Wipe out an ASA

johnlloyd_13 — Tue, 12 Mar 2019 06:16:47 GMT

hi all,

just a quick one. what's the 'best' and practical way of resetting an ASA?

this is to help me configure the box from scratch.

is it by using the write erase or config factory-default command?

can elaborate between the two and which is more commonly used?

Write erase and reload will

Write erase and reload will erase everything on the ASA

Factory-default will leave the ASA with some default ip addresses and dhcp, you can also configure your own ip address to inside interface in the factory-default command.

Check this link:

We mostly use write erase when configuring ASA from the scratch.

Hi can you confirm which command you used which didn't delete the licenses?

What causes the policy-map global_policy with default inspection to be missing from the config file? A write erase and reload is restoring the missing global policy or configure factory default but why it is missing in some cases when as ASA is rebooted.

I appreciate any feedback.

Thanks,

I've seen it happen as a result of a bug on an FTD device. Re-entering the commands (could do it from cli config mode on ASA, have to use Flexconfig in FMC for FTD) restores them.
