Chapter 4 Performing Switch Setup Configuration
How to Perform Switch Setup Configuration
You have these reload options:
• Software reload to take effect in the specified minutes or hours and minutes. The reload must take
place within approximately 24 days. You can specify the reason for the reload i n a string up to 255
characters in length.
• Software reload to take place at the specified time (using a 24-hour clock). If you spe cify the month
and day, the reload is scheduled to take place at the specified time and date. If you do not specify
the month and day, the reload takes place at the specified time on the current day (if the specified
time is later than the current time) or on the next day (if the specified time is earlier than the current
time). Specifying 00:00 schedules the reload for midnight.
The reload command halts the system. If the system is not set to manually boot up, it reboots itself.
If your switch is configured for manual booting, do not reload it from a virtual terminal. This restriction
prevents the switch from entering the boot loader mode and thereby taking it from the remote user’s
control.
If you modify your configuration file, the switch prompts you to save the configuration before reloading.
During the save operation, the system requests whether you want to pr oceed with the save if the
CONFIG_FILE environment variable points to a startup configuration file that no longer exists. If you
proceed in this situation, the system enters setup mode upon reload.
To cancel a previously scheduled reload, use the reload cancel privileged EXEC command.
How to Perform Switch Setup Configuration
Using DHCP to download a new image and a new configuration to a switch requires that you con figure
at least two switches. One switch acts as a DHCP and TFTP server and the second switch (client) is
configured to download either a new configuration file or a new configuration file and a new image file.

Configuring DHCP Autoconfiguration (Only Configuration File)

This task describes how to configure DHCP autoconfiguration of the TFTP and DHCP settings on a new
switch to download a new configuration file.
Command Purpose
Step 1 configure terminal Enters global configuration mode.
Step 2 ip dhcp poolname Creates a name for the DHCP Server address pool, and enters DHCP
pool configuration mode.
Step 3 bootfile filename Specifies the name of the configuration file that is used as a boot
image.
Step 4 network network-number mask
prefix-length
Specifies the subnet network number and mask of the DHCP address
pool.
Note The prefix length specifies the number of bits that comprise
the address prefix. The prefix is an alternative way of
specifying the network mask of the client. The prefix length
must be preceded by a forward slash (/).
Step 5 default-router address Specifies the IP address of the default router for a DHCP client.
Step 6 option 150 address Specifies the IP address of the TFTP server.
