Chapter 3 Initial Configuration

Configuring CPU Switch Module Redundancy

Configuring Maintenance Mode

You can configure the Cisco ONS 15530 to enter the redundancy maintenance mode. Configuration synchronizations and standby CPU switch module fault reporting are suppressed in maintenance mode. Upon exiting maintenance mode and reverting to redundant mode, the standby switch CPU switch module reboots to the hot-standby state.

Note When the system is in maintenance mode, switchovers only occur by entering the redundancy switch-activity force command, or physically removing the active CPU switch module.

To configure maintenance mode, perform the following steps, beginning in global configuration mode:

	Command	Purpose
Step 1
	Switch(config)# redundancy	Enters redundancy configuration mode.
	Switch(config-red)#
Step 2
	Switch(config-red)# maintenance-mode	Configures the system in maintenance mode.

Example

The following example shows how to configure redundancy maintenance mode:

Switch(config)# redundancy

Switch(config-red)# maintenance-mode

This command will place the system in SIMPLEX mode [confirm] y

Displaying the CPU Switch Module Redundancy Configuration and Status

To display the CPU switch module redundancy configuration and status, use the following privileged EXEC commands:

Command	Purpose
show redundancy summary	Displays the redundancy configuration and status.
show redundancy capability	Displays capabilities of the active and standby CPU
	switch modules and the software version that is
	running.
show redundancy running-config-file	Displays the running configuration file on the standby
	CPU switch module.
	Note This command is only available on a terminal
	connected to the standby CPU switch module.
