Thank you all for your help but it is still no clear for me.
so en cli, every option that comes up when we type show context, it shows a override ?
for instance
ap7632-XXX(config-device-XXX)#show context
ap7632 XXX
use profile XXX
use rf-domain XXX
hostname ap7632-XXX
interface vlan1 no ip dhcp client request options all
In the CLI - when you execute command 'show run' you can see the overrides at the end of running configuration,
to remove them:
rfs4000-1C0BD8#en
rfs4000-1C0BD8#config
Enter configuration commands, one per line. End with CNTL/Z.
rfs4000-1C0BD8(config)#
rfs4000-1C0BD8(config)#remove-override all
rfs4000-1C0BD8(config)# com w
