Hi, i run IOS (tm) 7200 Software (C7200-JS-M), Version 12.1(8), RELEASE SOFTWARE (fc1) and i put a tacacs-server key PASS but even though i run service password-encryptio it does not encrypt the password. What might be the problem?
What you are seeing is normal behavior for the version of code that you are running. The set of keys that are encrypted by service password-encryption has changed over time. More recent versions of IOS do encrypt the TACACS server key and the version of code that you are running does not. If it is important to you to have the TACACS server key be encrypted then you should plan to upgrade the version of code to a more recent version of code. I do not remember for sure the version where the TACACS key became encrypted but I believe that it was somewhere in 12.3T.
