Working with very large config files
|

| SkyFox 2004-03-24, 1:25 pm |
| Hi all,
I have to deploy a configuration that definitely *can't* fit into the 55K of
NVRAM (Cisco 3725 platform), because of a huge number of tunnels interfaces.
I searched thru the CCO and found a "boot config filename" command that only
exists on IOS 12.1 and below. This command allows to boot from a
startup-configuration located in flash rather than in NVRAM.
However, I can't find a similar command with 12.2 and 12.3 releases.
Do you have any experience / idea about this issue?
Many thanks!
(I'm sorry if this thread is slightly OT in this group!)
Best Regards.
Olivier

| Try 'service compress-config'
I posted earlier in this group about this command,
alas to no avail.

Service compress-config, as others have suggested, will cover you
if the config file isn't too big.
If you really want to load a BIG config, then yes, you can load it
from your flash. Use this to load the config file stored as
flash:foo
service config
boot host tftp foo 171.68.186.53 ! 171.68.186.53 is the local E0
address
tftp-server bootflash:foo.tmp alias foo
The most robust approach is to TFTP load from a local loopback address.

| Another, I suppose undocumented, way to load config from flash is:
service config
boot host flash:mybigconfig
Configuration on flash should contain 'no service config'. Otherwise router
will try to load config from tftp://255.255.255.255 all the time.
Config from flash will be added to the config first loaded from NVRAM, so
you can utilize both.
