admin redundancy command descriptions

cpm-switchover

Syntax

  • cpm-switchover [now]

Context

  • [Tree] admin redundancy cpm-switchover

Description

This command triggers a controlled CPM switchover.

Parameters

now
Keyword to perform the CPM switchover without requesting confirmation.

mc-master-lock

Syntax

  • [no] mc-master-lock

Context

  • [Tree] admin redundancy mc-master-lock

Description

This command locks the gateway in the active operational role when ICR or geo-redundancy is deployed. The gateway remains in the active operational role regardless of any ICR active/standby election criteria that may occur.

The no form of this command unlocks and restores the use of normal ICR active/standby election criteria.

Note: When enabled, the manual switchover command (admin redundancy mc-mobile-switchover mobile-gateway) is also locked. An error is returned if a manual switchover is attempted while the mc-master-lock command is enabled.
WARNING: In an active/active case, the command must only be executed on one node. If executed on both nodes, the multi-chassis synchronization (MCS) synchronization fails and an alarm is issued.

Default

no mc-master-lock

mc-mobile-switchover

Syntax

  • mc-mobile-switchover mobile-gateway gw-id peer ip-address [{reboot | now}] [abort]

Context

  • [Tree] admin redundancy mc-mobile-switchover

Description

This command issues a manual switchover to transition the active gateway to a standby role and its peer gateway to the active role. The manual switchover is not hitless, but synchronizes the complete charging information and state for each bearer, enabling the standby system to transition with minimal disruption and data loss.

Parameters

gw-id
Specifies the gateway ID.
Values: 1 to 8
ip-address
Specifies the peer IP address for the manual switchover.
Values: ip-address | ipv6-address
reboot
Keyword to reboot the node after mc-mobile switchover.
now
Keyword to force the switchover without full reconciliation. If the ICR is in the up state, the manual switchover can be performed even when the synchronization state is not hot.
WARNING: If the now keyword is specified, the switchover is executed, but the new active node may have incomplete UE records. In some cases this can be service impacting.
abort
Keyword to abort an in-progress mc-mobile switchover. This keyword can only be specified for an ongoing switchover that is in progress for at least five minutes. The user must respond to a confirmation request to proceed. If "yes" is specified, the system issues a disconnect to the standby system, makes it active, switches the active to the standby state, and activates the MC redirect tunnel.

mc-slave-lock

Syntax

  • [no] mc-slave-lock

Context

  • [Tree] admin redundancy mc-slave-lock

Description

This command locks the gateway in the standby operational role when ICR or geo-redundancy is deployed. The gateway remains in the standby operational role regardless of any ICR active/standby election criteria that may occur.

The no form of this command unlocks and restores the use of normal ICR active/standby election criteria.

Note: When enabled, the manual switchover command (admin redundancy mc-mobile-switchover mobile-gateway) is also locked. An error is returned if a manual switchover is attempted while the mc-slave-lock command is enabled.

Default

no mc-slave-lock

mg-switchover

Syntax

  • mg-switchover

Context

  • [Tree] admin redundancy mg-switchover

Description

Commands in this context perform a controlled SM-VM switchover.

group

Syntax

  • group mg-group-id [now] [max-preparation-time max-preparation-time]

Context

  • [Tree] admin redundancy mg-switchover group

Description

This command triggers an SM-VM controlled switchover.

Parameters

mg-group-id
Specifies the MG group ID for which to perform the controlled switchover.
Values: 1 to 15
now
Keyword to perform the controlled switchover without requesting confirmation.
max-preparation-time
Specifies the waiting time, in seconds, that the SM-VM uses to process all charging data before the standby SM-VM becomes active. When set to 0, the switchover proceeds without a maximum preparation time, until all charging data has been processed.
Note: Incoming control messages are not served during the preparation phase defined by the max-preparation-time parameter.
Values: 0 (disabled) to 60
Default: 5
