Using the SDM to Aback Up, Restore, and
Edit the Router’s Configuration
Honestly, there absolutely isn’t annihilation appropriate about how the SDM handles configurations on a
router. Basically, if you were to telnet to a router, accomplish a appearance run, and archetype this output
to a argument book on your PC, you’ve aloof performed (more or less) what SDM and its configuration
management accoutrement can do. But this is still a beneath ambagious way to administer files than accomplishing so
through the Cisco IFS.
Why? Well, what’s easier about application the SDM rather than the archetype command we covered
earlier in this affiliate is that no TFTP host is needed. By application the SDM, you can affix via
HTTP or HTTPS to a router and accumulate all files bounded on your PC instead of accepting to configure
a TFTP host.
Let’s booty a quick attending at how the SDM can aback up and restore your agreement from
your host. From the capital menu, accept Book Write to Startup Config to aback up your configuration
to NVRAM.
Then accept Book Save Running Config to PC.
One aftermost advantage for managing your files is to use the Agreement Administration screens
under Additional Tasks.
The Config Editor allows you to change the running-config, but afore it will let you do that,
you accept to accede that you can spiral up your router’s agreement and that this is OK with you!
It’s best to bang the Save Running Agreement button. You can again accept to acceptation the
file from RAM or from your PC.
Last, from Agreement Management, you can accept Reset to Factory Default. This will
place the HTTPS administration aback on the router.
As you can see, there are abounding altered means to spiral up, umm, I mean, change the files
in flash, NVRAM, and alike RAM.
