Hi,
The solution is to use the boot buffersize size configuration command in order to increase the size of the simulated NVRAM. The configuration file cannot be larger than the buffer size allocation. The range is from 4096 to 524,288 bytes.
The boot buffersize command simulates a larger NVRAM.

Dear VJ
I had one confusion
is it like if i issue
router# copy running-config flash:newconfig.cfg
Destination filename [newconfig.cfg]?
31585 bytes copied in 3.552 secs (10528 bytes/sec)
router(config)# boot config-file flash:newconfig.cfg
commands then i don't need to configure
boot buffersize size
or both are necessary
kindly advise
Regards!!

Hello,
Both methods are not required. Saving to flash is a "work around" and modifying the buffer size is the solution.
If the switch can be reloaded I would say modify the buffer size and be done with it. If you need to wait, say for a maintenance window, to reload then saving the configuration to flash buys you the time you needed for the reload.

You can also use the 'Service Compress-Config' command.

To resolve this issue, perform this procedure:
If this error message is displayed when the Cisco IOS Software is upgraded on the Cisco Catalyst Fixed Configuration Switches 2900XL, 2940, 2950, 2955, 2970, 3500XL, 3550 and 3750, check the contents of the Flash to verify that enough free space is available for the new Cisco IOS Software image. Issue the dir flash: command to do this, as shown in this sample output:
c3548XL#dir flash:
Directory of flash:/
2 -rwx 109 Mar 05 1993 21:08:41 info
3 -rwx 1799001 Mar 05 1993 21:10:02 c3500xl-c3h2s-mz.120-5.WC5a.bin
4 drwx 640 Mar 05 1993 21:11:07 html
15 -rwx 109 Mar 05 1993 21:11:07 info.ver
17 -rwx 856 Mar 02 1993 03:07:04 vlan.dat
18 -rwx 2323 Mar 16 1993 23:17:22 config.text
19 -rwx 75 Jan 01 1970 00:00:35 env_vars
3612672 bytes total (387584 bytes free)
!-- The new image size should be less than the free space.
c3548XL#
In this example, only 387,584 bytes are available. Therefore, if any image that is larger than 387,584 bytes is copied to the Flash, the error message results.
To free up enough space to copy the new image, the existing Cisco IOS Software file must be deleted. To delete the file in this example, issue the delete flash:c3500xl-c3h2s-mz.120-5.WC5a.bin command. This frees another 1,799,001 bytes and leaves a total of 2,186,585 bytes available. As long as the new image is smaller than 2,186,585 bytes, the copy works.
The /recursive command option can be used to delete all files in the specified directory, as well as the directory itself.
Note: After the old Cisco IOS Software file is deleted, do not reload the switch until the new file is copied successfully to the Flash and the boot statement is updated. The switch fails to load an image if the upgrade procedure is not followed properly
