Feb. 8, 2014 - PRLog -- There are 3 level for Cisco IOS: level0, level1, level15

The level0 has 5 commands, level1 is about 40 orders, the rest are in level15.

Router#enable 0

Router>?

Exec commands

Enable Turn on privileged commands

Exit Exit from the EXEC

From the level0 into the level1 prompt for password not set.

Set password for level1:

% Converting to a secret. Please use "enable secret" in the future

Say it plain text display, but the IOS automatically converts password to secret.
