Enabling High Availability Features

Disabling SLCR

	To disable the Cisco 7500 Single Line Card Reload feature, use the no service single-slot-reload-enable
	global configuration command on the Cisco 7500 series router.

Command		Purpose

Router(config)# no service single-slot-reload-enable		Disables single line card reloading for all of the line cards in the
		Cisco 7500 series router.

Verifying Cisco 7500 SLCR

Use the show running-configcommand to verify that single line card reloading has been successfully enabled on the Cisco 7500 series router. If the service single-slot-reload-enableline appears in the command output, Cisco 7500 SLCR is enabled. If this line does not appear in the command output, Cisco 7500 SLCR is disabled.

SLCR Configuration Example

In the following example, SLCR is enabled for all lines cards in the Cisco 7500 series router:

Router(config)# service single-slot-reload-enable

In the following example, SLCR is disabled for all line cards in the Cisco 7500 series router:

Router(config)# no service single-slot-reload-enable

SLCR Troubleshooting Tips

The debug oir command is used to debug the online insertion and removal (OIR) feature (which is also known as hot-swapping or power-on servicing). The debug oir command is often useful in debugging problems related to OIR, including single line card reloading.

RPR, RPR+, SSO, and FSU Troubleshooting Tips

Use the commands in the table below to troubleshoot the RPR, RPR+, SSO, and FSU features on Cisco 7500 series routers:

Command	Purpose

Router# show diag	Displays hardware information for the router.

Router# show redundancy	Displays the redundancy mode of the RSP. This command also
	displays information about the number of switchovers, system
	uptime, RSP uptime, and reasons for any switchovers.

Router# show version	Displays image information for each RSP.
