If there is more than one switch in the switch stack, and you enter the reload slot stack-member-number command, you are not prompted to save the configuration. be aware of this if you reload the active member using the slot option 0. In Cisco IOS, whenever you enter a configuration command it takes effect immediately and goes into the 'running configuration'. When the router boots up it loads the 'startup configuration'. To make your changes persistent over a reboot you need to copy the running configuration to the startup configuration with the 'copy run start command'. You can use the reload at command to schedule a reboot of the whole stack but there is no way that I'm aware of to reload an individual stack member at a specific time, without resorting to third-party tools to issue the reload slot command at a specific time. The command is “ip route profile” in global configuration mode. This feature can be disabled with the command “no ip route profile” in global configuration mode. Routing table change statistics can be viewed with the “show ip route profile” command in exec mode. Reference: CSCdi76662: ipc-console slot-num privileged exec.

A system restart on Cisco routers is called a reload. If the router needs to be reloaded for any reason, the reload command needs to be entered from privileged mode, as shown in Example 4-4. The reload command also allows a time to be set so that the system restarts after the specified time expires.

Example 4-4 System Reload Options

The system can also be reloaded by switching it off and then back on again.

The configuration register is used to specify the router's behavior during the reloading process. It determines whether the IOS image should be loaded, determines whether terminal access parameters are provided, and enables or disables the Esc key. The configuration register can be modified in configuration mode using the config-register command.

CAUTION

Use the config-register command only if you completely understand its effects. Incorrect use of this command can make the system inaccessible.

By default, the router first tries to boot from the first image in the onboard system Flash, if available, and then it tries the PCMCIA Flash cards. The user may also specify which images or locations to attempt booting from and the order using the boot system command in configuration mode:

This causes the system to attempt booting from an image in the Flash memory in PCMCIA slot 0 before going to the onboard system Flash.

To upgrade the Cisco IOS software version running on a router, you must first determine the right image to upgrade to using the upgrade planners available on http://www.cisco.com.

CAUTION

Attempting to load an incorrect image for your system might leave the system inaccessible. Ensure that you have the correct software image and meet the RAM and Flash memory requirements to run and store the image before installing.

The copy command copies an image into Flash memory. There are many ways to do this, as demonstrated in Example 4-5.

Example 4-5 Options for Copying an IOS Image into Flash Memory

The most common methods are TFTP and FTP. After the file has been placed on your TFTP or FTP server, enter the copy command from privileged mode and answer the questions on server IP address and source and destination filenames. After you specify which image the system should load using the boot system command, a reload is required for the new version of IOS to be booted.
