Changing dhcp ranges

Hi guys!

I was trying to change my start-stop dhcp range but i got an error trying to commit this following command:

delete service dhcp-server shared-network-name Test subnet start stop

and the error message that i got is :

Stop DHCP lease IP not defined for Start DHCP lease IP ‘’
DHCP server configuration commit aborted due to error(s).

What am i doing wrong? I tried stoping DHCP service with “disable” parameter and i still get that error message :confused:

Can you helpme guys?

you may have to issue multiple delete commands
do a show service dhcp-server to see what config is still there
