Processor Card Redundancy Commands
Processor card redundancy provides protection against processor card failure. Use the following commands to configure and monitor processor card redundancy operations.
auto-sync counters interface
To enable automatic synchronizing of traffic statistics, performance monitoring counters, and performance history counters on the active processor card to the standby processor card, use the auto-sync counters interface command. To disable automatic synchronizing of traffic statistics and performance monitoring counters, use the no form of this command.

Command History
This table includes the following release-specific history entries:
12.2(24)SV
This command was introduced.
12.2(29)SV

•
Startup configuration
•
•
Examples
The following example shows how to disable automatic synchronizing of the traffic statistics and performance monitoring counters.
Switch#configure terminalSwitch(config)# redundancySwitch(config-red)# no auto-sync counters interfaceRelated Commands
auto-sync running-config
To selectively enable only automatic synchronizing of the running configuration on the active processor to the standby processor card, use the auto-sync running-config command. To disable automatic synchronizing of the running configuration, use the no form of this command.

•
•
•
Usage Guidelines
Use this command to enable or disable automatic synchronizing of the running configuration without affecting the following types of synchronization:
•
•
When a processor card switchover occurs, the standby processor card normally uses the running configuration rather than the startup configuration. However, if auto-sync running-config is disabled when a processor card switchover occurs, the standby processor card uses the startup configuration.
In maintenance mode, all database synchronizing to the standby processor card is disabled even if auto-sync running-config is enabled.
Examples
The following example shows how to disable automatic synchronizing of the running configuration.
Switch#configure terminalSwitch(config)# redundancySwitch(config-red)# no auto-sync running-configRelated Commands
auto-sync startup-config
To selectively enable only automatic synchronizing of the startup configuration to the standby processor card, use the auto-sync startup-config command. To disable automatic synchronizing of the startup configuration, use the no form of this command.

Examples
The following example shows how to clear the redundancy history log.
Switch# clear redundancy historyRelated Commands

Syntax Description
This command has no other arguments or keywords.
Defaults
Disabled
Command Modes
Redundancy configuration
Command History
This table includes the following release-specific history entries:
•
•
•
Usage Guidelines
In maintenance mode, the active processor card does not automatically synchronize information to the standby processor card. No standby processor card errors and alarms are reported to the active processor card. The standby processor card leaves the hot-standby mode, enters the negotiation state, and transitions to the cold-standby state.
When maintenance mode is disabled, the standby processor card reloads until it reaches the hot-standby state.
Maintenance mode is useful for processor card maintenance operations and system image troubleshooting.
Note
Examples
The following example shows how to enable maintenance mode redundancy.
Switch# configure terminalSwitch(config)# redundancySwitch(config-red)# maintenance-modeThis command will place the system in SIMPLEX mode [confirm] yRelated Commands
Enters redundancy configuration mode.
Displays processor card redundancy status and configuration information.

redundancy manual-sync
To cause an immediate one-time database update of the specified database information, use the redundancy manual-sync command.
redundancy manual-sync {running-config | startup-config | both}
Syntax Description
Defaults
None
Command Modes
Privileged EXEC
Command History
This table includes the following release-specific history entries:
•
•
•
Usage Guidelines
This command is not usually required because automatic synchronization is enabled by default and, upon exiting global configuration mode, the running configuration is updated on the standby processor card. (Exit global configuration mode by entering Ctrl-Z or end.) The startup configuration is updated when the copy command is issued.
If auto-synchronizing is disabled, the redundancy manual-sync command updates the standby processor database information to be identical with the active processor card.
If the system is unable to complete the update, an error message is displayed.
This command is only allowed on the active processor card.
Examples
The following example shows how to make the active processor card send an update for both the running configuration and the startup configuration to the standby processor card.
Switch# redundancy manual-sync bothRelated Commands
redundancy reload peer
To reload the standby processor card, use the redundancy reload peer command.
redundancy reload peer
Syntax Description
This command has no other arguments or keywords.
Defaults
None
Command Modes
Privileged EXEC
Command History
This table includes the following release-specific history entries:
•
•
•
Usage Guidelines
Use this command to reload the standby (or peer) processor card.
The active processor card is allowed to reload a standby processor card that is fully running the Cisco IOS software by using an NMI (non-maskable interrupt).
This command will not succeed on the active processor card if the standby processor card has not fully loaded its system IOS image and reached the hot-standby state.
This command cannot be entered on the standby processor card.
Examples
The following example shows how to reload the standby processor card.
Switch#redundancy reload peerReload peer [confirm] yPreparing to reload peerRelated Commands

redundancy switch-activity
To manually switch activity from the active processor card to the standby processor card, use the redundancy switch-activity command.
redundancy switch-activity [force]
Syntax Description
force
Forces a switch of activity even when the standby processor card has not reached the hot-standby state, or if some other software condition is preventing a normal switchover from occurring.
Defaults
The active processor card switches over only if the standby processor card has reached hot-standby mode.
Command Modes
Privileged EXEC
Command History
This table includes the following release-specific history entries:
•
•
•
Usage Guidelines
This command must be issued on the active processor card. It takes effect if the processor card is in a state to allow switchover; that is, the standby processor card is in the "Standby Hot" state and platform software is not temporarily disallowing the switchover.
Examples
The following example shows how to switch activity to the standby processor card.
Switch#redundancy switch-activityPreparing to switch activityThis will reload the active unit and force a switch of activity [confirm] y01:40:35: %SYS-5-RELOAD: Reload requestedRelated Commands
