How to configur a port range on Cisco switch

I have a Cisco 2960 –x Switch that I am trying to configure. I am trying to have my ports resemble a the ports of an older switch I am replacing. The old switch port s is configured like so:

interface FastEthernet0/7
 description TN-C2-WAP-01
 switchport mode trunk
 spanning-tree portfast
 spanning-tree bpdufilter enable
 spanning-tree bpduguard enable
interface FastEthernet0/8
 switchport mode access
 spanning-tree portfast
 spanning-tree bpdufilter enable
 spanning-tree bpduguard enable
On the new interface my interfaces are config like this:
 interface GigabitEthernet1/0/7
interface GigabitEthernet1/0/8

I was trying to configure a port range but I am not able to this is the CMD I was trying to use
TN-C2-SW02(config)#interface range gigabitethernet1/1-21 but no luck. Is this possible?

Try "interface range gi1/0/1-21" instead.
