And follow the instructions it gives you

I need to replace exiting config, i don't want to merge, i want to erase current startup-config and restore backup startup-config

It will not be merged, it will be overridden. Once you copied it to your ASA, save it with "wr mem" command. You config will be replaced with the new one

it sounds like you're copy/pasting the config into the console instead of actually doing the tftp, but i may be mis-reading it.

in this case if you want to totally blow away what's running and restore the backed up config do this

erase start

copy tftp start
(supply tftp host, file name, etc)

when complete type the reload command
it will probably tell you the running config is different than the startup and ask you to save, don't save and just proceed with reload. when it boots back up you'll be running the config you restored

fqasimzade - Yes

Dangle79 - by doing this, will it bring down the internet?

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Hm, Dangle79 is correct, if you copy it from tftp, it does not merge, it replaces config

If you erase config without reboot, you will not lose your internet connection. Your old config will still be there (running config) Only your startup config will be erased

sorry, yes, write erase is the correct command. i wasn't speaking "asa"

> enable
(supply enable password)
# configure terminal
(config)# write erase
(config)# end
# copy tftp startup-config
Address or name of remote host []? (enter the ip of your tftp server)
Source filename []? (your backup file name)
Destination filename [startup-config]? (just hit enter if it says startup-config, otherwise type it there)

You should see something like this
Accessing tftp://172.16.11.50/startup-config…!!
Writing system file…
!!
5277 bytes copied in 0.470 secs

then it will return to the enable prompt, type "reload" and confirm

yes this will take down your connection while the asa is rebooting, but i believe there's no way to clear the running config while the asa is functional, you could only merge
