Hi,
Basicly you need following lines;
delete interface-range wireless-ap-ports member-range
set interface-range wireless-ap-ports member-range ge-4/0/37 to ge-4/0/47
set interfaces ge-4/0/36.0 family ethernet-switching port-mode access vlan members VLAN-NAME
By the way,
If you using 12.3xx version, lets say one of the ports are configured within range and it's configured single, the single configuration will override the range config. For example if you have following 3 lines;
set interface-range wireless-ap-ports member-range ge-4/0/36 to ge-4/0/47
set interface-range wireless-ap-ports unit 0 port-mode trunk vlan members [ Wireless CSMSBYOD ]
set interfaces ge-4/0/36.0 family ethernet-switching port-mode access vlan members VLAN-NAME
ge-4/0/36 interface will be a access port. But this is a dangerous configuration, because one day you decide to upgrade your device to 15.xx version -while those 3 lines are in configuration- ethernet switching of device wil stop, it's like a bug or something.
My opinion is never use range configuration.
I hope it is clean.
