default: disabled
- Values: enabled | disabled
- rebalance-del-app-entries
-
Set to enabled to remove cached registration entries after the rebalance operation completes.
- Default: enabled
- Values: enabled | disabled
- inactive-sd-limit
-
Enter the maximum silent interval in seconds before the SLB flags the SBC as dead and removes it from the cluster.
- Default: 1800
- Min: 0 | Max: 31536000
- red-port
-
Enter the port to listen on for redundancy flow sync messages.
- Default: 2001
- Valid value: 0

Enter the maximum number of redundancy sync transactions to keep alive.
- Default: 10000
- Min: 0 | Max: 50000
- red-sync-start-time
-
The maximum period of time (in milliseconds) that the standby SBC waits for a heartbeat signal from the active SBC before assuming the active role.
- Default: 5000
- Min: 0 | Max: 4294967295
- red-sync-comp-time
-
The interval between synchronization attempts after the completion of a redundancy check.
- Default: 1000
- Min: 0 | Max: 4294967295
- service-ports
-
Access the service-ports subelement.
