Using the SDM to Administer the
Flash Memory
I was activity to alarm this area “Using the SDM to Upgrade, Restore, and Back Up the IOS on
Your Router,” but the SDM allows administration of all the files in beam anamnesis (as able-bodied as
NVRAM), not aloof the IOS. It can be an easier adjustment of beam book management, but for what
it’s worth, you won’t acquisition it safer to do it this way. It is a way to administer your files, though.
Let’s analysis it out.
I’m activity to affix to an 1841 router (named R3) and advancement that IOS application the SDM.
Let’s affix and see what’s in flash. Looking at the aboriginal screen, we can see that IP is the only
feature accessible and that Firewall, VPN, IPS, and NAC are “X’d” out. Let’s fix that!
The abutting awning shows how to accessible the book administration for flash. Chose Book File
Management.
At this point, the awning shows all the files in flash, and we can see that we accept the
“ipbase” IOS.
Click Amount book from PC on the top of the awning to add a new file. When I approved to amount the
new IOS, I accustomed the bulletin apparent next.
I clicked OK, approved to annul the absolute file, and afresh accustomed this message.
I chose Yes and afresh looked at the Book Administration window afresh to verify that the file
was deleted.
I afresh chose Amount Book from PC again, and the book started uploading into beam memory.
Finally, success!
After rebooting, we can see that IP, Firewall, VPN, IPS, and NAC are all accessible with this
new IOS!
