Set Enable password

This is the password you have to enter, when logged into the switch thru ssh/telnet/console and then try to go to priviliged  mode.
To save the password unencrypted do:

Linuxsource-Switch1# configure terminal 
Enter configuration commands, one per line. End with CNTL/Z.
Linuxsource-Switch1(config)# enable password cisco

Better to use encryption, so do:

Linuxsource-Switch1# configure terminal 
Enter configuration commands, one per line. End with CNTL/Z.
Linuxsource-Switch1(config)# enable secret cisco
The enable secret you have chosen is the same as your enable password.
This is not recommended. Re-enter the enable secret.
Linuxsource-Switch1(config)# wr

Beware! 🙂  the warning shown above..  .It doesn’t tell you the password hasn’t been set. (if the password is the same…!!)
