ACS 5.4 user details



 I have just install ACS 5.4 on VMware,  during the installation I created a username (admin) with a password,    now after installation is finished,  I can use that  Username & Pass  in the CLI of my ACS config,     but when I access and open ACS through  https://x.x.x.x,   and try logging in through that Username & Pass,  but it does not work



Any issue?? plz help me


Users cannot login to the ACS

Users cannot login to the ACS GUI and this error message is received:

"The ACS runtime process is not running on this instance at this time. Changes can be made to the ACS configuration (these will be saved in the database), but changes will not take effect until the runtime process is restarted."


Manually restarting the runtime process from the CLI and rebooting the appliance resolves this issue. This is a minor issue and does not create any performance issue for the ACS. There are two minor bugs filed to observe this behavior. For more information, refer to Cisco bug IDs CSCtb99448 (registered customers only) and CSCtc75323 (registered customers only) .

In order to restart the runtime processes manually, issue these commands from the ACS CLI:

  • acs stop runtime

  • acs start runtime

The "admin" user is only for

The "admin" user is only for CLI access.

There is a default GUI user called "acsadmin" that you can use for the initial GUI login, the password is "default" and you will be forced to change it on the first login.
