4. Save the configuration file to your startup configuration. This step
saves the configuration to NVRAM.
copy running-config startup-config
In this example, the buffer size is set to 50000 bytes:
Router1# configure terminal
Router1(config)# boot buffersize 50000
^Z
Router1# copy running-config startup-config
Verify the Image in Flash Memory
Before booting from Flash memory, verify that the checksum of the
image in Flash memory matches the checksum listed in the README
file that was distributed with the system software image. The check
sum of the image in Flash memory is displayed at the bottom of the
screen when you issue th
copy tftp flash command. The RE
ADME file is copied to the network server automatically when you in-
stall the system software image on the server.
Note: If the checksum value does not match the value in the
README file, do not reboot the router. Instead, issue the
copy command and compare the checksums again. If the
checksum is repeatedly wrong, copy the original system
software image back into Flash memory before you reboot
the router from Flash memory. If you have a corrupted
image in Flash memory and try to boot from Flash, the
router will start the system image contained in ROM
(assuming that booting from a network server is not
configured). If ROM does not contain a fully functional
system image, the router will not function and must be
reconfigured through a direct console port connection.
Display System Image and Configuration Information
Perform these tasks in EXEC mode to display information about sys-
tem software, system image files, and configuration files:
1. List information about Flash memory, including system image
filenames and amounts of used and remaining memory.
