KCT has been backing up my Cisco IOS configs for years ... then along comes a Cisco ISE 3.x Appliances. FWIW ISE 3.0 runs on a hardened RHEL 7.6, while ISE 3.2 runs on a hardened RHEL 8.4.
ISE 3.0 backs up defined as a Cisco.Switch.IOS. ISE3.2 doesn't play nice at all. Anybody have a good place to start?
