I have a superadmin account in ACS.
with this account i can able to login GUI but can't able to login CLI mode.
what could be the problem ?
You've already created a CLI admin account during the first setup of ISE. If you forgot the CLI admin password you can perform "password recovery" by booting from ISE DVD and choosing option 3 or 4.
The ACS GUI Administrator accounts and CLI Administrator accounts are different. You cannot login with GUI accounts into CLI.
You need to use CLI created accounts to access the ACS command line. You should have created one when first installing the ACS 5.x.
