Chapter3 Assigning the Switch IP Address and Default Gateway Scheduling a Reload of the Software Image

When the switch is connected to a PC through the internal Ethernet management port, you ca n download

or upload a configuration file to the boot loader by using TFTP. Make sure the environment variables in

Table 3 -5 are configured.

Scheduling a Reload of the Software Image

You can schedule a reload of the software image to occur on the switch a t a l ate r ti me (f or example, late

at night or during the weekend when the switch is used less), or you can synchronize a reload

network-wide (for example, to perform a software upgrade on al l sw itche s in t he n etwor k) .

Note A scheduled reload must take place within approximately 24 days.

To configure your switch to reload the software image at a later time, use one of these commands in

privileged EXEC mode:

•reload in [hh:]mm [text]

This command schedules a reload of the software to take affect 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 in a string up to 255 characters in length.

To reload a specific switch in a switch stack, use the reload slot stack-member-number privileged

EXEC command.

•reload at hh:mm [month day | day month] [text]

This command schedules a reload of the software to take place at the specified time (using a 24-hou r

clock). If you specify 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.

Table3-5 Environment Variables for TFTP

Variable Description

Note We recommend that you do not modify this variable.

However, if you modify this variable after the boot loader is up or the value

is different than the saved value, enter this command before using TFTP.

IP_ADDR Specifies the IP address and the subnet mask for the associated IP subnet of

the switch.

DEFAULT_ROUTER Specifies the IP address and subnet mask of the default gateway.
