Chapter 3 Initial Configuration

Configuring CPU Switch Module Redundancy

Forcing a Switchover from ROM Monitor Mode

You can manually force the standby CPU switch module to take over as the active CPU switch module ROM monitor mode. To force a switchover from ROM monitor mode, enter the following commands on the active CPU switch module CLI:

Command

switchover

Purpose

Causes a CPU switch module reset and switchover. The CPU switch module stays in ROM monitor mode.

Note Using the reset command in ROM monitor mode on the active processor CLI under normal conditions does not cause a switchover.

Example

The following example shows how to manually cause a CPU switch module switchover from ROM monitor mode:
