Constraints

Only systems with SLB configured support cluster-config.

Parameters

The cluster-config configuration element contains the following parameters:

state

Enable or disable the cluster configuration.

• Default: enabled
• Values: enabled | disabled

log-level

Enter the log level.

• Default: CRITICAL
• Values: ZERO | NONE | EMERGENCY | CRITICAL | MAJOR | MINOR | WARNING | NOTICE | INFO | TRACE | DEBUG | DETAIL

auto-rebalance

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: 0
• Min: 0 | Max: 4294967295

dest-rebalance-max

Enter the maximum occupancy rate that the SLB transfers to the new cluster member during a rebalance operation.

• Default: 80
• Min: 0 | Max: 100

tunnel-check-interval

Enter the interval in milliseconds between SLB tunnel audits.

• Default: 15000
• Min: 0 | Max: 4294967295

During a tunnel audit, the SLB checks the status of each tunnel and removes all tunnels flagged as dead.

tunnel-fail-interval

Enter the interval in milliseconds between periodic keepalive messages sent from a clustered SBC to the SLB.

rebalance-request-delay

Enter the interval in milliseconds between endpoint request messages sent from the SLB to a clustered SBC.

• 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
• Min: 1025 | Max: 65535

red-max-trans

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.

Path
