Hi,


I am using shared secrect key as for example cisco123cisco or [email protected] when i enter such key in radius configuratio  and on acs server user is not able to log in to the switch and shows authentication fail in acs failed report. But when I enter cisco123 then its start working. Current version of acs solution engine is 4.1.23. Please help to resolve this issue. This seems to be abnormal behaviour. If any wirk around or an upgrade is requred pl update. Thanks in adv.

ACS works with special character in shared sceret key.


Could you please delete the AAA client from the network configuration and re-add it using shared secert key [email protected] and try again.


Few Facts:


Key—The shared secret of the AAA server. Maximum length for AAA server keys is 32 characters.


For correct operation, the key must be identical on the remote AAA server and ACS. Keys are case sensitive. Because shared secrets are not synchronized, you could easily to make mistakes when entering them on remote AAA servers and ACS. If the shared secret does not match, ACS discards all packets from the remote AAA server.


You may refer ACS doc:
