Scheduling a Reload of the Software Image Chapter 5 Assigning the Switch IP Address and Default Gateway Table 5-5 Environment Variables (continued) Variable CONFIG_FILE CONFIG_BUFSIZE Boot Loader Command Cisco IOS Global Configuration Command set CONFIG_FILE flash:/file-url boot config-file flash:/file-url Changes the filename that the software uses to read and write a nonvolatile copy of the system configuration. Specifies the filename that the software uses to read and write a nonvolatile copy of the system configuration. This command changes the CONFIG_FILE environment variable. set CONFIG_BUFSIZE size boot buffersize size Changes the buffer size that the software uses to hold a copy of the configuration file in memory. The configuration file cannot be larger than the buffer size allocation. The range is from 4096 to 524288 bytes. Specifies the size of the file system-simulated NVRAM in flash memory. The buffer holds a copy of the configuration file in memory. This command changes the setting of the CONFIG_BUFSIZE environment variable. You must reload the switch by using the reload privileged EXEC command for this command to take effect. Scheduling a Reload of the Software Image You can schedule a reload of the software image to occur only on an LRE switch at a later time (for 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 all switches in the network). Note A scheduled reload must take place within approximately 24 days. Configuring a Scheduled Reload 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. • 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-hour 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. 5-16 Catalyst 2950 and Catalyst 2955 Switch Software Configuration Guide 78-11380-10
